Will the emulsion freeze in winter?

The emulsion can be used temporarily after freezing, but it can't keep its original shelf life for such a long time. It should be used up as soon as possible. And will not produce any chemical reaction, but the frozen skin care products will become less absorbed than before. In addition, if you want to melt, it is recommended to melt the ice cubes at room temperature, or to melt the sealed cosmetics in water at room temperature.

1, because 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.

2. Because the moisture in skin care products was originally combined with nutrition, it is frozen into ice now, and then it can't be combined by itself. The moisturizing effect should be ok, but the hydration may be worse. If it is a suggestion of whitening, don't use it, because the ingredients of whitening things are unstable, and I don't know if it will be useless. After cosmetics are frozen, the best way to deal with them is to thaw them naturally, which can avoid the destruction of nutrients contained in cosmetics to the greatest extent. Many people worry that frozen cosmetics will be separated from oil like spoiled products. There is essential difference between frozen cosmetics and cosmetic oil-water separation caused by deterioration, so cosmetics can continue to be used as long as they are naturally thawed after freezing. The reason why skin care products freeze: Look at the ingredients in the product, and the crystallizing point of each ingredient is different. For example, the most commonly used toner usually freezes when the water reaches 0 degrees, but the toner contains alcohol (a little) and needs to be cooled for three or four degrees before it freezes. The higher the concentration, the less likely it is to freeze. 1, different skin care products have different freezing points, mainly depending on the ingredients and ingredients. Different ingredients have different mixing freezing points, so there is no uniform freezing point. 2. Long-term exposure to the temperature of-16 degrees may freeze liquid skin care products and cause oil-water separation. However, skin care products will not be stored for a long time at the temperature of-16 degrees, and the indoor temperature is basically above zero. Only in the process of transportation, it will pass outdoors, but it will not be exposed to the outside, and it is protected by transport vehicles and packaging. Skin care products will not freeze unless there are extreme situations. Skin care products are more afraid of heat. Hot weather will reduce the shelf life of skin care products, and short-term low temperature will not affect skin care products.

3. The best storage temperature of skin care products is 5-65438 05℃.

4. 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.
