An ethoxylated hydrogenated castor oil used as an emulsifier.
What it is
PEG-7 hydrogenated castor oil is hydrogenated castor oil reacted with ethylene oxide, with an average of 7 ethylene oxide units. With this low degree of ethoxylation it is oil-soluble and is typically used in water-in-oil emulsions. CosIng lists it as an emulsifying and cleansing surfactant.
Where it is used
Found in rich creams, balms, sunscreens and other water-in-oil emulsions.
Limits of interpretation
The INCI list shows which ingredients are present, not how much of each. Above 1%, ingredients are listed in descending order of weight; below 1% the order is free.
The number 7 refers to the average degree of ethoxylation, so the raw material is a mixture of molecules.
Functions
- Surfactant – emulsifying
- Helping suspensions or dispersions of liquids in a second liquid by reducing the surface tension of the substances to be emulsified.
- Surfactant – cleansing
- Wetting body surfaces, emulsifying or solubilizing oils, and suspending soil (generally, such ingredients contribute to the foaming and lathering properties of cleansing products).
EU regulation
This ingredient is not listed in the annexes of Regulation (EC) No 1223/2009 in the CosIng data.
