INCI Name : Caprylyl Methicone


RJS-4201 Volatile Alkyl Methyl Siloxane Fluid is a caprylyl branched trisiloxane.The siloxane consists of three silicon atoms, which is the shortest Dimethicone, and an octyl group is attached on the middle silicon.

v Improve spreadability, reduce tackiness and greasy feel of vegetable oils


v Carrier for other ingredients
v Dispersing medium for hydrophobic powders and pigments
v Can be used in a wide range of personal care applications such as:
v Skin care (e.g., moisturizers, gels, make-up removers, facial cleansers)
v Sun care
v Color cosmetics (e.g., lipsticks)
v Hair care (e.g., leave-on treatments)
v Antiperspirant/deodorant


Caprylyl Methicone RJS-4201 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%.
