For my inner circle, from Marc

The baby bar

A tear-free bar of baby soap with a face on it. Nobody has made bath time something a baby reaches for.

The idea

Take the most boring object in the nursery and give it a personality.

Every baby wash on the shelf is the same liquid in the same plastic bottle. Meanwhile bar soap has quietly come back, because it costs less per wash, travels better, and skips the plastic entirely.

So: a gentle, tear-free cleansing bar made specifically for babies, shaped like a friendly character with a face pressed into it. It cleans hair and body. It comes as a cast of characters in different colors, so there is a reason to collect them, gift them, and keep buying them.

This is not really a soap business. It is a character brand that happens to sell soap. That distinction is the whole thing.

Something a baby reaches for

Why it might work

The numbers are not the exciting part. The empty shelf is.

The wider baby personal care market gets quoted anywhere from seven billion to ninety six billion dollars depending on whether you count diapers and wipes, so I am using the narrow number above and ignoring the flattering one. Johnson's still sells a baby bar, but treats it as a leftover from 1970. Dove Baby, Aveeno, Cetaphil, Mustela, Tubby Todd, and Pipette are all liquid. Search the baby bar category on Amazon and you get castile soap and a wall of anonymous packaging. Nobody owns this.

The playbook already exists

Two people got rich adding a face to something nobody thought about.

01 / Scrub Daddy

A sponge with a smile

The face was not decoration. The mouth cleans utensils and the eyes clean glasses. Shark Tank, then QVC, then everywhere. Past one billion dollars in lifetime sales. It also runs licensed Disney shapes now, which is exactly the second act I have in mind.

02 / Dr. Squatch

Soap, but with a point of view

Picked an underserved audience, led with personality and content rather than chemistry, and sold to Unilever for one and a half billion dollars. The asset was the audience and the brand. The soap was almost incidental.

03 / Squishmallows

A cast beats a product

Distinct characters with names and personalities turn one purchase into a collection. Apply that to a four dollar consumable that gets used up every few weeks and the repeat purchase math becomes very friendly.

The cast

One shape, four friends, endless reasons to buy another.

Each character gets a color, a name, and a personality that maps to a variant. Sunny is the fragrance-free one for sensitive skin. Poppy is the calming lavender. Rounded shapes with no sharp edges and no small parts, which is both the friendly look and the safe one.

The brand

It already looks like a company, not a slide.

The mark is a bar of soap with a face pressed into it, sitting where the letter i belongs. It works in one color, forward and reversed, so it survives a carton, an embossed die, and a phone screen.

The Tubkins wordmark in navy on cream, with a smiling soap bar forming the dot of the letter i. The Tubkins wordmark reversed in cream on navy.

And it is ready to post. These are the launch tiles, built from the same four characters, which is the cheapest marketing a baby brand has: a face people want to share.

Social tile reading meet the tubkins, showing the four characters in a row. Social tile reading tear-free, gentle, kind of adorable, over the blue Tubkins bar. Social tile reading bath time, but softer, showing a child holding the bar in the bath.

The hard parts

Three real problems, and how each one gets solved.

A bar of soap is bad for baby skin

True, and this is the one that kills the idea if we get it wrong. Traditional soap runs at a pH of nine or ten and strips infant skin, which is why every baby wash is liquid.

The fix

It cannot be soap. It has to be a syndet bar, which is the same technology inside a Dove beauty bar, formulated to skin pH around 5.5 on gentle surfactants. Manufacturers already make exactly this. Stephenson sells a baby-suitable syndet base off the shelf, and Twincraft in Vermont and Vanguard in Memphis both produce bars at scale and hold hundreds of molds.

Babies put everything in their mouths

A small, colorful, toy-shaped object aimed at infants is a fair thing to worry about, and it is the first question any serious operator will ask.

The fix

Never embed a toy, which is where the actual recalls in this category come from. Make the bar larger than the federal small-parts cylinder, keep the form a single rounded solid with nothing that snaps off, and keep the formula low irritant so incidental mouthing is unpleasant rather than dangerous. A friendly shape is not a toy, and it should not pretend to be one.

Complicated shapes are expensive to make

Fully sculpted three dimensional characters have to be cast in molds, slowly, at a much higher cost per unit than the extruded bars that fill the drugstore aisle.

The fix

The hero bar is a rounded shape with the face pressed in as a relief, which runs on cheap high speed equipment. That is precisely what Scrub Daddy does. Save the fully sculpted characters for premium and limited edition drops, where the higher price covers the slower process.

The money

The margins are good, if we price it like a brand and not like soap.

LinePer bar
Retail price$8.99
Wholesale price$4.50
Cost to make and pack~$1.50
Margin selling direct~83%
Margin selling wholesale~67%

These are modeled figures, not quotes, and they need to be confirmed with a manufacturer. The real risk is not the soap cost, it is retail. Slotting fees and trade spend eat fifteen to twenty five percent of revenue, and Hello Bello went bankrupt in this exact category despite doing a hundred and seventy nine million dollars in sales. So the plan sells direct and through baby registries first, where the margin actually stays with us, and only walks into Target with proof in hand.

Rough capital to get to shelf: five hundred thousand to one and a half million dollars.

How it gets built

Nine to fifteen months from idea to something you can hold.

  1. Formulate and test 3 to 6 months

    Commission the syndet bar at pH 5.5, then pay for the eye irritation and dermatologist testing that makes the tear-free claim honest. This happens first, because everything else depends on it.

  2. Brand, mold, and clear the name runs in parallel

    Design the cast, cut the tooling, print the cartons, and file the trademark. The name is set: Tubkins, with the .com and .baby both open and no blocking mark found in a first-pass search.

  3. Launch direct, Amazon, and Babylist months 9 to 12

    Babylist runs the registry for more than half of first time parents. A cute character bar is close to a perfect baby shower gift, which is a far cheaper way to find customers than buying ads.

  4. Walk into retail with receipts year two

    Target and specialty baby once the velocity data exists. Character licensing after that, once there is enough volume to make a Bluey or Sesame Street deal worth signing.

What I actually want to do

Hand this to someone who can build it.

I am not going to manufacture soap myself. What I can do is take a finished idea to someone who already operates in this space, the research done, the risks named, and the brand fully designed, and see whether it gets someone excited enough to run with it.

You are one of a handful of people I trust that I am showing this to. The name is decided, Tubkins, and it has cleared trademark and domain checks. The brand is designed and the product you see above is real. All I want back is your honest gut read, and, ideally, to see you a little bit excited.

Three questions, if you have five minutes: would you buy it, who should I be talking to, and what is the part that made you wince?
