1, 2-hexadiol is a polyol, used as a solvent in cosmetics, can help moisturize and penetrate, and has antibacterial effect.

1, 2-hexanediol

1, 2-hexadiol, which has the characteristics of hydrophobicity and hydrophilicity, is often used in cosmetics and pharmaceuticals as a solvent and penetration agent, and has certain moisturizing and anti-corrosion effects.

1, 2-hexanediol, although it has an anti-corrosion effect, is not a preservative, and cannot be controlled during the use of the opening, the anti-corrosion environment after opening is very different from the environment when sealing, so the preservative-free product preservation period tends to be conservative.

1, 2-hexadiol can be combined with water in the air into a molecular film, so as to play a water-locking effect, help to maintain the water balance in the skin, so it is often added as a moisturizing ingredient in skin care products. If the skin is relatively dry, the appropriate application of cosmetics containing 1, 2-hexanediol can help relieve skin tightness, and also make the skin more moisturized. In addition, because 1, 2-hexadiol also has a certain hygroscopic property, it can also absorb water in the air, thereby reducing the loss of water on the skin surface.

However, it should be noted that although 1, 2-hexadiol itself is not irritating, if used in large quantities or with other irritating products, it may cause allergic reactions, such as local redness, itching and other uncomfortable symptoms. At this time, it is necessary to stop using the product immediately and clean the residue in time. If necessary, it is also necessary to take antihistamines as prescribed by the doctor, such as loratadine tablets and cetirizine hydrochloride capsules.

In addition, for some people with sensitive constitutions, contact with substances that may trigger allergies should be avoided as much as possible to avoid other adverse consequences. If any discomfort occurs during use, please seek medical treatment in time.

Use of cosmetics

Step 1: Solvent
The hydrophobic and hydrophilic characteristics of 1, 2-hexadiol not only dissolve well in water, but also emulsify in oily components. And the composition is mild, has antibacterial effect, can play an anti-corrosion effect. However, large amounts of use will reduce product stickiness, so the amount of use is generally about 2%.

2. Penetration AIDS

Can promote the absorption of active ingredients, but also play a role in moisturizing (not moisturizing agent).
