Abstract: The present invention relates to the use of lipoic acid, lipoic acid derivatives or salts thereof having an (R)-enantiomer-excess in cosmetic compositions for skin or hair and for the preparation of dermatological compositions for the treatment of skin disorders, to cosmetic and dermatological compositions, and to compositions in the form of commercial packs.

Abstract: A process for preparing high-purity phytantriol, that includes rectifying the phytantriol which is obtained and is contaminated with lower and/or higher boiling byproducts under medium vacuum in rectification columns containing metal cloth packings with ordered structure using channel liquid distributors with a minimum of 500 drip points/m2, which are arranged at an angle of 90° to the cloth layers of the packing elements located directly below the distributors, in which 2 or more of the packing elements underneath the liquid distributors have only a small height, which ensure absolute exclusion of air and a strictly adiabatic procedure. The preparation of high-purity phytantriol takes place particularly advantageously when the phytantriol which is contaminated with byproducts is a phytantriol which has been obtained by reacting isophytol with performic acid and subsequently hydrolyzing the product formed in the reaction with alkaline agents in a manner known per se.
