Silicone Elastomer Blend with high natural content

Historically, Silicone Elastomer Blends (SEB) have consisted of a crosslinked silicone network swelled in a silicone carrier fluid that is valued by personal care formulators for the sensory, texture, thickening and optical benefits they provide. However, due to their 100% silicone nature, SEB may be difficult to incorporate into formulations with high levels of organic oils. While equivalent blends featuring organic carrier fluids are able to provide enhanced compatibility, this comes at the cost of affecting their sensory profile. The new DOWSIL™ EL-TIPS Silicone
Elastomer Blend technology utilises a novel crosslinking approach that maximises the level of silicone elastomer when combined with an organic carrier fluid. This new SEB features more than 70% of inherently biodegradable C13-15 Alkane, obtained from a renewable source, sugarcane, which is prepared by bio fermentation and not subject to the standards of the Roundtable on Sustainable Palm Oil (RSPO). The use of the new optimised cross- linking technology opens up new possibilities in terms of skin sensory profile, texturising performance, compatibility and product appearance. This makes this technology particularly suited to consumer formulations with high natural content.
Creating naturally derived formulations for today’s consumers The new SEB has been designed to meet
