  • Cyclopentasiloxane MYD5

    Cyclopentasiloxane MYD5

    MYD5 is volatile polymethylsiloxane fluids, Mainly contains decamethylcyclopentasiloxane. It is colorless, tasteless, essentially odorless and non-greasy.


    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
