Description:
MYD5 is volatile polymethylsiloxane fluids, Mainly contains decamethylcyclopentasiloxane. It is colorless, tasteless, essentially odorless and non-greasy.
Applications:
MYD5 is used for a wide range of personal care applications because of its volatile nature, provide a soft silky feel, compatible with a wide range of cosmetic ingredients, lower crystallization point and spreading properties:
• Antiperspirants, deodorants: is transient carrier for active salts
• Hair care: improves wet combing, yet leaves no residue
• Skin care: non-comedogenic emollient and carrier
• Perfumes: delivers fragrance and gives skin a smooth non-cooling feel
MYD5 complies with the non-volatiles requirements of US Pharmacopoeia.
Recommended use levels:
• Antiperspirants, deodorants : 3-10%;
• Hair care: 1-5%;
• Skin care: 3-10%;
• Perfumes: 0.5-3%.
Advantages:
MYD5 has the following properties:
• Imparts soft silky feel to the skin
• Excellent spreading
• Detackification
• Non-greasy
