Decamethylcyclopentasiloxane is a silicone fluid commonly used in cosmetics such as deodorants, sunblocks, hair sprays and skin care products to lubricate, waterproof and provide shine. Like all other silicones, this ingredient has a unique fluidity that makes it easily spreadable.
What is Cho molecular formula?
2) Determine the “empirical formula weight” of CHO: 12.011 + 1.008 + 15.994 = 29.013 g. 3) Divide 1) by 2): 116.08 / 29.013 = 4. 4) This means there are 4 “units” of CHO in the molecular formula: CHO times 4 = C4H4O4 <— the molecular formula.
Is Decamethylcyclopentasiloxane water soluble?
Decamethylcyclopentasiloxane (D5), CAS 541-02-6, is a cyclic siloxane used as an intermediate in the production of polydimethylsiloxanes and has a number of secondary uses as a component in consumer products. D5 has a low water solubility (17 ppb) and a boiling point of 211 °C.
