What the register lists it for
These are the uses the European Commission’s CosIng register lists for Macadamia Ternifolia Seed Oil 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.
- Emollient
-
Oils, butters and similar ingredients that make a surface feel soft and smooth. On hair they coat the strand; many plant oils carry this role.
Register definition: “Acting as lubricants on the skin surface providing the skin with a soft and smooth appearance.”
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.
