Low cost sunscreening formulations having SPF values greater than 40 contain homosalate, octyl salicylate or mixtures thereof, in combination with oxybenzone, and optionally further contain octyl methoxycinnamate, avobenzone or mixtures thereof.

High SPF sunscreen formulations

A dermatologically compatible substantive oil-in-water sunscreen composition is disclosed comprising a block polymer substantive agent and a sunscreening agent. The composition is adaptable for dispensing by a spray means.

Substantive topical composition

The invention encompasses oil-in-water type emulsion formulations having decreased skin rub-in times, comprising a nonaqueous phase, an aqueous phase and an oil-in-water emulsifier, which emulsion formulation also contains a water-in-oil emulsifier.

Emulsions having minimal rub-in times

Sunless tanning method and apparatus

Non-aqueous waterproof oil-based topical compositions containing one or more water-in-oil emulsifiers having an HLB value of about 1 to about 7, e.g., sorbitan sesquioleate, and at least one cosmetic emollient, e.g., extra heavy mineral oil, as well as methods for making such compositions are disclosed. The waterproof compositions are particularly useful as vehicles for non-aqueous waterproof oil-based topical sunscreen compositions.

Non-aqueous waterproof oil-based compositions and method of preparing

Non-aqueous sunscreen oils having a high SPF value and containing a volatile oil such as a volatile silicone oil, an emollient containing esters of straight and branched chain C.sub.10 -C.sub.16 alcohols and C.sub.4 -C.sub.20 mono- or dicarboxylic acids such as tridecyl stearate and an ester of a straight or branched-chain C.sub.10 -C.sub.16 alcohol and a tri(loweralkyl) substituted benzoic acid such as tridecyl trimellitate, esters of branched-chain C.sub.5 -C.sub.10 glycols and C.sub.4 -C.sub.20 mono- and dicarboxylic acid such as the diester of neopentyl glycol and decanoic acid and the diester of neopentyl glycol and octanoic acid and a sunscreening effective amount of at least two UV-B type sunscreens and at least one UV-A type sunscreen.

Non-aqueous high SPF sunscreen oils

There is disclosed a method of cooling overheated skin by applying to the surface thereof a composition comprising on a weight basis about 0.5% to 1.5% hydrolyzed starch-acrylonitrile copolymer sodium salt and water and optional lubricants, dyes, moisturizers, preservatives, and the like.

Skin cooling method

A highly substantive topical composition in the form of an oil-in-water emulsion containing an octadecene-1/maleic anhydride copolymer.

Substantive topical compositions

Novel topical sun-protective PABA formulations are provided which retain good protective index levels, even after moisture exposure. These cosmetically elegant formulations contain certain fatty alcohols and nonionic surfactants, and preferably certain cellulosics.

Substantive PABA compositions

A cosmetically elegant and stable oil in water emulsion for use as a topical anesthetic containing 0.5-15% benzocaine solubilized in water with a dialkyl ester of an alkanedioic acid having the formula ROOC--C.sub.n H.sub.2n --C00R' where R and R' are alkyl groups of from 1 to 4 carbon atoms and n is an integer from 1 to 8.
