Hydroxyethyl Cellulose (HEC) Safety Data Sheet (SDS)

Introduction

Hydroxyethyl cellulose (HEC) is a non-ionic, water-soluble cellulose ether derived from natural cellulose. It is widely used in various industries, including pharmaceuticals, cosmetics, and construction, due to its thickening, gelling, and film-forming properties. This article aims to provide an overview of HEC, with a particular focus on its safety data.

Chemical Identification

Hydroxyethyl cellulose is synthesized by the etherification of cellulose, where ethylene oxide reacts with cellulose to create hydroxyethyl groups. It appears as a white to off-white powder and is odorless. The solubility of HEC in water increases with temperature, making it useful in applications where a quick dissolution is required.

Hazards Identification

HEC is generally regarded as safe when used appropriately. However, certain hazards are associated with its handling and storage

- Health Hazards HEC can cause irritation to the eyes, skin, and respiratory tract upon contact. Inhalation of dust may result in respiratory discomfort. Prolonged exposure could lead to more serious health effects. - Environmental Hazards HEC is biodegradable; however, excessive release into water bodies can lead to adverse ecological impacts.

Composition/Information on Ingredients

HEC is composed mainly of hydroxyethyl cellulose. It may contain trace impurities depending on the manufacturing process, but these are typically at levels that do not pose significant risks.

First-Aid Measures

In case of exposure, the following first-aid measures are recommended

- Inhalation Move the affected person to fresh air. If breathing problems persist, seek medical attention. - Skin Contact Wash the affected area thoroughly with soap and water. If irritation persists, consult a medical professional. - Eye Contact Rinse eyes with plenty of water for at least 15 minutes. If irritation continues, seek medical help. - Ingestion Rinse mouth and do not induce vomiting. Seek medical attention if symptoms develop.

Fire-Fighting Measures

HEC is combustible under certain conditions. Firefighting measures include

- Use water spray, foam, or dry chemical extinguishers to combat fires. - Wear self-contained breathing apparatus and protective clothing to prevent inhalation of fumes.

Handling and Storage

For safe handling and storage of HEC

- Store in a cool, dry place away from direct sunlight and heat sources. - Avoid generating dust and provide adequate ventilation when handling the powder. - Ensure containers are tightly sealed to prevent moisture absorption.

Exposure Controls/Personal Protection

To minimize exposure risks, it is advisable to use personal protective equipment

- Wear goggles to protect eyes from dust. - Use gloves to prevent skin contact. - Employ respiratory protection if dust concentration is high.

Conclusion

Hydroxyethyl cellulose is a versatile material with numerous applications across various industries. While it is generally safe, appropriate handling and storage practices are essential to mitigate potential hazards. Users are encouraged to consult the SDS for specific safety guidelines and to ensure compliance with local regulations when dealing with this substance.
