Abstract
The present invention relates to a combination of: (a) at least one particle having a wet point for oil being at least 100 ml/100 g, preferably at least 150 ml/100 g, and more preferably at least 200 ml/100 g, and a wet point for water being at least 100 ml/100 g, preferably at least 200 ml/100 g, and more preferably at least 300 ml/100 g; and (b) at least one lipophilic antioxidant agent. The present invention also relates to a method or use characterized by using the above combination. The present invention can reduce or control more effectively, preferably synergistically, the peroxidation of unsaturated lipids, preferably sebum, compared to the single use of the lipophilic antioxidant agent.
Claims15
