Octadecyl Vinyl Ether, Polymer (ODVEP) is the homopolymer of octadecyl vinyl ether. It is a 100% active, water insoluble, waxy, nonionic resin. When cast on a glass plate from a molten state, it forms a continuous, glossy, somewhat soft film. Since it melts at about 45ºC, it can easily be incorporated into waxes where it can be utilized as a melting point depressant. ODVEP can be used as processing modifier for polyolefins. The use of ODVEP as a processing aid in the extrusion of polyolefins provides a smoother surface and give a higher tensile strength, elongation, tear resistance, and impact strength than those extruded without. ODVEP also finds application in cosmetic products, for example as film former or skin-conditioning agent. It can impart transfer resistance and water proofing to cosmetic products and increase volume in hair products. Octadecyl Vinyl Ether, Polymer (ODVEP) is designed to enhance the color of pigmented cosmetics. Its use is clearly indicated in lipstick where it provides gloss and in mascara for volumizing and water resistance. Other uses are indicated in pencils and stick products.Particularly resistant elastic films can be obtained from ODVEP when blended with the polymers and copolymers listed below, and in particular a combination of at least two of said polymers or copolymers (with INCI name specified): Octadecene / MA Copolymer / diethylhexyl sebacate, acrylates copolymer, Polyurethane-acrylate copolymer, lauryl dimethicone, PVP / dimethyl Aminoethylmethacrylate / polycarbamyl / polyglycol ester, PVP / Dimethiconylacrylate / polycarbamyl / polyglycol esters, PPG / IPDI / DPMA Crosspolymer, acrylates copolymer, Acrylates / Stearyl Acrylate / Dimethicone Methacrylate Copolymer, polyvinyl stearyl ether, acrylates / lauryl acrylate / stearyl acrylate / ethylamine oxide methacrylate copolymer.Another application of ODVEP is in Textile (Weatherproofing of fabrics) and Leather. In the tanning process of especially pelts and leather from deer (white tanning), a mixture of unsaturated polymers with polyvinylesters like ODVEP can be applied. ODVEP acts as a dispersing agent for additional used salts and as a wetting agent to the pickled pelts and hides to achieve better penetration of the tanning agents into the hide. ODVEP is further used in printing inks as it provides excellent abrasion and scratch resistance. It offers lower drop point, better hardness, guaranteed maximum particle size, constant and narrow particle size distribution.
