Diethanol Isopropanolamine (DEIPA) 85% is an advanced alkanolamine widely used in the cement and building materials industry as a high-performance cement grinding aid, strength enhancer, and chemical additive. With a typical active content of 85%, DEIPA chemical is valued for its strong chelating ability, high reactivity with cement minerals, and excellent compatibility with supplementary materials such as slag, fly ash, and limestone powder.
Owing to its balanced performance profile, which includes significant early-strength enhancement, reliable long-term strength improvement, low odor, and high chemical stability, DEIPA 85% has become a preferred raw material for modern composite grinding aids, gradually replacing traditional TEA and partially substituting TIPA in high-performance cement formulations.

Applications of Diethanol Isopropanolamine (DEIPA) 85%
1. Raw Material for Cement Grinding Aids
DEIPA diethanol isopropanolamine 85% can be widely used as a key active component in the formulation of high-performance cement grinding aids. It improves grinding efficiency by reducing particle agglomeration, enhances both early and late compressive strength, and optimizes the overall construction performance of cement-based materials. Owing to its balanced performance, DEIPA 85% can partially or even fully replace traditional grinding aids such as triethanolamine (TEA) and triisopropanolamine (TIPA), offering superior cost-effectiveness, better compatibility with mixed materials, and more stable strength development across various cement types.
2. Alkali Reserve in Metalworking Fluids
In the metalworking industry, DEIPA chemical serves as an effective alkali reserve. Its buffering capability helps maintain stable pH levels in metalworking fluids, improving lubrication, reducing corrosion, and enhancing the long-term performance and stability of the cutting or cooling fluid systems.
3. Intermediate for Pesticide and Pharmaceutical Synthesis
85% diethanolisopropanolamine liquid is also used as an important intermediate in the synthesis of various pesticides and pharmaceutical compounds. Its multifunctional chemical structure enables it to participate in multiple organic reactions, making it suitable for producing a wide range of agrochemical formulations and pharmaceutical intermediates that require high reactivity, purity, and stability.
- Significant Early-Strength Improvement. DEIPA chemical effectively accelerates the hydration of key cement minerals, resulting in a noticeable increase in early compressive strength. Its strong promoting effect on C3A and C3S hydration helps cement achieve higher 1-day and 3-day strength, making it highly valuable for applications requiring fast setting and early load-bearing capacity.
- Better Later-Strength Development. In addition to its early-strength benefits, DEIPA 85% also supports robust long-term strength development. Compared with TEA, it provides a more pronounced improvement in 28-day compressive strength, ensuring that cement maintains consistent and stable mechanical performance throughout the full curing period.
- Eco-Friendly and Low-Volatility. This product is considered a more environmentally friendly grinding aid due to its low odor, low volatility, and good biodegradability. Its high chemical stability contributes to safe handling and storage, while its excellent compatibility allows it to blend well with most other cement additives without causing adverse interactions.
- Cost-Reduction for Cement Plants. By improving grinding efficiency and reducing coating in the mill, diethanol Isopropanolamine (DEIPA) helps lower overall energy consumption during cement production. It also offers the possibility of reducing the clinker factor while still maintaining strength performance, especially in systems with high levels of supplementary cementitious materials such as slag, fly ash, and limestone. This leads to more stable cement quality and improved production economics.
The recommended dosage of diethanol Isopropanolamine (DEIPA) 85% typically falls within 0.02% to 0.08% of the total cement weight. The optimal dosage should be determined according to specific production conditions, including clinker mineral composition, cement fineness, gypsum content, and the desired early or late strength performance. Adjustments may be required based on the characteristics of supplementary cementitious materials, production temperature, and grinding system efficiency to achieve the best balance of strength enhancement and grinding performance.
Methods of Application
DEIPA 85% is generally introduced directly into the cement grinding process through a dosing pump to ensure accurate and continuous feeding. It can be used as a standalone grinding aid or combined with TIPA, TEA, glycerol, sugars, and various inorganic modifiers to formulate customized composite grinding aids tailored to different clinker types and performance targets. Due to its excellent solubility and compatibility, diethanolisopropanolamine 85% is suitable for incorporation into both liquid and powder-based additive formulations, providing flexibility for diverse manufacturing systems and application requirements.
(1) Packaging
DEIPA 85% is supplied in a variety of industrial-grade packaging options to meet different production and transportation requirements. The standard packaging includes 230 kg HDPE drums, which provide excellent chemical resistance and are convenient for medium-scale users. For larger-volume applications, the product is also available in 1100 kg IBC totes, offering improved handling efficiency and reduced storage space. Additionally, bulk tank trucks can be arranged for high-consumption customers, allowing for direct unloading into storage tanks and ensuring a continuous, cost-effective supply chain. Custom packaging solutions can be provided upon request to accommodate specific operational needs.
(2) Storage Conditions
To maintain product quality and stability, diethanol Isopropanolamine 85% should be stored in a cool, dry, and well-ventilated area, away from sources of heat and direct sunlight. Exposure to high temperatures may affect viscosity and long-term stability, while moisture ingress should be avoided to prevent dilution or contamination. Containers must be kept tightly sealed when not in use to ensure consistent performance. Under properly sealed and recommended storage conditions, the product has a shelf life of approximately 12 months without deterioration.
