Silway 506
 
 
CAPRYLYL METHICONE （LONG CHAIN ALKYL SILICONE OIL）SILWAY506
 
Silway 506 Fluid is a caprylyl branched trisiloxane. The siloxane is composed of three silicon atoms, making it the shortest form of Dimethicone. An octyl group is attached to the middle silicon atom.
 
 
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 （Skin and Sun Care Product）
  • Color cosmetics (e.g., lipsticks)
  • Hair care (e.g., leave-on treatments)
  • Antiperspirant/deodorant

Usage
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%.
