About Hydroxy propyl methyl cellulose

Hydroxy propyl methyl cellulose
CAS number [9004-65-3]

Hypromellose (INN), short for hydroxypropyl methylcellulose (HPMC), is a semisynthetic, inert, viscoelastic polymer used as an ophthalmic lubricant, as well as an excipient and controlled-delivery component in oral medicaments, found in a variety of commercial products.

As a food additive, hypromellose is an emulsifier, thickening and suspending agent, and an alternative to animal gelatin. Its Codex Alimentarius code (E number) is E464.
Hypromellose is a solid, and is a slightly off-white to beige powder in appearance and may be formed into granules. The compound forms colloids when dissolved in water. Although non-toxic, it is combustible and can react vigorously with oxidising agents.

Hypromellose in an aqueous solution, unlike methylcellulose, it does not exhibit thermal gelation property. That is, when the solution heats up to a critical temperature, the solution congeals into a non-flowable but semi-flexible mass. Typically, this critical (congealing) temperature is inversely related to both the solution concentration of HPMC and the concentration of the methoxy group within the HPMC molecule (which in turn depends on both the degree of substitution of the methoxy group and the molar substitution. That is, the higher is the concentration of the methoxy group, the lower is the critical temperature. The inflexibility/viscosity of the resulting mass, however, is directly related to the concentration of the methoxy group (the higher is the concentration, the more viscous or less flexible is the resulting mass).

FAQs of Hydroxy propyl methyl cellulose :

Q: How is Hydroxy propyl methyl cellulose (HPMC) typically used in industrial applications?

A: HPMC is primarily used as a thickening agent, stabilizer, and binder. In construction, it improves water retention and workability. In the paint industry, it provides texture and prevents pigment separation. It is also used in ceramics, detergents, cosmetics, pharmaceuticals, and processed foods for its stabilizing and emulsifying properties.

Q: What distinguishes your HPMC from other similar additives?

A: Our HPMC stands out due to its 99% purity, odorless quality, absence of fat and protein, and consistent powder form. The product is specifically designed for industrial use, offering versatility and performance across multiple sectorsall packed securely in moisture-proof 25 kg bags.

Q: When should HPMC be incorporated into the production process?

A: HPMC should typically be dissolved in cold water before being added to mixtures. This ensures even dispersion and maximizes its thickening and stabilizing attributes. Its best added at stages where consistency and retention properties are critical for the final products performance.

Q: Where is your HPMC most commonly applied?

A: Our HPMC is widely used in construction materials, paints, ceramics, detergents, cosmetics, pharmaceuticals, and the food industry. Its solubility and neutral flavor make it suitable for diverse industrial applications where high quality is essential.

Q: What benefits does HPMC offer in construction and paint formulations?

A: HPMC enhances water retention and workability in construction products such as tile adhesives and plasters. In paints, it improves consistency and prevents the separation of components, leading to a smoother application and better finished results.

Q: How should HPMC be stored to maintain its quality?

A: HPMC should be stored in a cool, dry place in its original sealed 25 kg bag to keep its moisture content below 5%. Proper storage ensures a shelf life of up to 2 years, preserving its functional and chemical properties.
