How Does the Walk-in Chamber Do Environmental Tests for Skin Care Products?

For women, skin care products are much more important than bags and clothes. In addition to efficacy, the skin care industry actually has relatively rigid indicators for quality, such as shelf life, storage environment, etc. There must be clear labels. If you want to understand These data must be tested in advance. The constant temperature and humidity test chamber is one of the commonly used test methods in the research and development process of skin care products.

Ⅰ. The principle of walk-in chamber for skin care products

Most skin care products have a three-year shelf life, so how did you come to this conclusion? It is impossible to observe product changes during the research and development process. At this time, the role of environmental simulation tests comes in.

The research and development of skin care products usually uses equipment such as constant temperature and humidity test chambers to carry out accelerated constant temperature tests. In a short period of time, the changes of products in a few years are simulated by accelerating the simulated temperature changes, and at the same time, the highest temperature and lowest temperature.

Ⅱ. Use the walk-in chamber to test the temperature resistance of skin care products (emulsion)

1. Heat resistance test:

(1) Equipment: constant temperature and humidity test chamber;

(2) Temperature requirements: temperature control accuracy +19℃;

(3) Test method: Put the samples into two cleaned and dried medicinal plastic bottles, tighten the lids, and put one bottle into a walk-in chamber with a pre-adjusted temperature of 48±1℃. After 48 hours, Take it out, and after returning to room temperature, visually compare it with another bottle.

(4) Inspection standard: After returning to room temperature, the paste will not appear oil-water separation phenomenon.

2. Cold resistance test:

(1) Equipment: constant temperature and humidity test chamber;

(2) Temperature requirements: temperature control accuracy 2 ℃;

(3) Test method: put the sample into two washed and dried medicinal plastic bottles, tighten the lid, and put one bottle into a walk-in chamber with a pre-adjusted temperature of -18±1℃, after 48 hours Take it out, and after returning to room temperature, visually compare it with another bottle.

(4) Judgment standard: After returning to room temperature, there is no obvious difference in properties with that before the test.
