Abstract
Processes for obtaining aqueous dispersions comprising alcohols and acids obtained by hydrolysis of jojoba oil. Hydrolyzed jojoba oil products are treated by a process comprising neutralization of jojoba fatty acids with aliphatic organic amines dissolved in a co-solvent followed by the dispersion of both the neutralized fatty acids together with jojoba alcohols in an aqueous medium. The products obtained, generically named hydrolyzed jojoba oil (HJO), promote transdermal absorption and are useful vehicles for carrying a wide range of pharmaceutical and cosmetic compositions, including pharmaceutical and cosmetic compositions comprising either lipophilic or hydrophilic active principles. The HJO can also be used to produce a semisolid, self-emulsified jojoba oil (SEJO), obtained by emulsifying the HJO in jojoba oil.
