IOTA D5 Cyclopentasiloxane
Description:

Chemical Name: Cyclopentasiloxane

CAS ：541-02-6

IOTA D5 is a volatile polydimethyl cyclosiloxanes, mainly by decamethyl cyclopentasiloxane composition. Product is clear, odorless, basically odorless, non-greasy.

Application:

IOTA D5 Because of its volatility it can provide a silky feel and have good compatibility with a variety of cosmetic ingredients, low crystallization temperature , good spreadability. It can be widely used in cosmetics as following:

1. Antiperspirant, deodorant: active salt instantaneous carrier;

2. Hair Care: improve wet combing without residue;

3. Skin Care: non-comedogenic original softeners and drug carriers;

4. Perfume: the release of flavor and provide a smooth skin feeling non-cold feeling.
