## Abstract

The subject of the invention is the use of an extract of Stevia in combination with a salt, for masking the bitterness of bitter compounds in cosmetic or dermatological compositions. This mixture of sweetener with a second gustatory agent makes it possible to mask the bitterness of the compound permanently without changing the nature of the fragrance or the colour of the composition.

## Claims

### Claim 1

A method for suppressing a bitterness of a cosmetic or dermatological composition without distorting an olfactory note thereof, said composition comprising an aqueous phase and being in a form of a product selected from the group consisting of a facial care cream, a face lotion, a face serum or fluid, a foundation, and a facial antisun product, said composition comprising a fragrance and “a hydrophilic organic ingredient with a bitter taste selected from the group consisting of xanthines, polyphenols, L-phenylalanine, urea, sucrose octaacetate, hesperidin, alpha-glucosyl hesperidin and a flavonoid that is dissolved in the aqueous phase,” said method comprising adding to the aqueous phase of the composition a combination of from 0.05 to 2 weight % of at least one steviol glucoside and from 0.01 to 0.5 weight % of a chloride salt selected from the group consisting of sodium chloride, potassium chloride, zinc chloride and mixtures thereof so as to suppress the “bitter taste” of the hydrophilic organic ingredient without distorting an olfactory note of the composition.

### Claim 2 (depends on 1)

The method of claim 1, wherein the hydrophilic organic ingredient with a bitter taste is not a hydrophilic organic UV-screening agent.

### Claim 3 (depends on 1)

“The method of claim 1”, wherein the flavonoid is selected from the group consisting of a flavanone, an isoflavone and a flavanol.

### Claim 4 (depends on 1)

The method of claim 1, wherein the amount of the steviol glucoside is from 0.1 to 1 “weight %” of the cosmetic or dermatological composition.

### Claim 5 (depends on 1)

The method of claim 1, wherein the amount of the hydrophilic organic ingredient with a bitter taste is from 0.1 to 5 “weight %” of the cosmetic or dermatological composition.

### Claim 6 (depends on 1)

The method of claim 1, wherein the steviol glucoside is selected from the group consisting of rebaudioside A and plant extracts containing rebaudioside A.

### Claim 7 (depends on 1)

The method of claim 1, wherein the steviol glucoside is an extract of Stevia.

### Claim 8 (depends on 7)

The method of claim 7, wherein the steviol glucoside is a water-soluble extract of Stevia.

### Claim 9 (depends on 1)

The method of claim 1, wherein the concentration of the chloride salt ranges from 0.01 to 0.3 “weight %” of the cosmetic or dermatological composition.

### Claim 10 (depends on 1)

The method of claim 1, wherein the concentration of the steviol glucoside ranges from 0.2 to 0.6 “weight %” of the cosmetic or dermatological composition.

### Claim 11

A method for suppressing a “bitter taste” of a cosmetic or dermatological composition without distorting an olfactory note thereof, said composition comprising an aqueous phase and being in a form of a product selected from the group consisting of a facial care cream, a face lotion, a face serum or fluid, a foundation, and a facial antisun product, said composition comprising a fragrance and a hydrophilic organic UV-screening agent with a bitter taste that is dissolved in the aqueous phase, selected from benzophenone-4, phenylbenzimidazole sulfonic acid and bis-benzotriazolyl tetramethylbutylphenol, said method comprising adding to the aqueous phase of the composition a combination of from 0.05 to 2 weight % of at least one steviol glucoside and from 0.01 to 0.5 weight % of a chloride salt selected from the group consisting of sodium chloride, potassium chloride, zinc chloride and mixtures thereof so as to suppress the bitterness of the hydrophilic organic ingredient without distorting an olfactory note of the composition.

### Claim 12 (depends on 11)

“The method of claim 11”, wherein the amount of fragrance is ranging from 0.05 to 1 “weight %” of the composition.

### Claim 13 (depends on 11)

“The method of claim 11”, wherein the amount of fragrance is ranging from 0.3 to 0.7 “weight %” of the composition.
