Place the oiled skillet upside down in the preheated oven. To catch any drips, place a baking sheet or aluminum foil on the rack below it. Bake the skillet for about one hour. This process allows the oil to polymerize, forming a hard, non-stick surface.
2. The viscosity of Hydroxypropyl Methylcellulose is related to the size of the molecular weight, and the larger the molecular weight is , the higher the viscosity is. The temperature will also affect its viscosity. As the temperature increases, the viscosity decreases. However, the viscosity of Hydroxypropyl Methylcellulose is less affected by the temperature than Methyl Cellulose, and its solution is stable in storage at room temperature.
The approach followed by the FEEDAP Panel to assess the safety and the efficacy of HPMC is in line with the principles laid down in Regulation (EC) No 429/20087 and the relevant guidance documents: Guidance on technological additives (EFSA FEEDAP Panel, 2012a), Guidance on studies concerning the safety of use of the additive for users/workers (EFSA FEEDAP Panel, 2012b), Guidance on the identity, characterisation and conditions of use of feed additives (EFSA FEEDAP Panel, 2017a), Guidance on the assessment of the safety of feed additives for the target species (EFSA FEEDAP Panel, 2017b), Guidance on the assessment of the safety of feed additives for the consumer (EFSA FEEDAP Panel, 2017c), Guidance on the assessment of the efficacy of feed additives (EFSA FEEDAP Panel, 2018) and Guidance on the assessment of the safety of feed additives for the environment (EFSA FEEDAP Panel, 2019).





buy hydroxypropyl methylcellulose. HPMC is also used in ophthalmic formulations, where it helps improve the viscosity and retention time of eye drops.

hpmc uses. Its water-holding properties also make it a valuable ingredient in gluten-free baking, where it can help improve the texture and shelf-life of gluten-free products.
