During the epidemic, a plate of eye shadow on the table turned out to be moldy and hairy! Today, let’s dig deep into the preservatives in skin care products and see if the preservatives in big-name products are reliable.
Little friends who want to read it right away can also pull it directly to the end to see the conclusion.
Not much to say, let’s look at the types of preservatives on the market first. There is nothing more detailed than this. Once a picture is done, everyone must collect it and save it for easy retrieval. Maybe one can help you avoid the risk of irritating sensitive skin.
In the picture, all kinds of preservatives are milder and milder from left to right, and the price is higher. Note that the maximum concentration of preservatives ranges from 0.1% of formaldehyde emitters to 1% of alcohols.
The first category is formaldehyde-releasing preservatives. It is not difficult to find that it kills bacteria by releasing formaldehyde. Xiaobian teaches you to recognize it at a glance ~ The names of this kind of preservatives are very easy to remember, because they are very "urine-like" and usually use urea as suffix, such as imidazolidinyl urea, DMDM hydantoin and diazolidinyl urea.
Formaldehyde-releasing preservatives are relatively irritating to the skin, and sensitive muscles should be used with caution. These preservatives are usually used in rinse-off products such as facial cleanser. Xiaobian specially searched for products with this preservative, but Xiaobian wants to declare that whether the product has the risk of acne needs to comprehensively consider the factors of product formula, technology and content. Skin care products containing anti-acne ingredients are generally not easy to be teased because they can be quickly cleaned in rinse-off products such as facial cleanser and makeup remover.
Olay used this preservative in a face-rejuvenating lotion in 2017. At present, it can’t be found in the flagship store.
In the ingredient list, green is safe, orange is medium, and red indicates risk. The higher the number, the higher the risk.
The second kind of organic halogen preservatives, chloromethyl isothiazolinone and methyl isothiazolinone, have good bactericidal effect on bacteria, yeast and mold, and are widely used in some wash-off products, such as Estee Lauder Red Pomegranate Cleanser.
The essence cream of Hailan Mystery also contains organohalogen compounds. As a luxury brand, why did Hailan Mystery choose this preservative? In fact, this cream has been developed for 12 years. As an old brand, it is troublesome to change a raw material formula or raw material dough, and these preservatives can be used normally within a reasonable concentration range if they are not very sensitive and intolerant skin.
Finally, follow Xiaobian to see polyols. This kind of preservatives is very interesting, because they belong to a non-preservative system. Obviously, how can preservatives become a non-preservative system? We can understand that it is not included in the 51 preservatives in the Technical Specification for Cosmetic Safety, but it has antiseptic effect.
For example, pentanediol, hexanediol, octanediol and phenylethanol are raw materials with antiseptic function or auxiliary antiseptic function. Many big brands like Estee Lauder’s Firming and Brightening Repair Muscle Essence, Xiansejia’s Sensitive Muscle Repair, B5 Essence, SKII Essence and Xiansejia Probiotic Water that replenish skin use this kind of antiseptic.
In the past two years, with the rise of ingredient APP, more people began to pay attention to cosmetic ingredients, but preservatives were the first to be rejected. But now we know that preservatives are essential except for vacuum disposable packaging, so it is unnecessary to talk about anti-corrosion discoloration. uu people pay attention to these explicitly prohibited preservatives, such as quaternary ammonium salt -15, propyl 4-hydroxybenzoate, isopropyl hydroxyphenyl, isobutyl hydroxyphenyl and formaldehyde-releasing preservatives with greater irritation.
To sum up, the preservatives carefully selected for sensitive muscles include formaldehyde releasers (imidazolidinyl urea, DMDM hydantoin) and parabens (methylparaben, ethylparaben, propyl 4-hydroxybenzoate, butylparaben); Organic halogen compounds are commonly used in washing agents, but they are gradually withdrawn from use with the update of formula; Alcohol preservatives were used in skincare SKII, Xianse B5 essence, Estee Lauder and Xianse probiotic water. In addition, organic acids have antiseptic effect at low PH and are not suitable for sensitive muscles.
