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 Decamethylcyclopentasiloxane is manufactured and/or imported in the European Economic Area.
Atmospheric emissions of Decamethylcyclopentasiloxane in the Northern Hemisphere were estimated to 30,000 tonnes per year.
General description of Decamethylcyclopentasiloxane:
Decamethylcyclopentasiloxane is used in personal care products including skin creams, cosmetics, shampoos, deodorants and conditioners.
Decamethylcyclopentasiloxane is also used in various applications such as industrial cleaning fluids and dry cleaning solvents.
Applications of Decamethylcyclopentasiloxane:
Decamethylcyclopentasiloxane can be used as:
-A greener solvent in synthetic chemistry applications.
-A monomeric unit for polymerization by various base catalysts to obtain polysiloxane polymer.
Production and polymerization of Decamethylcyclopentasiloxane:
Commercially Decamethylcyclopentasiloxane is produced from dimethyldichlorosilane.
Hydrolysis of the dichloride produces a mixture of cyclic dimethylsiloxanes and polydimethylsiloxane.
From this mixture, the cyclic siloxanes including Decamethylcyclopentasiloxane 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:
[(CH3)2SiO]5n → n [(CH3)2SiO]5
where n is a positive integer.
D4 and D5 (Decamethylcyclopentasiloxane) are also precursors to the polymer.
The catalyst is again KOH.

Safety and environmental considerations of Decamethylcyclopentasiloxane:
The LD50 for D5 in rats is >50 g/kg.
The environmental impacts of D5 (Decamethylcyclopentasiloxane) and D4 have attracted attention because these compounds are pervasive.
Cyclic siloxanes have been detected in some species of aquatic life.
A scientific review in Canada has determined that “Siloxane D5 (Decamethylcyclopentasiloxane) does not pose a danger to the environment” and a scientific assessment of D5 by the Australian government stated, "the direct risks to aquatic life from exposure to these chemicals at expected surface water concentrations are not likely to be significant."
However, in the European Union, Decamethylcyclopentasiloxane was characterized as a substance of very high concern (SVHC) due to its PBT and vPvB properties and was thus included in the candidate list for authorisation.
Since 31 January 2020, Decamethylcyclopentasiloxane cannot be placed on the market in the European Union in wash-off cosmetic products in a concentration equal to or greater than 0.1 % by weight.

WHAT IS Decamethylcyclopentasiloxane?
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, Decamethylcyclopentasiloxane has a unique fluidity that makes it easily spreadable.
When applied to the skin and hair, Decamethylcyclopentasiloxane gives a silky and soft feeling to the touch and acts as a mild water repellent by forming a protective barrier on the skin.
Decamethylcyclopentasiloxane is becoming more common in hair conditioners, as it makes the hair easier to brush without breakage.
HEALTH RISK of Decamethylcyclopentasiloxane:
Suspected endocrine disrupter and reproductive toxicant (cyclotetrasiloxane).
Ecotoxicology – harmful to fish and other wildlife.
If you use too much on your skin, Decamethylcyclopentasiloxane can stay in your body tissue for over 5 years.
CPS clinical studies found that, when tested on animals, Decamethylcyclopentasiloxane produced tumors, endocrine disruption, neurotoxicity (damage to the brain and peripheral nervous system), organ toxicity (non-reproductive) and skin irritation.
Seems like high prices to pay for “soft and silky” hair and skin!
HOW TO AVOID:
Decamethylcyclopentasiloxane can also be listed as D5.
Read labels on sunscreens and hair products and avoid products that list this as an ingredient.

