What is dimethicone?
201 Mhttps://www.sn-tin.com/ethyl silicone oil is a novel silicone synthetic material. The appearance is colorless and transparent oily liquid. Its chemical composition is straight-chain polymethylsiloxane with the structural formula:

Due to the stability of the silicone-oxygen bond and the hydrophobicity of methyl, as well as the structural characteristics of the methylsiloxane ensemble poly, the methyl silicone oil has good heat resistance. High flash point, non-volatile, viscosity coefficient is small, while the compression force is large, surface tension is small, chemical stability, good electrical (insulation), and water and moisture resistance, non-toxic effect on living organisms (including humans). In order to make methyl silicone oil in other objects on the surface of the formation of thin films or made of rubber-like solid material, can be heated at high temperatures (250-300 ℃) or add the appropriate catalyst (generally with peroxide) for curing treatment. The use of methyl silicone oil temperature range of 50-180 ℃.
Methyl silicone oil of different viscosity, their physicochemical properties and characteristics of the parameters also have certain differences. There are 201-10, 201-50, 201-100, 201-350, 201-500, 201-800, 201-1000 and other grades according to the viscosity of the product. Other special viscosity specifications can also be made according to user requirements.
Non-toxic, odorless, tasteless

01
It does not affect the appearance and aroma of the final product, and does not cause irritation and allergy to the skin;
It has a very good sense of ease of use and stretchability.
02
The use of medium-viscosity methyl silicone oil in a variety of skin care products can improve the stretchability of cosmetics on the skin, and play a protective effect on the skin;
Very good hydrophobicity and smoothness.
03
Silicone oil formulated hair care products such as hair oil, hair cream, mousse, etc., can make any temperature of the hair combed into the desired hairstyle, and can effectively prevent the external moisture infiltration or water evaporation imbalance;
Good resistance to ultraviolet radiation
04
It will not oxidize and deteriorate under ultraviolet rays and cause irritating effect on skin, and it will not be lost due to seawater bathing or sweating, so it can effectively prevent the harm of ultraviolet rays.
No skin irritation, high safety for human body

05
It has certain effect on certain skin diseases, such as eczema neurodermatitis and occupational dermatitis with difficulty in sweating;
Have good gas permeability and anti-static elimination
06
Rubbed skin containing polysiloxane skin cream static electricity all eliminated, and have obvious dustproof effect good gas permeability, even if the formation of silicone film on the skin does not affect the sweat discharge, hindering the skin breathing;
Chemical stability
07
With other cosmetic raw materials do not react, added silicone oil foundation cream, can protect the skin from pigment, solvent damage.
