In the past, conventional silicone elastomer gels were often formu-lated with volatile siloxanes. These stabilize the gel’s crosspolymer network and enhance the product’s spreadability. For its new gels ‘Belsil EG 3000’ and ‘Belsil eco EG 3001’, the company developed an alternative formulation concept. Instead of a siloxane-based solvent, these products contain organic substances that are commonly used in the cosmetics sector. ‘Belsil EG 3000’ contains the organic solvent isohexadecane, while ‘Belsil eco EG 3001’ contains a mixture of undecane and tridecane. Isohexadecane is biodegradable to a limited extent. Undecane and tridecane are fully degraded by microorganisms in the environment. Laboratory tests show that the new gels’ range of performance in applications is almost equal to that of siloxane-based products.
