Tubkins: Name Clearance and Research Addendum

Prepared for Marc Lynde · July 24, 2026 · Preliminary research, not a legal opinion

Update, July 24, 2026: name selected (TUBKINS) and clearance executed.

After this report, the federal register was searched live in the USPTO Trademark Search tool, and the DIY common-law and Pennsylvania state searches (Path B) were run. TUBKINS came through clean and is the chosen name. The federal register, the Pennsylvania trademark and business registers, and the Class 3 goods wording are all settled; the single common-law hit was run down and found discontinued. See the new sections below: Clearance Executed and Handles and Amazon. The fifteen-name table is kept as the record of how TUBKINS was chosen. Note the July 24 correction in the white-space section: Baby Dove already sells a syndet baby bar, so mildness is not the differentiator and Unilever is the fast-follower risk. The character is the moat.

How to read this

Every candidate name was run through an independent agent that (1) searched for live U.S. trademarks in International Class 3 (soaps, cosmetics) and Class 5, plus common-law sellers on the open web, Amazon, and Etsy, and (2) checked domain availability by live RDAP and WHOIS lookup on July 24, 2026. Promising names then got a second, adversarial agent that re-ran the checks and tried to knock the verdict down.

One limitation, since resolved.

During the original agent run, direct reads of the USPTO register, Justia, and Trademarkia were blocked (HTTP 403), so the verdicts in the table below rest on search-index listings plus general web search rather than a full register pull. That gap has since been closed for the winning name: the USPTO register was searched directly and TUBKINS came back clean. See Clearance Executed. The other fourteen names were never re-checked against the register, so treat their verdicts as preliminary only.

Go / No-Go at a glance

Name	Verdict	.com	Best available domain	Key trademark finding	Next step
Tubkins	GO	available	tubkins.com (+ tubkins.baby)	No live Class 3 mark found; coined and distinctive. Only neighbor is Tubby Todd (shared "Tub-" prefix, distinguishable).	Register tubkins.com today; formal knockout search; file Class 3 intent-to-use.
Bathkins	GO	available	bathkins.com (+ bathkins.baby)	No live identical mark in any class; coined. "Bath" root is suggestive, not descriptive.	Register bathkins.com today; formal knockout search; file Class 3 intent-to-use.
Bubbo (concept name)	CONDITIONAL	registered	bubbo.baby, getbubbo.com, hellobubbo.com	No live exact Class 3 blocker (both BUBBO regs are dead/unrelated). Real risk is confusion with Babo Botanicals (near-identical sound, same baby-cleanser space) and Bubbsi (shared "Bubb-").	Viable only on an alternate domain, and only after a 2(d) confusion review against Babo Botanicals.
Sudz Buddies	CONDITIONAL	available	sudzbuddies.com (+ sudsbuddies.com)	Domains are clean, but SUDSY BUDDIES is a live, renewed federal reg (Class 21, cleansing puffs) and a live Etsy seller sells "Sudsy Buddies" kids soap.	Clean domain, but clear the SUDSY BUDDIES conflict before adopting.
Ducky & Co.	CONDITIONAL	available	duckyandco.com	SQUEAKY DUCKY (Reg. 5199471) is live in Class 3 for handmade soap bars, so a 2(d) refusal/opposition is a live risk. "Ducky" field is crowded.	Clean domain, but the Class 3 DUCKY soap reg is a real hurdle.
Scrub Cub	CONDITIONAL	registered	scrubcub.baby	Scrub Daddy runs a litigious "Scrub ___" family and there is an in-class concern. No live identical Class 3 blocker.	Needs domain workaround and a confusion review vs. Scrub Daddy.
Wiggle & Wash	CONDITIONAL	available	wiggleandwash.com	Downgraded on verification: WIGGLE is live in Class 3 (Reg. 7050972, the Wiggle cycling retailer).	Clean domain, but the Class 3 WIGGLE mark must be cleared.
Dot & Bubble	CONDITIONAL	registered	neither checked .com free; dotbubble.com is parked/for-sale	BUBBLE (Bubble Skincare) is a live Class 3 owner and active enforcer; Mr. Bubble also in the space.	Needs a domain purchase and a bubble-field confusion review.
Peekaboo Bar	CONDITIONAL	registered	peekaboosuds.com	No live Class 3 blocker (closest, "Peekaboo" for soap, is dead), but the "Peekaboo" field is crowded in commerce.	Domain workaround; crowded field lowers distinctiveness.
Squeaky	CONDITIONAL	registered	squeaky.baby	SQUEAKY CLEAN! (Reg. 4291942) is live in Class 3 for the exact goods (soap, baby hand soap, shampoo, body wash), plus a pending SQUEAKY CLEAN application.	No .com and a live in-class family; weak pick.
Puddle	CONDITIONAL	registered	puddle.baby	No live registered blocker, but Puddles (kids skincare, puddles.in) is a common-law user of a near-identical name for analogous goods.	Domain + common-law collision; not clean.
Sudsy	CONDITIONAL	registered	sudsy.baby	"Sudsy" is descriptive/laudatory for soap (likely 2(e)(1) refusal, Supplemental Register at best) and the "Suds/Sudsy" common-law field is crowded.	Weak, hard-to-defend mark. Not recommended.
Little Lather	CONDITIONAL	registered	littlelather.baby	LULLABY LATHER is a pending Class 3 application expressly covering baby bubble bath, shampoo, and soap. "Little Lather" is also descriptive-suggestive.	Domain taken + pending similar in-class mark. Weak.
Bubbaloo	CONDITIONAL	registered	bubbaloobaby.com	Two live, renewed Class 30 BUBBALOO bubble-gum registrations. Different class, but a well-known confection mark.	Cross-class confusion risk; not recommended.
Bumble & Bar	NO-GO	available	—	Bumble and bumble is live in Class 3, Bumble has filed to extend into Class 3 bath products, and Bubble Bar is a live Class 3 mark. Famous-mark territory.	Do not pursue.

