What it is

In the register’s words: “Glycine Soja Oil is the oil obtained from the soybean, Glycine soja, Leguminosae, by extraction or expression. It consists esentially of triglycerides of oleic, linoleic and saturated acids.”

EU register name (INCI)
GLYCINE SOJA OIL
CAS number
8001-22-7
EC number
232-274-4

Labels often add a second name in brackets, so a label may say Glycine Soja (Soybean) Oil where the register says GLYCINE SOJA OIL. 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) Oil 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.”

Perfuming

Used as a perfume or scent material. Essential oils and their scent compounds, such as linalool and limonene, carry this role.

Register definition: “Used for perfume and aromatic raw materials.”

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 (14)

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.
