THE STORY OF HYDROXYETHL CELLULOSE
Hydroxyethyl Cellulose: The Smooth Thickener for Luxurious Cosmetic Textures
Hydroxyethyl Cellulose (HEC) is a non-ionic, water-soluble polymer used as a thickener, stabilizer, and rheology modifier in cosmetic and personal-care products.
It creates smooth, crystal-clear gels, enhances texture, and improves product stability in serums, cleansers, shampoos, lotions, and hydrogel formulas.
Cellulose-Derived Polymer Modified for High Clarity & Flow Control
HEC is made by etherifying natural cellulose with ethylene oxide, creating a modified polymer that is:
• Fully water-soluble
• Non-ionic (compatible with most actives & surfactants)
• Able to form clear, stable gels
• Excellent for both surfactant-based and emulsion systems
TRCkem supplies various viscosity grades suitable for gel systems, shampoos, lotions, and premium clear formulations.
Thicken. Stabilize. Clarify.
HEC provides multiple advantages in formulations:
✅ Creates smooth, transparent gels
✅ Stabilizes surfactant systems (shampoos, body washes)
✅ Prevents phase separation in emulsions
✅ Enhances spreadability and silky feel
✅ Improves suspension of particles, beads & actives
Used in: serums, gels, cleansers, shampoos, hand sanitizers, lotions, and hydrogel masks.
Easy-to-Use, Safe & Versatile for Modern Formulations
• Typical use level: 0.2–2% depending on viscosity
• Best dispersed in room-temperature water then allowed to hydrate
• Compatible with anionic, cationic & nonionic systems
• Stable across pH 3–10
• Non-irritating, biodegradable & safe for skin and hair
• Store in cool, dry conditions to prevent moisture uptake
• Works well in both cold-process and hot-process formulations
Formulator’s Queries, We Answered
