Peg-40 Hydrogenated Castor Oil is derived from castor oil and polyethylene glycol (PEG). It is used as a emollient and emulsifier.

This ingredient may or may not be vegan, depending on the source.

The term 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.

However, their products may still contain ingredients such as essential oils that are considered a fragrance.
