Hydroxypropyl Cellulose

Hydroxypropyl Cellulose (HPC) is a water-soluble polymer that is derived from cellulose. It is commonly used in pharmaceuticals, cosmetics, and personal care products. HPC is a versatile and effective thickening agent and film-former, which helps in improving the texture, stability, and viscosity of the products. HPC is used in many pharmaceutical formulations, including tablets, capsules, and suspensions. It is used as a binder, disintegrant, and controlled release agent. In cosmetics and personal care products, HPC is used as a thickener, emulsifier, and stabilizer. It is also used in toothpaste and mouthwash as a viscosity modifier and binder. Chemically, HPC is a hydrophilic polymer that consists of a cellulose backbone with hydroxypropyl groups attached to it. The degree of substitution (DS) of HPC determines the number of hydroxypropyl groups attached to the cellulose backbone. Higher DS values result in increased water solubility and improved film-forming properties. HPC is considered safe for use in pharmaceuticals and personal care products. It is non-toxic, biodegradable, and has a low environmental impact. However, it is important to note that HPC may cause irritation or sensitization in some individuals. Therefore, it is recommended to follow the recommended usage levels and to conduct patch tests before using products containing HPC. Overall, HPC is a versatile and effective ingredient that plays a significant role in many industries.
