Sprayable film forming compositions for improving the performance of topical preparations
A spray-on film forming composition is designed to work with another topical preparation, such as a conventional cosmetic foundation or skincare product. The film forming composition is in direct contact with the cosmetic or skincare product. The spray-on film forming composition may be applied underneath a topical preparation (as a primer), on top of a topical preparation (as a mask), or both, depending on the benefit conferred. The spray-on film forming compositions of the invention are able to improve wearability and removability, increase shine, and deliver active ingredients. They are very clear, flexible and comfortable.
1. A sprayable film forming composition comprising, by total weight of the composition:
4.7% to 14% of acrylates/VA copolymer;
0.05% to 2.5% of acrylates copolymer;
70% to 85% of water;
0.1% to 1.0% of carrageenan and/or hyaluronic acid;
wherein: the ratio of acrylates/VA copolymer to acrylates copolymer is between 10:1 and 100:1, and
wherein, when the film forming composition is applied to a substrate and allowed to dry, the dried film will have an average porosity between 0.25 μm to 3.0 μm.
2. The sprayable film forming composition of claim 1 wherein the ratio of acrylates/VA copolymer to acrylates copolymer is in the range 10:1 and 30:1, and the composition further comprises (by total weight of the composition):
1% to 5% butylene glycol, propanediol, glycerine, or any combination thereof;
no more than 5.0% of hydrophobic oils;
no more than 2% of surfactants and emulsifiers;
no more than 0.5% of polyurethane.
3. The sprayable film forming composition of claim 2 in the form of an oil-in-water emulsion, comprising 0.01% to 2% of emulsifier and at least one oil-soluble active in an oil phase.
4. The sprayable film forming composition of claim 2 having no hydrophobic oils.
5. The sprayable film forming composition of claim 2 having no surfactants or emulsifiers.
6. The sprayable film forming composition of claim 2 having no polyurethane.
7. The sprayable film forming composition of claim 1 wherein, when the film forming composition is applied to a substrate and allowed to dry, the dried film will have an average porosity between 0.9 μm to 2.5 μm.
8. The sprayable film forming composition of claim 1 further comprising at least one water soluble active.
9. The sprayable film forming composition of claim 8 wherein the at least one water soluble active is hyaluronic acid.
10. The sprayable film forming composition of claim 3 wherein the at least one oil soluble active is tocopheryl acetate.
11. A method of applying a cosmetic or skincare care preparation to a keratinic surface comprising the steps of:
applying a first layer of the spray-on film forming composition according to claim 1 directly to a portion of the keratinic surface;
allowing the first layer of spray-on film forming composition to cure to a dried film;
applying the cosmetic or skincare care preparation over the dried film.
12. The method of claim 11 further comprising the steps of:
applying a second layer of the spray-on film forming composition over the cosmetic or skincare preparation, and
allowing the second layer of spray-on film forming composition to cure to a dried film.
13. A method of applying a cosmetic or skincare care preparation to a keratinic surface comprising the steps of:
applying a cosmetic or skincare preparation directly to a portion of the keratinic surface;
applying a spray-on film forming composition of claim 1 over the cosmetic or skincare preparation;
allowing the spray-on film forming composition to cure to a dried film.
