Silicone elastomers are versatile materials designed to thicken water-in-oil and water-in-silicone formulations as well as silicone oils. Waterless sunscreen systems can be easily formulated by converting these liquids, including UV filters, into gel form. The elastomer particles trap the fluid to be thickened, forming a gel matrix structure. Elastomers can be mixed at room temperature and diluted with silicone oil or solvents to reduce their viscosity.
In addition to its gelling properties, it has a dry, non-greasy yet silky smooth skin feel while absorbing quickly into the skin. These are always important criteria when consumers choose their favorite sunscreen. In addition, elastomeric films can be used to form a layer that holds fragrance or active ingredients, ideal for providing controlled release properties and providing long-lasting effects.
