Where can I test the ingredients of cosmetics

The local CDC or a larger chemical enterprise laboratory, or go to a local testing agency, the component analysis does not issue a report, and can only tell the approximate ingredient content. The following are some simple and rough test methods for the toxicity of cosmetics, the results may not be very accurate, but at least let everyone be able to distinguish when choosing cosmetics.

1. Try on the back of the hand or the root of the ear before using a cosmetic product, these two parts are the most sensitive areas of the human body, and after evenly applying, rub the silver ring at hand (other silver products can also be replaced) in the smearing area slightly, if it is black or has light black marks, it means that it contains heavy metals such as lead, and there is no need to worry.

2. Lipsticks contain lead, and when choosing lipsticks, try to find those that contain less lead, and the less the better. The same method can be used to judge: when buying lipstick, wipe a sample of lipstick on the back of your hand, and then rub it with a silver ring, and observe the color change of the lipstick while grinding, the lipstick turns black indicates that the lipstick contains lead, the darker the black, the greater the lead content.

The ingredients of the inspected cosmetics can be divided into the following 4 main types:

Functional ingredients: It is some ingredients with specific effects: such as: moisturizing, whitening and lightening spots, astringent, promoting metabolic keratin, soothing and anti-inflammatory, sunscreen, etc., the main thing we choose skin care products is to refer to these ingredients.

Preservative. The main functions of adding preservatives to skin care products are: to prevent the growth of microorganisms, to maintain the stability of skin care products, and not to deteriorate after opening the cap.

Common preservatives are: sodium dehydroacetate, benzyl alcohol, ethyl paraben, phenoxyethanol, methylparaben, buta, sodium benzoate, etc., in addition to common preservatives, the pursuit of more mild and safe skin care, now more and more safer new preservative ingredients, such as some polyols and some plant extracts with strong preservative effect. The amount of traditional preservatives can be greatly reduced.

Emulsifiers, thickeners. Emulsifiers are also called surfactants. Water and oil are usually separated when put together, and emulsifiers allow the oil droplets to be evenly dispersed in the water, or the water is distributed in the oil.

However, the emulsifier is usually unstable and requires the right amount of thickener to maintain a certain viscosity in the mixture.

You can go to the beauty salon, you can also test the ingredients of cosmetics at home, or you can take out a little essence and apply it on your wrist, wipe it with silver jewelry, if there is a black mark, there will be a metallic substance in it, which can be detected, I usually test at home when I am idle and bored, and I have been using this.

Testing Methods of Cosmetics Testing Institutions:

Cosmetics testing method 1, determination of pH value.

Cosmetics testing methods.

2. Determination of viscosity.

Cosmetics testing methods.

3. Determination of turbidity.

Cosmetics testing methods.

Fourth, the determination of relative density.

Relative density refers to the ratio of the mass of a certain volume of material to the mass of the same volume of water. It is an important performance indicator for liquid cosmetics. The method of determining relative density is usually the density meter method.

Cosmetics testing methods.

5. Determination of color stability.

Color is an important performance index of cosmetics, and the stability of color is one of the main quality problems of cosmetics. The method of color stability determination is mainly visual inspection.

Methods for the determination of vitamin E in cosmetics.

Vitamin E, also known as tocopherol, is mostly found in plant tissues, and is a derivative of 6-hydroxybenzene dihydropyran in chemical structure, and C2 on the ring has methyl groups and warp chains. Due to the different positions and numbers of methyl groups on the ring, there are A, Y, 8 tocopherols, etc.

Natural tocopherols are all D-type, while synthetic ones are D-type. Vitamin E is an oil that is stable to heat in the absence of oxygen. Both free vitamin E and its esters are highly soluble in oils and most organic solvents, insoluble in water, and have antioxidant effects.

Monotocopherol and monotocopheryl acetate are derivatives of vitamin E. It has been widely used in cosmetics as an antioxidant.

Summary. Hello dear! We'd be happy to answer your questions. Testing of cosmetic ingredients can be inquired by the following institutions: 1. National Cosmetics Quality Supervision and Testing Center. For the query of cosmetic ingredients, it is more authoritative and credible.

