Description

α-Hydro-ω-Hydroxy-Poly(Oxyethylene)C16-C18Alkylethercitrates is a high-purity, non-ionic surfactant and emulsifier derived from ethoxylated fatty alcohols and citric acid. This compound matters for formulators seeking a biodegradable, multifunctional ingredient with excellent emulsifying, solubilizing, and skin-conditioning properties. It is primarily needed by manufacturers in the personal care, cosmetics, and pharmaceutical industries for creating stable, mild formulations such as creams, lotions, and cleansing products. Its structure offers a favorable balance between hydrophilic and lipophilic character.

Application

• Primary Emulsifier in oil-in-water (O/W) creams, lotions, and sun care products.
• Solubilizing Agent for fragrances, essential oils, and active ingredients in clear gels and solutions.
• Skin-Conditioning Base for mild facial cleansers, shower gels, and baby care formulations.
• Stabilizer and Dispersant in pharmaceutical topical preparations and cosmetic serums.
• Key Ingredient in eco-friendly and rinse-off products due to its enhanced biodegradability profile.
• Industrial Applications as a wetting and dispersing agent in specialty chemical formulations.

Quality Control

Every batch of α-Hydro-ω-Hydroxy-Poly(Oxyethylene)C16-C18Alkylethercitrates is produced and tested under a strict Quality Management System. We ensure compliance with relevant cosmetic and chemical industry standards. Comprehensive testing includes parameters for identity, assay, residual solvents, and heavy metals. A Certificate of Analysis (COA) documenting purity, physical characteristics, and compliance is provided with each shipment and is available upon request.

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/59-77°F). This material is hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent caking or hydrolysis. For long-term storage, consider using an inert atmosphere to minimize oxidation.
