"Silicone oil is a kind of organic siloxane, washing and cosmetics industry is more used for dimethyl silicone oil." Sun Jie told science and Technology Daily reporters.

In the chemical industry, silicone oil is actually polydimethyl siloxane, ring dimethyl siloxane or their derivatives collectively. Silicone oil is not volatile, transparent, non-toxic, non-corrosive liquid, chemical stability, high safety.

In shampoo, silicone oil is known as "polydimethylsiloxane", with good viscosity and ductility, that is, it is very similar to the oils extracted from natural plants.

Our ancestors originally used natural plant extracts to clean their hair and skin. With the development of the chemical industry and the continuous improvement of people's requirements for shampoo products, silicone oil began to be used in shampoo products, up to now has a history of 70 years.

Why do you add silicone oil to your shampoo? It starts with the structure of the hair.

Our hair grows from hair follicles in the scalp and is made mainly of keratin. There are many hairy scales on each hair. Hair the most outside hair scale is 7-10 already dead cell, cover protects hair core in hair surface, healthy hair scale is complete, obedient, because this hair surface is smooth, look burnish is bright.

Sun Jie tells a reporter, when washing hair, adhere to the grease that has lubricated protection effect on hair scale can be washed, when combing hair, hair scale can become warped, this increased the frictional force between the hair, easy to make the hair entangle, aggravated the damage of hair scale thereby. If the hair is dyed and permed, the scales will open and the hair will look dry and dull.

The silicone oil can be adsorbed together with the hair, fill the uneven hair scale raised, reduce the friction between the hair, make the hair easy to comb and have smooth, effectively alleviate the damage to the hair.

At the same time, silicone oil is also a skin moisturizing ingredient, can be covered in the skin to form a protective layer, prevent skin moisture loss, in the application of moisturizer.
