Why does hand cream come out as water when squeezed out? How to preserve hand cream?

Have you ever encountered this problem: when the facial cleanser or hand cream at home is almost used up, why does it come out like water? Why does hand cream come out as water? Is it broken?

Why does hand cream come out as water?

There are two situations. The first is that the hand cream will stratify and turn into water. Hand cream contains a lot of oil and water, is not easy to preserve, and is prone to water and oil separation. Another situation is if there is an odor, which means that the hand cream has gone bad. When this kind of deterioration encounters high temperature, the high temperature will evaporate the moisture in the hand cream. Due to the closed environment, the evaporated moisture condenses into water droplets and also turns into water.

Can I still use hand cream if it is water after being squeezed out?

In the case of water-oil separation, the upper layer appears watery and the lower layer appears oily. If the hand cream is within its normal shelf life and does not have any odor, you can continue to use it without worrying. The spoiled ones form a lot of bad water, which are harmful to the human body. Normally, if the hand cream is placed in a low-temperature environment, it will solidify and the lotion inside will freeze together. We should not place the hand cream under high temperature, as this will cause the hand cream to directly form water after melting, because the hand cream has undergone a chemical reaction in this process and directly skipped the original state, eventually causing the hand cream to deteriorate.

How to store hand cream

1. Before using hand cream every time, wash your hands with hand sanitizer first, and then squeeze the hand cream.

2. If you are using bottled hand cream, it is best not to touch it directly with your hands. You can buy a special small spoon and use it to scoop the cream when applying. Of course, you must clean the small spoon before each use, and also need to clean it after use and keep it in a clean place.

3. After using the hand cream each time, cover the bottle cap in time. Never expose the hand cream to the air for a long time, as this will drastically shorten the use time of the hand cream.

4. Avoid storing hand cream in high temperature environment and avoid direct sunlight.

How long is the shelf life of hand cream?

2-3 years. Hand cream is a type of hand skin care product. The general shelf life of skin care products is 2-3 years. The shelf life of hand creams from different brands is also different. Therefore, the specific shelf life depends on the time indicated on the hand cream. Of course, the shelf life here is the shelf life marked on the hand cream, which refers to the shelf life of the hand cream when it is unopened. Once the hand cream is opened, the shelf life will no longer be the original number.

The shelf life of hand cream will be shortened after opening

Because the main ingredient of hand cream is oil, when the oil is opened and comes into contact with the air, it will easily absorb dust and bacteria in the air, thereby causing its composition to change. Especially hand cream with pure plant ingredients will oxidize very quickly after opening. If it is not used up within a certain period of time, the hand cream will lose its effect or directly deteriorate.

How long does it take to use up opened hand cream?

1. Tube hand cream: Common hand creams are generally in tube form. The advantage of tube hand cream is that the hand cream can be squeezed out and used without direct contact with hands, which reduces the probability of the hand cream deteriorating. If it is well stored, the shelf life after opening is 12 months.

2. Canned hand cream: In addition to tube hand cream, there is also canned hand cream. When using canned hand cream, you need to take it directly with your hands, or use other tools, but this will definitely come into contact with more bacteria and dust than tube hand cream. Therefore, after the canned hand cream is opened, the usage time will not be very long. It is best to use it up within 6 months.
