Hydroxyethylcelluloseis the most commonly used thickener in latex coatings. In addition to thickening latex paint, it also has the functions of emulsifying, dispersing, stabilizing and retaining water. It is characterized by significant thickening effect, good color development, film-forming properties and storage stability. Hydroxyethylcellulose is a non-ionic cellulose derivative that can be used over a wide pH range. It has good compatibility with other materials in the composition such as pigments, additives, fillers and salts. Coatings thickened with hydroxyethyl cellulose have good rheology at various shear rates and are pseudoplastic. Construction methods such as brushing, roller coating, and spraying can be used. It has good construction properties, is not easy to drip, sag and splash, and has good leveling properties.
One notable property of HPMC is its ability to form a gel upon heating, which is a critical feature for various applications. It is also pH-stable, meaning it does not significantly change its properties across a wide range of pH levels. This characteristic makes it ideal for pharmaceutical and food applications where pH can vary. Furthermore, HPMC is known for its excellent film-forming ability, providing a protective barrier against moisture, heat, and chemicals.
In the food sector, HPMC serves as a thickener, emulsifier, and stabilizer. It is commonly found in gluten-free products, soups, sauces, and ice creams. Its ability to retain moisture makes it an excellent ingredient for baked goods, improving texture and extending shelf life. Additionally, HPMC enhances the mouthfeel of low-fat products, allowing manufacturers to reduce fat content without compromising taste.
The food industry also benefits from hydroxyalkyl cellulose, where it functions as a food additive. It acts as a thickener, stabilizer, and emulsifier, improving the texture and mouthfeel of various food products. HAC is commonly used in bakery products, sauces, and dairy products, contributing to enhanced quality and shelf-life. Moreover, as consumer demand for clean-label products rises, the use of hydroxyalkyl cellulose, which is considered a safe and non-toxic ingredient, aligns well with market trends focused on natural and health-conscious choices.
