Description

Pg-Hydroxyethylcellulose Lauryldimonium Chloride is a cationic-modified cellulose ether, a key ingredient for enhancing the performance and feel of personal care formulations. This specialized polymer combines the film-forming and rheological control of hydroxyethylcellulose with the substantive conditioning properties of a quaternary ammonium group. It is primarily needed by formulators in the cosmetics and hair care industries seeking to create premium-conditioning shampoos, conditioners, and skin creams with exceptional sensory attributes and long-lasting effects.

Application

• Hair Care Products: As a primary conditioning agent and viscosity builder in 2-in-1 shampoos, conditioners, hair masks, and leave-in treatments to impart softness, manageability, and reduced static.
• Skin Care & Cleansers: Used in body washes, facial cleansers, and shower gels to provide a rich, creamy lather and a smooth, conditioned after-feel without stripping the skin.
• Color Cosmetics: Functions as a film-former and stabilizer in mascaras, eyeliners, and foundations to improve wear, water resistance, and pigment dispersion.
• Shaving Preparations: Enhances the lubricity and cushion of shaving foams and gels, protecting the skin and improving razor glide.
• Topical Pharmaceutical & OTC Formulations: Employed as a substantive thickener and emulsifier in medicated creams, lotions, and anti-dandruff shampoos where controlled deposition of active ingredients is required.

Quality Control

Our Pg-Hydroxyethylcellulose Lauryldimonium Chloride is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance, including parameters such as cationic substitution degree, viscosity, and residue on ignition. While not typically USP/NF grade, production can adhere to cGMP guidelines for cosmetic and topical drug applications. Certificates of Analysis (COA) documenting purity and key specifications are available upon request.

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); keep the original container tightly sealed when not in use to prevent moisture absorption and caking.
