Abstract

Provided are water-resistant and/or photoprotective compositions including: (a) an aqueous phase including from 0% to 99.9% by weight of the composition, based on the total weight of the composition; (b) an oil phase including from 0% to 99.9% by weight of the composition, based on the total weight of the composition; (c) an active sun block agent; and (d) a micronized, non-solubilized wax including 0.1% to 10% by weight of the composition, based on the total weight of the composition; wherein the wax has a D50 particle size of 1 to 100 μm, and a melting point of at least 70° C.; and wherein the composition includes at least 50% by weight of at least one of the aqueous phase or the oil phase. Uses of the compositions, and methods utilizing the compositions, are also provided.

First claim

1 . A water-resistant and/or photoprotective composition comprising:
a. an aqueous phase comprising from 0% to 99.9% by weight of the composition, based on the total weight of the composition; b. an oil phase comprising from 0% to 99.9% by weight of the composition, based on the total weight of the composition; c. an active sun block agent; and d. a micronized, non-solubilized wax comprising 0.1% to 10% by weight of the composition, based on the total weight of the composition; wherein the wax has a D50 particle size of 1 to 100 μm, and a melting point of at least 70° C.; and wherein the composition comprises at least 50% by weight of at least one of the aqueous phase or the oil phase.

2 . The composition of claim 1 , wherein the wax has a D50 particle size of 1 to 50 μm.

3 . The composition of claim 1 , wherein the wax has a melting point of 70 to 100° C.

4 . The composition of claim 1 , wherein the wax comprises 1% to 5% of the composition, based on the total weight of the composition.

5 . The composition of claim 1 , wherein the composition further comprises a stabilizing and/or emulsifying component.

6 . The composition of claim 5 , wherein the stabilizing and/or emulsifying component is present in the composition in an amount of 0.1% to 10% by weight, based on the total weight of the composition.

7 . The composition of claim 1 , wherein the composition further comprises an artificial tanning agent.

8 . The composition of claim 1 , formulated as a cream, dispersion, emulsion, gel, ointment, lotion, foam, spray, or tonic.

9 . (canceled)

10 . A topically-applicable cosmetic/dermatologic formulation-composition for ultraviolet-photoprotection of skin, scalp, lips, mucous membranes, and/or hair against the damaging effects of ultraviolet irradiation comprising (a) an active sun block agent and (b) a micronized, non-solubilized natural wax, formulated into (c) a topically-applicable, cosmetically/dermatologically-acceptable vehicle, diluent or carrier.

11 . A water-resistant and/or photoprotective composition comprising:
a. an aqueous phase comprising from 20% to 80% by weight of the composition, based on the total weight of the composition; b. an oil phase comprising from 5% to 50% by weight of the composition, based on the total weight of the composition, wherein the oil phase comprises an organic active sun block agent; and c. a micronized, non-solubilized, natural wax comprising 1% to 5% by weight of the composition, based on the total weight of the composition; and d. a stabilizing and/or emulsifying component comprising 1% to 10% by weight of the composition, based on the total weight of the composition; wherein the wax has a D50 particle size of 2 to 50 μm, and a melting point of 70 to 100° C.

12 . A method of mitigating the effects of ultraviolet irradiation on human skin, scalp, lips, mucous membranes and/or hair by applying the composition of claim 1 thereto, in an amount effective to at least partially mitigate the effects of ultraviolet irradiation.

13 . (canceled)

14 . (canceled)

15 . A method of mitigating the effects of ultraviolet irradiation on human skin, scalp, lips, mucous membranes and/or hair by applying the composition of claim 10 thereto, in an amount effective to at least partially mitigate the effects of ultraviolet irradiation.

16 . A method of mitigating the effects of ultraviolet irradiation on human skin, scalp, lips, mucous membranes and/or hair by applying the composition of claim 11 thereto, in an amount effective to at least partially mitigate the effects of ultraviolet irradiation.
