IngreSil BD5-910 is a silicone elastomer in gel form. It's an ultra high molecular weight crosslinked silicone copolymer dispersion in Cyclopentasiloxane. It is frequently used in decorative cosmetics as it is velvety smooth and gives a matte, powdery appearance, allowing it to cover tiny wrinkles and skin imperfections. This ingredient has some cleansing properties, making it a useful additive in skin care products. IngreSil BD5-910 also improves skin affinity of make up products and it increases the longevity of color cosmetics. It's easy to (cold) formulate and imparts a non-tacky feel to the formulation.
