Silicone oils are known to be found in shampoos and cosmetics. But few people know that silicone oils are also used in sunscreen and skin care products. This is mainly because of the characteristics of silicone oil itself.
Because silicone oils are silky and can't be replaced by many other oils, they're used a lot in one product -- the sunscreen everyone wears in the summer.
Most girls know sunscreen, because of the sunscreen inside, a lot of times when sweating, you can rub mud on your face, but if there is silicone oil, a lot of trouble will not exist.




Take the very famous Ann XX for example, it added many kinds of silicone oil, about seven or eight kinds, including regulating the skin sense of silicone oil, silicone oil treatment of physical sunscreen, silicone oil emulsifier, film forming agent and even sunscreen itself (polysiloxane -15), is also a silicone oil structure in it, can be called the template of silicone oil.


Such as adjust the effect of skin IOTA polydimethylsiloxane 201 and D5 ring IOTA D5, the former can achieve very smooth feeling, while the latter contains certain volatile, finished then if nothing, almost no residual, they all can reduce oily feeling of all kinds of sunscreen, almost impossible to replace.
In addition, due to the unique bond angles and bond lengths of silicone oil molecules, oxygen and water vapor can pass through it (even the relatively heavy 201-350 silicone oils), so sweat on the skin can evaporate freely without creating a sultry sensation, which is exactly what sunscreen needs.
In addition, the permeability of silicone oil has been widely used in clinical medicine. Some wound dressings, for example, or gels that aid in scar healing, are made of silicone oil and silicone elastomers. They are good for wound healing because they hold water and are not as airtight as mineral oils, allowing water vapor to pass through. Silicone oil added to sensitive muscles or children's skin care products also uses this principle to speed up barrier repair. So as to achieve skin care and recovery.
