Amerchol: SolTerra™ Boost

MIDLAND, Mich.—Amerchol will introduce a new family of ultraviolet (UV) protection-boosting polymers at In-Cosmetics Asia, Nov. 4 to 6, Bangkok, Thailand. Compatible with both inorganic UV absorbers and inorganic/organic blends, the polymers will be marketed as SolTerra™ Boost. SolTerra Boost enables formulators to dramatically increase the sun protection factor (SPF) and persistent pigment darkening protection (UVA rating) of skin care products containing inorganic UV filters, such as zinc oxide and titanium dioxide. The ingredient is derived from cellulose and enhances protection against UVA and UVB rays without negatively affecting viscosity or aesthetics.

Jim Gall, sun care market development manager, Amerchol, noted: “Among FDA-approved actives, zinc oxide has the broadest range of UV coverage. With the boost provided by SolTerra Boost, formulators will now be able to achieve very high SPF (SPF 50+) formulations with all zinc oxide or all inorganic sunscreen filters. This eliminates the need to use oily, sticky and tacky organic sunscreen filters, which are potentially irritating to the skin.” Further, he added, “inorganic UV absorbers such as zinc oxide are much more effective at providing coverage across the full UV spectrum. By combining SolTerra Boost with a product like our ZinClear™ IM Zinc Oxide Dispersions, formulators can more easily achieve full-spectrum protection at higher levels, while maintaining the aesthetics needed for lipsticks, foundations and daily moisturizers.”
