Shop
The Collection
Three formulas. One standard. Each tube carries a batch code tied to published laboratory reports.
$24.00
Film-forming tubing formula. Smudge-resistant wear. Removes with warm water and gentle pressure, no remover needed.
Brown primer / Black mascara
$32.00
Double-ended: brown tubing primer on one side, black tubing mascara on the other. Use one or both.
Why the price
Every batch is tested for preservative effectiveness, microbial limits, and heavy metals before it ships, and the reports are on this page. That's what you're paying for.
The Science
What 'Tested' Means Here
Mascara is the highest-risk product in your makeup bag. It's water-based, it sits next to your eye, and the wand goes in and out of the tube for months. That's why we test every batch, and why we show you the results.
Preservative Effectiveness (Challenge Test)
The formula is inoculated with bacteria, yeast, and mold and must reduce them over 28 days. This is the test that matters most for anything near the eye.
Reports appear here as each batch is released.
Microbial Limits
Total count of bacteria, yeast, and mold in the finished product.
Reports appear here as each batch is released.
Heavy Metals
Lead, arsenic, cadmium, mercury, and chromium by ICP-MS. Black pigments (iron oxides, carbon black) are where these show up.
Reports appear here as each batch is released.
PFAS Screening
By LC-MS/MS, because California and other states now restrict intentionally added PFAS in cosmetics.
Reports appear here as each batch is released.
Stability
The formula holds its performance and doesn't separate over its shelf life.

Formula types
Tubing vs Traditional Mascara
Two ways to put color on a lash. One coats, one wraps. Here's how they compare — by type, never by brand.
Warm water. Gentle pressure. The tubes slide off.
01
Waterproof vs washable — what the words really mean
Waterproof formulas use water-repelling waxes and solvents, so they need an oil-based remover. Washable formulas lift away with cleanser. Tubing sits between: it resists water and tears while worn, then releases in warm water as the polymer film softens.
02
Fiber mascaras
Short nylon or rayon fibers cling to the tips for the look of extra length. They can shed through the day, which matters if you wear contacts.
03
Lash primers
A primer lays down a base coat that gives the top coat more to grip, for a fuller look. Our duo pairs a brown tubing primer with black tubing mascara.
04
Why contact lens wearers prefer tubing
Traditional formulas can soften with tears and migrate. Tubing polymers set into a flexible film that holds its shape and comes off in pieces rather than dissolving. If anything irritates, stop use and see a doctor.
05
Brown vs black: how to choose
Black gives maximum contrast and definition. Brown reads softer — a good match for fair or light lashes, daytime, or lashes that look defined without looking done.

Formula anatomy
What's in a Mascara
1234567Water
The base. It carries everything else and evaporates as the film sets.
Film-forming polymers
Acrylates copolymer, VP/VA copolymer. They form the flexible tubes around each lash — why it resists smudging and slides off in warm water.
Waxes
Beeswax, carnauba, candelilla. Body and grip, so the formula clings to the wand and to lashes.
Pigments
Iron oxides, carbon black. The color. Black pigments are screened for heavy metals.
Emulsifiers
Keep water and wax blended into one smooth cream.
Thickeners
Set the texture so each stroke deposits an even coat.
Preservatives
Phenoxyethanol, ethylhexylglycerin, sodium dehydroacetate. They hold back the bacteria, yeast, and mold the wand introduces with every use.
Why carbon black is the black
Nothing else gives the same deep, neutral black. Because it's the pigment most likely to carry trace metals, it's the first thing we screen.
Why mascara needs a preservative
A water-based formula opened daily next to the eye is an ideal place for microbes. 'Preservative-free' near the eye would mean single-use packaging or a formula with no water at all.
Fibers: nylon and rayon
Tiny fibers that extend the tips for the look of length. Our tubing formulas don't rely on them.
Fragrance in mascara: usually none
Fragrance adds nothing to performance and is a common source of sensitivity, so most mascaras, including ours, leave it out.

Regulations
PFAS, MoCRA & the New Rules for Mascara
FDA identified PFAS in roughly 1,700 cosmetic products, including mascaras, and a wave of state laws now restricts intentionally added PFAS in cosmetics. California's Toxic-Free Cosmetics Act bans a list of ingredients outright. If you sell mascara in the US, this is your checklist.
Showing 8 of 8 regulations
MoCRA in one page
Facility registration. Product listing. Safety substantiation on file. Serious adverse event reporting within 15 business days. Labeling with a US contact for adverse events. Good manufacturing practice rules as FDA finalizes them.
What 'PFAS-free' has to mean on a label
The claim should be backed by a validated test on the finished product and supplier documentation for every ingredient — not just an absence of PFAS names on the INCI list.
Fragrance allergen disclosure
MoCRA directs FDA to require labeling of fragrance allergens. Until the list is final, know what's in your fragrance, or leave it out of eye products entirely.
This is general information, not legal advice. Confirm requirements with a regulatory attorney or consultant.
