Grade ≠ Label
Different industries require different cellulose ether grades — and the difference is not just a label. A construction-grade HPMC is engineered for water retention, workability, and open time in cement-based drymix systems. A pharmaceutical-grade HPMC must meet different purity standards, documentation requirements, and functional performance criteria for tablet coating or controlled-release applications. A detergent-grade CMC is optimized for anti-redeposition and soil suspension in laundry systems, while a ceramic-grade CMC focuses on binding, green strength, and glaze stability.
That is why LANDERCOLL organizes cellulose ether products not only by product family (HPMC, HEMC/MHEC, HEC, CMC), but also by grade direction. This structure helps manufacturers, formulators, distributors, and procurement teams quickly identify which product type is most likely to fit their application, performance target, and documentation needs — without wasting time on unsuitable options.
Each grade direction is built around real formulation requirements: water retention, thickening, rheology control, film formation, suspension stability, binding, texture, process consistency, and compliance documentation.
The right cellulose ether grade depends on more than the industry name. It depends on the specific application, required viscosity range, purity level, dissolution behavior, processing method, compliance requirements, and the performance outcome you need to achieve. Use this index to jump to the grade most relevant to your work.

Paint grade cellulose ether is designed for water-based coating systems where viscosity control, rheology management, pigment suspension, leveling behavior, brushing feel, roller application performance, and long-term storage stability are critical to product quality.
LANDERCOLL paint grade products are primarily based on HEC (Hydroxyethyl Cellulose), the most widely used cellulose ether in water-based paints and architectural coatings. HEC builds stable, pseudoplastic viscosity, suspends pigments and fillers effectively, improves flow behavior, and supports smooth application — all without significantly affecting the final film appearance or color development.
In selected coating systems, HPMC or CMC may also be considered depending on formulation design, binder type, and target performance. However, for the majority of water-based paint applications, HEC remains the primary cellulose ether choice.
Detergent grade cellulose ether is used in household and industrial cleaning products where viscosity, product texture, body, stability, and user experience all contribute to market success. In a competitive home care market, the way a product pours, feels, and performs during use is as important as its cleaning effectiveness.
Different detergent formulations require different cellulose ether functions. HEC and HPMC can improve viscosity, texture, and product consistency in liquid detergents, dishwashing liquids, and surface cleaners. CMC is especially valuable in laundry detergent systems because of its well-documented anti-redeposition performance — CMC molecules adsorb onto fabric surfaces and help prevent loosened soil particles from redepositing during the wash cycle.

Food grade cellulose ether is used in food manufacturing systems where texture, viscosity, stabilization, water binding, suspension, mouthfeel, and processing consistency are important performance criteria. Food applications demand not only functional performance but also suitable compliant grades with appropriate documentation for the target market.
LANDERCOLL food grade product direction primarily includes food-grade CMC and suitable food-grade HPMC. CMC — also known as cellulose gum in food labeling — is one of the most widely used hydrocolloids in the food industry. It is used for thickening, stabilization, water management, and texture control across a broad range of food categories. Suitable food-grade HPMC may also be used in selected food systems for film formation, thickening, stabilization, and structure support — particularly in applications where thermal gelation behavior is beneficial.
Food applications require suitable compliant grades and must be reviewed according to the regulations of the target market (such as FDA, EU food additive regulations, or local food safety standards). Not every cellulose ether grade is suitable for food use.

