Sodium lactate is a natural and multifunctional ingredient that offers many benefits for various cosmetic applications. It is the sodium salt of natural L-lactic acid, which is derived by fermenting corn or sugar beet with a bacterial culture. This clear, colorless liquid has a slightly sweet-salty taste and is known for its moisturizing and humectant properties.
Sodium lactate is commonly used in soap, skincare, and hair care products to help improve the texture, viscosity, and performance of these formulations. It is a great natural alternative to synthetic chemicals, such as glycerin and propylene glycol, which can be irritable to the skin.
When added to skincare products, sodium lactate can help improve the skin's moisture retention, making it feel hydrated and soft. It also helps to enhance the skin's natural barrier function, leading to healthy-looking and protected skin. In hair care products, sodium lactate can help reduce hair breakage, and manage hair tangles and texture.
Sodium lactate can also be used as a natural preservative in cosmetic formulations due to its antimicrobial properties. It inhibits the growth of bacteria, mold, and fungus, increasing the shelf life of a cosmetic product.
Overall, sodium lactate is a versatile and natural ingredient that can benefit various cosmetic applications, including skin and hair care formulations, providing moisturizing, humectant, and preservative benefits.
