The disclosure relates to dialkyl carbonates of branched alcohols and their use in cosmetic and/or pharmaceutical compositions. The disclosure more particularly relates to dialkyl carbonates in which the alkyl groups are both 2-propyl-1-heptyl groups.

Dialkyl carbonates of branched alcohols and their use

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.

A deodorizing composition containing: (a) from about 10 to 30% by weight of a dialkyl carbonate corresponding to formula I: wherein Ris a linear alkyl and/or alkenyl group containing from about 6 to 22 carbon atoms, a 2-ethylhexyl, an isotridecyl, an isostearyl group or a group derived from a polyol containing 2 to 15 carbon atoms and at least two hydroxyl groups; Rhas the same meaning as Ror is an alkyl group containing from about 1 to 5 carbon atoms; and n and m, independently of one another, represent a number up to 100, and (b) an antiperspirant.

Deodorizing preparations

The disclosed invention relates to a cosmetic composition containing at least one branched oligo-&#x3b1;-olefin, characterized in that the side chains at one branch point at least are ethyl, propyl or longer branched alkyl chains, the branched oligo-&#x3b1;-olefin being obtainable by oligomerization of

Cosmetic oligo-&#x3b1;-olefin containing compound

A smooth, dry-feeling, less-greasy, substantially-odorless, ecotoxicologically-safe, wax-based composition with a melting point above 25&#xb0; C., comprising one or more wax components selected from dialkyl carbonates, dialkylene carbonates, and mixtures of two or more thereof; less than 10%, by weight, of water; and (c) optionally, one or more components selected from the group consisting of one or more wax or oil components selected from the group consisting of dialkyl ethers, dialkylene ethers, dicarboxylic acids, hydroxyfatty alcohols, and mixtures of two or more thereof, as well as one or more wax-like lipid components, other than those in previously listed, one or more other oil components, liquid at 20&#xb0; C. and immiscible with water at 25&#xb0; C., other than those previously listed, one or more emulsifiers, one or more zwitterionic, amphoteric, cationic or anionic surfactants, one or more other auxiliaries and/or additives, and one or more physiologically-active components, which compositions are useful in a cosmetic, personal hygiene and/or body-care preparation.

Smooth-feeling wax-based compositions for personal care preparations

The invention comprises the use of one or more charged surfactants in preparations having an antiperspirant effect for reducing staining in or on clothing and improving improvement the ability of stains to be washed out of the clothing.

The invention relates to a glycerol ether mixture which consists essentially of a) at least one Cglycerol monoalkyl ether, b) at least one Cglycerol dialkylether and optionally c) at least one Cglycerol trialkyl ether and/or d) at least one Cfatty alcohol, components a) and b) together making up at least 50% by weight of the glycerol ether mixture and the ratio by weight of component a) to component b) being in the range from 3:1 to 1:2. The invention also relates to a process for producing the glycerol ether mixture and to cosmetic compositions containing the glycerol ether mixture.

Glycerol ether mixture, cosmetic composition containing this mixture and process for its production

A fatty acid ester of pentaerythritol, a pentaerythritol oligomer, or mixtures thereof, where the fatty acid has 6 to 22 carbon atoms, and the ester contains less than 0.3% by weight Cfatty acid acyl groups and has a melting point of at least 30&#xb0; C. is provided. A process for the production of a C/Cfatty acid pentaerythritol ester including (A) providing about 1.8 to about 2.2 mol of a fatty acid mixture per mol of pentaerythritol; (B) esterifying component (A) at temperatures ranging from about 180&#xb0; C. to about 250&#xb0; C. in an inert gas atmosphere in the absence of solvent to form a reaction mixture; (C) stirring the reaction mixture in vacuo until it has an acid value of less than 1 and an OH value of 145 to 158 is provided. A cosmetic and/or pharmaceutical composition including the above-described ester is also provided.

Fatty acid esters, processes for their production and for incorporation into cosmetic and/or pharmaceutical formulations

A composition comprising: (a) from about 0.1 to 60%, by weight, of one or more fatty alcohols; (b) from about 30 to 97%, by weight, of one or more ethoxylated fatty alcohols; (c) from about 0.1 to 20%, by weight, of a component selected from the group consisting of a dialkyl ether, a dialkenyl ether, and mixtures thereof; and (d) less than 5%, by weight, of water, all weights being based on the weight of the composition, which composition is useful as an emulsifier for cosmetic and pharmaceutical compositions, particularly for forming low-viscosity oil-in-water emulsions.

Emulsifier mixture containing fatty alcohols, ethoxylated fatty alcohols and oil and wax components

Lanolin-free lanolin substitute compositions comprising:

Vegetable substitute for lanolin

An emulsifier for use in making PIT or microemulsions is comprised of (a) from 45 to 60% by weight of a partial glyceride, (b) from 5 to 25% by weight of an alcohol polyglycol ether, (C) from 5 to 15% by weight fatty alcohol, and (d) from 0 to 15% by weight of a wax ester wherein the monoglyceride content of the partial glyceride is less than 50% by weight and wherein the monoglyceride is comprised of palmitic and stearic acid residues in a ratio by weight of from 40:60 to 60:40.
