Abstract
The present invention relates to compositions for application to lips. The compositions include at least about 8% by weight of a thermoplastic block copolymer comprising styrenated blocks; at least one non-polar oil and at least one polar oil having a molecular weight of less than 650 g/mol. The ratio of the concentrations by weight of the at least one non-polar oil to the concentration by weight of the at least one polar oil having a molecular weight of less than 650 g/mol is at least about 1:1.
Claims18
A composition for application to lips, comprising:
- at least about 8% by weight of a thermoplastic block copolymer comprising styrenated blocks;
- at least one non-polar oil;
- and
- at least one polar oil having a molecular weight of less than 650 g/mol, wherein the at least one non-polar oil and the at least one polar oil are present in concentrations by weight such that a ratio of the concentration by weight of the at least one non-polar oil to the concentration by weight of the at least one polar oil having a molecular weight of less than 650 g/mol is at least about 1:1, wherein the composition has a Zero Shear Viscosity at 32° C. is in a range of 15 Pa·s to 90 Pa·s, wherein the composition has a Shear-Thinning Ratio less than 5 at any temperature between 25° C. and 37° C., and wherein the composition has a High Shear Insult Viscosity Recovery of less than 30 seconds.
A method of enhancing the appearance of lips comprising applying a composition to the lips in an amount sufficient to enhance the appearance of the lips, wherein the composition comprises:
- at least about 8% by weight of a thermoplastic block copolymer comprising styrenated blocks;
- at least one non-polar oil;
- and
- at least one polar oil having a molecular weight of less than 650 g/mol, wherein the at least one non-polar oil and the at least one polar oil are present in concentrations by weight such that a ratio of the concentration by weight of the at least one non-polar oil to the concentration by weight of the at least one polar oil having a molecular weight of less than 650 g/mol is at least about 1:1, wherein the composition has a Zero Shear Viscosity at 32° C. is in a range of 15 Pa·s to 90 Pa·s, wherein the composition has a Shear-Thinning Ratio less than 5 at any temperature between 25° C. and 37° C., and wherein the composition has a High Shear Insult Viscosity Recovery of less than 30 seconds.
