Audited Supplier Hypromellose/Hydroxypropyl Methylcellulose/HPMC
Introduction
English name: HPMC
Other Name: Hypromellose/Hydroxypropyl Methylcellulose/
CAS#: 9004-65-3
EC: 618-389-6
Appearance: White powder
Hydroxypropyl methylcellulose, abbreviated as HPMC, is a variety of nonionic cellulose mixed ethers. It is a semi-synthetic, inactive, viscoelastic polymer that is often used in ophthalmology as a lubricant or as an excipient or excipient in oral medications and is found in a wide variety of commodities.
In addition, as a food additive, hypromellose can play the following roles: emulsifiers, thickeners, suspending agents, and animal gelatin substitutes.
The application scope of HPMC:
Used in shampoos, body washes, facial cleansers, lotions, creams, gels, toners, conditioners, styling products, toothpastes, slobbers, toy bubble water
Packaging specifications:
25 kg / bag
Advantages:
Water soluble and thickening ability: this product is soluble in cold water, and it can form transparent sticky solution. In organic solvent of dissolved: because it contains a certain amount of hydrophobic methoxyl, this product is soluble in some organic solvent; it is also soluble in water and organic mixed solvent.
Hydroxypropyl methyl cellulose (HPMC) salt resistance: because ion and the polyelectrolytein exsist in this product, its metal salt or organic electrolyte aqueous solution is stable.
Surface activity: HPMC for daily chemical aqueous solution has the surface activity, ensuring its emulsification, protective colloid and relative stability.
Low ash content: because ion exist in this product, in preparation process we can use hot water washing for effective refinement, so its ash content is very low.
pH stability: HPMC aqueous solution viscosity in the range of pH3.0-11.0 is more stable.
Water retention effect: this product is hydrophilic and its solution has high viscosity.
Film-forming property: HPMC can generate strong pliable and transparent sheet, which has the good oil resistance to ester performance.
