tricontanyl PVP is a film-forming, waterproofing, and wear-proofing agent. It is oil soluble and easily formulated into sunscreens, skin care creams, lotions, and general cosmetic products. Tricontanyl PVP is a very versatile ingredient. When used in sunscreens, it facilitates the formulation of high SPFs without the need to significantly increase the use of sunscreen chemicals. The result is products with higher SPF, lower irritancy potential, and greater cost effectiveness. Tricontanyl PVP is also used as a pigment dispersant in color cosmetics, and is particularly useful when titanium dioxide is used to increase SPF values. Studies indicate little to no photoallergy or toxicity.
