What it is
In the register’s words: “Fatty acids, coconut, reaction products with ethanolamine, propoxylated (2 mol PO average molar ratio).”
- EU register name (INCI)
- PPG-2 HYDROXYETHYL COCAMIDE
What the register lists it for
These are the uses the European Commission’s CosIng register lists for PPG-2 Hydroxyethyl Cocamide 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.
- 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).”
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: 1 of 1 Shampoos without it
- Clarifying shampoos 2 labels First five names: 0 of 2 Clarifying shampoos without it
Every label, product by product (3)
- Not Your Mother's Curl Talk Clean Slate Daily Shampoo Shampoo 5th of 22 names
- Aunt Jackie's Power Wash Intense Moisture Clarifying Shampoo Clarifying shampoo 12th of 30 names
- Maui Moisture Scalp Care Clarifying Shampoo with Apple Cider Vinegar Clarifying shampoo 29th of 34 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.