What this means

Only Tubkins and Bathkins were clean on both axes (no live Class 3 blocker found and the primary .com plus the .baby available). Tubkins was selected, and has since been confirmed against the live register; Bathkins remains an un-re-checked runner-up.
Bubbo, the original concept name, did not clear. The .com is gone and, more importantly, it sits between Babo Botanicals and Bubbsi, two active brands in the exact baby-cleanser category, which is where confusion refusals actually come from.
Several names had a clean domain but a hidden trademark problem (Sudz Buddies, Ducky & Co., Wiggle & Wash), and several had a clean-looking name but no obtainable domain (Squeaky, Puddle, Peekaboo Bar, Dot & Bubble). The adversarial pass is what surfaced the live Class 3 marks behind Wiggle & Wash and Sudz Buddies; the first-pass read had missed them.

Status: TUBKINS was selected and its knockout search has been run and is clean. The concern flagged here originally, that a recently filed intent-to-use application could be lurking with no web footprint, was the reason for the live register search recorded below. It found nothing. What is still outstanding is a professional full clearance search before any tooling or inventory spend.

Research Addendum

1. Fact-check of the pitch's load-bearing numbers

Safe to keep as written: Dr. Squatch's >$400M annual sales; Scrub Daddy's $1B+ lifetime and ~$340M 2024 revenue; the 360iResearch baby-bath figures ($4.57B in 2025 to $7.44B by 2032); Hello Bello's ~$179M revenue and October 2023 Chapter 11; and Babylist's "more than half of first-time parents," 9M customers, ~$900M GMV.

