The difference between lactic acid and sodium lactate. When it comes to lactic acid and sodium lactate, as we all know, they can both become natural moisturizing factors. In fact, natural moisturizing factor (NMF) is a whole, which contains many components that can become natural moisturizing factors. The characteristic of natural moisturizing factors is strong hydrophilicity, which can effectively prevent water loss. Therefore, lactic acid and sodium lactate also have strong moisturizing properties. Lactic acid is an organic pantothenic acid that exists in nature and is the final product of anaerobic biological metabolism, non-toxic and harmless. Lactic acid is a water-soluble acid that is a natural moisturizing factor for the skin, with a content of 12%. It is a good acidifier for the skin and can be dissolved with sodium lactate to adjust the pH value of the skin. It has a good affinity for the skin and hair. Let's talk about sodium lactate. Sodium lactate is a great moisturizer, with a moisturizing effect twice as good as glycerol. It is a product of plant fermentation. Sodium lactate attaches to the surface of the stratum corneum and has high moisture absorption, increasing the hydration of the stratum corneum. It has efficient moisturizing performance, antibacterial properties, and can reduce the irritation of the system to the skin. It is safe and non-toxic to use. In application, lactic acid is mainly used as a conditioner and a softening agent for the skin or hair. It is an acidifier that adjusts the pH value. It is used in hair care products such as creams and lotion for skin care, shampoo and hair conditioner, as well as shaving products and detergents. Sodium lactate can be used in moisturizing and anti-aging creams, as well as in dandruff reducing shampoo products
