THE YB STANDARD

Considered, Traceable, Transparent.

We review the products we list against our own standard for ingredients, sourcing and packaging — so you don’t have to.

1,700+
Substances prohibited in EU cosmetics

That is the legal baseline every product must meet. Our own list goes further, across every category on this page.

THE LINE WE DRAW

Common across the beauty industry. Not in our curation.

What we say no to matters just as much as what we say yes to.

The ingredients below are permitted in the EU and appear widely across beauty. We apply a stricter line. That is a statement about our own selection, not about products that contain them.

Synthetic Fragrance

Scent compositions carried under the collective term ‘parfum’. Where a brand can tell us what is behind it, we publish it.

PEGs

Polyethylene glycol derivatives used as emulsifiers and solvents.

Synthetic Polymers

Silicones and solid microplastic particles, used for slip, film and texture.

Sulfates

Anionic surfactants that produce a dense lather.

Parabens

Esters of para-hydroxybenzoic acid, used to prevent microbial growth.

Phenoxyethanol

A glycol ether used as a broad-spectrum preservative.

Mineral Oils

Refined petroleum-derived emollients that slow water loss from the skin surface.

Chemical UV Filters

Oxybenzone, octinoxate, octocrylene and homosalate are not used as UV filters in the formulas we carry.

THE FULL LIST

Ingredients We Leave Out

Grouped by the job each ingredient does in a formula — preservation, texture, scent — rather than by chemical class. Ingredient names follow INCI nomenclature.

This list sets out our own selection criteria. It is not a safety assessment of individual ingredients.

Polymers and siloxanes give a formula slip, hold and a fast-drying finish. These are the ones we leave out.

Silicones
Dimethicone · Amodimethicone

04

Scent

How a product is scented, and how that appears on the label.

Undisclosed fragrance
Parfum · Aroma

‘Parfum’ and ‘aroma’ are collective terms permitted under EU labelling rules. Where a brand can tell us what sits behind them, we publish it on the product page.

Synthetic musks
Galaxolide · Tonalide · Musk ketone

Synthetic macrocyclic and polycyclic musks used as fixatives to extend how long a scent lasts. Not used in the formulas we carry.

05

Emollients, Solvents & Stabilisers

These ingredients carry actives, soften the skin surface and keep an emulsion stable.

Mineral oils
Paraffinum Liquidum · Petrolatum
