Abstract
Compositions, methods, etc., directed to the stable delivery of benzoyl peroxide (BPO) or other suitable oxidizers into difficult substrates using low viscosity, lipophilic solvents, such as for stain removal or modification. For example, the compositions, methods, etc., can be used to remove autofluorescent organic stains such as pink stains caused by Streptoverticillium reticulum in marine vinyl or any other suitable substrate.
Claims24
A composition comprising an oxidizing agent carried in an organic solvent having a polarity of about 2 to 3, a viscosity of about 0.3 cP to 1.0 cP, and a vapor pressure of 15 to 250 mm Hg, wherein a coating of the organic solvent applied to a marine vinyl fabric with a fine brush will fully evaporate at the surface within at least about 10 seconds at a temperature of 20° C., wherein the oxidizing agent comprises peroxide, benzoyl peroxide, ozone, percarbonate, perphosophate or hydrogen peroxide.
The composition of 21 wherein the composition consists essentially of about 3% to 25% benzoyl peroxide in about 97%-75% xylene (w/w).
The composition of 21 wherein the composition consists essentially of about 10% to 15% benzoyl peroxide in about 90%-85% xylene (w/w).
The composition of 21 wherein the composition consists essentially of about 11% benzoyl peroxide in about 89% xylene (w/w).
