Hydroxyethyl Cellulose (HEC) is a commonly used thickener, emulsifier and stabilizer, widely used in coatings, cosmetics, detergents, building materials and other fields. Its usage ratio is usually determined according to the specific application scenario and formulation requirements.
1. Coatings Industry
In water-based coatings, hydroxyethyl cellulose is often used as a thickener and suspending agent to help adjust the viscosity and rheology of the coating. Usually, the usage ratio is 0.1% to 2.0% (weight ratio). The specific ratio depends on the type of coating, the required rheological properties and the combination of other ingredients.
2. Cosmetics and personal care products
In cosmetics, hydroxyethyl cellulose is used as a thickener and stabilizer to help improve the texture and application performance of the product. The common usage ratio is 0.1% to 1.0%. For example, in shampoo, facial cleanser, lotion and gel, HEC can provide good touch and stability.
3. Cleaners and detergents
In liquid cleaners, hydroxyethyl cellulose is used to adjust the viscosity and suspension of the product and prevent the precipitation of solid components. The usage ratio is usually 0.2% to 1.0%. The amount of HEC used in different types of cleaning products may vary.
4. Building materials
In building materials, such as cement slurry, gypsum, tile adhesives, etc., hydroxyethyl cellulose is used as a water retainer and thickener. Usually, the usage ratio is 0.1% to 0.5%. HEC can improve the construction performance of the material, extend the operation time, and improve the anti-sagging property.
5. Other applications
Hydroxyethyl cellulose is also widely used in other fields, such as food and medicine. The usage ratio is usually adjusted according to the specific application requirements. For example, in the food industry, HEC can be used as a thickener, stabilizer and emulsifier, and its usage is usually very low.
Precautions
When using hydroxyethyl cellulose, you need to pay attention to the following points:
Dissolution method: The solubility of HEC is affected by temperature, pH value and stirring conditions. It usually needs to be added slowly to water and stirred thoroughly.
Formula compatibility: Different formula ingredients may affect the performance of HEC, so compatibility testing is required during the formulation development process.
Viscosity control: According to the needs of the final product, choose the appropriate HEC type and dosage to achieve the required viscosity.
The usage ratio of hydroxyethyl cellulose is a flexible parameter that needs to be adjusted according to the specific application and formulation. Understanding the performance of HEC in different applications can help optimize product performance and quality.
