What the register lists it for
These are the uses the European Commission’s CosIng register lists for Silk Powder 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.
- Bulking
-
Adds volume to a product without reacting with anything.
Register definition: “Non-reactive (chemically inert), solid ingredients that dilute other solids and/or increase the volume of cosmetic products.”
- 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.
- Leave-in conditioners 1 label First five names: 0 of 1 Leave-in conditioners without it
- Stylers 1 label First five names: 0 of 1 Stylers without it
Every label, product by product (2)
- SheaMoisture Coconut & Hibiscus Hold & Shine Moisture Mist Leave-in conditioner 13th of 25 names
- SheaMoisture Coconut & Hibiscus Frizz-Free Curl Mousse Styler 7th of 18 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.
