New Ingredients for Sun Care Ashland Specialty Ingredients Ashland Specialty Ingredients, a commercial unit of Ashland Inc., announced its patent-pending HydroSheer sun care formulation is now available globally. HydroSheer water-resistant sun care formulations 32 Spray May 2013 apply transparently on skin, even in the presence of water. Ashland developed the formulation after it discovered that hydrophobic film, under special formulating conditions, is miscible in water. This is significant in that consumers may now apply sunscreen on skin that is wet, without unsightly whitening effects. “Consumers may now apply or reapply waterresistant sunscreen at any time,” said Anna Gripp, Global Marketing Lead, Skin Care & Sun Care. “There is no longer any need to dry off when using sunscreen formulations with hydrophobic films miscible in water. Patent-pending HydroSheer sun care continuous spray formulations containing our Advantage Plus polymer and select Ceraphyl esters provide clear films and bring an added level of convenience to consumers.” “Establishing a set percentage (w/w) for esters and alcohol in a spray formulation, and adding the Advantage Plus polymer, translates into clear films on wet skin” added Hani Fares, Senior Director, Skin Care Research. Croda Croda’s Solaveil ST-100 is a new titanium dioxide (TiO2) dispersion that combines UV performance with enhanced aesthetics. SOLAVEIL ST-100 offers enhanced UVB protection and, due to a tightly controlled particle size distribution, provides true transparency on the skin. The “sensational” skin feel of Solaveil ST-100 is attributed to its internationally patented silane coating technology, which employs a hydrated silica surface with a hydrophobically modified silane outer coating to deliver a light and luxurious skin feel, suitable for premium sun care and daily skin care applications, without the need for silicone-based dispersions. Solaveil ST-100 has sensory characteristics that allow formulators to achieve novel aesthetics in their final product, according to Croda. It is the first product to be launched under the family name Solaveil Sensation. HallStar The HallStar Co. has launched Polycrylene S1, a new singlet-quenching photostabilizer that helps formulators meet FDA standards for broad-spectrum claims and enhances the water resistance of sun care and daily wear products. Polycrylene S1 allows formulators to combine active ingredients once considered too photo-unstable to be effective. Polycrylene S1 replaces the triplet-quenching portion of Polycrylene (INCI: Polyester-8) with a singlet-state quencher. The result is a photostabilizer that provides better UV protection, according to the company. Like Polycrylene, Polycrylene S1 is also a film-forming polymer that enhances the substantivity of sunscreen formulations, according to HallStar. According to the FDA Final Rule issued in 2011, sunscreens must have a critical wavelength of at Continued on page 42