2. Local CDC or chemical enterprise laboratory. For cosmetics, we can only provide an approximate ingredient content, and we cannot achieve it accurately.

Detection of cosmetic ingredients to ** detection?

Hello dear! We'd be happy to answer your questions. Testing of cosmetic ingredients can be inquired from the following institutions:

1. National Cosmetics Quality Supervision and Testing Center. For the query of cosmetic ingredients, it is more authoritative and credible. 2. Local CDC or chemical enterprise laboratory.

For cosmetics, we can only provide an approximate ingredient content, and we cannot achieve it accurately. 3. Realme app. It is easy to find the ingredients, and even understand their efficacy and precision skin care, but the authority is not very strong.

Food and drug quality supervision institutes in various places can conduct laboratory tests. It is recommended that you consult with your local health and epidemic prevention department.

I hope I can help you, if you are satisfied with my service, please give a thumbs up, I wish you a happy life!

Summary. Hello dear! Cosmetic ingredient testing can be sent to the local CDC, Food and Drug Quality Supervision Institute, third-party testing laboratories and other places for testing.

The NMPA can test cosmetic ingredients. The State Food and Drug Administration, the former People's Republic of China directly under the People's Republic of China for the unified supervision and management of food safety and drug safety and effectiveness in the national production, circulation and consumption links, was established in March 2013, and its predecessor was the former State Food and Drug Administration and the Office of the Food Safety Committee.

The health and epidemic prevention departments at or above the prefectural and municipal levels are responsible for the health supervision of the production of skin care products and cosmetics within their jurisdictions, and the health and epidemic prevention departments at or above the county level are responsible for the health supervision of the sales of cosmetics in their jurisdictions.

The NMPA can test cosmetic ingredients.

The State Food and Drug Administration of the People's Republic of China (CFDA) is the direct agency directly under the comprehensive supervision and management of food safety in drugs, medical devices, cosmetics, health food and catering, and is responsible for drafting draft laws and regulations on food (including food additives and health foods, the same below) safety, drugs (including traditional Chinese medicine and ethnic medicine, the same below), medical devices and cosmetics.

Formulate the implementation measures for food administrative licensing and supervise the implementation, organize the formulation and publication of national pharmacopoeia and other drug and medical device standards, classification management systems and supervise the implementation, formulate and organize the implementation of the inspection system for the supervision and management of food, drugs, medical devices and cosmetics, and organize the investigation and punishment of major violations.

On March 22, 2013, the "State Food and Drug Administration" (SFDA) was renamed the "State Food and Drug Administration" (CFDA). This means that this newly established ministerial-level department is officially unveiled to the public, and the "Kowloon Water Control" situation of multi-headed segmented management of food safety in the past has ended.

With the change of cosmetics regulatory policies, the filing review requirements are becoming more and more stringent. The Notice on Matters Concerning the Adjustment of the Administration of Cosmetics Registration and Filing (No. 10 [2013]) issued by the State Food and Drug Administration stipulates that before an enterprise launches a product, the "product inspection report" must be filed with a cosmetics registration and filing inspection and testing institution approved by the State Food and Drug Administration. The filing and inspection of non-special-purpose cosmetics includes the inspection items specified in microorganisms, heavy metals, dioxane, free formaldehyde, asbestos, etc.

According to the product formula and characteristics, diethylene glycol, hydroquinone, phenol and other risk substances can be tested.

Cosmetics test report test items:

Total number of colonies, total number of molds and yeasts, heat-resistant coliforms, Staphylococcus aureus, Pseudomonas aeruginosa, mercury, lead, arsenic, cadmium, methanol, diumane, asbestos, free formaldehyde, sunscreen, pH.

If you want to test the ingredients of cosmetics, you can go to a larger testing institution to do a full ingredient analysis, but you can only analyze the ingredients, not the raw materials of cosmetics.

Hope it helps.

Find a testing agency to do component analysis, ** quite expensive.

For the rest, there is no way.
