## Abstract

A cosmetic method of reducing perspiration comprising the topical application of a composition comprising a non-pore blocking antiperspirant agent of general formula (I): Ar—CHaCHa—X wherein Ar is an aryl group, a is 1 or 2, and X is a sub-structure of formula CH(OH)—Y or CO.Z, wherein Y is a C1-C10 hydroxyalkyl group and Z is a C1-C10 hydroxyalkyl group or a C1-C10 oxyalkyl group.

## Claims

### Claim 1

A cosmetic method of reducing perspiration comprising the topical application of a composition comprising a non-pore blocking antiperspirant agent of general formula I:
Ar—CHaCHa—X
wherein Ar is an aryl group, a is 1 or 2, and X is, a sub-structure of formula CH(OH)—Y or CO.Z, wherein 1 is a C1-C10 hydroxyalkyl group and Z is a C1-C10 hydroxyalkyl group or a C1-C10 oxyalkyl group.

### Claim 2 (depends on 1)

A cosmetic method according, to claim 1, wherein the non-pore blocking antiperspirant agent of general formula I has an aryl group such that pare to the X group and at solely one position meta to the X group, the aryl group is non-substituted or has a substituent selected from OH or OCH3 and at all other, positions the aryl group is non-substituted.

### Claim 3 (depends on 1)

A cosmetic method according to claim 1, wherein X in general formula I is as a sub-structure of formula CH(OH)—Y′ or CO.Z, wherein Y′ is of formula CH2CH(OH)R, wherein R is a C1-C6 alkyl group (preferably a C5 linear, unbranched alkyl group), and Z is as defined in claim 1.

### Claim 4 (depends on 1)

A cosmetic method according to any claim 1, wherein X in general formula I is a sub-structure of formula CH(OH)—Y or CO.Z′, wherein Y is as defined in claim 1 and Z′ is of formula CH2CH(OH)R, wherein R is a C1-C6 alkyl group (preferably a C5 linear unbranched alkyl group) or is a C1-C4 oxyalkyl group.

### Claim 5 (depends on 1)

A cosmetic method according to claim 1, wherein the non-pore blocking antiperspirant agent is selected from 6-gingerol, 6-gingerdiol, or ethyl cinnamate.

### Claim 6 (depends on 5)

A cosmetic method according to claim 5, wherein the non-pore blocking antiperspirant agent is selected from 6-gingerol or 6-gingerdiol.

### Claim 7 (depends on 1)

A cosmetic method according to claim 1, wherein a conventional astringent aluminium-containing antiperspirant salt is not also applied.

### Claim 8 (depends on 1)

A non-pore blocking antiperspirant agent as described in claim 1 for use as a treatment for perspiration in particular excessive perspiration.

### Claim 9

An antiperspirant composition comprising a non-pore blocking antiperspirant agent selected from 6-gingerol, 6-gingerdiol or C1-C4 alkyl cinnamate and a carrier fluid comprising a C2-C6 vicinal diol.

### Claim 10 (depends on 9)

A composition according to claim 9, wherein the non-pore blocking antiperspirant agent comprises from 0.2 to 10% of the composition, the carrier fluid comprises from 10 to 99% of the composition, and the C2-C6 vicinal dial from 2 to 40% of the composition, all percentages being by weight.

### Claim 11 (depends on 9)

A composition according to claim 9, comprising a C2-C4 vicinal diol.

### Claim 12 (depends on 9)

A composition according to claim 9, wherein the carrier fluid comprises water and ethanol.

### Claim 13 (depends on 9)

A composition according to claim 9, comprising a thickening agent, preferably a hydroxyalkyl cellulose thickening agent.

### Claim 14 (depends on 9)

A composition according to claim 9, wherein the non-pore blocking antiperspirant agent selected from 6-gingerol or 6-gingerdiol.

### Claim 15 (depends on 9)

A product comprising a composition according to claim 9 and dispenser for said composition, the dispenser comprising containment means and application means for the composition.

### Claim 16 (depends on 15)

A product according to claim 15, wherein the dispenser is able to function without the consumer needing to touch the composition with his or her hands in order for it to be applied.
