Hydroxyethyl cellulose (HEC) is a water-soluble polymer derived from cellulose, a natural polymer found in plants. HEC is commonly used as a thickener, emulsifier, binder, and stabilizer in various industries, including pharmaceuticals and food.
In the pharmaceutical industry, HEC is used as a binder in tablet formulations, as a thickener and stabilizer in liquid and semi-solid dosage forms, and as a coating agent for tablets and capsules. It is also used in ophthalmic preparations, such as eye drops and contact lens solutions, as a viscosity enhancer and lubricant.
In the food industry, HEC is used as a thickener and stabilizer in various food products, including sauces, dressings, and beverages. It is also used as a texture modifier in ice cream and as a coating agent for fruits and vegetables to improve their appearance and shelf life.
HEC is considered safe for consumption by the US Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). However, excessive intake of HEC can cause digestive issues such as bloating, gas, and diarrhea.
In summary, Hydroxyethyl cellulose has various applications in the pharmaceutical and food industries, primarily as a thickener, stabilizer, and binder. It is considered safe for consumption but should be consumed in moderation to avoid digestive issues.