Three corrections to make before the deck goes out:

The Unilever / Dr. Squatch deal has closed. Agreed June 23, 2025, completed November 16, 2025. Change "agreed to acquire" to "completed its acquisition." This strengthens the slide.
Soften the Hello Bello price from $66.8M to the widely reported ~$65M.
Label the market-size definition. The global figure ($96B to $175.2B, Market.us) sits next to a narrow figure of ~$6.7B (Fact.MR / FMI). The 14x gap is definitional (whether diapers, wipes, and food are counted). Say so, or a sharp reader reads it as cherry-picking. The cleanest single number to lead with is the baby-bath slice: $4.57B in 2025 at 7.2% CAGR.

Optional refreshes for current numbers: Scrub Daddy lifetime sales are now cited at ~$1.3 to 1.4B, and Babylist GMV has reportedly passed $1B.

2. Is the white space still open? (mid-2026)

Yes. No major baby brand sells a fun, character or mascot-driven solid cleansing bar for babies. Every major-brand baby bar (Johnson's, Baby Dove, Mustela, and the notable recent Cetaphil Baby toddler bar) is plain, clinical, and function-first. The leading DTC names (Frida Baby, Pipette, Tubby Todd) have no bar at all, only liquid washes. "Fun character" soap exists only in two disconnected pockets: unbranded indie Etsy/Amazon animal-shaped bars aimed at older kids as gifts, and licensed-character bubble bath, bath toys, and plush soap-holders (SoapSox).

Closest recent competitor: the Cetaphil Baby Gentle Cleansing Bar, a new mass-market toddler bar. It validates that a major sees room in the format, but it is plain and character-free, so it does not take the lane; it raises the odds an incumbent could.
The concept is not novel, only unoccupied. Disney sold a character-faced "Cameo" bar in the 1990s (discontinued). Barriers are low, so an indie seller could scale into this. The moat has to be brand, character IP, and retail/registry relationships built fast.

Correction, July 24, 2026: mildness is not the differentiator. Only the character is.

Ingredient labels were read directly for the bars actually on shelf. The result changes the pitch, though not the strategy. Baby Dove already sells a syndet-led bar for infants (its list opens with Sodium Lauroyl Isethionate), and the Cetaphil bar leads with Sodium Cocoyl Isethionate. So a genuinely mild baby bar already exists, and any claim to be the first one is wrong. What remains unoccupied, and what was always the real thesis, is that not one of them has a face.

What is actually on the shelf

Product	Leads with	Chemistry	Character?
Johnson's Baby Bar	Sodium Tallowate, Cocoate, Palm Kernelate	True soap, pH ~9 to 10	No
Dr. Bronner's Baby	Organic oils + Sodium Hydroxide	True soap (castile)	No
Yardley	Sodium Tallowate / Palmate	True soap	No
Baby Dove Rich Moisture	Sodium Lauroyl Isethionate	Syndet-led combar, skin pH	No
Cetaphil Gentle Cleansing Bar	Sodium Cocoyl Isethionate	Syndet-led combar	No
Tubkins	Syndet, pH ~5.5	Syndet	Yes

The label tell, for reading any bar in five seconds: "Sodium [fat]-ate" (tallowate, palmate, cocoate, palm kernelate), or oils plus sodium hydroxide, means saponified true soap at pH 9 to 10. Isethionate, sulfosuccinate, glycinate, or taurate means syndet at pH 5.5 to 7. The Dove Beauty Bar is the canonical syndet.

3. Manufacturing and MoCRA regulatory status

The manufacturing and regulatory foundations are sound and current. All four named manufacturers check out, with caveats:

RainShadow Labs is genuinely low-MOQ but is a liquid/skincare house; bar/syndet-bar capability is unconfirmed. This is the weakest link if you were counting on it for the bar itself. Verify before relying on it.
Twincraft's "Baby Bar" is real, but its copy calls it high-glycerin/gentle rather than explicitly syndet. Confirm the base chemistry on a call, because the whole plan depends on a true syndet at pH ~5.5.
Stephenson Syndopal (extruded syndet, pH 5.5 to 6.5) and Syndopour (melt-and-pour) are both real and current. Syndopour is marketed as a shampoo base, so confirm fit for a bar.
Vanguard Soap (custom bases, novelty dies, in-house formulation) is confirmed and well-suited.

