The detection of solvent residues in cosmetic packaging is a scientific process that usually involves steps such as sampling, pre-processing, testing and data analysis. the following

Here is the detailed testing process:

1. Sampling

In the detection of solvent residues in cosmetic packaging, it is first necessary to collect samples of the cosmetic packaging to be tested. Depending on the search results, different samples are available

May require different processing methods. For example, for powdery samples, it is necessary to accurately weigh the sample into a centrifuge tube and add the mixed internal standard working solution and acetic acid.

Ethyl ester, ultrasonic extraction at room temperature, centrifugation, and the supernatant was taken as the sample to be tested. For oil, paste and lotion samples, precise weighing is required

Take the sample into a centrifuge tube, add the mixed internal standard working solution and saturated sodium chloride aqueous solution, disperse it ultrasonically at room temperature, add ethyl acetate, and shake to extract.

, after centrifugation, draw the supernatant as the sample to be tested. For liquid water-based samples, the sample needs to be accurately weighed into a centrifuge tube and added to the mixing medium.

Standard working solution, sodium chloride powder and ethyl acetate, shake and extract, add anhydrous sodium sulfate after centrifugation, and absorb the supernatant as the sample to be tested.

Environmentally friendly cosmetics refer to cosmetics that minimize the negative impact on the environment and protect the balance of the ecological environment during the production, use and disposal of cosmetics. This involves many aspects such as the source of raw materials, production technology, and packaging materials of cosmetics.

2. Sources of raw materials for environmentally friendly cosmetics

In the production process of cosmetics, the source of raw materials is very important. Raw materials should come from places that do not damage the ecological environment. For example, the orchid breeding center established by  in Yunnan not only improves the ecological environment, but also extracts the active ingredients of plants. In addition, the extraction process of raw materials should be as sustainable as possible, such as using green extraction technologies such as supercritical fluid extraction, enzymatic extraction, and microwave extraction.

3. Production process of environmentally friendly cosmetics

The production process of cosmetics should also pay attention to environmental protection. For example, cosmetics companies should improve their production processes, reduce the high proportion of losses in the production process, and reduce waste in upstream links1. At the same time, an energy conservation and emission reduction plan should be formulated that matches the enterprise's plan.

4. Packaging materials for environmentally friendly cosmetics

The packaging materials of cosmetics are an important factor affecting the environmental performance. Currently, common cosmetic packaging materials on the market include glass, plastic, metal and paper materials. Among them, some types of glass, plastic and metal materials have put a certain amount of pressure on the environment. Therefore, choosing green and environmentally friendly packaging materials such as degradable bioplastics, nanomaterials, smart materials and bio-based materials is a feasible solution.

5. Development trends of environmentally friendly cosmetics
