1,2-pentanediol, chemical formula C5H12O2, is a colorless and transparent liquid that is stable at room temperature, not easily oxidized, has low irritation to the eyes and skin, has low viscosity, and good water solubility.
1,2-pentanediol is a type of ortho alkyl diol, which is a straight chain alkyl diol with distinct polarity and non-polar properties, making it different from other diols; It can capture water molecules through hydrophilic groups and exert moisturizing effects, while also having the ability to inhibit bacteria and fungi. It can be used as a solvent, preservative, and moisturizer for many cosmetic ingredients.
Moisturizing effect
1. Moisture absorption: 1,2-pentanediol can absorb moisture from the air and help keep the skin moist.
2. Water locking: It can form a protective film on the surface of the skin, preventing water evaporation and enhancing moisturizing effect.
3. Moisturizing agent: improves the texture of the product, making the skin softer and smoother.
4. Other: It can also be used in combination with other moisturizing agents such as glycerin, hyaluronic acid, etc. to improve moisturizing effect.
Anti corrosion effect
1. Antibacterial: 1,2-pentanediol can inhibit the growth of bacteria and fungi, extending the shelf life of products.
2. Synergistic effect: When used in combination with other preservatives, it can enhance the overall anti-corrosion effect and reduce the amount of a single preservative.
Solubilization effect
1,2-pentanediol can dissolve some water-insoluble ingredients such as spices, pigments, etc. in the formula, making the product more uniform and stable. It can also improve the permeability and absorption of cosmetics, making the product easier to be absorbed and utilized by the skin.
Security
1. Low irritation: gentle on the skin, suitable for use on sensitive skin.
