Description

Sodium Isostearoyl-2-Lactylate is a versatile anionic surfactant derived from isostearic acid and lactic acid. This compound is valued for its excellent emulsifying, conditioning, and solubilizing properties in both aqueous and lipid systems. It is primarily utilized by formulators in the personal care, cosmetics, and food industries seeking effective, mild, and multifunctional ingredients.

Application

• Personal Care & Cosmetics: Acts as a primary or co-emulsifier in creams, lotions, and sunscreens, providing stable oil-in-water emulsions and a smooth skin feel.
• Hair Care Products: Used in conditioners and styling aids for its antistatic and hair-conditioning benefits, improving combability and shine.
• Food Industry: Functions as an emulsifier and dough conditioner in baked goods to improve volume, texture, and shelf life.
• Pharmaceuticals: Employed as an excipient in topical formulations for its emulsifying and skin-penetration enhancing properties.
• Industrial Applications: Serves as a dispersing agent and emulsifier in lubricants, textile processing, and agrochemical formulations.

Quality Control

Our Sodium Isostearoyl-2-Lactylate is manufactured under a strict quality management system. Each batch is tested to ensure it meets specifications for identity, purity, and performance. Certificates of Analysis (COA) are provided and the product can be supplied to meet relevant standards such as FCC for food-grade applications or cosmetic-grade requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture which may affect product quality.
