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.
- Shampoos 5 labels First five names: 1 of 5 Shampoos without it
- Stylers 1 label First five names: 0 of 1 Stylers without it
- Protein treatments 1 label First five names: 0 of 1 Protein treatments without it
