Hydroxypropyl Methylcellulose(HPMC)

Hydroxypropyl methylcellulose (HPMC) is produced by treating cellulose with sodium hydroxide to form alkali cellulose, which is then reacted with propylene oxide and methyl chloride to substitute hydroxyl groups on the cellulose chain with hydroxypropyl and methyl groups, respectively.

HPMC is a synthetic polymer that is quite popular in cosmetics, personal care and cleaning products. It is a highly versatile ingredient that serves as a thickener, emulsifier, and stabilizer in formulations. HPMC can help in improving the texture and flow properties of products like lotions, creams, gels and liquids. It also controls the release of active ingredients and acts as a film-forming agent, protecting the skin from environmental stressors.
