Cellulose Ether for Hand Soap HEC and selected cellulose ether solutions for viscosity control, smooth texture, suspension stability, stable dispensing, and formulation consistency in hand soap systems.

HEC (Hydroxyethyl Cellulose) is the most commonly used cellulose ether in hand soap formulations. It provides viscosity control, smooth texture, suspension stability, and formulation consistency in liquid hand soap, gel hand soap, moisturizing hand wash, pearl hand soap, and other water-based hand cleansing systems. Selected HPMC and CMC grades may also be considered in customized hand soap formulations.

HEC improves product viscosity and body, creates smooth and uniform texture, supports reliable pump and bottle dispensing behavior, stabilizes suspended ingredients such as pearlizing agents and botanical particles, and helps maintain stable viscosity during storage. It is the primary non-ionic thickener used in water-based hand soap systems.

Cellulose ether primarily supports viscosity and texture in hand soap. Foam performance depends mainly on the surfactant system, foam boosters, water quality, and overall formulation design. HEC is selected to provide viscosity support without significantly disrupting the foam profile, but compatibility testing is always recommended.

Yes. Selected HEC grades may be used in clear hand soap formulations. However, final clarity depends on the surfactant system, salt level, fragrance, preservatives, polymer grade, and processing conditions. Compatibility testing under the specific formulation conditions is always recommended before finalizing the grade selection.

Yes, but foam hand soap requires low viscosity for compatibility with foam pump dispensers. Low viscosity HEC grades at low dosage levels should be tested to confirm that the product flows properly through the foam pump while maintaining adequate stability and suspension performance.

Dosage typically ranges from 0.05% to 1.2% by weight depending on hand soap type, target viscosity, surfactant system, and packaging format. Foam hand soap uses the lowest dosage range (0.05%–0.3%) due to foam pump viscosity requirements, while gel hand soap may use up to 1.2% for higher body and gel texture.

Viscosity loss in hand soap during storage may be caused by surfactant incompatibility, electrolyte level changes, pH drift, temperature fluctuations, fragrance components, preservative interactions, poor initial hydration of the cellulose ether, or selection of an unsuitable grade. A systematic compatibility and stability testing program is recommended to identify and address the root cause.

Start by defining your hand soap type, surfactant system, target viscosity, salt response, pH range, clarity requirements, moisturizing system, packaging format, suspension needs, and storage conditions. LANDERCOLL can recommend suitable HEC or selected cellulose ether grades for testing based on your specific formulation requirements.
