Glycol Distearate is on 15 of the 177 hair-product labels we compare, from 12 makers, most often in shampoos. Its uses in the EU ingredient register include emollient, emulsifying surfactant and viscosity controlling. 6 of these labels name it among the first five ingredients.

The register’s chemical name for it: “Ethylene distearate.”

What the register lists it for

These are the uses the European Commission’s CosIng register lists for Glycol Distearate 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.”

Viscosity controlling

Makes a product thicker or thinner, so a gel holds its shape or a shampoo pours. Gums, cellulose and some salts carry this role.

Register definition: “Increasing or decreasing the viscosity (thickness) of cosmetics.”

Opacifying

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

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

Skin conditioning

The register’s broad role for ingredients that keep skin in good condition. On a hair label it often sits beside a hair role, or marks a plant oil or extract.

Register definition: “Maintaining the skin in good condition.”

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 (15)

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.
