What the register lists it for
These are the uses the European Commission’s CosIng register lists for Sodium Lauroyl Lactylate 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.”
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 3 labels First five names: 2 of 3 Shampoos without 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.
