Safety Data Sheet (SDS) for Hydroxypropyl Methylcellulose (HPMC)

Hydroxypropyl methylcellulose (HPMC) is a synthetic polymer widely used in various industries, including pharmaceuticals, food, and construction. As with any chemical substance, understanding its properties, handling procedures, and safety measures is crucial for anyone working with or around HPMC. This article summarizes key information from the Safety Data Sheet (SDS) for hydroxypropyl methylcellulose.

Chemical Identification

HPMC is a non-ionic cellulose ether that is soluble in water, forming a colloidal solution. Its chemical formula can vary, but it is generally characterized by the presence of hydroxypropyl and methoxy groups. Common applications include use as a thickening agent, binder, and film-forming agent, particularly in pharmaceutical formulations and food products.

Hazard Identification

HPMC is generally considered to have low toxicity and is not classified as hazardous according to current regulations. However, it can cause mild irritation to the eyes and skin upon prolonged contact. Inhalation of dust generated from HPMC powders may also lead to respiratory irritation. Thus, appropriate precautions should be taken while handling HPMC to minimize any potential health risks.

Composition

The primary component of HPMC is cellulose, modified to achieve desired water solubility and viscosity properties. HPMC is often available in various grades, which differ in the degree of substitution and molecular weight, directly influencing its functionality in applications.

First-Aid Measures

In case of exposure, it is essential to follow first-aid procedures based on the type of exposure - Inhalation Move the affected individual to fresh air immediately. If symptoms persist, seek medical attention. - Skin Contact Rinse the skin thoroughly with soap and water. If irritation develops, consult a physician. - Eye Contact Flush the eyes with plenty of water for at least 15 minutes. Remove contact lenses if present and seek medical attention if irritation continues. - Ingestion If ingested, do not induce vomiting. Rinse the mouth and seek medical help.

Fire-Fighting Measures

HPMC is not considered flammable; however, in the event of a fire, it can produce hazardous fumes and combustion products. Use appropriate extinguishing media such as water spray, foam, or dry chemical. Firefighters should wear suitable protective equipment and self-contained breathing apparatus.

Handling and Storage

When handling hydroxypropyl methylcellulose, it’s imperative to wear appropriate personal protective equipment (PPE), including gloves, goggles, and dust masks if necessary. Ensure good ventilation in work areas to minimize dust accumulation. Store HPMC in a cool, dry place, away from sources of heat or ignition, and keep containers tightly closed when not in use.

Conclusion

Understanding the properties and safety information related to hydroxypropyl methylcellulose is essential for safe handling and application. By adhering to the guidelines specified in the Safety Data Sheet, workers can mitigate risks and ensure a safe working environment. Regular training and adherence to safety protocols will enhance awareness and promote safety in workplaces using HPMC. For further information, users should always refer to the specific SDS provided by the manufacturer for the particular grade of HPMC they are handling.
