Abstract: A cosmetic or pharmaceutical composition is provided. The composition contains a mixture of oils prepared by Kolbe electrolysis of branched chain fatty acids and mixtures of branched chain fatty acids with straight chain fatty acids. The fatty acids containing from 3 to 26 carbon atoms. The oils are a mixture of oils with different spreading rates (spreading cascade).
Abstract: The invention relates to a water-free oil-based composition which is liquid at 20° C./normal pressure and which contains (a) 2 to 90% by weight of at least one linear and/or branched dialkyl carbonate and (b) 2 to 95% by weight of at least one linear and/or branched alkane containing 8 to 40 carbon atoms and to its use in the cosmetics field.
Abstract: Provided are lubricants containing a synthetic ester, one or more additional base stocks and an additive package along with methods of making and using the same. Lubricant compositions comprise a synthetic ester that is a reaction product of at least one hindered organic polyol with one or more carboxylic acid where at least some (20%) up to 100% of the acids are branched. The lubricant compositions can provide improved oxidation stability and extended service life, as compared to a lubricant whose ester component is the reaction product of one or more hindered organic polyols and one or more carboxylic acids that are all linear, in applications that involve exposure to air, moisture, and/or high temperatures. These lubricant compositions are suited to a variety of lubricant applications, including, but not limited to air compressors, gear boxes, bearing sets, hydraulic systems, and chain drives.
Abstract: Suggested is a method for enhancing energy efficiency of engines by applying to said engines a lubricant composition containing (A) carboxylic esters derived from the reaction of mono-, di- and/or poly alcohols with mono- and/or dicarboxylic acids, together with an additive blend (B) comprising at least two different additives (a) and (b) together, whereby compound (a) is selected from dithiophosphates, and compound (b) is selected from alkylated phosphorothionates, on condition that the total amount of the additive blend (B) is below 0.1 wt %, calculated on the weight of the whole composition.
