Product Description
Sodium Lauroyl Lactylate SLL (CAS 13557-75-0) Cosmetic Emulsifier
Product Introduction
Sodium Lauroyl Lactylate (SLL) is a versatile, high-performance anionic surfactant and emulsifier synthesized from renewable resources like lactic acid and lauric acid. Esteemed for its exceptional emulsifying power and skin-friendly properties, it is a cornerstone ingredient for creating stable, luxurious, and elegant personal care formulations. SLL is particularly effective in stabilizing oil-in-water (O/W) emulsions, imparting a rich, velvety feel, and enhancing the moisturizing effect on the skin, making it a preferred choice for modern creams, lotions, and cleansing products.

Product Functions
- Primary Emulsifier: Forms stable, fine oil-in-water (O/W) emulsions with a silky texture.
- Stabilizer & Co-Emulsifier: Boosts the stability of emulsions against heat, aging, and pH changes, often reducing the need for other emulsifiers.
- Surfactant & Cleansing Agent: Provides mild foaming and cleansing properties, ideal for wash-off products.
- Skin Conditioning Agent: Imparts a soft, smooth, and well-moisturized feel to the skin without greasiness.
- Viscosity Modifier: Helps build and control the viscosity and rheology of formulations.
- Opacifying Agent: Contributes to the pearlescent or opaque appearance of products.
Application Areas
- Skin Care: Moisturizing creams, lotions, anti-aging serums, sunscreens, and facial cleansers.
- Hair Care: Conditioners, shampoos (for creamy consistency), and hair styling gels.
- Color Cosmetics: Foundations, BB creams, liquid makeups, and mascaras where stable pigmentation is key.
- Baby Products: Gentle creams and lotions due to its mildness.
- Food Industry (Food Grade): Used as an emulsifier and stabilizer in certain food products (subject to grade and regulation).
Manufacturing Process
Our Sodium Lauroyl Lactylate is produced through a controlled esterification process. Lactic acid is first condensed to form polylactic acid, which then reacts with lauric acid (sourced from coconut or palm kernel oil) to form lauroyl lactylic acid. This intermediate is subsequently neutralized with high-purity sodium hydroxide or sodium carbonate to yield the final product, Sodium Lauroyl Lactylate. The process is meticulously monitored to ensure consistent composition, purity, and performance.

FAQ (Frequently Asked Questions)
Q1: Is Sodium Lauroyl Lactylate natural?
A: It is considered naturally-derived, as it is synthesized from natural building blocks like lactic acid and vegetable-derived lauric acid. It is often used in formulations marketed as "natural" or "green."
Q2: Is it safe for sensitive skin?
A: Yes, Sodium Lauroyl Lactylate is known for its mildness and is generally well-tolerated, making it suitable for a wide range of skin types, including sensitive skin.
Q3: Can it be used as a sole emulsifier?
A: Yes, it is a powerful primary emulsifier effective on its own. It is also frequently used as a co-emulsifier to enhance the stability and texture of systems based on other emulsifiers.
Q4: What is the typical usage rate?
A: Usage rates typically range from 0.5% to 3% in the final formulation, depending on the application and the type of emulsion required.
Q5: How does it compare to other emulsifiers like Glyceryl Stearate?
A: While both are excellent emulsifiers, SLL often provides a lighter, less greasy feel and enhances the moisturizing sensation on the skin more effectively than traditional glyceryl stearate-based systems.
Q6: Do you offer sample quantities?
A: Yes, we provide samples for R&D and evaluation purposes so you can test its performance in your specific formulations.
