Hydroxyethyl Cellulose Ether

Product Introduction

Hydroxyethyl Cellulose Ether (HEC) is a non-ionic, water-soluble polymer derived from cellulose. It serves as a crucial thickening agent and stabilizer in a variety of applications, particularly in pharmaceuticals and cosmetics. Its ability to modify the viscosity of formulations makes it invaluable in the production of personal care products, such as lotions, creams, and gels. Additionally, HEC is widely used in construction materials and paints, enhancing their performance and stability. Kivi Chemicals supplies Hydroxyethyl Cellulose Ether across Kenya, Uganda, Tanzania, and the wider East African region, catering to the growing demand for high-quality raw materials in these industries.

Detailed Product Overview

Hydroxyethyl Cellulose Ether (HEC), with the chemical formula C2H6O2 and CAS number 9004-62-0, is a modified cellulose derivative prized for its ability to dissolve in water and form clear, viscous solutions. This solubility is achieved through the etherification process, where ethylene oxide reacts with cellulose to form hydroxyethyl groups. The resulting product is a white to off-white powder with a bulk density of 300-500 g/L and a moisture content of ≤ 5%. Its pH range of 6.0 to 8.5 in a 1% solution and viscosity of 1000-3000 mPa.s in a 2% solution make it a versatile thickening agent suitable for a wide range of industrial applications. In industrial applications, Hydroxyethyl Cellulose Ether is extensively utilized across several sectors. In pharmaceuticals, it functions as a binder and film-forming agent, crucial for tablet formulations and other dosage forms, enhancing stability and consistency. The personal care industry benefits from HEC's ability to impart a smooth texture and improve product stability in creams and lotions. In construction, it is used to enhance the workability of mortars and plasters, ensuring better adhesion and cohesion. Additionally, in paints and coatings, HEC helps control viscosity, improves flow properties, and prevents pigment settling, making it a valuable additive in high-performance formulations. When procuring Hydroxyethyl Cellulose Ether, attention should be paid to its industrial grade, which is suitable for general applications in pharmaceuticals and cosmetics. Buyers should verify the product's specifications, such as its density range of 0.5 - 0.7 g/cm³, solubility in water, and low ash content of ≤ 1%, to ensure it meets the stringent requirements for their specific application. The viscosity and pH should also align with the intended use to optimize performance. Checking these parameters upon arrival is crucial to ensure the quality and efficacy of the product in its intended industrial processes. Handling and storage of Hydroxyethyl Cellulose Ether require careful consideration due to its powder form and sensitivity to moisture. It should be stored in a cool, dry place to maintain its efficacy and prevent caking. The product is supplied in 25 kg polypropylene bags, which offer protection from environmental factors during transit and storage. Proper handling procedures should be followed to avoid dust generation and ensure safety during use. As a reputable supplier in the East African market, Kivi Industrial Chemicals Limited ensures that the packaging and supply chain logistics are optimized for timely and efficient delivery to meet the demands of various industrial sectors.
