"No silicone oil" has become a "black horse" in the field of washing and protection, which has almost become a reference to judge whether shampoo is excellent or not. It has given many new brands a chance to play to their full potential. Many new brands have emerged, demonizing silicone oil. Because of demonization, many people have a big misunderstanding about the existence of silicone oil.            Silicone oil is generally referred to as organosilicon in the personal care industry. Polydimethylsiloxane, cyclodimethylsiloxane, polydimethylsiloxane alcohol, etc., which are common in the cosmetic ingredient list, are commonly referred to as silicone oil. According to different performance requirements, there are also some modified silicone oils, such as emulsified silicone oil, amino silicone oil, phenyl silicone oil, cationic silicone oil, silicone emulsifier, polyether modified silicone oil (water-soluble silicone oil), silicone resin / gel (silicone resin / resin gel silicone elastomer), which are applied in different cosmetics.            In our life, silicone is ubiquitous, and we will encounter silicone products in our daily life; the condom used in ooxx is silicone oil as lubricant; the prosthesis used for breast augmentation and the silicone pad used for business line extrusion; the sealing rings of silicone gel, electric cooker and insulating cup are all silicone rubber; the solar panel for power generation is silicon film; industrial lubricating oil and brake oil , insulating oil, defoamer, hydraulic oil are inseparable from silicone; paper, textile, energy, lighting and other industries have many traces of silicone.            Organosilicon is also a very important substance for human body. For osteoporosis, organosilicon can relieve pain and even restore the body's self-healing function; it is also an essential element of connective tissue; it can also promote hair growth, strengthen teeth and gums, and make nails healthy.