Decamethylcyclopentasiloxane (D5; CAS No. 541-02-6) is a precursor in the production of siloxane polymers for industry and medicine and is a carrier ingredient in many toiletries and cosmetics.
Decamethylcyclopentasiloxane has a relatively low order of toxicity following acute administration via the oral, dermal, and inhalation routes of exposure.
Decamethylcyclopentasiloxane is not considered to be a dermal or eye irritant or a dermal sensitizer.
There is no appreciable dermal absorption of Decamethylcyclopentasiloxane based on results from in vivo and in vitro studies.
Decamethylcyclopentasiloxane has not been shown to be genotoxic/mutagenic when tested in a number of short-term in vitro and in vivo assays and did not cause reproductive or developmental toxicity in rats.
Inhalation exposure of rats to 160 ppm Decamethylcyclopentasiloxane for up to 24 months produced adverse effects in the liver (weight changes and hepatocellular hypertrophy) and uterus (increased incidence of endometrial adenocarcinoma, endometrial adenoma, and adenomatous polyps in several animals); however, the results of recent mode-of-action studies are consistent with a uterine tumorigenesis mechanism that is not relevant for humans.
Based on the results of the chronic inhalation study, 160 ppm was determined to be the no-observed-adverse-effect level (NOAEL) and was selected as the point of departure for the derivation of the workplace environmental exposure level (WEEL) value.
This NOAEL was adjusted to account for interindividual variability and residual uncertainty regarding upper respiratory tract changes still occurring at 160 ppm.
The resulting 8-h time-weighted average WEEL value of 10 ppm is expected to provide a significant margin of safety against any potential adverse health effects in workers exposed to airborne Decamethylcyclopentasiloxane.

Cosmetic uses of Decamethylcyclopentasiloxane:
Decamethylcyclopentasiloxane can be frustrating to decipher the long chemical names on the label of your favorite cosmetic products.
Simple ingredients like water and alcohol are easy to recognize.
But lengthy chemical names can leave even the most conscious consumers scratching their heads.
Decamethylcyclopentasiloxane (D5) is used in hundreds of cosmetics.
In the past, there was controversy about its potential health and environmental risks.
But the Cosmetic Ingredient Review Expert Panel considers it safe to use in cosmetics.
However, in early 2018 the European Union introduced restrictions on D5 use in cosmetic products that are intended to be washed off before evaporation.
Concentrations above 0.1% in wash-off products were determined to have a risk of accumulating in the water supply.

Decamethylcyclopentasiloxane (D5) is a cyclic siloxane used in the formulation of consumer products as well as an industrial intermediate.
A summary of the previous studies on the toxicology of Decamethylcyclopentasiloxane is provided.
Toxicokinetic studies with Decamethylcyclopentasiloxane after dermal administration demonstrate a very low uptake of due to rapid evaporation.
Following inhalation exposure, exhalation of unchanged Decamethylcyclopentasiloxane and excretion of metabolites with urine are major pathways for clearance in mammals.
Due to this rapid clearance by exhalation, the potential for bioaccumulation of Decamethylcyclopentasiloxane is considered unlikely.
The available toxicity data on Decamethylcyclopentasiloxane adequately cover the relevant endpoints regarding potential human health hazards.
Decamethylcyclopentasiloxane was not DNA reactive or mutagenic in standard in vitro and in vivo test systems.
Decamethylcyclopentasiloxane also did not induce developmental and reproductive toxicity in appropriately performed studies.
In repeated studies in rats with subacute, subchronic and chronic inhalation exposure, mild effects on the respiratory tract typically seen after inhalation of irritating materials, increases in liver weight (28- and 90-day inhalation studies), and a small increase in the incidence of uterine adenocarcinoma (uterine tumor) in female rats (two-year inhalation chronic bioassay) were observed.
The liver effects induced by D5 were consistent with D5 as a weak “phenobarbital-like” inducer of xenobiotic metabolizing enzymes and these effects are considered to be an adaptive response.
Mechanistic studies to elucidate the mode-of-action for uterine tumor induction suggest an interaction of D5 with dopamine signal transduction pathways altering the pituitary control of the estrus cycle.
The resulting estrogen imbalance may cause the small increase in uterine tumor incidence at the highest Decamethylcyclopentasiloxane-exposure concentration over that seen in control rats.
A genotoxic mechanism or a direct endocrine activity of Decamethylcyclopentasiloxane is not supported as a mode-of-action to account for the induction of uterine tumors by the available data.
