The FEEDAP Panel used the data provided by the applicant together with data from other sources, such as previous risk assessments by EFSA or other expert bodies, peer-reviewed scientific papers, to deliver the present output.

HPMC gel is added to hair care products such as hair gels and styling creams to provide viscosity and improve the overall texture of the product.

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 methyl cellulose (HPMC) is used as thickening agent and water retaining agent in putty mortar.]

Dispersive ophthalmic viscosurgical device (OVD) used to create and maintain anterior chamber depth and visibility, as well as to protect intraocular tissues during surgery.

So in a new blog series I am going to be asking ‘What On Earth Is…’ about many of the ingredients I see and don’t understand.
