Abstract
The present invention relates to raspberry seed oil derivatives derived by the reaction of a guerbet alcohol and cold pressed raspberry seed oil. The choice of cold pressed raspberry seed oil as a raw material in the preparation of the compounds of the present invention is critical, since it has been found that the cold pressed raspberry seed oil contains antioxidants, antimicrobial compounds and which when reacted with a guerbet alcohol result in products that deliver said actives to the skin and hair, resulting in protection of the skin and hair from environmental factors such as acid rain, ozone attack and UV degradation.
