Cosmetic composition

Claim 2

A cosmetic composition for topical application to human skin or hair consisting essentially of a blend of at least two polyol fatty acid polyesters, wherein a first polyol fatty acid polyester has a Melting Value of from -30° C. to +30° C. and a second polyol fatty acid polyester has a Melting Value of from +30° C. to +70° C., provided that the difference between the respective Melting Values is at least 5° C., the polyesters being formed from esterification between a polyol and at least 1 fatty acid, the polyol having at least 4 free hydroxyl groups, at least 60% of the hydroxyl groups being esterified, the fatty acids having from 8 to 22 carbon atoms, the composition having a Melting Value of from 20° C. to 60° C., as determined by the Melting Value Test.

Claim 3

The composition according to claim 1, wherein the difference between the respective Melting Values of the first and second polyol fatty acid polyesters is at least 10° C.

Claim 4

The composition according to claim 1, wherein at least one of the polyol fatty acid polyesters has an Occlusivity Value of at least 45%, as measured by the Occlusivity Value Test.

Claim 5

The composition according to claim 1, wherein at least one of the polyol fatty acid polyesters is derived from a sugar polyol.

Claim 6

The composition according to claim 1, wherein the fatty acid moiety of the polyol fatty acid polyester is derived from one or more oils or one or more fats.

Claim 7

The composition according to claim 1, which has a Melting Value of from 25° C. to 55° C.

Claim 8

The composition according to claim 1, which has a Consistency Value of from 10 to 350, as measured by Consistency Value Test.

Claim 9

The composition according to claim 1, which has an Occlusivity Value of at least 40%, as measured by the Occlusivity Value Test.

Claim 10

A method of treating human skin, hair or nails to provide thereon an occlusive layer which comprises the steps of applying topically an effective amount of the composition according to claim 1.

Claim 11

A cosmetic composition for topical application to human skin or hair consisting essentially of a blend of at least two polyol fatty acid polyesters, a first polyol fatty acid polyester having a melting value of from -30° C. to +30° C., the polyester being formed by esterification between a polyol and at least one fatty acid derived from a source oil selected from the group consisting of soybean oil, coconut oil and fish oil; a second polyol fatty acid polyester having a melting value of from +30° C. to 70° C., the polyester being formed by esterification between a polyol and at least one fatty acid derived from a source oil selected from the group consisting of palm oil, palm kernel oil and soybean oil, the polyol having at least 4 free hydroxyl groups at least 60% of which are esterified, and the difference between the respective melting values of the polyesters being at least 5° C., and wherein the composition has a Melting Value of from 20° C. to 60° C. as determined by the Melting Value Test.

Claim 12

A cosmetic composition for topical application to human skin or hair consisting essentially of a blend of at least two polyol fatty acid polyesters, a first polyol fatty acid polyester having a melting value of from -30° C. to +30° C., the polyester being formed by esterification between a polyol and at least one fatty acid derived from a source oil selected from the group consisting of soybean oil, coconut oil and fish oil; a second polyol fatty acid polyester having a melting value of from +30° C. to 70° C., the polyester being formed by esterification between a polyol and at least one fatty acid derived from a source oil selected from the group consisting of palm oil, palm kernel oil and soybean oil, the polyol having at least 4 free hydroxyl groups at least 60% of which are esterified, and the difference between the respective melting values of the polyesters being at least 5° C., and wherein the composition has a Melting Value of from 20° C. to 60° C. as determined by the Melting Value Test.

Claim 13

The composition according to claim 10 wherein the first and second polyol fatty acid polyesters are formed by esterification with fatty acids derived from different source oils.
