■Application in the field of cosmetics
The application of silicone oil in the field of cosmetics, the United States began in the 1950s, Japan began in the 1960s, China began in the 70s, but in the past decade, development and popularization is very fast. Hair care, care products, skin care products, and make-up products are commonly used. The most widely used and most used is methyl silicone oil. The use of methyl silicone oil in cosmetics has the following characteristics:
1) odorless and colorless, does not affect the appearance and aroma of the final product;
2) Have a very good use of lightness and stretch;
3) Very good hydrophobicity and smoothness;
4) No irritation to the skin and high safety to the human body;
5) It has good gas permeability and does not interfere with skin breathing;
6) Chemical stability, no reaction with other cosmetic raw materials.
For example, the use of medium viscosity methyl silicone oil in various skin care products can enhance the skin's stretchability and protect the skin. Adding methyl silicone oil to face or lipstick can improve the dispersibility of the pigment and improve the stretch and use. The addition of methyl silicone oil to the mousse improves combability. Adding a small amount of methyl silicone oil to the shaving cream can provide lubrication between the skin and the blade.
The silicone oil used in cosmetics should be different from the industrial grade in terms of quality grade and must be carefully selected.
■ Applications in the medical and food fields
Dimethyl silicone oil is not toxic to human body and is not decomposed by body fluids. Therefore, it is widely used in medical and health care. Medical methyl silicone oil (100~1000mPa•s), the United States and Japan have special standards, and China has also been included in the Pharmacopoeia. It is mainly used as an additive for external use and a component of gastrointestinal drugs, and has been put into practical use, but silicone oil cannot be used in the blood system. Using its antifoaming effect, it has been made into oral gastrointestinal augmentation tablets, and pulmonary edema defoaming aerosols and the like. Adding silicone oil to the ointment can improve the penetration of the drug into the skin and improve the efficacy. Some pastes based on silicone oil have good curative effect on scald, dermatitis and hemorrhoids. The anticoagulant effect of silicone oil can be used to treat the surface of the blood reservoir and prolong the storage time of the blood sample.
Methyl silicone oil is used in food production processes. Some countries have regulations in the food law. The use of methyl silicone oil has a dryness range of 300-600 mPa•s and has a special grade grade. It is mainly used for defoaming, demoulding and anti-sticking treatment in food packaging.
■ as defoamer
Because dimethyl silicone oil has small surface tension and is insoluble in water, animal and vegetable oils and high-boiling mineral oils, it has good chemical stability and is non-toxic. It has been widely used in petroleum, chemical, medical, pharmaceutical and food industries as defoamers. In the processing, textile, printing and dyeing, papermaking and other industries, as long as the addition of 10 × 10-6 ~ 100 × 10-6 silicone oil has a good defoaming agent.
