Hydroxyethylcellulose

Hydroxyethylcellulose (HEC) is a non-ionic, water-soluble polymer derived from cellulose. It is widely used in cosmetic and pharmaceutical formulations due to its thickening, gelling, and stabilizing properties.

Clinical Evidence

Multifunctional Hybrid Lipid-Polymeric Nanoparticle

In a study titled Multifunctional hybrid lipid-polymeric nanoparticle enabling resveratrol and siRNA co-delivery for enhanced cutaneous wound repair, hydroxyethylcellulose was incorporated into a hydrogel formulation that improved the delivery of therapeutic agents for chronic wound management. The study demonstrated enhanced penetration and retention of the agents in skin, leading to significant improvements in healing.

Oil-in-Serum Formulation for Post-Inflammatory Hyperpigmentation

Another study, Development, Stability, and Clinical Efficacy of an Oil-in-Serum Formulation with Olive Extract Standardized in Hydroxytyrosol for Post-Inflammatory Hyperpigmentation Treatment, highlighted the use of hydroxyethylcellulose in a gel formulation that effectively treated post-inflammatory hyperpigmentation, improving skin hydration and barrier function.

Microneedle Arrays with Hydroxyethylcellulose

Research on The Structural Design and Experimental Analysis of a Microneedle with Microchannels: Capable of Achieving Ultrafast Body Fluid Extraction explored the use of hydroxyethylcellulose in microneedle arrays, enhancing skin penetration and fluid extraction capabilities.

Overall, hydroxyethylcellulose is a valuable ingredient in various formulations, contributing to improved efficacy and user experience.
