Now people have higher and higher requirements for living health. From skin care equipment to small appliances used in daily life, they are required to be healthy, environmentally friendly, harmless and pollution-free. However, the facial washes and electric toothbrushes that are widely used in the market are recently divided into two categories in terms of materials: silicone and nylon. From the perspective of innovation, the whole beauty industry was shocked by the introduction of medical silicone material. This new concept and technology has been applied to your daily necessities, and more and more people have begun to pursue this material. From the perspective of beauty, the technology of medical silica gel has been quite mature, and has opened a gap with other materials all the way, thus gradually becoming the main core material of beauty industry instruments.
So, how much do you know about silica gel? Among many synthetic rubbers, silica gel is the leader. It is tasteless and non-toxic, and it is not afraid of high temperature and cold. At 300 ℃ and minus 90 ℃, it is "calm" and "looks the same" without losing its original strength and elasticity. Silicone rubber also has good electrical insulation, oxygen resistance, aging resistance, light resistance, aging resistance, mildew resistance, chemical stability, etc. Because of these excellent properties, silicone rubber has been widely used in modern medicine.

Medical silica gel is a kind of biomaterial widely used in cosmetic surgery, with mature technology, good biocompatibility, no irritation, non-toxic, no allergic reaction to human tissues, and few body rejection reactions; It has good physical and chemical properties. It can keep its original elasticity and softness in contact with body fluids and tissues without being degraded. It is a fairly stable inert substance. It can withstand high temperature and can be sterilized. It is easy to process and shape, and is a good thing for easy processing and carving.

From the perspective of characteristics, silicone rubber has heat resistance, cold resistance, non-toxic, biological aging resistance, physiological inertia, minimal response to human tissues, no foreign body reaction even after implantation into human tissues, no inflammation to surrounding tissues, and good physical and mechanical properties.

In terms of performance and stability, silica gel is an amorphous substance, and its chemical formula is mSiO2. nH2O. It is insoluble in water and any solvent, non-toxic and tasteless, with stable chemical properties, and does not react with any substance except strong base and hydrofluoric acid. From the perspective of hydrophobicity, this is a problem that has always been wanted to solve in the medical field, because this characteristic of silica gel makes silica gel objects implanted in the human body feel foreign bodies and make people feel uncomfortable, so everything is always a double-edged sword. There is no harm without benefit. Because of the hydrophobicity of silica gel, very little water can be retained on the surface of silica gel, and almost all of it will be evaporated, which enhances its antibacterial characteristics, Because there is no water, most bacteria do not have a living environment. Ensuring a dry surface also ensures the antibacterial properties. Compared with softness, the softness of silica gel is due to its good physical and chemical properties. It can maintain its original elasticity and softness in contact with body fluids and tissues. In terms of tactility, the stimulation to the skin will be much smaller.

So according to the current trend, silica gel has become a symbol of high-tech in the beauty industry. It is not limited to a certain product, but more fields will apply the characteristics of silica gel to the extreme, leading to a new authoritative technology in the beauty industry.
