Hydroxyethyl Cellulose (HEC) Safety Data Sheet (SDS)

Introduction Hydroxyethyl cellulose (HEC) is a non-ionic, water-soluble polymer derived from cellulose, widely used in various industrial applications. It is particularly valued for its thickening, binding, and film-forming properties. Commonly found in cosmetics, pharmaceuticals, food products, and construction materials, HEC plays an essential role in enhancing product performance and stability. This article aims to summarize the critical information found in the Safety Data Sheet (SDS) for hydroxyethyl cellulose, outlining its properties, hazards, and safety measures.

Chemical Identification Hydroxyethyl cellulose is identified by several synonyms including, but not limited to, cellulose hydroxyethyl ether and ethyl hydroxyethyl cellulose. Its chemical formula can vary based on the degree of substitution, which affects its solubility and viscosity. HEC typically appears as a white to off-white powder and is odorless.

Physical and Chemical Properties - Appearance White to off-white powder - Solubility Soluble in cold and hot water but insoluble in organic solvents - pH Depending on concentration, typically lies within the range of 6.0 to 8.0 - Molecular Weight Varies significantly based on specific formulation, typically ranging from 70,000 to 150,000 g/mol

Hazards Identification HEC is generally considered safe for use; however, certain precautions should be adhered to. When handling HEC, potential hazards include - Eye Contact May cause irritation; contact with eyes should be avoided. - Skin Contact Generally low risk, but prolonged exposure might lead to slight irritation. - Inhalation Inhalation of dust may irritate the respiratory tract, so adequate ventilation or dust control is recommended.

While HEC is not classified as hazardous under most regulations, users should layer individual evaluations according to local and state laws regarding specific applications.

First Aid Measures In the event of exposure, the following first aid measures should be taken - Inhalation If inhaled, move the person to fresh air. If symptoms persist, seek medical attention. - Skin Contact Remove contaminated clothing and rinse skin with plenty of water. If irritation develops, seek medical help. - Eye Contact In case of contact with eyes, rinse immediately with plenty of water for at least 15 minutes and seek medical attention. - Ingestion Rinse mouth with water. If large quantities are ingested, seek medical advice.

Firefighting Measures HEC is not considered flammable; however, like many organic materials, it can burn under specific conditions. In the case of a fire - Use water spray, foam, or dry chemical extinguishers. - Avoid inhalation of smoke or fumes.

Handling and Storage When handling HEC - Employ local exhaust ventilation to minimize dust exposure. - Use appropriate personal protective equipment (PPE), including gloves and safety goggles. - Store in a cool, dry place away from incompatible materials and sources of ignition. The storage area should be well-ventilated.

Exposure Controls and Personal Protection While HEC does not pose significant exposure risks, using appropriate engineering controls including local exhaust ventilation is advisable. Personal protective measures may include - Gloves to prevent skin contact - Protective eyewear to avoid eye irritation - Respiratory protection if dust formation is likely

Conclusion Hydroxyethyl cellulose is a versatile and widely used material across various industries, valued for its unique properties. Although it is generally safe, it is crucial to follow the guidelines outlined in the Safety Data Sheet to minimize any potential risks associated with exposure. By adhering to proper handling, storage, and personal protective measures, users can safely utilize HEC in their applications, ensuring both efficacy and safety in their products. For any specific concerns or questions regarding HEC's use and safety, consulting with material safety professionals or referring to detailed SDS documentation is recommended.
