What it is
In the register’s words: “Phytosterols is a complex mixture of sterols isolated from the higher plants.”
- EU register name (INCI)
- PHYTOSTEROLS
What the register lists it for
These are the uses the European Commission’s CosIng register lists for Phytosterols 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.
- 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.
- Shampoos 1 label First five names: 0 of 1 Shampoos without it
- Deep conditioners 1 label First five names: 0 of 1 Deep conditioners without it
- Leave-in conditioners 1 label First five names: 0 of 1 Leave-in conditioners without it
Every label, product by product (3)
- As I Am Coconut CoWash Cleansing Conditioner Shampoo 9th of 25 names
- As I Am Hydration Elation Intensive Conditioner Deep conditioner 11th of 29 names
- As I Am Leave-In Conditioner Leave-in conditioner 7th of 25 names
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.
