General Description:
Sodium lactate is the sodium salt of lactic acid, commonly found as a colorless to pale yellow, odorless liquid when in a 60% aqueous solution. It is derived from the fermentation of sugars, typically corn or beets, making it a naturally occurring substance in the body and a common ingredient in both food and cosmetic products. It is known for its humectant properties, meaning it has the ability to attract and retain moisture.
Uses in the Cosmetic Industry:
- Humectant: Sodium lactate is widely used as a humectant in cosmetic formulations. It helps to draw moisture into the skin, making it a valuable ingredient in moisturizers, lotions, and creams to keep the skin hydrated and soft.
- pH Adjuster: It acts as a pH adjuster in various cosmetic products, helping to maintain the stability and effectiveness of the formulation by keeping the pH level within a desired range.
- Moisturizing Agent: Sodium lactate is often added to skin and hair care products for its excellent moisturizing properties. It helps improve skin elasticity and smoothness and can enhance the hydration of hair.
- Preservative Enhancer: It has mild antimicrobial properties that can enhance the effectiveness of preservatives in cosmetic formulations, thus helping to prolong the shelf life of the products.
- Buffering Agent: Sodium lactate is used as a buffering agent in formulations to maintain the desired acidity or alkalinity of the product, ensuring product stability over time.
Hazards and Safety Concerns:
Sodium lactate is generally considered safe for use in cosmetic products, but there are some potential hazards and safety concerns to be aware of:
- Skin Irritation: While sodium lactate is usually well-tolerated, it can cause mild skin irritation in some individuals, particularly those with sensitive skin. Symptoms may include redness, itching, and dryness.
- Eye Irritation: Contact with the eyes can cause irritation and discomfort. It is important to avoid direct eye contact with products containing sodium lactate.
- Ingestion Risks: Although sodium lactate is used in food products and is generally safe, cosmetic products containing sodium lactate should not be ingested. Ingesting large amounts can cause gastrointestinal discomfort.
- Allergic Reactions: Rarely, individuals may experience allergic reactions to sodium lactate. Symptoms can include rash, hives, and swelling. Those with known allergies to similar compounds should use products containing sodium lactate with caution.
