Sprayable sunscreen compositions containg oil-in-water emulsions containing submicron hydrophobic agents and methods of use thereof

A sprayable sunscreen composition comprising:

• an emulsion comprising (i) submicron particles of one or more hydrophobic ultraviolet B ray (UVB) filters or ultraviolet A ray (UVA) filters or ultraviolet (UV) absorbing boosters or other non-UV absorbing hydrophobic agent(s), (ii) an emulsifier system comprising one or more nonionic surfactant(s) or emulsifier(s), and (iii) an aqueous-solute fluid;
• wherein the submicron particles of one or more hydrophobic ultraviolet B ray (UVB) filters or ultraviolet A ray (UVA) filters or ultraviolet (UV) absorbing boosters or other non-UV absorbing hydrophobic ultraviolet B ray (UVB) filters or ultraviolet A ray (UVA) filters or ultraviolet (UV) absorbing boosters or other non-UV absorbing hydrophobic agent(s) are present in an amount from about 0.01% wt. to about 70% wt., the aqueous-solute fluid is present in an amount from about 1.0% wt. to about 98.5% wt., and the one or more nonionic surfactant(s) or emulsifier(s) are present in an amount from about 0.01% wt. to about 10% wt., all based on the total weight of the sprayable sunscreen composition;
• wherein the submicron particles of one or more hydrophobic ultraviolet B ray (UVB) filters or ultraviolet A ray (UVA) filters or ultraviolet (UV) absorbing boosters or other non-UV absorbing hydrophobic agent(s) (i) have an average particle size from about 100 nm to less than about 1000 nm, (ii) have a solubility of less than about 0.1% by weight in water under standard conditions, and (iii) are 85% or more of a size within ±2.0 standard deviations, of the average particle size;
• wherein the one or more nonionic surfactant(s) or emulsifier(s) comprise ester(s) of one or more fatty acid moieties with one or more hydroxyl groups of glycerol or polyglycerol having a HLB from about 3 to about 20, based on the degree of glyceryl units or ethoxyl units, or combinations thereof;
• and optionally ester(s) of one or more fatty acid moieties with one or more hydroxyl groups of sucrose having a HLB from about 2 to about 18, based on the degree of glyceryl units or ethoxyl units, or combinations thereof;
• wherein the one or more nonionic surfactant(s) or emulsifier(s) are sufficient to stabilize the submicron particles of one or more hydrophobic ultraviolet B ray (UVB) filters or ultraviolet A ray (UVA) filters or ultraviolet (UV) absorbing boosters or other non-UV absorbing hydrophobic agent(s) in said emulsion, at a level from about 0.05% w/w to about 70% w/w of said one or more hydrophobic agent(s), in said emulsion;
• and
• wherein the sprayable sunscreen composition has a viscosity sufficient to form a spray of preset or desired droplet size upon dispensing from a spray dispenser.
