Cellulose Ether Solutions for Personal Care Brands HEC, HPMC & CMC for shampoo, body wash, lotion, toothpaste, and cosmetic formulations — viscosity control, texture, and stability.

HEC, HPMC, and selected CMC products may be used in personal care formulations to support viscosity control, texture, suspension stability, product body, and formulation consistency. HEC is the most commonly used grade in water-based systems such as shampoo, body wash, and facial cleanser. HPMC may be used in selected cleansing, gel, and cream formulations. CMC is used in selected oral care and toothpaste applications.

HEC helps improve viscosity, smooth texture, water-based thickening, suspension stability, and product consistency in selected personal care formulations. It is non-ionic, water-soluble, and compatible with a wide range of surfactants — suitable for shampoo, body wash, facial cleanser, hand soap, lotion, and styling products.

Yes. HPMC may be used in selected personal care products where viscosity control, product body, smooth texture, and stable flow behavior are required. It can be useful in cleansing gels, styling products, creams, and selected specialty formulations. Final compatibility should always be confirmed through testing.

Selected suitable CMC grades may be used in toothpaste to support paste structure, viscosity control, and abrasive suspension. For oral care applications, suitable compliant grades must be selected and verified to meet regulatory and safety requirements in your target market.

A common reference dosage is around 0.1%–1.5%, depending on product type, target viscosity, grade, formulation system, and sensory requirement. Lotions and creams typically use lower dosages (0.1%–0.6%), while toothpaste and styling gels may require higher levels (0.3%–1.5%). Final dosage should always be confirmed through testing.

Yes. Suitable cellulose ether grades can help improve smoothness, body, viscosity, and application feel in selected personal care systems. The specific improvement depends on grade selection, dosage, formulation system, and processing conditions.

Separation may be caused by weak structure, emulsion instability, surfactant incompatibility, insufficient thickening, pH change, electrolyte effects, or processing issues. Reviewing cellulose ether grade selection, confirming dosage through stability testing, and evaluating the complete formulation are important steps to address separation.

Define your surfactant system, target viscosity, clarity requirement, electrolyte level, fragrance, preservative, pH, sensory target, and storage stability goal. HEC is a common starting direction for shampoo and body wash. LANDERCOLL can recommend suitable HEC or HPMC grades for testing based on your formulation parameters.
