The present invention is in the field of antioxidants and relates to cosmetic or pharmaceutical, preferably dermatological, compositions or homecare product comprising or consisting of a synergistic combination of a specific antioxidant and an effective amount of 1,2-heptanediol and/or 2,3-heptanediol or of a specific alkanediol or a mixture of two or more different specific alkanediols and the use of said compositions as a cosmetic, for personal care, as a pharmaceutical or homecare product, in particular for scavenging reactive oxygen species (ROS), for inhibition matrix metalloproteinases expression and/or for inhibiting interleukin 8 (IL-8) secretion. Additionally, the present invention relates to the use of 1,2-heptanediol and/or 2,3-heptanediol or of a specific alkanediol or a mixture of two or more different specific alkanediols for enhancing the antioxidative effect of an antioxidant in a cosmetic or pharmaceutical, preferably dermatological, composition or homecare product, and/or for enhancing the antioxidative effect of a cosmetic or pharmaceutical, preferably dermatological, composition upon application.

Compositions comprising one or more (bio)-alkanediols with antioxidants

The present invention primarily relates to a fatty acid ester or mixture of two or more fatty acid esters or mixture comprising one or more fatty acid esters, wherein the fatty acid ester or one, two, three or more, preferably all, of the fatty acid ester(s) is/are selected from the group consisting of 3-hydroxypropyl caprylate, glyceryl monocaprylate, 3-hydroxypropyl undecylenate and glyceryl monoundecylenate, for use in the treatment of an excess ofon the skin surface of mammals, preferably of humans. The present invention further relates to particular mixtures or products, and to the cosmetic, non-therapeutic use of fatty acid esters or of mixtures or products comprising fatty acid esters as defined herein to reduce the amount ofon the skin surface of mammals, preferably of humans.

Fatty acid esters as anti-agents

The invention relates to a method for producing limonene comprising or consisting of the following steps: (a) providing beta-pinene or a beta-pinene containing starting material: (b) admixing the starting material with a catalytically effective amount of a MWW-type zeolite: (C) heating the reaction mixture to a temperature in the range of between 60 and 100° C.; and optionally (d) separating the limonene or a limonene-enriched fraction from the sump.

Method for producing limonene and composition containing limonene

What is proposed is a continuous process for producing limonene which has the feature that beta-pinene or beta-pinene-containing starting materials are isomerized in a trickle-bed reactor in the presence of acid catalysts.
