Abstract: The present invention relates to a process for the efficient, sustainable and gentle preparation of bio-based alkanediols, especially 1,2-alkanediols, at moderate temperatures based on a recycling of side products and non-reacted educts. The present invention also relates to a composition comprising at least two alkanediols obtainable by said process and to the use of said composition in consumer product formulations. In addition, the present invention relates to consumer products as such comprising the inventive composition.

Abstract: The present invention relates to a cosmetic or pharmaceutical composition comprising an effective amount of at least one linear 1,2-alkanediol having a carbon chain of 5 to 13 carbon atoms and an effective amount of at least one linear 2,3-alkanediol having a carbon chain of 5 to 13 carbon atoms. Moreover, the present invention relates to a composition comprising an effective amount of at least one linear 1,2-alkanediol having a carbon chain of 5 to 13 carbon atoms and an effective amount of at least one linear 2,3-alkanediol having a carbon chain of 5 to 13 carbon atoms. Additionally, the present invention relates to the use of the compositions of the present invention for enhancing the antioxidative effect of an antioxidant, for improving the sensory properties, i.e. skin sensation, of a liquid lipophilic component, for sebum control, or for malodour management, or for modulating fragrance notes, or for modification of fragrance notes, or for suppression of fragrance notes, or for topical applications, or for coverage of the malodour of 1-octen-3-ol, or for masking insect alluring odours, or for repelling insects. Finally, the present invention relates to a cosmetic product, a pharmaceutical or a homecare product comprising a composition according to the present invention.
