Low-viscosity hydroxypropyl methylcellulose is mainly used for self-leveling mortar. Its viscosity is low, although its water retention is poor. HPMC 's leveling property is good, and the mortar is dense. Medium and low-viscosity HPMC is mainly used in tile adhesives, joint fillers, anti-cracking mortars, and thermal insulation mortars. It has good constructability, a good water retention effect, and high mortar density. HPMC exists as a water-retaining agent in mortar. Its water-retaining properties prevent the paste from drying too quickly. And cracking after reapplying.

Beyond these conventional uses, HEC powder is also finding its way into the oil and gas industry, where it is used in drilling fluids to improve wellbore stability and control fluid loss. It is also utilized in the coating industry for its ability to provide excellent film formation and gloss retention.

In the construction industry, HEC finds extensive use as a binding and thickening agent in cement and plaster mixes. Its ability to improve the workability of these materials without compromising their strength is a significant advantage. It also aids in water retention, reducing the need for repeated watering during the curing process.

Medium viscosity (75,000-100,000) is primarily used for putty, as it provides good water retention.

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.

Everything you need to know about HPMC

Understanding the gelation temperature of HPMC is crucial for the development of pharmaceutical formulations with controlled release properties. By optimizing the gelation temperature, researchers can design drug delivery systems that release drugs at specific sites within the body, improving efficacy and reducing side effects.

HPMC is also used in the textile industry as a sizing agent to improve the strength and smoothness of yarns. It is applied to fabrics to reduce friction, prevent fiber damage, and enhance the dyeing process. Additionally, HPMC is used in the production of wallpaper pastes, detergents, and adhesives due to its adhesive and film-forming properties.

Another important application of HPMC is as a stabilizer in emulsions and suspensions. HPMC can prevent particles from settling out of a solution, ensuring uniformity and stability over time. This is crucial in industries such as the food and beverage industry, where emulsions and suspensions are commonly used in products such as salad dressings, sauces, and beverages.

The benefits of incorporating HPMC into pharmaceutical formulations are manifold. By utilizing HPMC as a matrix former in sustained-release dosage forms, pharmaceutical manufacturers can achieve precise control over drug release, leading to optimized therapeutic outcomes and minimized side effects. Furthermore, HPMC’s bioadhesive properties make it suitable for use in ophthalmic formulations, enhancing the contact time of drugs with ocular tissues and improving the efficacy of treatments for conditions such as glaucoma and dry eye syndrome. Additionally, HPMC’s compatibility with a variety of active pharmaceutical ingredients and its ability to enhance solubility and bioavailability further contribute to its value in pharmaceutical applications, making it a preferred choice for formulators seeking to develop safe, effective, and patient-friendly drug products.

In conclusion, Hydroxypropyl Methyl Cellulose (HPMC) is a versatile polymer with a wide range of applications in various industries. Its unique properties make it an essential ingredient in many products, and its versatility ensures its continued use in new and innovative applications. As demand for sustainable and environmentally friendly materials grows, HPMC's biodegradable and non-toxic nature make it an attractive alternative to other synthetic polymers.

Ashland, a global specialty chemicals company, offers a broad range of HEC products under the brand name Aqualon. Their focus lies in providing tailor-made solutions to meet specific customer needs across industries. Similarly, DuPont, known for its advanced materials science, provides high-quality HEC for use in drilling fluids, coatings, and personal care products.

In the personal care industry, HEC is widely used as a thickener and emulsifier. It is commonly found in hair care products such as shampoos, conditioners, and styling gels due to its ability to create a thick, creamy texture without leaving a sticky residue. HEC also helps to stabilize emulsions in skin care products, preventing the separation of oil and water-based ingredients.

Furthermore, HEC is known for its ability to enhance the flow properties of liquids. This is particularly useful in industries such as pharmaceuticals, where precise dosing and dispensing of medications are critical

4. Personal Care Products HPMC is used in the production of hair care products, skin creams, and toothpastes, acting as a thickening agent and providing a smooth feel.

In conclusion, the integration of HPMC into mortar formulations is a testament to the innovative solutions that modern materials science offers the construction industry. With its ability to enhance workability, adhesion, and resistance to cracking, HPMC not only improves the quality of construction but also paves the way for more eco-friendly building techniques. As research continues to explore the full potential of this versatile compound, its role in revolutionizing the world of mortar and construction materials is undeniable.

HPMC is considered safe for human consumption. As HPMC is excreted undigested by the body like a water-soluble dietary fiber, it can be consumed without concern or restriction. Normally there is a so-called ADI value (acceptable daily intake) for the tolerability of food additives. This value indicates the daily dose that is considered medically safe for a lifelong daily intake. The ADI value is set by the German Federal Institute for Risk Assessment and the European Food Safety Authority (EFSA). There is no restriction on the maximum quantity for HPMC, i.e. no ADI value.

A laxative effect may only occur if very high quantities are ingested.

Derived from vinyl acetate-ethylene (VAE) copolymers, redispersible latex powder offers a perfect blend of flexibility, adhesion, and durability. It is manufactured through a process called spray-drying, where liquid latex is transformed into a free-flowing powder, making it easier to handle, transport, and store. The powder can be easily mixed with other dry ingredients, forming a stable, homogenous mixture that, upon hydration, forms a robust, flexible film.

In the food industry, hydroxypropyl methylcellulose is commonly used as a thickener and stabilizer in many processed foods. It is often added to baked goods, dairy products, and sauces to improve their texture and stability. HPMC is also commonly used in dietary supplements as a coating for tablets and capsules, helping to improve the shelf life and stability of the product.
