Usage

Description

Methyl 2-hydroxyethyl cellulose is a water-soluble, non-ionic cellulose ether that is derived from natural cellulose. It possesses unique properties such as high solubility, excellent film-forming ability, and good compatibility with various substances. These characteristics make it a versatile ingredient in various industries.

Uses

Used in Pharmaceutical Industry:
Methyl 2-hydroxyethyl cellulose is used as a water retention aid and thickening agent for improving the viscosity and stability of pharmaceutical formulations. It helps in maintaining the consistency and texture of creams, lotions, and ointments, ensuring their effectiveness and ease of application.
Used in Food and Beverage Industry:
In the food and beverage industry, Methyl 2-hydroxyethyl cellulose is used as a protective colloid and suspending agent. It helps in stabilizing emulsions, preventing the separation of ingredients, and enhancing the texture and mouthfeel of various food products.
Used in Cosmetics Industry:
Methyl 2-hydroxyethyl cellulose is used as a binder and stabilizer in cosmetics, providing a smooth and consistent texture to products such as creams, lotions, and gels. It also helps in improving the adhesion and spreadability of makeup products, ensuring a long-lasting and even application.
Used in Textile Industry:
In the textile industry, Methyl 2-hydroxyethyl cellulose is used as a thickening agent and stabilizer for various dyeing and printing processes. It helps in maintaining the uniformity of color and improving the durability of the finished fabric.
Used in Paper and Pulp Industry:
Methyl 2-hydroxyethyl cellulose is used as a binder and stabilizer in the paper and pulp industry, enhancing the strength and quality of paper products. It also helps in improving the water resistance and printability of paper, making it suitable for various applications.

Pharmaceutical Applications

Hydroxyethylmethyl cellulose is used as an excipient in a wide range of pharmaceutical products, including oral tablets and suspensions, and topical gel preparations. It has similar properties to methylcellulose, but the hydroxyethyl groups make it more readily soluble in water and solutions are more tolerant of salts and have a higher coagulation temperature.

Safety

Hydroxyethylmethyl cellulose is used as an excipient in various oral and topical pharmaceutical preparations, and is generally regarded as an essentially nontoxic and nonirritant material.

storage

Hydroxyethylmethyl cellulose is hygroscopic and should therefore be stored under dry conditions away from heat.

Regulatory Status

GRAS listed. Included in nonparenteral medicines licensed in Europe (oral suspensions, tablets, and topical preparations).
