Abstract

A sunscreen composition includes a sunscreen active, a carrier, and a film former polymer. The sunscreen active may be selected from organic sunscreen actives. The carrier may include an amphiphile monolayer to encapsulate a least a portion of the total amount of the sunscreen active. The film former polymer may include an acrylic film former polymer selected from C 1 -C 30 alkyl (meth)acrylates copolymer. Notably, the sunscreen active may provide enhanced photoprotection at relatively low concentration levels when present with the carrier, including the amphiphile monolayer, and the acrylic film former polymer.

First claim

What is claimed is:

1 . A sunscreen composition comprising:
a sunscreen active including an organic sunscreen active, wherein the organic sunscreen active is present in an amount of greater than zero to less than or equal to 15.0 wt. %, based on the total weight of the sunscreen composition; a carrier selected from a micelle, wherein the micelle comprises an oleosome, wherein the oleosome is present in an amount of 0.8 wt. % to less than or equal to 10.0 wt. %, based on the total weight of the sunscreen composition; and an acrylic film former polymer selected from C 1-30 alkyl (meth)acrylates copolymer, wherein the C 1-30 alkyl (meth)acrylates copolymer comprises acrylates/C 12-22 alkyl methacrylate copolymer, wherein the acrylates/C 12-22 alkyl methacrylate copolymer is present in an amount of greater than zero to less than or equal to 2.5 wt. %, based on the total weight of the sunscreen composition; and wherein the sunscreen composition has a Sun Protection Factor (SPF) greater than or equal to 50.

2 . The sunscreen composition of claim 1 , wherein the sunscreen active comprises avobenzone, diethylamino hydroxybenzoyl hexyl benzoate, octocrylene, octinoxate, octisalate, homosalate, ethylhexyl triazone, bemotrizinol, bis-ethylhexyloxyphenol methoxyphenyl triazine, titanium dioxide, zinc oxide, or combinations thereof.

3 . The sunscreen composition of claim 1 , wherein the sunscreen active is selected from the group consisting of organic sunscreen actives.

4 . The sunscreen composition of claim 1 , wherein the oleosome is selected from Carthamus Tinctorius oleosomes, Prunus Amygdalus Dulcis oleosomes, or combinations thereof.

5 . The sunscreen composition of claim 4 , wherein the oleosome is selected from Carthamus Tinctorius oleosomes.

6 . The sunscreen composition of claim 1 , wherein the oleosome is present in an amount of 1.0 wt. % to less than or equal to 10.0 wt. %, based on the total weight of the sunscreen composition.

7 . The sunscreen composition of claim 1 , wherein the C 1-30 alkyl (meth)acrylates copolymer has a molecular weight of 1,000,000 Daltons or less.

8 . The sunscreen composition of claim 1 , further including one or more boosters, cosmetically acceptable carriers, oils, sterols, amino acids, moisturizers, powders, colorants, pigments, dyes, pH adjusters, fragrances, cosmetic active ingredients, vitamins, preservatives, preservative boosters, foaming agents, chelating agents, cleansers, essential fatty acids, sphingolipids, self-tanning compounds, fillers, emulsifiers, antioxidants, surfactants, additional film formers, chelating agents, gelling agents, thickeners, emollients, humectants, minerals, viscosity and/or rheology modifiers, keratolytics, retinoids, hormonal compounds, alpha-keto acids, anti-mycobacterial agents, anti-fungal agents, anti-microbials, anti-virals, analgesics, anti-allergenic agents, H1 or H2 antihistamines, anti-inflammatory agents, anti-irritants, anti-neoplastics, immune system boosting agents, immune system suppressing agents, anti-acne agents, anesthetics, antiseptics, insect repellents, skin cooling compounds, skin protectants, skin penetration enhancers, exfoliants, lubricants, staining agents, depigmenting agents, hypopigmenting agents, stabilizers, pharmaceutical agents, photostabilizing agents, spherical powders, extracts, absorbents, salicylic acid, alpha and beta hydroxy acids, retinol and its derivatives, or combinations thereof.

9 . The sunscreen composition of claim 1 , further including a booster.

10 . The sunscreen composition of claim 9 , wherein the booster comprises a carbohydrate selected from maize starch, potato starch, wheat starch, rice starch, cassava starch, tapioca starch, barley starch, or combinations thereof.

11 . The sunscreen composition of claim 10 , wherein the booster is present in an amount of greater than zero to less than or equal to 7.5 wt. %, based on the total weight of the sunscreen composition.

12 . The sunscreen composition of claim 10 , wherein the booster comprises Zea Maize starch.

13 . The sunscreen composition of claim 1 , wherein the sunscreen composition is in the form of a lotion or a cream.

14 . A sunscreen method to protect a keratinous surface from ultraviolet (UV) radiation comprising contacting the keratinous surface with the sunscreen composition of claim 1 .

15 . A consumer packaged product comprising the sunscreen composition of claim 1 .

16 . The sunscreen composition of claim 1 , wherein the sunscreen active excludes ethylhexyl methoxycinnamate (octinoxate).

17 . The sunscreen composition of claim 16 , wherein the sunscreen active includes a salicylate.

18 . The sunscreen composition of claim 1 , wherein the sunscreen composition has an in vivo SPF greater than or equal to 50.
