The name Siloxane is derived from Silicon, Oxygen and alkane.
They are a family of chemical substances composed of primarily of silicon.
Usually found in cosmetic products, (makeup, crème, deodorant…) and in cleaning as a whole, in paint, etc.
They are used for they particular chemical properties: they are odorless, colorless, non-greasy, easy to apply and dry rapidly.

This family encompasses multiple categories of substances: Cyclotetrasiloxanes (D4), Cyclopentasiloxanes (D5) and Cyclohexasiloxanes (D6).

This gives a slippery and silky feeling when applied to the skin and hair and allows the product to spread more easily.

The basic structure common to all cyclomethicones is a cyclic backbone of siloxane units (i.e., silicon and oxygen with molecules of carbon and hydrogen attached, all very common elements found in nature).
Shorthand nomenclature is based upon the number of siloxane groups in the cyclic structure.
Thus, Decamethylcyclopentasiloxane (also known as cyclopentasiloxane or just D5) has five of these groups.

The cyclosiloxanes octamethylcyclotetrasiloxane (D4), Decamethylcyclopentasiloxane , and dodecamethylcyclohexasiloxane (D6) are cyclic volatile methyl siloxane (cVMS) substances with four, five, and six siloxane groups, respectively.

D5 and D6 are commonly used in cosmetics as emollients, hair and skin conditioning ingredients, and solvents.

The ingredients can be used in hair conditioning products where the product is washed off when used or in skincare products, personal deodorants, and colour cosmetics where the product is left on the skin.
Restrictions currently apply where D4 and D5 are rinsed off; the new proposed restriction will apply to all leave-on uses and extend the rinse-off restriction to D6.

Decamethylcyclopentasiloxane also gives cosmetic products a silky texture.

-Skin care:
The hydrating properties of Cyclopentasiloxane are great for the skin as Decamethylcyclopentasiloxane traps moisture, making the skin smooth and soft.
Decamethylcyclopentasiloxane is used in lightweight products as D5 siloxane does not penetrate the skin but rather evaporates quickly.
Further, Decamethylcyclopentasiloxane skin care has anti-aging properties and is a great ingredient to be used in lotions

-Hair care:
Decamethylcyclopentasiloxane is a great conditioner for hair because of its lubricating properties.
Decamethylcyclopentasiloxane is commonly used in shampoos, hair conditioners, hair sprays, anti-frizz, and hair detangling products.
Decamethylcyclopentasiloxane forms a layer on the hair, protecting and preventing it from damage while also allowing the product to spread easily and evenly

-Cosmetic products:
Decamethylcyclopentasiloxane is used in makeup and makeup removers because it is non-comedogenic and does not block pores
-Decamethylcyclopentasiloxane is used Emollient, Hair conditioning, Skin conditioning
-Decamethylcyclopentasiloxane works great with heavier silicones or oils because the compound makes them easier to spread.
-Decamethylcyclopentasiloxane actually works well with most—if not all—types of ingredients.

-Decamethylcyclopentasiloxane is used Hair detangling products, Waterproof mascara, Foundation, Hair spray, Shampoo, Body lotion
-Decamethylcyclopentasiloxane are used in some cosmetic products thanks to their unique sensory benefits and properties, as long lasting effect in lipstick.
-Decamethylcyclopentasiloxane are smoothing:
Decamethylcyclopentasiloxane give products like creams or make-up a silky, spreadable, luxurious texture.
Decamethylcyclopentasiloxane also give shine and softness in shampoo and other hair care products.

-Decamethylcyclopentasiloxane has good compatibility with most alcohols and other cosmetic solvents and is widely used in cosmetics and human body care products, such as skin care, sunscreen, makeup, hair conditioning products.
-Decamethylcyclopentasiloxane can be directly used as a carrier, the main raw materials, can also be used as additives.

That’s a lot of things.

FEATURES of DECAMETHYLCYCLOPENTASILOXANE:
* Volatile carrier
* Compatible with a wide range of cosmetic ingredients
* Low surface tension
* Imparts soft silky feel to the skin

* Excellent spreading
* Leaves no oily residue or build up
* Detackification
* Non-greasy

A FEW POTENTIAL BENEFITS of PRODUCTS CONTAINING DECAMETHYLCYCLOPENTASILOXANE:
*Seals hydration:
When used on hair, Decamethylcyclopentasiloxane coats the hair shaft and guards against water loss.
The compound works similarly on the skin by creating a barrier that locks in moisture.

*Evaporates quickly:
Decamethylcyclopentasiloxane is often used in cosmetics and health and beauty products that require faster drying times (think deodorants, sunscreens, and moisturizers).

*Spreads easily:
Like other types of silicones, decamethylcyclopentasiloxane in cosmetics applies and spreads easily, leaving a silky smooth texture and a non-greasy finish.

*Has a lightweight feel:
Some silicones are heavy, but Decamethylcyclopentasiloxane has a lightweight feel.
This characteristic is especially helpful in products like hair sprays and shampoos.

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 Decamethylcyclopentasiloxane are also precursors to the polymer.
The catalyst is again KOH.

ADVANTAGES of DECAMETHYLCYCLOPENTASILOXANE:
• Volatile carrier
• Compatible with a wide range of cosmetic ingredients
• Low surface tension
• Imparts soft silky feel to the skin

• Excellent spreading
• Leaves no oily residue or build up
• Detackification
• Non-greasy

WHAT ARE THE NEMEFITS of DECAMETHYLCYCLOPENTASILOXANE IN SKINCARE?
When applied, DecamethylcyclopentasiloxaneV has a silky and slippery texture that creates a protective barrier on the skin and hair.
Decamethylcyclopentasiloxane in hair products may help prevent breakage, detangle, and reduce frizz.
