An oil and water gel composition is provided containing a polymer gel former of a polymer or copolymer of acrylic acid or acrylamide, a wax component having a melting point of at least 30&#xb0; C. containing esters of pentaerythritol, dipentaerythritol and/or tripentaerythritol, and an oil component liquid at 25&#xb0; C. and water.

O/W-gel-compositions having pentaerythritol esters or oligomers thereof

The invention relates to a water-free oil-based composition which is liquid at 20&#xb0; C./normal pressure and which contains

Emollient mixture for cosmetic and pharmaceutical formulations

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

A composition for cosmetic compositions which contains (a) at least one dicarboxylic acid diester of a C6-C13 dicarboxylic acid with a C12-22 fatty alcohol; (b) at least one oil component. The composition provides excellent antiperspirant and deodorant sticks when combined with an antiperspirant or deodorizing composition. Addition of a pigment provides cosmetic sticks such as lipsticks. The composition can be water free.

Antiperspirant composition based on dicarboxylic acid diesters of a C6-C18 dicarboxylic acid with C12-C22 fatty alcohols

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

The invention relates to new self-emulsifying preparations containing

Self-emulsifying preparations

An emulsifier composition including an ester selected from the group consisting of: pentaerythritol, dipentaerythritol, tripentaerythritol, and mixtures thereof; at least one alkoxylated nonionic emulsifier; and less than 10% by weight water, where partial glycerides may be present in an amount of less than 10% by weight, based on the amount of component (a) present in the composition, is provided. A process for the production of an emulsion, including dispersing the emulsifier composition in an oil phase; heating the emulsifier composition dispersed in the oil phase to a temperature above the phase inversion temperature thereof; heating an aqueous phase to a temperature above the phase inversion temperature thereof; and stirring the oil phase with the aqueous phase and cooling to room temperature is also provided. A cosmetic composition including the emulsifier composition is also provided.

Emulsifier composition based on pentaerythritol esters and alkoxylated nonionic emulsifiers

Emulsions suitable for use in cosmetic and pharmaceutical compositions are disclosed. Various substrates for body care, such as wipes and pads, are disclosed, which substrates are impregnated with the emulsions. Such treated substrates are suitable for use, for example, in body care, sun protection, antiperspirant and insect repellent formulations. A process for cold temperature production of the emulsions is also disclosed.
