Now shampoos are beginning to promote silicone-free oil. Why do you need to add silicone oil (polydimethylsiloxane) to your skin care products?

First of all, the silicone-free shampoo that you mentioned is actually a marketing scam created by individual manufacturers. Experts from national regulatory agencies have issued a message expressing the hope that manufacturers will be able to self-discipline and avoid excessive consumption of the concept of “silicone free”. This is why the international big-name follow-up is so slow.

Silicone oil in shampoos, if used normally, does not impose an additional burden on the hair. Correspondingly, those silicone-free shampoos will also add some cationic conditioning agents to achieve a similar conditioning effect in order to achieve a similar post-washing effect.
Speaking of skin care products, silicone oil is added to skin care products for two purposes: to adjust the feeling of use and to seal skin care. Silicone oil (especially polydimethylsiloxane), due to its innate characteristics, can improve the smoothness of the skin, reduce the stickiness and enhance the pleasure of use. You don't want to be sticky on your face after using it, it's easy to get rid of it. Secondly, polydimethylsiloxane is a fairly safe and stable raw material, and it is also found in breast fillers and condom lubricants. They stay on the surface of the skin and can be used to seal off water, long-lasting moisturizing, and wind and dust proof.

So you still think that silicone oil in skin care products is superfluous?
Whether polydimethylsiloxane is safe for sunscreen products and whether pregnant women are available. I will answer in detail:
Polydimethylsiloxane is a very safe, stable and inert raw material from the structural point of view. It is used in a very wide range of fields depending on the degree of polymerization. In the field of daily life, it includes breast augmentation prosthesis and condom lubricant.

Polydimethylsiloxane is also a very widely used raw material in the field of personal care products. First of all, from a regulatory point of view, it is not a risk substance, nor a restricted ingredient. Secondly, its use in skin care products is mainly to improve the feeling of use of the product. Because it is neither hydrophilic nor lipophilic, it not only reduces the stickiness of the product, but also improves the greasy feel of the product. In the field of sun protection, it can also improve the dispersion properties of related inorganic sunscreens, thereby achieving the function of increasing the SPF value.
According to the information obtained from the authoritative information website GNPD, among the 858 sunscreen products listed in Europe and North America in the past year, the proportion of polydimethylsiloxane in the product can be ranked in the top 15 and ranked in it. The front is basically a basic component of sunscreens, antioxidants and other formulas; it is used more frequently than the sunscreen lotion.
If we change the market to the Asia-Pacific market, the frequency of use of polydimethylsiloxane is similar in the sunscreen products listed in the past year.

If we reduce the population to a more safe baby, the frequency of use of polydimethylsiloxane is similar in the 170 products.
The fear of conventional consumers may stem from the rise of two-in-one shampoos and the rise of silicone-free shampoos. For the time being, no matter whether hair care or skin care are two things, the silicone-free shampoo itself is a marketing farce. There is no scientific evidence that silicone oil, or polydimethylsiloxane, can have a negative impact on hair, and alternatives to silicone-free shampoos are no better or safer than traditional silicone oils.

So, for this ingredient, you can rest assured.
Of course, the safety of the structure does not represent the safety of the raw materials or products. The raw materials of regular large factories will have stricter control of impurities and batch stability. Regular cosmetics companies will use higher quality raw materials, and the risk factor will be much lower.
