Personal cleansing and shaving films
Personal care composition in the form of a dry film useful in cleansing or shaving. The film includes at least one water soluble polymer in an amount of about 45 to about 82 weight %, based on total weight of dry film, and, when used for cleansing, at least one surfactant in an amount of about 18 to about 55 weight %; based on total weight of dry film. The at least one water soluble polymer can include blends of polymers. Other additional ingredients for use in the film include plasticizers and/or neutralizing agents. The personal cleansing dissolvable films provide improved aesthetics, foaming, cleansing, moisturizing and lubricity.
1 . Personal care composition comprising:
at least one water soluble polymer in an amount of about 45 to about 82 weight %; and
at least one surfactant in an amount of about 18 to about 55 weight %;
wherein the composition is a dry film, and weight % based on total weight of dry film.
2 . The at least one water soluble polymer of claim 1 further comprising synthetic polymers, natural polymers, or combinations thereof.
3 . The at least one water soluble polymer of claim 2 wherein the at least one water soluble polymer is at least one or more natural polymers comprising pullulan, starch, or combinations thereof.
4 . The at least one water soluble polymer of claim 3 wherein the at least one water soluble polymer comprises a ratio of pullulan to starch in the amount of about 100:0 to 75:25.
5 . Personal care composition of claim 1 further comprising at least one plasticizer, and
the at least one water soluble polymer further comprising a blend of starch and pullulan.
6 . Personal care composition of claim 5 , wherein the at least one plasticizer is present in an amount greater than 15 percent based upon weight of starch in the composition.
7 . Personal care composition of claim 6 , where in the at least one plasticizer is present in an amount greater than 18 percent based upon weight of starch in the composition.
8 . Personal care composition of claim 1 further comprising at least one plasticizer, and the at least one water soluble polymer further comprising starch, wherein the at least one plasticizer is present in an amount greater than 18 percent based upon the weight of the starch in the composition.
9 . The at least one surfactant of claim 1 further comprising sodium lauryl sulfate, ammonium lauryl sulfate, sodium laureth sulfate, ammonium lauryl sulfate, cocamidopropyl betaine, lauramidopropyl betaine, disodium cocoamphodiacetate, sodium lauroyl sarcosinate, TEA-cocoyl glutamate, or decyl glucoside or combinations thereof.
10 . Personal care composition of claim 1 further comprising at least one neutralizing agent present in an amount sufficient to neutralize the free acid groups of the water soluble polymer.
11 . Personal care composition of claim 1 wherein the film is a cleansing film or a shaving film.
12 . A method of cleansing skin and/or hair comprising:
wetting the film of claim 1 with water in an amount sufficient to create a lather, and
applying the lather to the skin and/or hair.
13 . A method of shaving a substrate comprising:
wetting the film of claim 1 with water in an amount sufficient to create a lather, and
applying the lather to the substrate to be shaved.
14 . A method of preventing dissolvable films from blocking comprising coating the film of claim 1 with a starch selected from the group consisting of unmodified and modified starch.
15 . The method of claim 11 wherein the starch is hydrophobically modified.
