Abstract: Polyglycerol fatty acid ester mixtures of mono- di- and polyesters of polyglycerols having a degree of polymerization of 2 to 8 and at least one saturated and/or unsaturated fatty acid, the mixtures having an HLB of greater than 8 and containing 0 to less than 5 wt-% diglycerol fatty acid esters, 20 to 65 wt-% triglycerol fatty acid esters, 20 to 50 wt-% tetraglycerol fatty acid esters and 5 to 40 wt-% higher polyglycerol fatty acid esters, in which the fatty acid component consists of one or more fatty acids selected from the saturated and/or unsaturated, branched and/or unbranched C.sub.6 - to C.sub.14 -fatty acids containing less than 10 wt-% fatty acids having more than 14 carbon atoms; bath additive preparations containing such polyglycerol fatty acid ester mixtures; methods of using such polyglycerol fatty acid ester mixtures, and a process for preparing such mixtures.

Abstract: A process for preparing polyglycerol fatty acid ester mixtures in which a polyglycerol mixture of 0.1 to 20 wt % monoglycerol, 20 to 35 wt % diglycerol, 30 to 40 wt % triglycerol and 49.9 to 5 wt % tetra- and higher polyglycerols is reacted with one or more fatty acids, selected from the saturated C.sub.8 - to C.sub.18 -fatty acids (containing 0 to 15 wt % unsaturated fatty acids), in a molar ratio of the polyglycerol to the fatty acid component of 0.3:1.5 to 1.5:0.5 in the presence of at least one catalyst and at reduced pressure, by initially heating the reaction mixture to at least 140.degree. C. and reducing the pressure to at least 600 mbar and then heating the reaction mixture at a temperature from 140.degree. to 220.degree. C. and reducing the pressure from 600 to 10 mbar. After completion of the reaction, the resulting polyglycerol fatty acid ester mixture is cooled and optionally worked up and/or purified.

Abstract: A bath additive composition, in particular an oil bath preparation, containing at least one surface-active component, preferably a water-soluble emulsifier, at least one oily or oil-containing component selected from the natural and synthetic, mineral, ethereal and fatty animal and vegetable oils, optionally a solvent or solvent mixture and also further auxiliaries and additives, the bath additive preparation containing 10 to 60 wt-% of a polyglycerol fatty acid ester mixture as the water-soluble emulsifier and/or solubilizer, 10 to 60 wt-% of an oil, oil mixture and/or oil component having cosmetic and/or therapeutic activity and 0 to 70 wt-% of water, the polyglycerol fatty acid ester mixture containing 0 to 5 parts by weight diglycerol fatty acid esters, 20 to 65 parts by weight triglycerol fatty acid esters, 20 to 50 parts by weight tetraglycerol fatty acid esters, and 5 to 40 parts by weight higher polyglycerol fatty acid esters, for a total of 100 parts by weight, and the fatty acid component consisting

Abstract: A process for preparing a nonionic surfactant includes the steps of: cleaving at least one of the isopropylidene groups of an isopropylidene polyglycerol C.sub.6 -C.sub.22 -fatty acid or mono- or polyhydroxy fatty acid ester, by hydrolysis or ketal exchange, in the presence of acid, at a temperature in the range of about 20.degree. C. to about 100.degree. C., and at atmospheric, reduced or superatmospheric pressure, thereby regenerating hydroxyl groups on the polyglycerol; and recovering the resultant polyol ester nonionic surfactant. Such polyol ester surfactants are useful as emulsifiers, especially for preparing skin care or cosmetic formulations and paints and wood-preservation agents.

Abstract: The present invention relates to a washing agent, cleansing agent and/or toiletry containing at least one ionic and/or amphoteric surfactant and at least one C.sub.8 to C.sub.18 fatty acid monoester of diglycerol and/or C.sub.8 to C.sub.18 fatty acid diester of tetraglycerol as a constituent of the mixture, 2 to 30% by weight, perferably 10 to 20% by weight, of at least one fatty acid monoester of diglycerol and/or fatty acid diester of tetraglycerol, relative to the total surfactant content (100% by weight), being present in the surfactant mixture. The agent is employed together with certain compositions, in particular with a solvent, additives and the like. The invention also relates to the preparation of the washing agent, cleansing agent and/or toiletry and to its use as a shower preparation, bubble bath preparation, liquid hand cleanser or hair shampoo.

Abstract: A process for the preparation of fatty acid or hydroxy fatty acid esters of isopropylidene derivatives of a polyglycerol involves reacting C.sub.1 -C.sub.4 -alkyl esters of C.sub.6 -C.sub.22 -fatty acids or mono- or polyhydroxy fatty acids in alkaline medium with one or more hydroxyl-containing isopropylidene derivatives of a polyglycerol. The resultant fatty acid or hydroxy fatty acid esters of mono- and/or diisopropylidene derivatives of polyglycerol are useful as intermediates for the preparation of nonionic surfactants, as solvents or solubilizing agents and for cosmetic formulations and skin care preparations.
