摘要:
Disclosed are novel polyglycerine polyricinoleates as emulsifiers obtained by the esterification of polyricinoleic acid with a natural condensation rate of from 2 to 10 with a polyglycerine mixture comprising 5-35 wt. % glycerine, 15-40 wt. % diglycerines, 10-30 wt. % triglycerines, 8-20 wt. % tetraglycerines, and 3-10 wt. % pentaglycerines, and the remainder being oligoglycerines. The materials have improved emulsifying capacity.
摘要:
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.
摘要:
The invention relates to alkyl benzoate mixtures, the sum of the C12- and C14-alkyl benzoates being greater than or equal to 85%, in relation to the total sum of the alkyl benzoates. The invention also relates to the use of said alkyl benzoate mixtures in cosmetic and/or pharmaceutical preparations, in particular as oil components.
