Abstract

Disclosed is a multi-phase personal care composition comprising an aqueous phase comprising fatty acid amide and nonionic surfactant and an oil phase, wherein the weight ratio of the nonionic surfactant to the fatty acid amide is at least 5:1, the aqueous phase is visually distinct from and in physical contact with the oil phase, and the nonionic surfactant is different from the fatty acid amide.

Claims (27)

1 . A multi-phase personal care composition comprising:

(a) an aqueous phase comprising fatty acid amide and nonionic surfactant; and

(b) an oil phase,

wherein:

(i) the nonionic surfactant to the fatty acid amide is present in a weight ratio of at least 5:1;

(ii) the aqueous phase is visually distinct from and in physical contact with the oil phase;

(iii) the non-ionic surfactant comprises the condensation products of aliphatic alcohols having from 8 to 22 carbon atoms in either straight or branched chain configuration with ethylene oxide, condensates of alkylphenols having C 6 -C 15 alkyl groups with 5 to 25 moles of ethylene oxide per mole of alkylphenol, polyoxyethylene sorbitan fatty acid esters, alkyl glucoside, or a mixture thereof; and

(iv) the nonionic surfactant is different from the fatty acid amide.

2 . The multi-phase personal care composition according to claim 1 , wherein the fatty acid amide is fatty acid alkanolamide and is present in amount of 0.0001% to 10% by weight of the total amount of the composition.

3 . The multi-phase personal care composition according to claim 2 , wherein the fatty acid amide is present in amount of 0.1% to 1% by weight of the total amount of the composition.

4 . The multi-phase personal care composition according to claim 1 , wherein the nonionic surfactant comprises alkyl glucoside, polyoxyethylene sorbitan fatty acid esters, or a mixture thereof.

5 . The multi-phase personal care composition according to claim 1 , wherein the nonionic surfactant is present in amount of 0.0001 to 15% by weight of the composition.

6 . The multi-phase personal care composition according to claim 1 , wherein the fatty acid amide to the nonionic surfactant is present in a weight ratio of 5:1 to 50:1.

7 . The multi-phase personal care composition according to claim 1 , wherein the composition comprises a retinoid.

8 . The multi-phase personal care composition according to claim 7 , wherein the retinoid is present in amount of 0.00001 to 10% weight of the total amount of the composition.

9 . The multi-phase personal care composition according to claim 1 , wherein both the aqueous phase and oil phase are transparent.

10 . The multi-phase personal care composition according to claim 1 , wherein the aqueous phase to the oil phase is present in a weight ratio of 1:8 to 8:1.

11 . A kit of parts comprising a cosmetic container, the multi-phase personal care composition according to claim 1 , and instructions for use of the kit.

12 . A method for preparing personal care product, comprising the step of shaking a cosmetic container containing the multi-phase personal care composition according to claim 1 , by human hand.

13 . The multi-phase personal care composition according to claim 2 , wherein the fatty acid amide is selected from mono- and diethanolamides of linoleic acid, palmitic acid, and coconut oil.

14 . The multi-phase personal care composition according to claim 2 , wherein the fatty acid amide comprises cocamide MEA.

15 . The multi-phase personal care composition according to claim 4 , wherein the nonionic surfactant comprises C 6 to C 20 alkyl glucoside, polyoxyethylene sorbitan C 6-24 fatty acid esters, or a mixture thereof.

16 . The multi-phase personal care composition according to claim 5 , wherein the nonionic surfactant is present in amount of 0.1 to 5% by weight of the composition.

17 . The multi-phase personal care composition according to claim 6 , wherein the fatty acid amide to the nonionic surfactant is present in a weight ratio of 5:1 to 8:1.

18 . The multi-phase personal care composition according to claim 7 , wherein the retinoid comprises retinyl palmitate, retinyl propionate, or a mixture thereof.

19 . The multi-phase personal care composition according to claim 8 , wherein the retinoid is present in amount of 0.1 to 0.6% by weight of the total amount of the composition.

20 . The multi-phase personal care composition according to claim 10 , wherein the aqueous phase to the oil phase is present in a weight ratio of 1:2 to 2:1.
