Caprylyl Methicone Silway506


Silway 506 Fluid is a caprylyl branched trisiloxane as described in Figure 1. The siloxane consists of three silicon atoms, which is the shortest Dimethicone, and an octyl group is attached on the middle silicon.

Typical Applications

• Carrier for other ingredients

• Dispersing medium for hydrophobic powders and pigments

• Can be used in a wide range of personal care applications such as:

Skin care (e.g., moisturizers, gels, make-up removers, facial cleansers)

Sun care

Color cosmetics (e.g., lipsticks)

Hair care (e.g., leave-on treatments)

Silway 506 Fluid is added into the oil phase and mixed until solved or dispersed evenly. Due to the presence of the caprylyl group on the silicone backbone, this ingredient has good compatibility with a wide range of organic ingredients and pigments while maintaining very good spreading.

This results in a less dry feel and a richer feel when compared to volatile silicones – but still very light due to the moderate volatility. Being nonflammable and very compatible, this material is easy to handle and to incorporate in a broad range of formulations including lipsticks and pigmented formulations. It can help to reduce white residues in formulations containing a high level of volatile materials. Recommended use level is between 5 and 20%.
