These evaluations have consistently concluded that HPMC is safe for use in the specified applications, including pharmaceuticals and food products. The FDA has even classified HPMC as Generally Recognized as Safe (GRAS), further affirming its safety profile.

Moreover, it is worth mentioning that HPMC is not listed as a known or suspected carcinogen by reputable organizations such as the International Agency for Research on Cancer (IARC) or the National Toxicology Program (NTP). These organizations extensively review scientific literature and conduct rigorous assessments to determine the carcinogenicity of various substances. The absence of HPMC from their lists further supports its safety.

In conclusion, while concerns have been raised regarding the potential carcinogenicity of hydroxypropyl methylcellulose (HPMC), the available evidence suggests that it is a safe compound when used in the specified applications. Regulatory bodies and reputable organizations have conducted thorough evaluations and have consistently concluded that HPMC does not pose a significant risk of cancer.
