Hair Conditioning uses:
Cyclomethicone 5 is recognized as multifunctional ingredients in a variety of hair care products.
With their unique chemical and physical properties, these highly versatile materials not only condition hair but can be used to add shine, making combing easier.
Both are suitable for dry combing results and wet combing.
Cyclomethicone 5 also enhances hair strength, repairs damaged hair, gives a perception of moisturization, aids curl retention, controls frizz, and adds volume—or even reduces volume.
Cyclomethicone 5 is commonly used in shampoos, hair conditioners, hair sprays, anti-frizz, and hair-detangling products.
Cyclomethicone 5 forms a layer on the hair, protecting and preventing it from damage while also allowing the product to spread easily and evenly.
Benefits And Uses of Cyclomethicone 5:
Cyclomethicone 5 is preferred for its conditioning, viscosity controlling, and water-repelling properties.
Cyclomethicone 5 is an excellent solvent and can be found in countless products.
Cyclomethicone 5 is documented to be an anti-static agent, non-greasy, non-sticky, and is acclaimed for giving a slippery feel and a dry non-cooling sensation on evaporation.
Cyclomethicone 5 evaporates quickly and does not leave behind any residue.
This commands application in formulating deodorants and antiperspirants.
Cyclomethicone 5 makes spreading products a breeze because of its unique fluidity.
Cyclomethicone 5 provides stability to the formulation and prevents it from splitting.
Cyclomethicone 5 is used to deposit active ingredients on the skin and hair, thereby enhancing the efficacy of the formulation.
Cyclomethicone 5 is used in serums, lotions, hair sprays, face and body mists, sunscreens, non-sticky oils, etc.
Cyclomethicone 5 works by carrying the key ingredients of a formulation into the skin and hair for better absorption.
Lacking penetrative powers, Cyclomethicone 5 simply forms a layer over the skin.
Cyclomethicone 5 makes the surface slippery and then evaporates owing to its volatility.
Cyclomethicone 5 offers minimal benefits to the skin.
Companies primarily add Cyclomethicone 5 to skincare products to improve their sensory feel and texture.
However, Cyclomethicone 5 has other properties that boost the effectiveness of formulations.
Benefits:
Cyclomethicone 5 is an ideal carrier for cosmetics without the oily feel.
Cyclomethicone 5 rapidly evaporates leaving the skin feeling smooth and silky.
Skin Care Benefits:
When applied, Cyclomethicone 5 has a silky and slippery texture that creates a protective barrier on the skin and hair.
Cyclomethicone 5 in hair products may help prevent breakage, detangle, and reduce frizz.
Here are a few potential benefits of products containing D5:
Seals hydration:
When used on hair, Cyclomethicone 5 coats the hair shaft and guards against water loss.
Cyclomethicone 5 works similarly on the skin by creating a barrier that locks in moisture.
Evaporates quickly:
Cyclomethicone 5 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, Cyclomethicone 5 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 Cyclomethicone 5 has a lightweight feel.
This characteristic is especially helpful in products like hair sprays and shampoos.
Lightweight carrier:
Cyclomethicone 5 is an effective carrier, or solvent, due to its ability to evaporate quickly.
Cyclomethicone 5 helps to evenly coat the skin with active ingredients without leaving a heavy, sticky, or tacky residue after application.
Cyclomethicone 5 leaves the active ingredients to work from the skin’s surface as they evaporate.
Forms a protective barrier:
Cyclomethicone 5 also acts as an emollient that adds a protective barrier to the skin.
However, Cyclomethicone 5 evaporates quickly and does not stay on the skin surface, so it does not leave a sticky feel.
Cyclomethicone 5 leaves a protective yet breathable layer on the skin.
Facilitates a smooth application and delivery:
Cyclomethicone 5 helps make formulations feel smooth and silky for a smooth and easy application.
Cyclomethicone 5 allows products to spread evenly over the skin so that all areas of the skin receive key ingredients from a product.
Improves the appearance of scars:
Many silicone gel preparations use Cyclomethicone 5 as a carrier to deliver other silicone ingredients to the skin.
An older study found that silicone gel preparations improved the texture, height, and appearance of hypertrophic scars and keloids.
However, Cyclomethicone 5 is important to note that the researchers conducted this study on a small sample size of 30 people.
Inexpensive:
Cyclomethicone 5 is generally less costly than other silicone ingredients.
Therefore, a person may find that products containing Cyclomethicone 5 are more affordable.
Other Benefits:
No Oily Residue
Improves Efficacy of Antiperspirants
Dry, Non-Greasy Feel
Improves Wet Combing
Greater Flexibility in Formulating Cosmetic Products
Concentration And Solubility of Cyclomethicone 5:
Cyclomethicone 5 is insoluble in water and is soluble in alcohols, silicones, and solvents.
Cyclomethicone 5 is suggested that its concentration be kept between 3%-10% for deodorants and skin care products, though Cyclomethicone 5 can be increased up to 20%.
Cyclomethicone 5 Formulations:
Cyclomethicone 5 adds wonderful slip to our products and helps reduce tackiness.
Small concentrations of Cyclomethicone 5 add a really gorgeous, expensive-feeling skin feel.
Higher concentrations of Cyclomethicone 5 help “lighten” products, speeding up dry down/absorption speeds.
Cyclomethicone 5 is commonly used as a diluent in hair oils to create products that don’t leave the hair looking greasy.
A small amount of oil will be diluted in a larger amount of Cyclomethicone 5.
When that is applied to the hair the Cyclomethicone 5 will readily evaporate, leaving a tiny amount of well-distributed oil behind on the hair.
In cosmetics, you’ll find Cyclomethicone 5 in all kinds of cream cosmetics, where Cyclomethicone 5 provides body to the cosmetic and then evaporates readily after application, leaving behind the pigment without any added oil that would compromise wear time.
Compatibility of Cyclomethicone 5:
Cyclomethicone 5 can be tricky to formulate with as they are neither completely oil or water loving.
Cyclomethicone 5 is stated as being miscible with Mineral oil, isododecane, polydecane, almond oil, Jojoba oil, Soybean oil, Sunflower oil, Isopropyl Myristate, C12-15 Alcohol Benzoate and Capric/ Caprylic Triglyceride.
Origin of Cyclomethicone 5:
Cyclomethicone 5 is made by the hydrolysis of dichloride.
This process produces a mixture of polydimethylsiloxane and cyclic dimethyl siloxanes.
This on further distillation produces a polymer mixture of Cyclomethicone 5.
Production And Polymerization of Cyclomethicone 5:
Commercially Cyclomethicone 5 is produced from dimethyldichlorosilane.
Hydrolysis of the dichloride produces a mixture of cyclic dimethylsiloxanes and polydimethylsiloxane.
From this mixture, the cyclic siloxanes including Cyclomethicone 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:
[(CH3)2SiO]5n → n [(CH3)2SiO]5
D4 and Cyclomethicone 5 are also precursors to the polymer.
The catalyst is again KOH.
