Description

Cetyl Hydroxyethylcellulose is a non-ionic, water-soluble cellulose ether derivative, chemically modified with both cetyl and hydroxyethyl groups. This unique modification provides exceptional thickening, stabilizing, and film-forming properties, particularly in hydrophobic or oil-based systems where standard cellulose ethers may underperform. It is a critical functional additive for formulators in the personal care, cosmetics, and pharmaceutical industries seeking to enhance texture, stability, and sensory appeal.

Application

• As a primary thickener and rheology modifier in oil-in-water (O/W) emulsions for creams and lotions.
• Stabilizing agent in hair care products such as conditioners, styling gels, and mousses to improve consistency and deposition.
• Film-forming polymer in color cosmetics, including mascara, eyeliners, and foundations, for enhanced wear and water resistance.
• Viscosity enhancer and suspending agent in sunscreen formulations and protective skin care products.
• Used in topical pharmaceutical preparations as a base to control drug release and improve application properties.
• Stabilizer for household and industrial cleaning products where compatibility with surfactants and salts is required.

Quality Control

Our Cetyl Hydroxyethylcellulose is manufactured under a strict quality management system. Each batch is tested against rigorous in-house specifications to ensure consistent performance in thickening, clarity, and solubility. While not typically USP/NF or EP grade, our quality protocols are designed to meet the high standards of the cosmetic and personal care industries. A comprehensive Certificate of Analysis (COA) detailing key parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect flow properties and performance.