Regulatory core is locked and unchanged: a syndet bar making cosmetic claims is a cosmetic under FDA/MoCRA, not a CPSC "true soap" (21 CFR 701.20). Facility registration and product listing have been enforced since July 1, 2024, and the first biennial registration renewal window opened July 1, 2026. Responsible-Person label contact and 15-day adverse-event reporting apply now.

Three moving pieces since the original memo: the cosmetics GMP proposed rule has stalled onto FDA's Long-Term Actions list; the talc asbestos-testing rule was withdrawn November 28, 2025; and the fragrance-allergen disclosure NPRM, targeted for May 2026, cannot be confirmed as published as of July 24, 2026 (treat it as still pending).

Technical feasibility is not in doubt, and is now better than "not in doubt": a tear-free, pH ~5.5 mild syndet bar built on sodium cocoyl isethionate ("baby foam") plus supporting gentle surfactants is a mature, established product, and Baby Dove ships exactly this chemistry for infants at national scale today. The formulation question the original memo called the concept-killer has effectively been answered by a company with far more to lose. "Tear-free" is still substantiated by ocular-irritation testing, not by the label phrase.

4. Competitive risk: Unilever holds both halves

This is the most serious risk in the package and it was not identified in the original research. Unilever owns Baby Dove, which means they already manufacture a mild syndet bar for infants at scale. In November 2025 they closed the $1.5B acquisition of Dr. Squatch, which bought them the personality-led, character-forward bar-soap playbook. They therefore hold both halves of this concept already, and pressing a face into a bar they currently produce is not a difficult project for them.

What this rules out: any pitch built on chemistry or mildness leadership. That ground is taken, and an operator will know it.
What survives: the character IP. Named characters, artwork, and a registered trademark are ownable in a way a surfactant blend is not. This was always the memo's stated thesis ("a character brand that happens to sell soap"), so the strategy is intact even though the framing must change.
What it implies for pace: move first, register the IP early, and take registry and specialty distribution while a company that size is still deciding whether a four dollar novelty justifies a line review.
The upside reading: a strategic acquirer who already owns the chemistry and the playbook, and lacks only the character, is a natural buyer. That is the exit the concept was built for.

TUBKINS: Clearance Executed (July 24, 2026)

After the report above, the register was searched directly rather than through indexes, which closes the "register read was blocked" limitation. TUBKINS is now a high-confidence GO.

Federal register (USPTO Trademark Search, run live)

Exact mark "tubkins": zero results, live and dead, in every class.
"tubk*" (the whole prefix family): zero results, live and dead. This sweeps tubkin, tubkinz, tubkings, and tubkens.
Wildcard validated: "tubby*" returned 119 records (31 live), which proves the zero on "tubk*" is real and not a broken search. The "tub-" bath field does have live players (MR TUBBY is live in Class 3 bath soaps, and Tubby Todd is in the space), so any future §2(d) pushback would come from that "tub" direction. TUBKINS is a distinct coined word and the prefix is empty, so the risk reads low.

Path B: common-law and Pennsylvania state searches

Common-law web sweep: "Tubkins" is almost entirely non-commercial noise (a pet lizard, a cat, gaming handles, 1800s newspapers). One commercial hit surfaced and was run down.
The one hit, Sunrise Soap Company (York and Gettysburg, PA), verified and deflated. An eight-year-old Facebook post used "Tubkins" for toy-surprise bath bombs. But their entire current online catalog carries no product named "Tubkins" (their bath bombs sell as "3-inch Bath Bombs" and "Bath Fizzies by the Dozen"), and they hold no Pennsylvania trademark registration for it. Read: a discontinued legacy nickname, not a live mark. Extended non-use is prima facie abandonment of common-law rights (15 U.S.C. §1127). Risk: low. One confirmatory step remains, since only the online catalog was reviewed: confirm non-use by a call, an in-store check, or the Wayback Machine.
Pennsylvania trademark register: no results for "tubkins."
Pennsylvania business entity register: no results for "tubkins."
Other states: California keeps trademarks outside its online business portal, which is typical. Comprehensive multi-state plus design and phonetic coverage is what the professional clearance search buys.

