応用例（製薬）
Hydroxyethylmethyl cellulose is used as an excipient in a wide
range of pharmaceutical products, including oral tablets and
suspensions, and topical gel preparations. It has similar properties
to methylcellulose, but the hydroxyethyl groups make it more
readily soluble in water and solutions are more tolerant of salts and
have a higher coagulation temperature.
安全性
Hydroxyethylmethyl cellulose is used as an excipient in various oral
and topical pharmaceutical preparations, and is generally regarded
as an essentially nontoxic and nonirritant material.
貯蔵
Hydroxyethylmethyl cellulose is hygroscopic and should therefore
be stored under dry conditions away from heat.