Demanding conditions — elevated temperatures, high salinity, significant mechanical shear. Grade selection must match.
Oilfield grade cellulose ether is used in fluid systems where viscosity control, suspension, fluid-loss reduction, rheology management, mud stability, and process reliability are critical to drilling and completion operations. These applications often operate under demanding conditions — including elevated temperatures, high salinity, and significant mechanical shear — so product selection must carefully consider the fluid system design, salinity level, temperature range, shear conditions, and target performance specifications.
LANDERCOLL oilfield grade product direction primarily includes CMC and HEC. CMC is widely used in water-based drilling fluids and completion fluids to support viscosity building, filtration control, and mud stability. HEC can also support viscosity and suspension in selected oilfield and industrial fluid systems, particularly where non-ionic behavior is preferred.
Tile Body
Glaze
ExtrusãoCeramic grade cellulose ether is used in ceramic production processes where binding, plasticity, suspension stability, green strength, shaping stability, and process consistency are important. In ceramic manufacturing, the performance of functional additives during forming, drying, and pre-firing stages directly affects the quality and yield of the final ceramic product.
LANDERCOLL ceramic grade product direction primarily includes CMC, which is widely used as a binder, suspension stabilizer, and process aid in ceramic systems. CMC improves the handling characteristics of ceramic bodies, stabilizes glaze suspensions to prevent settling and separation, supports extrusion and pressing processes, and improves green strength — the mechanical integrity of the shaped ceramic body before it enters the kiln. In selected ceramic systems, HPMC may also be used where additional thickening, binding, or process control support is required.

Cellulose ether grade refers to a product direction designed for a specific industry, application type, purity level, viscosity range, documentation requirement, or performance target. The same product family (such as HPMC or CMC) can have multiple grades — each optimized for different end uses. For example, construction grade HPMC is designed for water retention and workability in cement systems, while pharmaceutical grade HPMC is designed for tablet coating and controlled-release applications with appropriate documentation and purity standards.
Construction grade HPMC and HEMC / MHEC are the most commonly used cellulose ether products in drymix building materials. They are used in tile adhesive, wall putty, cement plaster, gypsum plaster, mortar, EIFS / ETICS systems, repair mortar, self-leveling compounds, and other drymix construction products. Their primary functions are water retention, workability improvement, open time extension, and anti-sag support.
Paint grade HEC is the most widely used cellulose ether in water-based paints and architectural coatings. It provides thickening, rheology control, pigment suspension, flow and leveling support, and storage stability. In selected coating systems, HPMC or CMC may also be considered depending on formulation design and performance requirements.
Detergent grade HEC, HPMC, and CMC may all be used depending on the specific formulation. HEC and HPMC are used to improve viscosity and texture in liquid detergents and cleaners. CMC is especially important in laundry detergent systems because of its anti-redeposition function — it helps prevent loosened soil from redepositing onto fabrics during washing.
Suitable food-grade CMC (also labeled as cellulose gum in food products) and suitable food-grade HPMC may be used in food systems for thickening, stabilization, texture control, water binding, and film forming. Food applications require compliant grades with appropriate documentation, and product selection must be reviewed according to the regulations of the target market. Not every cellulose ether grade is suitable for food use.
Suitable pharmaceutical-grade HPMC and CMC are used in pharmaceutical formulations for tablet binding, tablet film coating, controlled-release matrix systems, capsule-related applications, pharmaceutical suspensions, and topical formulations. Pharmaceutical applications require proper grade selection, technical documentation, regulatory review, and customer-side formulation validation. Not every industrial cellulose ether grade is suitable for pharmaceutical use.
Ceramic grade CMC is the most commonly used cellulose ether in ceramic production. It is used as a binder, suspension stabilizer, and process aid in ceramic tile body, ceramic glaze, extrusion systems, powder pressing, and slip casting. Its key functions include binding, green strength improvement, suspension stability, and glaze stability.
Oilfield grade CMC and selected HEC products are used in water-based drilling fluids, completion fluids, fluid-loss control systems, and specialty oilfield fluid applications. CMC is the primary choice for most oilfield fluid applications due to its viscosity-building and filtration control performance. HEC may be preferred in systems where non-ionic behavior is required.
Yes, but the grade must be specifically suitable for the intended application. The same product family — such as HPMC or CMC — can have different grades for construction, food, pharmaceutical, detergent, or industrial use. Each grade is differentiated by viscosity level, purity, surface treatment, dissolution behavior, and documentation. Using a construction-grade product in a food or pharmaceutical application, for example, would not be appropriate.
Start by identifying your application, required function (water retention, thickening, binding, film forming, etc.), target viscosity, processing method, system type (drymix, liquid, paste, slurry), documentation requirements, and final performance goals. LANDERCOLL can help recommend a suitable grade based on your detailed requirements.
