Glycol Stearate

TheWashDay editorial · Updated · From the EU ingredient register and the makers’ own labels · How we match names

Jump to a section

Glycol Stearate is on 7 of the 177 hair-product labels we compare, from 6 makers, most often in shampoos. Its uses in the EU ingredient register include emollient, emulsifying surfactant and cleansing surfactant. One of these labels names it among the first five ingredients.

What it is

The register’s chemical name for it: “2-hydroxyethyl stearate.”

EU register name (INCI)
GLYCOL STEARATE
CAS number

What the register lists it for

These are the uses the European Commission’s CosIng register lists for Glycol Stearate in any cosmetic, hair roles first. They say why a maker might add it, not what it does in one formula, and they aren’t a safety rating.

Emollient

Oils, butters and similar ingredients that make a surface feel soft and smooth. On hair they coat the strand; many plant oils carry this role.

Register definition: “Acting as lubricants on the skin surface providing the skin with a soft and smooth appearance.”

Emulsifying surfactant

Lets oil and water mix into one cream or lotion and stay mixed. Conditioners and creams rely on them.

Register definition: “Helping suspensions or dispersions of liquids in a second liquid by reducing the surface tension of the substances to be emulsified.”

Cleansing surfactant

The washing ingredients: they let water lift oil, product and dirt off hair and scalp. Shampoos list them near the top; some conditioners hold a little.

Register definition: “Wetting body surfaces, emulsifying or solubilizing oils, and suspending soil (generally, such ingredients contribute to the foaming and lathering properties of cleansing products).”

Opacifying

Makes a product less see-through, which is why some shampoos and conditioners look creamy.

Register definition: “Reducing transparency or translucency of cosmetics.”

Where it sits on each label

US labels list ingredients from most to least, except that those at 1% or less may follow in any order. A name near the top is a large part of the formula. A label doesn’t mark where the 1% point falls, so further down, the order says little about how much is in it.

Every label, product by product (7)

Each line runs from the first name on a label to the last; a dot is where this ingredient sits. Makers change formulas now and then; if the list on your bottle differs, go by your bottle.
