Dialkyl carbonates of branched alcohols and their use

The invention relates to a hydrocarbon mixture that contains at least two hydrocarbons that are different from each other, the number of carbons thereof differing by more than one, wherein said two hydrocarbons that differ from each other make up at least 60% by weight, preferably at least 70% by weight of the total of the hydrocarbons. The invention also relates to the use of said hydrocarbon mixtures and to cosmetic and/or pharmaceutical preparations containing said hydrocarbon mixtures.

Hydrocarbon mixtures and use thereof

Disclosed is a method of reducing or avoiding staining in or on clothing caused by a cosmetic or dermatological preparation comprising one or more antiperspirant substances and/or of improving the ability of stains in or on clothing which are caused at least in part by said preparation to be washed out from the clothing. The method comprises including in the preparation one or more cationic surfactants.

Use of charged surfactants for reducing textile staining by antiperspirants

Disclosed is cosmetic or dermatological preparation which comprises one or more antiperspirant substances and one or more cationic surfactants.

Disclosed is cosmetic or dermatological preparation which is present as an aerosol spray and comprises one or more antiperspirant substances and one or more cationic surfactants.

The present invention relates to an emulsion concentrate containing water-insoluble oil components (A), hydrophilic non-ionic emulsifiers (B), lipophilic co-emulsifiers (C), polyols (D) and water; which comprises less than 50% by weight of water-insoluble oil component (A), based on the total weight of the concentrate, and comprises components (A), (B) and (C) and (D) in a ratio by weight A:B:C:D=1:(0.25-0.6):(0.25-0.6):(0.45-0.65). The invention further relates to the use of these emulsion concentrates, and also to preparations and paper products, non-woven products or textile products for body care and personal cleansing, which comprise water-insoluble oil components (A), hydrophilic non-ionic emulsifiers (B), lipophilic co-emulsifiers (C), and polyols (D) in a ratio by weight A:B:C:D=1:(0.25-0.6):(0.25-0.6):(0.45-0.65).

Emulsion concentrate

The present invention relates to a process for preparing esters from fatty alcohols, in which fatty alcohols and fatty acids are reacted in the presence of an enzyme at a temperature in the range of 30 to 50&#xb0; C., the water which forms is removed and the reaction is completed under reduced pressure at a temperature of 50 to 80&#xb0; C.

Ester synthesis

Mixtures of Guerbet alcohols, their use in cosmetic and/or pharmaceutical preparations, and also cosmetic and/or pharmaceutical preparations comprising mixtures of Guerbet alcohols are described. Of suitability as petroleum jelly substitute are in particular Guerbet alcohol mixtures with a melting range, measured by differential scanning calorimetry (DSC), between &#x2212;20&#xb0; C. and +70&#xb0; C., where the width of the melting range comprises at least 30 temperature degrees and the maximum of the melting range is 35&#xb1;10&#xb0; C. These are obtainable for example by reacting

Guerbet alcohol mixtures and uses thereof

Described are compositions, containing a. compounds selected from (i.) hydrogenated and/or non-hydrogenated, ethoxylated and/or propoxylated triglycerides of ricinoleic acid having degree of ethoxylation and/or propoxylation of &#x2267;20, (ii.) addition products of 2-50 mol ethylene oxide on sorbitan monoesters and/or diesters of saturated or unsaturated fatty acids having 6-22 carbon atoms, and (iii.) addition products of 2-50 mol ethylene oxide and 1-20 mol propylene oxide on alpha olefin epoxides having 8-22 carbon atoms and ring-opened with polyols, b. ethoxylated and/or propoxylated glycerol fatty acid monoester and/or diester having degree of ethoxylation of &#x3c;20, c. polyol selected from glycerol, diglycerol, trigylcerol, tetraglycerol, alkylene glycols and polyalkylene glycols, d. glycerol fatty acid monoester of general formula (I), where Ris saturated or unsaturated, branched or linear group having 9-19 carbon atoms, and e. &#x2266;20 wt % water. Further described is use of said compositions, and substrates treated with the composition.
