Sodium lactate, known as the "gentle protector" in the realm of skin moisturizing, hails from the natural lactic acid family. It carries the mild qualities of sodium and finds its way into creams, lotions, and hair care products to bring moisture to dry skin.
What is Sodium Lactate?
Sodium lactate is an organic acid salt with the chemical formula C3H5NaO3. It is typically produced by neutralizing lactic acid (a naturally occurring organic acid found in yogurt and certain fruits). In the personal care products industry, sodium lactate is widely used as a multifunctional ingredient.
Applications of Sodium Lactate
Skincare Products: Sodium lactate is commonly used in creams, lotions, and serums as an ingredient to moisturize and soften the skin.
Cleansing Products: In cleansing products, sodium lactate can help regulate the pH of the product, reducing the tight feeling of the skin after cleansing.
Sunscreen Products: In sunscreen, sodium lactate can act as a stabilizer while also providing moisturizing effects.
Hair Care Products: Sodium lactate in hair products can effectively help repair damaged hair, adding shine and smoothness. Since lactic acid is a natural component of hair, sodium lactate can act as a pH regulator in hair care products. It is milder compared to other pH regulators, making the hair slightly acidic, which improves its condition and makes it easier to comb.
Functions of Sodium Lactate
Humectant: Sodium lactate is an excellent moisturizing ingredient that can absorb moisture from the air. Thus, sodium lactate in hair products can keep the scalp moist and reduce water loss.
pH Regulator: Sodium lactate can adjust the acidity and alkalinity of products, making them closer to the skin's natural pH. Therefore, sodium lactate in hair products can reduce irritation to the scalp.
Skin Softener: Sodium lactate can also soften the skin, helping to improve skin texture and elasticity.
