Description

Peg-40 Sorbitan Lanolate is a nonionic surfactant derived from the ethoxylation of sorbitan esters of lanolin fatty acids. This versatile compound is valued for its excellent emulsifying, solubilizing, and conditioning properties, making it a key ingredient in formulations requiring mildness and stability. It is primarily used by manufacturers in the personal care, cosmetics, and pharmaceutical industries to create stable emulsions and enhance the sensory profile of creams, lotions, and hair care products.

Application

• Primary Emulsifier in oil-in-water (O/W) creams, lotions, and conditioners for cosmetics and personal care.
• Solubilizing Agent for fragrances, essential oils, and lipophilic active ingredients in clear aqueous systems.
• Skin Conditioning Agent that imparts a soft, smooth feel and improves moisturization in skincare formulations.
• Hair Care Additive providing detangling, conditioning, and shine-enhancing effects in shampoos and conditioners.
• Pharmaceutical Excipient used in topical ointments and creams as a non-irritating emulsifier and stabilizer.
• Formulation Aid in sun care products to improve the dispersion of UV filters and overall product stability.

Quality Control

Our Peg-40 Sorbitan Lanolate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets consistent specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as saponification value, hydroxyl value, and water content are available upon request. Our quality commitment supports compliance for use in cosmetic and topical pharmaceutical applications.

Storage

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