An improved broad-spectrum sunscreen formulation is provided. The sunscreen formulation comprises at least one organic sunscreen filter, at least one of which avobenzone, and an alkyl benzoate comprising 25-55 mole % C12-14 alkyl benzoate and 45-75 mole % C12-C15 alkyl benzoate.

Alkyl benzoate solubilized organic sunscreen filters

The present invention relates to the use of Styrenated Phenol Ethoxylates as surfactants in emulsion polymerization. The present invention further relates to the use of both anionic and nonionic Styrenated Phenol Ethoxylates in emulsion polymerization. Latexes with small average particle and narrow particle size distributions are obtained. Prepared latexes also have low coagulum levels and exhibit excellent mechanical and chemical stability.

Styrenated phenol ethoxylates in emulsion polymerization

The present invention provides a dispersant for aqueous and non-aqueous systems which can disperse insoluble fine powders in aqueous and non-aqueous liquids in a short period of time and give long-term dispersion stability to the resulting dispersions. The dispersant is a compound of the formula wherein CY is selected from the group consisting of aliphatic monocyclic compounds having one double bond and aliphatic polycyclic compounds with or without one double bond, or with or without bridge carbons; (n+x+y+z)&#x3e;1; and R&#x2550;&#x2014;H, &#x2014;SOM, &#x2014;COM, &#x2014;POM, &#x2014;OCR' wherein M=H, or Na, K, Li, Ca, Mg, NH4, NH(R), NHR, N(R)where Ris selected from the group consisting of C-Calkyl and C-Chydroxyalkyl; and R&#x2032;&#x2550;C-Calkyl or alkenyl.
