For hydroxypropyl cellulose (E 463), the identified NOAEL corresponded to the highest dose 6,000 mg hydroxypropyl cellulose/kg bw per day (by gavage). The most relevant feeding studies with HPMC (E 464) were performed in rats which tolerated up to 10%, corresponding to 9,000 mg test item/kg bw per day. Rabbits tolerated up to 7,500 mg HPMC/kg bw per day administered via the diet (30 day exposure) and dogs up to 1,500 mg HPMC/kg bw per day, in either case being the highest tested dosages. More studies were conducted using sodium carboxy methylcellulose (E 466). The most relevant ones were conducted in rats, with NOAEL values ranging from 4,500 to 9,000 mg test item/kg bw per day (in all cases the highest dose tested). In these studies, some effects (caecum and colonic enlargement, urothelial hyperplasia, nephrocalcinosis, diffuse epithelial hyperplasia in the urinary bladder) were observed, however, not considered of toxicological concern: the findings in the gastrointestinal tract were considered to be a consequence of the accumulation of poorly absorbed water-soluble material and the findings in kidneys and urinary bladder were attributed to the up to fourfold higher concentration of sodium in the test diet compared with the basal diet. In one further study, rats were daily exposed (gavage) to doses equivalent to 0, 500, 2,500 or 5,000 mg/kg bw per day. Animals treated with ≥ 2,500 mg/kg bw per day had soft and pale faeces, which was attributed to the presence of test material and not considered of toxicological relevance. In the absence of any other adverse effects, also for this study, the identified NOAEL was the top dose (5,000 mg/kg bw per day).

Answer: hot water solution method: because HPMC is not dissolved in hot water, so the initial HPMC can be evenly dispersed in hot water, then quickly dissolved when cooling, two typical methods are described as follows:
1) Put the required amount of hot water in the container and heat it to about 70℃. Under the slow stirring gradually add hydroxypropyl methyl cellulose, HPMC began to float on the surface of the water, and then gradually form a slurry, the slurry cooling under the stirring.
2) Add 1/3 or 2/3 of the required amount of water into the container, and heat to 70℃, according to the method of 1), disperse HPMC, prepare hot water slurry; Then add the remaining amount of cold water to the hot slurry, stirring and cooling the mixture.
Powder mixing method: HPMC powder and a large number of other powdery material ingredients, mixing fully with a blender, then add water to dissolve, HPMC at this time can dissolve, and do not stick together, because each small corner, only a little bit of HPMC powder, water will dissolve immediately. - Putty powder and mortar production enterprises are using this method.

- Hydroxypropyl methylcellulose (HPMC) is a cellulose derivative that is made from natural cellulose. During production, the structure is modified in such a way that the properties of the cellulose change, including its solubility. Cellulose is naturally insoluble in water. This is in contrast to HPMC. HPMC is able to bind liquids and form gels at higher temperatures. This property makes it particularly interesting for the food industry. Due to its versatile properties, it can be used in foods as an emulsifier, stabilizer, filler and gelling and thickening agent.
Note: Cellulose is actually an indigestible plant fiber and the main component of plant cell walls, which consists of chains of several hundred to ten thousand glucose molecules. However, the glucose it contains cannot be utilized by humans and is therefore indigestible.
