Is cyclomethicone a D5?
D5 can be added as an ingredient in silicone mixtures used in cosmetic applications such as skin creams and deodorants, where it may be labelled “cyclomethicone” or “cyclopentasiloxane”.
What is cyclomethicone used for?
Cyclomethicone is used in a wide variety of cosmetic applications such as antiperspirants, deodorants, lotions, creams, hair sprays, bath oils, makeup and nail polish. For making clear sprays, pour Cyclomethicone in bottle and add fragrance oil.
What is D5 in deodorant?
D5 is colorless, odorless, non-greasy, and water-thin. It doesn’t get absorbed into the skin. Rather, it evaporates quickly away from it. This property makes it a useful ingredient in cosmetic products that need to dry quickly, like antiperspirants and hair sprays. It also has lubricating properties.
Is cyclomethicone harmful?
Cyclomethicone is a substance classified as toxic to reproduction category 3 and according to the cosmetic directive 2003/15/EC a safety evaluation for its use in cosmetic products is needed.
What is D5 silicone?
D5 is an odourless, colourless liquid mostly used as an intermediate or basic raw material in the production of silicone rubbers, gels and resins. When used as an intermediate during the manufacturing process, virtually all D5 is consumed with only a tiny amount remaining in final products.
What is D4 and D5 silicone?
D4 and D5 are cyclosiloxanes mainly used as monomers for silicone polymer production. They also have a direct use in personal care products. D4 has been identified as a persistent, bioaccumulative and toxic (PBT) and very persistent very bioaccumulative (vPvB) substance. D5 has been identified as a vPvB substance.
How do you spray a room with cyclomethicone?
Perfect for making Room sprays/Mists. Just add 5-20% fragrance oil to the Room mist base. For making clear sprays, pour Cyclomethicone in bottle and add fragrance oil.
Is cyclomethicone harmful for skin?

What is D5 ingredient?
What is cyclopentasiloxane? It is a conditioning ingredient in hair and skin products. To begin with, its full chemical name is decamethylcyclopentasiloxane and it is commonly known as D5. It is responsible for a silky and slippery feel to the skin and hair (source).
Is cyclomethicone safe for skin?
Is cyclomethicone safe in lube?
Cyclomethicone and Phenyl Trimethicone (Also synthetic) These are are basic silicone polymers and are often found in silicone lubes and are generally considered to be un-dangerous.
Is cyclomethicone water soluble?
Cyclomethicone is water-soluble, which means it washes out easily and leaves behind minimal product buildup. But even heavier, non-water-soluble types of silicones, like amodimethicone and dimethicone, can be washed out over several shampooings.
What is the chemical name of D5?
?) Decamethylcyclopentasiloxane ( D5) is an organosilicon compound with the formula [ (CH 3) 2 SiO] 5. It is a colorless and odorless liquid that is slightly volatile. The compound is classified as a cyclomethicone.
How is D5 formed from dimethyldichlorosilane?
Commercially D 5 is produced from dimethyldichlorosilane. Hydrolysis of the dichloride produces a mixture of cyclic dimethylsiloxanes and polydimethylsiloxane. From this mixture, the cyclic siloxanes including D 5 can be removed by distillation.
How do you remove D5 from dichloride?
Hydrolysis of the dichloride produces a mixture of cyclic dimethylsiloxanes and polydimethylsiloxane. From this mixture, the cyclic siloxanes including D 5 can be removed by distillation. In the presence of a strong base such as KOH, the polymer/ring mixture is equilibrated, allowing complete conversion to the more volatile cyclic siloxanes:
Is d5 an emollient or an impurity?
D 5 is considered an emollient . In Canada, among the volume used in consumer products approximately 70% were for antiperspirants and 20% for hair care products. 10,000–100,000 tonnes per year of D 5 is manufactured and/or imported in the European Economic Area.
