Cyclohexasiloxane is one of several forms of synthetic, cyclic (meaning the molecule is circular rather than straight or crosslinked) silicone used in cosmetic formulas to improve texture and enhance skin’s hydration.
Cyclohexasiloxane helps give skin care products a silky-smooth, spreadable consistency, so key ingredients can be delivered evenly to skin.
Cyclohexasiloxane is also known to promote aesthetically pleasing finishes that don’t feel sticky, tacky or greasy after application.
In hair care, Cyclohexasiloxane is used to add shine and reduce frizz.
As a raw material, cyclohexasiloxane is a colourless liquid.
Cyclohexasiloxane is described as a lightweight carrier ingredient since it evaporates from skin, leaving behind the formula’s key ingredients to work effectively.

Cyclohexasiloxane is a common ingredient in skincare and body care products, used to improve the texture of formulations.
While the texture is usually a sensory aspect of the product, in the case of cyclohexasiloxane, it helps the product to be evenly distributed so the key ingredients can improve the skin.
Cyclohexasiloxane also has the added benefit of acting as a protective barrier to the skin, protecting the skin from moisture loss, allergens, and bacteria.
Cyclohexasiloxane is a type of silicone.
Silicones are synthetic polymers with a backbone composed of repeating units of siloxane, which is why silicones may also be referred to as polysiloxanes.

Siloxane is made up of elemental silicon and oxygen.
Often, the terms “silicone” and “silicon” are mistakenly used interchangeably, when they are quite different.
Silicon is the 14th element on the periodic table and the second most abundant element in the earth’s crust after oxygen.
In contrast, silicones are always synthetically produced.

Cyclohexasiloxane is part of a family of small silicones called cyclomethicones.
Cyclohexasiloxane are clear, odorless liquids utilized in skincare products to give your skincare a smooth texture that allows the product’s key ingredients to be delivered evenly to the skin.
Cyclohexasiloxane are part of the silicone family and are used in a similar way to dimethicone, which you may be familiar with.
Cyclohexasiloxane help smooth the texture of products, improve the appearance of scarring, increase the water-resistance abilities of formulations, and emulsify the product.
Cyclohexasiloxane are also better at delivering active ingredients to the skin as they are more volatile than larger silicones and slowly evaporate from the skin.
When Cyclohexasiloxane disappear, they leave behind the formulation’s key ingredients.

Cyclohexasiloxane are also known as cyclosiloxanes, different names for the same class of molecules.
The two most commonly used cyclomethicones are cyclohexasiloxane and cyclohexasiloxane; you may have seen these ingredients somewhere near the bottom of your product’s ingredients list.
Cyclohexasiloxane’s structure forms a ring which makes it more volatile or less stable.
This instability allows cyclohexasiloxane to evaporate when applied to your skin readily.
This characteristic makes cyclohexasiloxane a great ingredient for improving the spreadability of products and ensuring they don’t remain sticky after application.
Cyclohexasiloxane gradually evaporates from the skin, leaving behind the other key components in the product to improve the appearance of the skin.
This action of evaporation makes it an excellent carrier ingredient.

In hair care, Cyclohexasiloxane is used to add shine and reduce frizz.
As a raw material, cyclohexasiloxane is a colorless liquid.
Cyclohexasiloxane is described as a lightweight carrier ingredient since it evaporates from skin, leaving behind the formula’s key ingredients to work effectively.
Cyclohexasiloxane is an organosilicon compound.

Cyclohexasiloxane may be used alone or blended with other cosmetic fluids to provide a fluid base for a variety of cosmetic ingredients.
Cyclohexasiloxane features good solubility in most anhydrous alcohols and in many cosmetic solvents.
Cyclohexasiloxane is a volatile fluid with appreciable vapor pressure at ambient temperature.
Note that the pentamer component (D5) evaporates at a faster rate than the hexamer Cyclohexasiloxane.
By using blends of Cyclohexasiloxane this difference in volatility can be used to vary the residence time of the silicone on the skin.
Unlike other volatile carriers used in the personal care industry, volatile silicone fluids do not cool the skin when they evaporate.
This is a consequence of their unusually low heat of vaporization.

FUNCTION of Cyclohexasiloxane
Used for excellent spreading, fast evaporation leaving no residue or build-up, leaves a unique soft feel and lubricity; non-greasy feel, non-occlusive and non-irritating.
Used in conditioners, hair sprays, face wash, body wash, make-up, sun care, antiperspirants, and deodorants.

Cyclohexasiloxane 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.

Cyclohexasiloxane is a silicone regularly used in cosmetic products.
Cyclohexasiloxane’s commonly found in medical implants, sealants, lubricants, and windshield coatings.
Cyclohexasiloxane is colorless, odorless, non-greasy, and water-thin.
Cyclohexasiloxane doesn’t get absorbed into the skin.
Rather, Cyclohexasiloxane 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.
D5 is known for being able to evaporate and dry quickly. Silicones are also known to repel water and glide easily. This is why they are commonly used as ingredients in lubricants and sealants.

They are also known to form a protective barrier on the skin and hair.
This can help you detangle your hair, prevent breakage, and reduce frizz.

Cyclohexasiloxane can be found in a wide range of personal care products. Examples include:

-hair spray
-sunscreen
-antiperspirant
-deodorant
-hair conditioner
-shampoo
-hair detangling products
-waterproof mascara
-foundation
-eyeliner
-concealer
-moisturizer with SPF
-eye shadow
-hairstyling gel and lotion
-lipstick

Cyclohexasiloxanes belong to the group of siloxanes and are organic silicon compounds.
Cyclohexasiloxane are ring-shaped compounds in which silicon and oxygen are bonded alternately and two methyl groups are additionally attached to the silicon.
Cyclohexasiloxane consists of a ring with 6 silicon and 6 oxygen atoms, the "sister compounds", cyclohexasiloxane consists of a ring with 5 silicon and 5 oxygen atoms and cyclotetrasiloxane (D4) consists of a ring with 4 silicon and 4 4 oxygen atoms.

Mixtures of Cyclohexasiloxane and D6 are also available on the market and are also often used in cosmetics.
The term silicone is often used in public, but this general placeholder does not do justice to the many other types of silicone.
The raw materials should be named here with the exact designation, because the dimethicones, silicone elastomers, dimethiconols, silicone gums and silicone emulsifiers have a different structure and sometimes have completely different properties.
All silicone compounds have a very low water solubility in common and cyclohexasiloxane in particular is also often used in body products, sun protection products and ColorCare because of its low density and stickiness.
