Sodium Lactate
Category: Humectant
Known For: Skin hydration, balancing skins pH
Natural Origin: Sodium lactate is derived from lactic acid, which can be found naturally in various sources such as milk, fruits, and vegetables. Lactic acid is produced through the fermentation of sugars by bacteria, particularly Lactobacillus species. In the case of sodium lactate, lactic acid undergoes a neutralization reaction with sodium hydroxide, resulting in the formation of sodium lactate.
Commercially, sodium lactate is often produced through the fermentation of carbohydrates, such as corn or sugar beets, by lactic acid bacteria. The lactic acid produced is then chemically neutralized with sodium hydroxide to form sodium lactate. This process yields a stable and water-soluble compound that can be used in various applications, including food preservation, pharmaceuticals, and skincare.
WHY WE LOVE IT
Moisturizing: Sodium lactate is a humectant, which means it attracts and retains moisture in the skin. This property helps to hydrate the skin, keeping it soft and supple.
Exfoliation: Sodium lactate also has mild exfoliating properties. It helps to gently slough off dead skin cells, promoting smoother and more radiant skin.
pH Balancing: Sodium lactate helps to regulate the pH of skincare products and the skin itself. Maintaining the skin’s natural pH balance is essential for healthy skin function and can help prevent issues like dryness, irritation, and acne.
Skin Barrier Support: By moisturizing and exfoliating the skin, sodium lactate can help strengthen the skin’s natural barrier function. This can improve the skin’s ability to retain moisture and protect against environmental stressors.
Anti-aging: Some research suggests that sodium lactate may have anti-aging properties. It can help reduce the appearance of fine lines and wrinkles by hydrating the skin and promoting cell turnover.
