What preservatives can be added to skin care products?
The existence of skin care preservatives is antiseptic. In the 2015 edition of the "Cosmetic Safety Technical Specifications", China also stipulates the antiseptic properties of skin care products, and the standards are also very strict. Such preservatives include:
1. Parabens
Such preservatives are well recognized, generally "hydroxyphenyl". Methylparaben, ethylparaben, propylparaben, butylparaben, isobutylparaben, etc. are common compounds. These parabens are slightly safer.
2. alcohol.
Isotopes of this type are phenoxy alcohol and benzyl alcohol. It has both solvent and preservative properties and is found in various skin care products. It is not recommended for children under the age of three.
Benzoic acid, sodium benzoate, sorbic acid/potassium sorbate, salicylic acid, etc. are more common. The damage to the skin is relatively small, but the anti-corrosion ability is relatively weak, and it is not resistant to high temperature, so other preservatives are generally compounded in skin care products.
The above three preservatives are widely used in various skin care products because of their high safety index (paraben is controversial internationally, but has not yet reached a consensus). Danghong fried chicken brands are as follows:
3.Triisothiazolinones
Such preservatives, primarily methylisothiazolinone and methylchloroisothiazolinone, are often used in combination and are commonly referred to as cassone. There is a danger of causing contact dermatitis, and friends with sensitive skin can detour. If you really want to choose, try it with a small sample first.
Fourth, formaldehyde emissions.
This type of adhesive slowly releases small amounts of free formaldehyde, which kills microorganisms. Common diseases such as: DTM hydantoin (DTMH), quaternary ammonium salt-15, bis (hydroxymethyl) imidazolidinyl urea, commonly used ingredients in the name of "urea" are almost in this category. This kind of cream is rare in the skin care products of general big brands, and most of them are used by some lesser-known brands. Pregnant women and sensitive skin should use with caution.
The safety performance of the above two preservatives is slightly lower. Generally, the preservatives of well-known brands are relatively small, but there are also some that can be seen, such as:
Regardless of the drug, most people have their sights set on harmful substances. The question goes back to the cliché that all poisons that put doses aside are hooligans. In fact, in skin care products, there are very strict standards for fatliquoring. For which fatliquors can be added, and how much? Our country has express regulations. The addition within the standard value range has little harm to the human body, and it can also be excreted through the stool.
