4. Facilité d'utilisation et de dosage


In oil processing, a combination of antifoam and defoamer is often used to maintain optimal fluid dynamics. The choice between these depends on the stage of the process and the type of foam being dealt with. Natural defoaming agents can be particularly useful in refining, where foam can obstruct the separation of oil and water.

4. Moisture Retention The ability of HPMC to retain moisture is pivotal for alleviating symptoms of dryness and promoting healing.


HPMC is a semi-synthetic polymer derived from cellulose, which is a natural polymer obtained from plant cell walls. The basic structure of cellulose consists of linear chains of glucose units linked by β-1,4-glycosidic bonds. To create HPMC, cellulose is modified through chemical reactions involving methylation and hydroxypropylation. The degree of substitution—indicating how many hydroxyl groups on the cellulose backbone are replaced by methyl or hydroxypropyl groups—affects HPMC’s solubility and viscosity.


1. Quality Assurance The supplier’s ability to provide high-quality MCC is crucial. Look for suppliers who adhere to international quality standards, such as Good Manufacturing Practices (GMP) and ISO certifications. This ensures that the MCC you are sourcing is pure, safe, and suitable for its intended application.
