Abstract

Disclosed is the use of compositions containing one or more isosorbide capryiates/caprates in antiperspirants and deodorants for improving the action thereof in reducing body odor. The improvement of the action of the antiperspirants and deodorants relates especially to the intensity of reducing body odor and/or to the duration of reducing body odor.

Claims

1. A process for improving the action of an antiperspirant and/or a deodorant comprising the step of adding a composition comprising at least one isosorbide caprylate/caprate (composition A) to the antiperspirant and/or deodorant, wherein the OH number of the mixture present in the composition A of the at least one isosorbide caprylate/caprate is less than or equal to 260.

2. The process as claimed in claim 1, wherein the composition A further comprises at least one sorbitan caprylate/caprate.

3. The process as claimed in claim 1, wherein the effect of the antiperspirant and deodorant improved is the extent of the reduction in body odor.

4. The process as claimed in claim 1, wherein the effect of the antiperspirant and deodorant improved is the duration of the reduction in body odor.

5. The process as claimed in claim 1, wherein the composition A further comprises, at least one compound selected from the group consisting of caprylic acid, capric acid, sorbitol, sorbitol caprylates, sorbitol caprates, sorbitan and isosorbide;

and optionally one or more sorbitan caprylates/caprates.

6. The process as claimed in claim 2, wherein the total amount in the composition A of the at least one isosorbide caprylate/caprate and the optionally at least one sorbitan caprylate/caprate additionally present in the composition A is at least 50.0% by weight, based on the total weight of the composition A.

7. The process as claimed in claim 1, wherein the composition A comprises isosorbide monocaprylate/caprate.

8. The process as claimed in claim 7, wherein the composition A further comprises sorbitan monocaprylate/caprate alongside isosorbide monocaprylate/caprate.

9. The process as claimed in claim 7, wherein the total amount in the composition A of isosorbide monocaprylate/caprate and the sorbitan monocaprylate/caprate optionally additionally present in the composition A is at least 30.0% by weight, based on the total weight of the composition A.

10. The process as claimed in claim 8, wherein the composition A further comprises sorbitan monocaprylate/caprate alongside isosorbide monocaprylate/caprate and the weight ratio of sorbitan monocaprylate/caprate to isosorbide monocaprylate/caprate in the composition A is from 20:

1 to 1;

100.

11. The process as claimed in claim 1, wherein the amount of composition A in the antiperspirant or deodorant is from 0.1 to 20.0% by weight, based on the total weight of the antiperspirant or deodorant.

12. The process as claimed in claim 1, wherein the antiperspirant and/or deodorant comprise no aluminum-containing compounds.

13. The process as claimed in claim 1, wherein the antiperspirant and/or deodorant comprise no further substances active against body odor.

14. The process as claimed in claim 1, wherein the antiperspirant and/or deodorant further comprise at least one substance active against body odor.

15. The process as claimed in claim 14, wherein the at least one substance active against body odor is selected from the group consisting of Caprylyl Glycol, Chitosan, Ethylhexylglycerin, Glyceryl Caprylate, Glyceryl Caprylate/Caprate, Octanediol, Piroctonol, Piroctone Olamine, Silver Citrate, Silver Chloride (and) Titanium Dioxide, Silver Chloride (and) Titanium Dioxide (and) Diethyihexyl Sodium Sulfosuccinate (and) Propylene Glycol, Silver Lactate, Triclosan, Triethylcitrate and Zinc Ricinoleate.
