Abstract

The use of one or more compounds of the formula (I)

in which
R is a straight-chain or branched saturated alkyl group having 5 to 11 carbon atoms or a straight-chain or branched mono- or polyunsaturated alkenyl group having 5 to 11 carbon atoms

as thickeners is described.

The use is preferably in cosmetic, dermatological or pharmaceutical compositions, in crop protection formulations, in washing or cleaning compositions or in paints or coatings.

First claim

The invention claimed is:

1. A method of thickening cosmetic, dermatological or pharmaceutical compositions, in crop protection formulations, in washing or cleaning compositions or in paints or coatings, said method comprising adding a thickener composition comprising one or more compounds of the formula (I)

in which
R is a straight-chain or branched saturated alkyl group having 5 to 11 carbon atoms or a straight-chain or branched mono- or polyunsaturated alkenyl group having 5 to 11 carbon atoms, and
one or more other substances selected from the group consisting of sorbitol, sorbitol esters, isosorbide and isosorbide monoesters, and wherein the hydroxyl value (as mg KOH/g) of the thickener composition is smaller than or equal to 250 and additionally
from 0.001 to 0.2 part by weight of the one or more isosorbide monoesters of the formula (II)

and up to 0.1 part by weight of carboxylic acid RCOOH, wherein R has the meaning given above for formula (I),
in each case based on 1.0 part by weight of the one or more compounds of the formula (I).

2. The method of claim 1 , wherein the radical R in formula (I) is a straight-chain saturated alkyl radical having 7 to 9 carbon atoms.

3. The method of claim 2 , wherein the radical R in formula (I) is a straight-chain saturated alkyl radical having 7 carbon atoms.

4. The method of claim 1 , wherein the composition comprises one or more compounds of the formula (I) and one or more sorbitan esters of sorbitan and carboxylic acids R a COOH, where R a is a straight-chain or branched saturated alkyl chain having 5 to 11 carbon atoms or a straight-chain or branched mono- or polyunsaturated alkenyl group having 5 to 11 carbon atoms, and the weight ratio of the one or more compounds of the formula (I) to the one or more sorbitan esters just mentioned is from 70:30 to 100:0.

5. The method of claim 4 , wherein the one or more sorbitan esters of sorbitan and carboxylic acids RaCOOH are selected from sorbitan esters of sorbitan and caprylic acid.

6. The method of claim 1 , wherein the composition comprises the one or more compounds of the formula (I) in amounts of at least 50% by weight, in each case based on the total weight of the finished composition.

7. The method of claim 1 , wherein the cosmetic, dermatological or pharmaceutical compositions, the crop protection formulations, the washing or cleaning compositions or the paints or coatings comprise the one or more compounds of the formula (I) in amounts of from 0.01 to 10.0% by weight, in each case based on the total weight of the finished cosmetic, dermatological or pharmaceutical compositions, crop protection formulations, washing or cleaning compositions or paints or coatings.

8. The method of claim 1 , wherein the cosmetic, dermatological or pharmaceutical compositions, the crop protection formulations, the washing or cleaning compositions or the paints or coatings are formulated on an aqueous or aqueous-alcoholic basis or are present as emulsion or dispersion.

9. The method of claim 1 , wherein the cosmetic, dermatological or pharmaceutical compositions, the crop protection formulations, the washing or cleaning compositions or the paints or coatings have a pH of from 2 to 11.
