Will cosmetics freeze in the weather of MINUS 16 degrees?

Cosmetics will freeze when stored at-16 degrees for a long time, and skin care products will easily freeze and crack when stored in cold places. After thawing, oil-water separation will occur, which will thicken and harden some of them and irritate the skin.

In the process of inspection, the product will pass the minimum test of MINUS 15 degrees to ensure the stability of the product. Nevertheless, cosmetics still have the most suitable storage temperature. Above or below this temperature will accelerate the deterioration time of the product, so just use it up as soon as possible.

The moisture in skin care products was originally combined with nutrition, but now it is frozen into ice, and it can't be combined by itself after melting. The moisturizing effect should be ok, but the hydration may be worse. Don't use it if it is a suggestion of whitening, because the ingredients of whitening things are unstable.

Precautions for preserving skin care products:

1, thermal protection

Skin care products are not suitable for storage in places with too high temperature. Because of the high temperature, it is not only easy to volatilize the water in skin care products and dry the cosmetic cream, but also easy to separate the oil and water in the cream and deteriorate. Therefore, in hot summer, don't put too many skin care products in your handbag.

Step 2 protect yourself from the sun

Skin care products should not be stored in direct sunlight or light, because when skin care products are exposed to direct sunlight or light, water will evaporate, some ingredients will lose their efficacy, and even chemical changes will occur, reducing their efficacy. And don't choose the sample put in the cabinet when buying, because the lamp in the cabinet is easy to deteriorate after long-term irradiation.

3, antifreeze

Skin care products are easy to freeze and crack when stored in cold places, and oil-water separation will occur after thawing, which will thicken and harden some of them and irritate the skin. Choose to use the refrigerator to keep fresh at a constant temperature, but once it is put in the refrigerator, it should not be taken out frequently, because the temperature difference changes too much, which may lead to the change of product state and even affect the efficacy of the product.

4. Moisture-proof

Some skin care products contain a lot of protein and honey, which are easy to get moldy after getting wet. Some are packed in glass bottles with iron lids. The iron cover is easy to rust, corrode cosmetics and deteriorate after being wetted.

5. Pollution prevention and control

Although preservatives have been added to skin care products to prevent the products from being contaminated and deteriorated, it is still impossible to prevent them from happening. If there are bacteria in it, it will harm the skin. Therefore, skin care products must be tightened in time after use to prevent bacteria from invading and multiplying. In addition, once skin care products are used, such as creams and lotions, they can't be put back in the bottle to avoid pollution.
