Do you really think silicone oil was no problem at all?

Silicone, Chinese often called silicone, Taiwan compatriots will be translated into dimethicone or silicone (which is the English pronunciation literally). The commonly called silicone oil is known for silicone products in part. Specifically, silicone products include polydimethylsiloxane (PDMS, wide range of applications), cyclic polydimethylsiloxane (such as D4, D5, D6), emulsified oil (shampoo used) This is often referred to as three silicone oil. Another silicone waxes, silicone elastomer silicone products. Although not very scientific, but for convenience, and the words density reasons (no explanation), the following article will unify these silicone products called silicone oil.

Silicone first developed for military purposes at the time of the Second World War. Application of silicone oil in the cosmetics industry also has several decades of history, silicone oil as early as last year 1970 applied to shampoo and deodorant antiperspirant products. After decades of development, in cosmetics or personal care products wide range of applications, particularly skin care products, make-up products using silicone. So widely used silicone products (hereinafter replaced with silicone oil), whether it is human security?

The special properties of the organic silicon
General structure can be launched from the physical and chemical properties. But here, no specific analysis of the chemical structure of silicone oil, consumers need to know that. So, simply look at the nature of silicone concept: the structure is very stable and difficult to degrade, the reaction becomes difficult to occur under normal conditions and other substances. Meanwhile bond between the flexible, it is easy to move, low surface tension, so smooth is the most common in nature. It also has a gas-permeable but waterproof. All walks of life it is an indispensable material.

Silicone oil for human safety
The current study suggests that polydimethylsiloxane (PDMS) is not substantially absorbed by human skin and the gastrointestinal, almost no acute toxicity, skin almost no stimulating effect on the eye irritation, can cause mild conjunctival Red inflammation or meningitis. No evidence of teratogenic polydimethylsiloxane, carcinogenicity and genotoxicity. Reason to believe, PDMS under the existing normal use, will not pose a health hazard.
The silicone oil causes hair loss statement, nor rigorous. After using shampoo cause hair loss, a phenomenon indeed, but the cause is likely to be a preservative, flavor may be, there may be other surfactants, silicone oil is only a possibility. If one day you use the A-branded products hair loss, for the same brand with the B-containing silicone not hair after shampoo, do you think is the cause of silicone it? On the contrary, my personal experience is that the use of some shampoos containing silicone oil is no problem, but the use of a section of the country after no silicone shampoo hair brush to drop.

It is often reported that silicone oil lead to hair loss, there is no scientific basis. Silicone containing shampoo cause hair loss, you need to consider is the problem of the product, rather than make a component inside - silicone oil as a scapegoat.

While the above are talking about the safety of silicone, but this does not mean that silicone is not 100% peace of mind security concerns cosmetic ingredients.

Impurities affect the safety of silicone oil
Like with a lot of raw materials, in a variety of silicone products, many are not completely 100% pure substances, there are some impurities in it. There is a notable impurity D4 (add, D4 is ring four polydimethylsiloxane abbreviation, D5, D6 infer). D4 is a synthesis of these silicone monomers, formed by ring-opening polymerization of various kinds of organosilicon compounds. However, in the synthesis of various types of silicone oil in the production process, it is difficult to D4 100% completely reacted, so there will be some residual D4 of silicone products (D4 chemical structure as shown below).

D4 have any effect on the human body do? As a cyclic silicone oil, which is highly volatile, easily inhaled. According to the report D4 may affect human reproductive capacity, but there is no long-term study data can be 100 percent support this conclusion. At present, the cosmetics industry has been in action, Europe for silicone and D4 conduct further safety assessment. Major cosmetics companies will in some silicone raw materials required to provide residual amount of D4, D4 and raw materials for the remaining standard control. Some content may D4 silicone products up to 1%, 0.1% or less if the control or less, potential security problems arising will be much less.

Summary of silicone security:
In general, silicone itself is safe, harmless. However, residual products D4, there may be a potential safety problem.

Which production in containing D4?
D4 is the residual impurities, not on the ingredient list. But in skin care products, shampoo, hair conditioner, make-up products are likely to have minimal residual, and different silicone oil (silicone) is not the same number of residual D4. But whether trace residues can cause human health problems, which are not necessarily. But is always better, sight as SLES in dioxane.

Silicone oils and cosmetics industry development:
On behalf of the technical sophistication of the last century in the late 1960s Clinique butter, at that time the product inside has not added oil, but now look at other products Clinique, the silicone oil is a lot a lot to add, in fact, we can see that silicone oil It decades is to promote the development of the cosmetics industry.
But in the long run, the silicone oil for use in cosmetics may slowly reduce (if natural cosmetics can be the dominant words). A well-known supplier of silicone 已把 main business of silicone oil on industrial applications, and not in the cosmetics industry. For one thing, the amount of silicone oil used in the cosmetics industry is less than the amount of industrial uses, and secondly also out of consideration for human safety and consumer awareness for the safety of cosmetics, as well as a little as a synthetic nature itself does not exist The substance, its impact on the environment, but also among the factors to be considered, after the impact of silicone on aquatic organisms, self-degradation and other issues in foreign countries there are people clamoring clamor.
