In tile adhesives and self-leveling compounds, HPMC enhances adhesion, ensuring a strong bond between the substrate and the applied material.
- In summary, HPMC, made primarily from cellulose and chemically modified with hydroxypropyl and methyl groups, is a versatile material with a broad spectrum of applications. Its production process, rooted in chemistry, showcases the transformative power of modifying natural substances to meet specific industrial needs.
- The gelation temperature of HPMC is influenced by several factors, including the molecular weight of the polymer, degree of substitution, concentration, and the presence of salts or other additives. Generally, higher molecular weight HPMC tends to have a lower gelation temperature, as the increased chain length promotes stronger intermolecular interactions.

- Furthermore, HPMC plays a significant role in the food industry. As an emulsifier and stabilizer, it is used in ice cream to prevent ice crystal formation, in salad dressings to maintain consistency, and in bakery products as a dough conditioner.
- 4. Rheology Modifiers HPMC can modify the rheological properties of coatings, allowing them to flow smoothly during application and maintain their shape after drying.
- In addition to plasticizers, accelerators, and retarders, there are various other additives that are used to enhance the performance of cement-based materials. These include air-entraining agents, which are used to improve the freeze-thaw resistance of concrete, and corrosion inhibitors, which help in protecting the reinforcement bars from corrosion. Waterproofing admixtures are also commonly used to make concrete resistant to water penetration, making it suitable for applications in wet environments.

What is Hydroxypropyl Methylcellulose (HPMC)?
Wie gefährlich ist HPMC?
The following conclusions apply only to HPMC meeting the food additive specifications.
The rheological properties of HPMC gel make it suitable for use in self-leveling compounds, ensuring uniform and smooth surfaces in flooring applications.
The safety profile of Hydroxypropyl Methylcellulose (HPMC) has been thoroughly reviewed and approved by several regulatory authorities worldwide, including the European Food Safety Authority (EFSA) and the US Food and Drug Administration (FDA). These approvals underline the safe use of HPMC in both food products and medicines and number E464 is permitted as an additive of food and medicines.
Regulatory Approvals
HPMC is recognized as a safe food additive and pharmaceutical excipient. In the European Union, HPMC is included in the list of permitted substances that can be added to foods and medicines. The EFSA has evaluated HPMC and concluded that it does not pose a significant risk to public health when used according to approved guidelines and therefore number E464 is authorized for use in food.
Support from scientific studies
A series of scientific studies have extensively investigated the safety of HPMC. These studies have shown that HPMC is safe for consumption and has no toxic effects when ingested within stated limits. The studies focus on several aspects, including the degradation of HPMC in the human body and the absence of allergic reactions, which contributes to its profile as a non-irritating and non-sensitizing substance.
