Description

Field of the invention

The The invention relates to esters and their use in cosmetic and / or pharmaceutical preparations and process for their preparation.

State of the art

in the Range of cosmetic emulsions for skin and hair care consumers make a variety of demands: Aside from the cleansing and nourishing effects that the application purpose determine value is as different parameters as possible dermatological compatibility, good moisturizing Characteristics, elegant appearance, optimal sensory Impression and storage stability.

preparations to clean and care for human skin and hair Usually used in addition to a number of Surface-active substances, especially oil bodies and water. For example, oil bodies / emollients Hydrocarbons, ester oils and vegetable and animal oils / fats / waxes used. To meet the high demands of the market sensory properties and optimal dermatological compatibility To be fulfilled, new oil bodies and continuously Emulsifier mixtures developed and tested. The use of ester oils in cosmetics has long been known. Because of their importance also continuously developed new processes for their production.

The object of the present invention was to provide novel, preferably liquid at 20 ° C ester oils for cosmetic and / or pharmaceutical applications available with respect to the sensory properties (lightness, "non-greasy skin feel", softness, Spreitvermögen, absorption, dispersibility , Oiliness) have an improved profile and can be incorporated into a variety of cosmetic and / or pharmaceutical formulations. The hydrolytic stability of the esters and the low-pH formability of the esters were also of interest here. Furthermore, the esters should be workable in both W / O and O / W formulations. Furthermore, the esters should be particularly compatible with crystalline UV filters, pigments, antiperspirant salts and silicones. Furthermore, the esters should be stable to oxidation. Furthermore, in particular for preparations of decorative cosmetics (for example make-up), the so-called "non-transfer" property is of interest. In addition, the compatibility of the esters with preparations containing detergent substances (such as shower baths, shampoos, hair conditioners) is of interest. It was also of particular interest to provide substances which can completely or partially replace silicone oil in cosmetic and / or pharmaceutical preparations. The silicone oils used in the prior art are disadvantageous, inter alia, because of their bioaccumulation. It was also of special interest to provide substances which have a low irritation potential (including skin and eyes). WO 2006/097235 describes esters of 2-propylheptanol with linear or branched carboxylic acids. WO 2006/097235 describes the ester of 2-propylheptanol with 2-propylheptanoic acid. The object of the present invention was to provide improved over the prior art esters. It has been found that the esters of the present invention accomplish this task.

These are mixtures of homologs whose mean Alkoxylierungsgrad the ratio of the amounts of ethylene oxide and / or propylene oxide and substrate, with which the addition reaction is carried out corresponds. Depending on the degree of ethoxylation, these are W / O or O / W emulsifiers. C _12/18 fatty acid monoesters and diesters of addition products of ethylene oxide onto glycerol are known as refatting agents for cosmetic preparations.

According to the invention particularly useful and mild emulsifiers are polyol poly-12-hydroxystearates and mixtures thereof which, for example, under the trademarks "Dehymuls ^® PGPH" (W / O-emulsifier) or "Eumulgin ^® VL 75" (mixture with Coco Glucosides in a weight ratio of 1: 1, O / W emulsifier) or Dehymuls® ^® SBL (W / O emulsifier) are marketed by Cognis Germany GmbH. In this context, reference should be made in particular to the European patent EP 766 661 B1 directed. The polyol component of these emulsifiers can be derived from substances which have at least two, preferably from 3 to 12 and in particular from 3 to 8 hydroxyl groups and from 2 to 12 carbon atoms.

As lipophilic W / O emulsifiers are in principle suitable emulsifiers with an HLB value of 1 to 8, which are summarized in numerous tables and known in the art. Some of these emulsifiers are for example in Kirk-Othmer, "Encyclopedia of Chemical Technology", 3rd Ed., 1979, Vol. 8, page 913 , listed. For ethoxylated products, the HLB value can also be calculated according to the following formula: HLB = (100-L): 5, where L is the weight fraction of the lipophilic groups, ie the fatty alkyl or fatty acyl groups in weight percent, in the ethylene oxide adducts.
