Is hydroxypropyl cellulose toxic?

Hydroxypropyl cellulose (HPC) is a non-toxic, biodegradable, and water-soluble polymer derived from cellulose. It is used in a wide range of products, including pharmaceuticals, cosmetics, food, and industrial products. HPC is generally considered to be safe for human consumption and is approved for use in food and cosmetic products by the U.S. Food and Drug Administration (FDA).

HPC is a non-toxic, non-irritating, and non-allergenic substance. It is not considered to be a carcinogen, mutagen, or teratogen, and it does not cause any adverse effects in humans or animals when used in accordance with the recommended dosage. HPC is also not known to be a reproductive or developmental toxicant.

In addition, HPC is not known to be an environmental hazard. It is not considered to be persistent, bioaccumulative, or toxic (PBT) or very persistent and very bioaccumulative (vPvB). HPC is also not listed as a hazardous substance or pollutant under the Clean Air Act or the Clean Water Act.

HPC is used as a thickener, emulsifier, and stabilizer in cosmetic formulations such as shampoos, conditioners, and lotions.

Despite its non-toxic nature, HPC should still be handled with care. Ingestion of large amounts of HPC may cause gastrointestinal irritation, nausea, vomiting, and diarrhea. Inhalation of HPC dust may cause irritation of the nose, throat, and lungs. Eye contact with HPC may cause irritation and redness.

In conclusion, hydroxypropyl cellulose is generally considered to be safe for human consumption and is approved for use in food products by the FDA. It is not considered to be a carcinogen, mutagen, or teratogen, and it does not cause any adverse effects in humans or animals when used in accordance with the recommended dosage. HPC is also not known to be an environmental hazard and is not listed as a hazardous substance or pollutant under the Clean Air Act or the Clean Water Act. However, ingestion of large amounts of HPC may cause gastrointestinal irritation, nausea, vomiting, and diarrhea, while inhalation of HPC dust may cause irritation of the nose, throat, and lungs. Eye contact with HPC may cause irritation and redness.
