National Medical Products Administration: It is not recommended for children to use hair dye or perm cosmetics. | Ingredients | Cosmetics

The website of the National Medical Products Administration recently issued a consumption reminder for children's hair dye and perm cosmetics, and it is not recommended for children to use hair dye and perm cosmetics.

The National Medical Products Administration pointed out that currently, some parents dye or perm their children's hair to beautify their appearance in pursuit of fashion or stage performance effects. However, for children, using hair dye and perm cosmetics can bring certain safety risks.

There are three main reasons for this:

1. hair dyeing and perm cosmetics are special cosmetics with high safety risks.

In China, hair dyeing and perm cosmetics are special cosmetics, which can be produced and imported only after being registered by the State Drug Administration. Common hair dyeing cosmetics on the market generally produce pigment macromolecules that can be fixed in the hair through oxidative polymerization under the action of a dye precursor and a coupling agent under the action of a strong oxidant, thereby changing the color of the hair. Common perm cosmetics on the market generally destroy chemical bonds such as disulfide bonds in the hair through reductive ingredients, curl or stretch the hair with the help of external force, and finally repair the previously destroyed chemical bonds to set the hair, thus achieving the effect of changing the curving degree of the hair. The main functional ingredient of hair dye cosmetics is hair dye, and the main functional ingredient of perm cosmetics is perm agent, which is strictly managed in our country. In the "Cosmetics Safety Technical Specification", there are now more than 70 kinds of permitted hair dyes such as resorcinol, and commonly used perm agents such as thioglycolic acid are included in the list of restricted components, all of which have clear restrictions on use.

2. children's physiological characteristics determine the hair, perm cosmetics are not suitable for children to use

Compared with adults, children's skin has the characteristics of incomplete epidermal barrier function, immature dermal fiber structure, and imperfect secretion of epidermal lipid glands. Therefore, children's skin has weak tolerance to external stimuli and is sensitive to foreign substances. After using cosmetics, problems such as dry skin, redness, and itching may occur. Moreover, children are still at a critical stage of growth and development, and various risk factors may cause more potential adverse effects on them. In addition, children's skin stratum corneum is thin and highly hydrated, the skin connection is loose, the ratio of body surface area to body weight is large, and the skin absorption ability is strong. In addition, children's mind is not yet sound, and they are more likely to accidentally enter the eyes and enter the mouth during use. Phenomenon, causing safety risks.

Based on the physiological characteristics of children, the formula design of children's cosmetics should follow the principles of safety first, necessary efficacy, and minimalist formula. According to the Regulations on the Supervision and Administration of Children's Cosmetics, children's cosmetics refer to cosmetics that are suitable for children under the age of 12 and have cleaning, moisturizing, refreshing, and sun protection effects. According to the Classification Rules and Catalogue of Cosmetics, the efficacy claims of cosmetics for infants and young children aged 0-3 are limited to "cleaning, moisturizing, hair care, sun protection, soothing, and refreshing"; The efficacy of cosmetics used by children aged 3-12 is limited to "cleaning, makeup removal, moisturizing, beauty modification, aromatherapy, hair care, sun protection, repair, soothing, and refreshing". It can be seen that hair dye and perm cosmetics do not belong to the category of children's cosmetics, and it is not recommended for children to use hair dye and perm cosmetics.

3. the possible risks of using hair coloring and perm cosmetics for children

Due to individual differences, improper use, etc., cosmetics may cause adverse reactions, such as "contact dermatitis" caused by sensitizers or irritants ". Some hair dyes, such as p-phenylenediamine, are known to be relatively common allergens. According to the "Technical Specifications for Cosmetic Safety", product labels that use hair dyes must be marked with warnings such as "hair dyes may cause severe allergic reactions" and "not suitable for consumers under the age of 16. Some common ingredients in hair dyeing and perming products, such as hydrogen peroxide and thioglycolic acid, are relatively irritating. According to the "Cosmetic Safety Technical Specification", product labels that use these ingredients must generally be marked with corresponding warnings, such as "prevent children from grabbing" and "avoid contact with eyes. Due to the differences in the physiological characteristics of children and adults, coupled with the lack of cognitive ability, they are more likely to ignore warnings, misuse products, or accidentally enter the eye, entrance, etc., which is more likely to cause serious cosmetic adverse reactions.

Here, the National Medical Products Administration reminds parents to pay attention to the importance of beauty and safe use of makeup. It is not recommended for children to use hair dye or perm cosmetics.
