Ingredient on hair labels

Glycine Soja (Soybean) Sterols

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

Jump to a section

Glycine Soja (Soybean) Sterols is on 2 of the 177 hair-product labels we compare, all of them shampoos, from 2 makers. Its uses in the EU ingredient register are emollient and skin conditioning. None of these labels names it among its first five ingredients.

What it is

In the register’s words: “Glycine Soja Sterol is a mixture of phytosterols obtained from the Soybean, Glycine soja, Leguminosae.”

EU register name (INCI)
GLYCINE SOJA STEROLS
CAS number
-
EC number
-

Labels often add a second name in brackets, so a label may say Glycine Soja (Soybean) Sterols where the register says GLYCINE SOJA STEROLS. Both are the same ingredient.

What the register lists it for

These are the uses the European Commission’s CosIng register lists for Glycine Soja (Soybean) Sterols 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.”

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 (2)

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.