Class 3 goods, locked against the ID Manual

Verified in the USPTO Trademark ID Manual on July 24, 2026. File exactly:

International Class 003: Non-medicated soaps for babies; baby shampoo

Non-medicated soaps for babies, ID Manual term 003-1394, the body-cleansing bar.
Baby shampoo, ID Manual term 003-1404, the hair-cleaning function (the bar cleans hair and body).
Both are pre-approved entries, so no free-form surcharge. Do not write "bar": "cleansing bar" returns zero ID Manual records, because soap is described by what it is, not by its shape.

Domain

tubkins.com is secured (registered through Cloudflare). tubkins.baby was left open by choice (about $50 per year, recurring, optional). hellotubkins.com and gettubkins.com remain available as defensive grabs.

Social Handle and Amazon Availability (July 24, 2026)

The exact "@tubkins" is mostly taken, so the recommendation is one consistent variant across every platform: tubkinsbaby, which is open everywhere checked.

Platform	@tubkins (exact)	tubkinsbaby (recommended)
Instagram	Taken (dormant park)	Available
TikTok	Taken (active personal)	Available
X / Twitter	Taken (dormant since 2009)	Available
YouTube	Available	Available
Facebook (vanity URL)	Taken (personal profile)	Set on Page creation
Amazon brand "Tubkins"	Clear. No seller or product uses it; enroll in Brand Registry once the mark registers, or via IP Accelerator on a pending application.

Claim tubkinsbaby on Instagram, TikTok, X, and YouTube in one sitting for a consistent set, and grab @tubkins on YouTube defensively, since it is the one place the exact name is free. Account creation needs your own email, phone, and (for Amazon) tax and bank details, so those steps are yours to complete.

Recommended next steps

Status as of July 24, 2026: the federal and Pennsylvania register knockouts are done and clean, the goods are locked, tubkins.com is secured, and the handle plan is set. What remains:

Confirm Sunrise Soap's non-use of "Tubkins" (a call, an in-store look, or the Wayback Machine). Low effort, and they are local to you.
Order a professional full clearance search (Corsearch or CompuMark) before committing to tooling and inventory. It covers all fifty states, common-law use, and design and phonetic marks that the DIY sweep cannot.
File the §1(b) application for TUBKINS in Class 3 with the locked goods, through Trademark Center. The shell is drafted and ready.
Claim the handles (tubkinsbaby across platforms, plus @tubkins on YouTube).
Strip every "first gentle bar" claim from the deck and any pitch materials. Baby Dove got there. Lead with the character and the collectible cast instead, and name Unilever as the fast-follower risk before your audience does.
Update the pitch deck: Dr. Squatch deal "completed Nov 2025," Hello Bello ~$65M, and a market-definition label on the sizing slide.
Manufacturer diligence: put the syndet-chemistry question to Twincraft and Vanguard first, and treat RainShadow as liquid-only unless they confirm bar capability. Ask them directly to benchmark against the Baby Dove bar, since that is now the reference product.

Generated from a 32-agent clearance and research workflow, then extended July 24, 2026 with live searches of the USPTO Trademark Search and ID Manual, the Pennsylvania trademark and business registers, social and marketplace availability, and direct reads of competitor ingredient labels. Findings are preliminary and not a legal opinion; register and availability results were current as of that date. A professional full clearance search is still recommended before committing spend. Where an earlier finding has since been corrected, the correction is marked in place rather than deleted.
