What are the advantages of silicone oil used in cosmetics?
Silicone oil is contained in about 90% of the shampoos we use. It plays an important role in helping to make our hair smooth and silky. If we use shampoos without silicone oil, our hair will feel very rough after washing. Since silicone oil has such an effect in shampoos, what are the advantages when it is used in cosmetics?
Silicone oil has excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertness and low surface tension. In addition, it has a low viscosity-temperature coefficient and high compression resistance. Some varieties also have radiation resistance.
Silicone oil can be well used in the production of cosmetics to improve the performance of cosmetics. The combination of its low surface tension and viscosity enables other components of cosmetics to easily spread into a thin film on the skin without a sticky feeling. The tack-reducing property of silicone oil allows it to be combined with petrolatum, paraffin, beeswax, lanolin, etc. to obtain non-greasy products. Volatile silicone oil can endow cosmetics with properties such as quick-drying, smoothness, anti-fouling and good luster. As a carrier for cosmetics, it can quickly dissipate and make other cosmetic components form a uniformly distributed thin film, which is very important in eye cosmetics and nail polish.
In hair care products, silicone oil can add luster to the hair, and at the same time, it can play a role in styling and preventing the hair from sticking together. In shampoos, silicone oil can make the hair easier to comb. In skin care products, the hydrophobic film formed by silicone oil can not only prevent other components from being washed away by water but also keep the skin breathing normally. At present, silicone oil has become an important ingredient or auxiliary agent in many cosmetics.
The above are the advantages of silicone oil. When it is used in hair care products, there are also disadvantages. Just like when it is used in hair care products, while making the hair smooth, it may also increase the possibility of hair loss. How to choose specifically depends on everyone's own judgment.
