What it is
In the register’s words: “Cetearamidoethyldiethonium Succinoyl Hydrolyzed Pea Protein is the quaternary ammonium salt formed by the reaction of cetearamidoethyl diethylamine and succinoyl hydrolyzed pea protein.”
- EU register name (INCI)
- CETEARAMIDOETHYLDIETHONIUM SUCCINOYL HYDROLYZED PEA PROTEIN
What the register lists it for
These are the uses the European Commission’s CosIng register lists for Cetearamidoethyldiethonium Succinoyl Hydrolyzed Pea Protein 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.
- Antistatic
-
Cuts the static that makes dry hair fly away. Many conditioning ingredients carry this role too, because both work at the hair’s surface.
Register definition: “Preventing and/or reducing static electricity by neutralising electrical charge on surfaces.”
- Cleansing
-
The register’s general role for ingredients that help clean, from washing ingredients to some plant extracts.
Register definition: “Helping to keep the body surface clean.”
- 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.

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.
