Quick Answer
Quick AnswerHEC (Hydroxyethyl Cellulose) is the primary cellulose ether used in dishwashing liquid. It functions as a non-ionic thickener and rheology modifier that controls product viscosity, builds smooth texture, supports stable pouring behavior, and maintains formulation consistency throughout storage.

Dishwashing liquid — also called hand dishwashing liquid or dish soap — is a water-based detergent used to clean dishes, cookware, glassware, kitchen tools, and food-contact surfaces before rinsing. It is one of the most widely used household cleaning products globally, and its formulation must balance grease removal, foam performance, mildness, viscosity, appearance, and storage stability simultaneously.
Éter celulózy is used in dishwashing liquid as a rheology and viscosity modifier. It helps improve product texture, flow behavior, suspension stability, and appearance while supporting a more consistent and consumer-friendly user experience. Among available cellulose ether types, HEC (hydroxyethylcelulóza) is the most widely used grade in dishwashing liquid systems due to its non-ionic character, broad surfactant compatibility, and smooth thickening profile.

HEC is the primary choice for dishwashing liquid viscosity and texture. CMC supports selected formulations where suspension is required. HPMC may be considered for specialty and gel-type dish soap systems.
Primary · Non-Ionic · HEC
Non-ionic cellulose ether for thickening, viscosity control, smooth flow, and formulation stability.
HEC is the most commonly used cellulose ether in dishwashing liquid formulations. As a non-ionic, water-soluble polymer, HEC is compatible with a broad range of anionic, non-ionic, and amphoteric surfactant systems typically used in hand dishwashing products. It hydrates readily in water and builds viscosity efficiently at low dosage levels, making it a cost-effective thickening solution for both economy and premium dishwashing liquid formats.
Anionic · CMC · Selected Systems
Cellulose ether option for suspension support, product body, and selected formulation stability needs.
CMC may be used in selected dishwashing liquid or household cleaning formulations where suspension support, viscosity contribution, or formulation consistency is required. Its use is more application-specific than HEC in dishwashing systems. Important: CMC is an anionic polymer; compatibility with surfactant system, salt level, pH, fragrance, preservative, and active matter content must be confirmed through formulation testing before production scale-up.
Specialty · HPMC · Gel Systems
Selected cellulose ether for specialty thickening, rheology control, and customized product texture.
HPMC may be considered in specialty dishwashing liquids, gel-type dish soaps, or customized household cleaning products where special rheology behavior, water-soluble polymer characteristics, or texture adjustment is required. Final use must be validated through formulation testing, as HPMC performance depends strongly on surfactant composition, electrolyte level, solvent system, pH, and production process conditions.

Cellulose ether influences viscosity development, product texture, pouring behavior, suspension stability, foam-compatible rheology, and long-term storage performance in water-based dishwashing liquid systems.
HEC helps adjust dishwashing liquid viscosity to a defined target range and supports a balanced product body. Proper viscosity control makes the product look more stable, dose more easily, and feel more satisfying during consumer use. Without adequate viscosity control, dishwashing liquid may appear thin, drip uncontrollably, or fail to meet quality specifications.
A smooth and uniform liquid texture is one of the most important sensory quality indicators in dishwashing liquid. Cellulose ether helps create a more consistent flow profile, reduces watery or uneven product feel, and supports a more premium consumer experience at the point of use.
Dishwashing liquid should pour cleanly and consistently from the bottle — not too thin (dripping, splashing) and not too stringy or slow. The right cellulose ether grade and dosage help balance thickness and flow for controlled, consumer-friendly dispensing.
Some dishwashing liquids contain opacifiers, pearlizing agents, fragrance droplets, or decorative visual particles that require suspension support. Cellulose ether can help maintain uniform distribution and reduce settling or phase separation during storage.
Cellulose ether primarily controls viscosity and texture rather than foam performance. However, the rheology profile should be designed so the product remains pleasant to use during washing — not so thick that it is difficult to lather, and not so thin that it drips away before foaming.
A suitable cellulose ether grade helps maintain product appearance and viscosity during storage when properly matched with the surfactant system, salt level, pH, fragrance, and preservative system — critical for extended shelf-life and temperature-variable distribution.
When dishwashing liquid fails viscosity, texture, or stability targets, cellulose ether grade, dosage, hydration, or compatibility is often the first variable to review.
Weak thickener system or low viscosity response.
HEC supports viscosity control and product body.
Excessive polymer level or salt over-response.
Adjust cellulose ether dosage and salt level.
Unsuitable viscosity profile or excessive dosage.
Select appropriate grade and optimize dosage.
Surfactant, salt, pH, or temperature interaction.
Test grade compatibility and confirm stability.
Poor formulation balance or weak suspension.
Cellulose ether supports suspension stability.
Surfactant, fragrance, salt, or polymer incompatibility.
Confirm compatibility through systematic testing.
Poor dispersion or insufficient hydration time.
Improve addition method and mixing sequence.

Technical documentation (TDS, SDS, COA)
If your dishwashing liquid is too thin, too thick, stringy, unstable, cloudy, difficult to pour, or losing viscosity during storage, the cellulose ether grade or dosage may need to be reviewed.
LANDERCOLL can help evaluate suitable HEC, CMC, and selected cellulose ether options based on your surfactant system, salt level, pH, active matter content, clarity target, viscosity requirement, and production process.
HEC (Hydroxyethyl Cellulose) is the most commonly used cellulose ether in dishwashing liquid. It is used for viscosity control, thickening, smooth texture, and formulation stability. CMC and HPMC may be considered in selected customized or specialty dishwashing systems where specific suspension, rheology, or gel-type performance is required.
HEC improves viscosity, builds product body, creates a smooth liquid texture, supports stable pouring behavior, and helps maintain suspension of opacifiers and pearlizing agents. As a non-ionic polymer, HEC is compatible with a broad range of surfactant systems used in hand dishwashing liquid formulations.
Cellulose ether primarily supports viscosity, texture, suspension stability, and formulation consistency. Cleaning power — including grease removal and soil lifting — depends on the surfactant system, grease-cutting ingredients, water quality, temperature, and washing conditions. Cellulose ether contributes to the user experience and product stability rather than directly to cleaning chemistry.
HEC primarily affects rheology and viscosity rather than foam generation. Foam performance depends on the surfactant system, foam boosters, and co-surfactant selection. However, the rheology profile should be designed to be compatible with foam behavior during consumer use. Compatibility and consumer-use testing are recommended to confirm the overall product experience.
A common reference dosage range is 0.1%–1.2% by weight, depending on product format, viscosity target, surfactant system, salt level, and cellulose ether grade. Hand dishwashing liquid typically uses 0.2%–0.8%, while gel-type dish soaps may require up to 1.2%. Final dosage must be confirmed through viscosity testing and stability evaluation.
