The use of silicone in cosmetics first started in 1950 with the hand cream produced by Dow Corning. This product has an excellent effect on protecting the skin, thus attracting people's attention to silicone oil cosmetics.

It was not until the 1980s that silicone surfactants developed rapidly and comprehensively on a large scale. This type of surfactant has many unique advantages, such as low surface tension, good wetting and spreading, strong thermal stability, large emulsifying effect, good compatibility, and foaming, foam stabilization and foam suppression. Non-toxic and no side effects, it has been widely used in all walks of life, and has also become a widely used additive in cosmetics.

Use silicone oil instead of perchloroethylene as the dry cleaning solvent. Green Earth's solvent is D5. When used for dry cleaning, Green Earth's solvent has a lower solubility for mineral oils and greases than for petroleum; however, the product's very low surface tension means it can be very Runs through and "flushes" away oily stains quickly. According to Green Earth, the benefits of the solvent for dry cleaning include: no pigment penetration between fibers of different colors; fibers do not shrink; buttons, trimming and decorative metal sheets and other intricate garment accessories do not require special treatment; cleaning After that, no residual odor is left on the fibers.

Polyether-modified silicone defoamer is a new type of high-efficiency defoamer that organically combines the advantages of polyether with strong anti-foaming ability and dimethyl silicone oil with strong hydrophobicity and rapid foam breaking. It has the characteristics of low surface tension, rapid defoaming, long foam suppression time, low cost, less usage, and wide application.

In the molecule of the silicone ether copolymer, the siloxane segment is a lipophilic group, and the polyether segment is a hydrophilic group. In the polyether segment, the polyethylene oxide chain can provide hydrophilicity and foaming, and the polypropylene oxide chain can provide hydrophobicity and permeability, which has a strong effect on reducing surface tension. Adjusting the molar mass of the siloxane segment in the copolymer can make the copolymer accentuate or weaken the properties of silicone; similarly, changing the molar mass of the polyether segment can increase or decrease the proportion of silicone in the molecule, which affects the performance of the copolymer. will have an impact.

From an optical point of view, covering a smooth, highly reflective solid surface with a film-forming substance with a low refractive index will weaken the surface's reflection of light. Applying this type of finish to the surface of colored fabrics will increase the apparent depth of the fabric without adding dye. The deepening effect of silicone on fabrics has a lot to do with its own refractive index and structure. Generally, the refractive index of silicone oil is 1.400 ~ 1.410 and can form a smooth and uniform film on the fiber surface. The deepening effect of the silicone oil is good, among which the amino hydroxyl modified silicone oil has the best deepening effect; for the amino silicone oil, increasing the ammonia value is not conducive to improving the deepening effect; the addition of a crosslinking agent is not conducive to the deepening; for self-emulsifying silicone oil, Darkening works best when no emulsifier is added.
