  • The first distinction among HPMC types lies in their substitution pattern. The ratio of hydroxypropyl (HP) to methyl (M) groups varies, affecting solubility and gel strength. Low-viscosity HPMC, with a higher proportion of HP groups, tends to be more soluble and is often used for immediate-release formulations. In contrast, high-viscosity HPMC, rich in M groups, provides a stronger gel network, making it suitable for extended-release applications.
  • One of the primary advantages of using HPMC in wall putty is its ability to maintain workability. The viscous nature of HPMC allows the putty to be easily applied and spread across walls without dripping or sagging. This characteristic is essential for contractors and DIY enthusiasts alike, as it reduces the effort required during application and leads to a more even finish.
  • The safety data sheet (SDS) for hydroxyethyl cellulose provides important information about the potential hazards and safe handling practices associated with the chemical. It outlines the physical and chemical properties of the compound, as well as the potential health effects of exposure. The SDS also includes information on proper storage and disposal procedures, as well as emergency measures in case of accidental release or exposure.
  • Do not use if the solution is cloudy, leaking, or has particles.
  • In addition to its role in controlled release formulations, HPMC is also used as a binder in tablet manufacturing. HPMC helps to improve the mechanical properties of tablets, such as their hardness and friability, while also enhancing their disintegration and dissolution properties. This makes HPMC an essential ingredient in the production of high-quality pharmaceutical tablets.

  • HPMC is a semi-synthetic polymer derived from cellulose by replacing some of the hydroxyl groups with hydroxypropyl and methyl groups. This modification endows HPMC with excellent hydrophilic, film-forming, and thickening properties. However, the solubility of HPMC in water can vary depending on several factors, including the degree of substitution, molecular weight, and temperature.
  • In the pharmaceutical sector, HPMC serves as an excipient in tablets, acting as a binder, disintegrant, or coating agent. It is also used in controlled-release formulations due to its pH-independent swelling properties. Additionally, it finds application in ophthalmic solutions, serving as a viscosity enhancer and stabilizer.
  • In the pharmaceutical sector, HEC serves as a binder, disintegrant, and viscosity enhancer in tablet formulations. It also plays a crucial role in controlled drug release systems due to its ability to form gel matrices. In cosmetics, HEC powder is used as a stabilizer and emulsion stabilizer in lotions, creams, and hair care products, ensuring their smooth texture and consistent performance.

  • The Joint FAO/WHO Expert Committee on Food Additives (JECFA, 1990) assessed the compound together with six other cellulose derivatives and allocated a group acceptable daily intake (ADI) of ‘not specified’. The Scientific Committee for Food (SCF, 1994, 1999) who assessed five closely related cellulose derivatives, also allocated a group ADI of ‘not specified’. The most recent evaluation of cellulose and cellulose derivatives, including HPMC for their use as food additives was done in 2018 by the EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) (EFSA ANS Panel, 2018), which concluded that there was no need to set a numerical ADI.

  • At the heart of HPMC's functionality lies its polymeric structure. HPMC is a cellulose derivative where some of the hydroxyl groups are replaced by methoxyl and hydroxypropyl substituents. This substitution disrupts the extensive hydrogen bonding typical of native cellulose, imparting solubility in cold water. The balance between these substituents and their distribution along the polymer backbone significantly impacts HPMC's solubility, viscosity, and gel-forming properties.


  • Major Producers:

    The largest HPMC manufacturers are global chemical and pharmaceutical companies that have manufacturing capabilities in several countries. Among these, we can mention Dow Chemical Company, Ashland, and Shin-Etsu Chemical. These companies are known for their ability to produce high-quality HPMC suitable for a wide range of applications, including those requiring high standards such as the pharmaceutical and food industries.

    Importance in the Gluten Free Food Industry:

    In the context of gluten-free, the importance of HPMC has grown alongside the growing awareness and diagnosis of celiac disease and other gluten sensitivities. The need for gluten-free products that maintain the sensorial and structural qualities of traditional foods has driven the search for effective additives such as HPMC.

    Current Considerations:

    Although HPMC is widely used and generally considered safe, the current trend in the food industry is moving towards less processed and more natural ingredients. This may influence consumer perceptions of HPMC and other similar additives. However, its effectiveness as a gluten substitute in gluten-free preparations still makes it a valuable ingredient for many producers and consumers.
