Natrosol 250 HR 25/1 (30,000)

Natrosol 250 HR is a non-ionic, water-soluble polymer in the form of a white, free-flowing granular powder. Produced by reacting alkali cellulose with ethylene oxide under controlled conditions, this product is specially purified for personal care and cosmetic applications. With a minimum purity of 94.5%, Natrosol 250 HR easily dissolves in both hot and cold water, forming crystal-clear solutions .

Technical Specifications and Performance

The letter 'R' in the product name represents the retarded hydration process; this feature is a pH-sensitive coating that prevents clumping upon contact with water. Products formulated with Natrosol 250 HR exhibit pseudoplastic flow properties; this allows the product to dispense from the packaging with a thick consistency while spreading easily on skin or hair .

Application Areas

Natrosol 250 HR is widely used in the personal care and medical industries in the following areas :

• Hair conditioners
• Shaving gels and foams
• Liquid soaps
• High-salt content toothpastes
• Makeup and mascara applications
• Baby and adult wipes

Usage and Dissolution Instructions

To prepare lump-free solutions, Natrosol 250 HR should be added to stirred water at a pH of 7.0 or lower. After the particles are fully dispersed, the pH value is raised to 8.5 or higher to trigger viscosity development. The hydration time is directly dependent on the water temperature and pH level; acidic and cold water prolongs this period.
