  • In paints and coatings, HEC acts as a protective colloid, preventing pigment sedimentation and improving the application properties of the paint. Its viscosity-enhancing attribute ensures an even coat, reducing the occurrence of runs or sags. Furthermore, HEC contributes to the durability of the paint by forming a stable film upon drying, which resists cracking and peeling over time.
  • In conclusion, the integration of HPMC into gypsum plaster formulations addresses many of the material's inherent limitations. By enhancing workability, water retention, adhesion, water resistance, and contributing to more sustainable building practices, HPMC elevates the performance of gypsum plaster. These improvements ensure that gypsum plaster remains a preferred choice for builders, sculptors, and designers who demand both excellence in performance and aesthetics in their work.
  • The degree of substitution (DS), defined as the average number of hydroxyethyl groups per glucose unit, plays a crucial role in determining the properties of HEC. A higher DS leads to greater hydrophilicity and improved solubility. However, it also affects other attributes such as solution viscosity, thickening efficiency, and thermal stability However, it also affects other attributes such as solution viscosity, thickening efficiency, and thermal stability However, it also affects other attributes such as solution viscosity, thickening efficiency, and thermal stability However, it also affects other attributes such as solution viscosity, thickening efficiency, and thermal stabilityhydroxyethyl cellulose chemical formula. Manufacturers can tailor the DS to suit specific applications, creating HEC variants with precise performance characteristics.

  • The applicant did not provide new studies on the safety of HPMC, but made reference to previous assessment of celluloses (as a group) performed by other scientific bodies. Cellulose and cellulose derivatives were evaluated for their safety by JECFA (1990), which allocated a group ADI of ‘not specified’. The last comprehensive evaluation of cellulose and cellulose derivatives, including HPMC, for their use as food additives was done in 2017 by the ANS Panel (EFSA ANS Panel, 2018), which concluded that there was no need to set a numerical ADI. Although the data set available for the different celluloses is not complete and most of the studies were old and do not meet the current requirements of toxicological testing, the ANS Panel considered that the physico-chemical, structural, biological and kinetic similarities between the modified celluloses make it possible to apply a read-across approach among the different celluloses.
