CAS (Chemical Abstracts Service) numbers are unique identifiers assigned to chemical substances, enabling accurate information retrieval in scientific research and databases. The CAS number 9004-62-0 specifically denotes hydroxyethyl cellulose, which is derived from cellulose, a natural polymer abundant in plant cell walls. The '9004' segment of the CAS number signifies that HEC falls under the category of Polymers and Resins, while the following digits '62-0' are unique to this particular compound.

HPMC is also commonly found in food products as a thickening agent, stabilizer, and emulsifier

hydroxypropyl methyl cellulose cas no. Its inert nature makes it safe for consumption and it is commonly used in dairy products, sauces, and desserts to improve texture and consistency. In addition, HPMC is used in gluten-free baking to replicate the structural properties of gluten in doughs and batters.

HPMC is also valued for its biodegradability and non-toxic nature. It is considered safe for use in food and pharmaceutical applications and is approved for use by regulatory bodies such as the US Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA).

The 'HPMC%' you might encounter refers to the percentage concentration of HPMC in a particular product. This percentage can vary depending on the intended application and desired effects. Higher percentages typically result in thicker consistency or slower drug release.

In the paint and coating industry, HPMC is used as a binder, which improves the flow and leveling properties of the paint, reduces brush marks, and enhances the overall finish. It also aids in the water resistance and durability of the coating.

2. **Local Chemical Distributors** For those preferring a more personal touch, local chemical distributors can provide tailored advice and support. Check your regional business directories or search engines for suppliers near you. Companies such as Brenntag, Ashland, and Kemira are known for their wide range of specialty chemicals, including HEC.

Introduction

Do not take hydroxypropyl methylcellulose by mouth. If hydroxypropyl methylcellulose is put in the mouth or swallowed, call a doctor or poison control center right away.

The degree of substitution (DS), defined as the average number of hydroxyethyl groups per glucose unit, plays a crucial role in determining the properties of HEC. A higher DS leads to greater hydrophilicity and improved solubility. However, it also affects other attributes such as solution viscosity, thickening efficiency, and thermal stability However, it also affects other attributes such as solution viscosity, thickening efficiency, and thermal stability

hydroxyethyl cellulose chemical formula. Manufacturers can tailor the DS to suit specific applications, creating HEC variants with precise performance characteristics.

In an era where sustainable solutions are not just a preference but a necessity, hydroxyethylcellulose (HEC), a natural derivative from cellulose, emerges as a versatile and eco-friendly ingredient that holds significant promise. Derived from the abundant natural resource of wood pulp or cotton fibers, HEC is a testament to how nature's bounty can be transformed into a powerful tool for various industries.

MHEC is synthesized through a chemical modification process where cellulose is treated with alkali, followed by etherification with ethylene oxide and methylation. The outcome is a product with a unique combination of features it is non-toxic, biodegradable, and has excellent film-forming, thickening, and stabilizing capabilities.

Tiles are an essential component of modern construction, used for flooring, wall cladding, and other applications. However, ensuring optimal adhesion between tiles and the underlying surface is crucial for the long-term durability and aesthetics of the installation. Conventional adhesives often fall short in terms of bond strength, water resistance, or both, leading to premature failure or unsightly gaps.

The degree of substitution, referring to the number of hydroxyl groups replaced by methyl and hydroxypropyl groups, plays a significant role. Higher degrees of substitution generally lead to better water solubility as these modifications enhance the hydrophobicity of the polymer, allowing it to disperse more easily in water.

3. Non-toxicity HPMC is non-toxic and biodegradable, making it an environmentally friendly option for various applications.

What else can hydroxypropyl methylcellulose be called?

In conclusion, HPMC is indeed safe for use in its intended applications, backed by scientific research and regulatory approvals. Its safety profile, coupled with its functional benefits, makes it a popular choice across multiple industries. Nonetheless, users should always adhere to safety guidelines and recommended usage to minimize potential risks.

The concentration of HEC in the solution also impacts its thickening properties. Below a certain concentration, the individual HEC chains do not interact effectively, resulting in low viscosity. However, beyond this threshold, a network of interconnected chains forms, significantly increasing the solution's viscosity. This concentration-dependent viscosity is a characteristic feature of associative thickeners like HEC.

The global redispersible polymer powder market is highly competitive, with key players continually investing in research and development to introduce innovative products. Companies like Wacker Chemie AG, BASF SE, and Dow Chemical Company, among others, are instrumental in shaping the market dynamics through their extensive product portfolios and global reach.

In the food industry, HPMC is used as a thickener, stabilizer, and emulsifier in various food products such as sauces, dressings, and dairy products. Its ability to improve the texture and mouthfeel of food products without altering their taste or aroma makes it a valuable ingredient in the food industry. In the construction industry, HPMC is used as a thickening agent in cement-based products such as tile adhesives, grouts, and plaster compounds. Its high water retention capacity and excellent workability properties make it an essential additive in construction materials

Textile manufacturers utilize VAE powder to create eco-friendly coatings and finishes, which not only improve the fabric's durability but also offer water-repellent and flame-retardant properties

The science behind liquid thickeners lies in their ability to form colloidal dispersions or gels when mixed with liquids. The molecules in these substances either absorb water, forming a gel matrix, or associate with each other to increase viscosity. The choice of thickener depends on factors such as the desired final texture, the temperature sensitivity of the product, and any dietary restrictions.

In addition to its many uses in the food industry, HPMC is also used in many other areas. For example, in the building materials industry to regulate flow properties, in the production of cosmetics such as toothpaste, shampoo, soap, cream and lotion and in the pharmaceutical industry as a component of medicines.

Answer: MC stands for Methyl Cellulose, which is derived from refined cotton treated with alkali. It is then etherified using methyl chloride as the etherifying agent, resulting in cellulose ether through a series of reactions. The degree of substitution is generally between 1.6 and 2.0, and different degrees of substitution result in different solubilities. It belongs to the nonionic type of cellulose ether.
