As a low viscosity liquid of high polarity with elegant slip and feel, it is widely used in sun care, color cosmetics and skin care. HallBrite® BHB significantly increases the SPF performance of sun protection products through the reduction of electron transfer and photoprotection mechanisms.
- Olivem® LV Flex, a very versatile, light oil-in-water liquid crystal emulsifier, provides a pleasant skin feel even in a high oil phase system.
