The end product is vegan … but is it still natural? By contrast, gelatine has been the safe and trusted ingredient of choice for more than 100 years. And, as gelatine is a foodstuff, rather than a food additive, its use is neither limited nor restricted. It doesn’t even have an e-number. Furthermore, gelatin is GMO-free and sustainable, obtained from natural resources such as pig or bovine skin (by-products from the meat industry) using gentle hot water extraction. And, although being sourced from animals, specific varieties of gelatine can be used to meet the strict religious requirements of Hindus and Muslims, for example; even Kosher versions can be supplied.
One of the key advantages of redispersible polymer powders is their ability to improve the performance of construction materials. When added to cement-based systems, these powders can enhance the strength, durability, and workability of the mixture. This is particularly useful in the production of high-performance concrete, which is increasingly in demand for its ability to withstand harsh environmental conditions such as extreme temperatures, heavy loads, and chemical attacks. RDP powder price refers to the cost of Redispersible Polymer Powder which is a free-flowing white powder that can improve the properties of cement-based or gypsum-based dry mix products. This popular construction material additive is widely used in the construction industry due to its excellent performance and versatility. MHEC (Methyl Hydroxyethyl Cellulose) is a cellulose ether that is widely used in a variety of industries such as construction, pharmaceuticals, and cosmetics. It is a white or off-white powder that is soluble in water and forms a clear, viscous solution. MHEC is derived from natural cellulose and is chemically modified to enhance its properties. Redispersible polymer powders, a unique class of construction chemicals, play a pivotal role in various industries, particularly in the building and construction sector. These powders, derived from water-soluble polymers, offer exceptional performance characteristics due to their ability to re-form into a stable dispersion when redispersed in water. This feature makes them indispensable for applications such as tile adhesives, mortar, and plaster formulations. The solubility characteristics of HPMC also play a crucial role in its functionality. It is generally regarded as soluble in hot water and insoluble in organic solvents such as alcohol and acetone. This selective solubility allows for targeted release mechanisms within the gastrointestinal tract, enhancing the bioavailability of active ingredients. In the field of coatings, these polymers offer superior film formation, gloss, and chemical resistanceAppearance: White or similar white powder.
In the cosmetics industry, HPMC is used in a wide range of products such as creams, lotions, and gels. Its properties as a thickener and emulsifier make it an ideal ingredient for cosmetic formulations. The price of HPMC can impact the overall cost of manufacturing cosmetics, so companies need to carefully monitor and manage the price of this compound to ensure profitability. In construction, HPMC finds extensive use in the production of mortar and plaster. It improves the workability of these materials, reducing water demand, and enhancing their setting time and durability. HPMC also acts as a retarder, preventing premature hardening, and improves the adhesion of coatings and paints, making them more resistant to cracking and water damage HPMC also acts as a retarder, preventing premature hardening, and improves the adhesion of coatings and paints, making them more resistant to cracking and water damageThe 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.
