HEC Daily Chemical Grade

-- Steady & Reliable Manufacturer --

Brief Product Description

Daily chemical grade Hydroxyethyl Cellulose (HEC) is a high-purity, non-ionic thickener and stabilizer formulated for personal care and household products. It is widely used to control viscosity, improve texture, and suspend active ingredients in shampoos, conditioners, body washes, face washes, and household cleaners.

Product Overview

EASONZELL™ HEC Daily Chemical Grade is manufactured to stringent purity standards with low residual salt and heavy metal content, meeting the quality expectations of leading personal care brands. As a non-ionic polymer, it is uniquely compatible with the wide variety of surfactants, conditioning agents, and preservatives used in modern cosmetic formulations — whether anionic, cationic, or amphoteric.

Unlike synthetic thickeners, HEC imparts a light, non-greasy skin feel and does not interfere with the biological activity of active ingredients. It is readily biodegradable and aligns well with the industry trend toward naturally-derived, sustainable formulation ingredients. Our daily chemical grades are available in a range of viscosities to suit low-viscosity toning lotions, medium-viscosity shampoos, and high-viscosity styling gels.

Application

EASONZELL™ HEC Daily Chemical Grade is suitable for the following product categories:

  • Shampoo and conditioner — primary thickener providing body and stable viscosity across temperature changes.
  • Body wash and shower gel — imparts a pleasant, non-slimy skin feel with excellent foam stability.
  • Face wash and cleansers — low-irritation thickener compatible with gentle surfactant systems.
  • Hair styling gels — high-viscosity grades provide strong hold with clear, transparent gel appearance.
  • Household cleaners and detergents — stabilizes surfactant systems, prevents phase separation.
  • Liquid hand soap — provides rich, smooth lather and elegant pour viscosity.

Usage notes: For optimum dissolution, disperse HEC powder into water under moderate agitation before adding salts or other electrolytes. Avoid adding directly to surfactant concentrates. Compatible with NaCl-based thickening systems when added in sequence.

Advantages

  • Broad surfactant compatibility — non-ionic nature ensures stable performance with all surfactant types (anionic, cationic, nonionic, amphoteric).
  • Clean skin feel — no tacky or greasy residue; leaves hair and skin feeling soft and lightweight.
  • Excellent salt tolerance — viscosity remains stable in the presence of NaCl and other common electrolytes.
  • High purity — low heavy metals and residual salts meet or exceed INCI grade requirements.
  • Sustainable origin — cellulose derived from sustainable wood pulp; readily biodegradable by OECD 301 standard.
  • Wide viscosity range — a single portfolio covers lotion, shampoo, and gel viscosity targets, simplifying supplier management.

Frequently Asked Questions

  • Q: What is the INCI name for HEC and how should it be declared on cosmetic labels?
  • A: The INCI name is "Hydroxyethylcellulose." It should be listed in the ingredients (INCI declaration) of the finished cosmetic product in descending order of concentration, in compliance with EU Cosmetics Regulation (EC) No 1223/2009 or equivalent local regulations.
  • Q: Is daily chemical grade HEC safe for use in rinse-off and leave-on products?
  • A: Yes. HEC has a long history of safe use in both rinse-off (shampoo, body wash) and leave-on (lotion, cream, styling gel) products. It is non-irritating, non-sensitizing, and has been reviewed favorably by the Cosmetic Ingredient Review (CIR) expert panel.
  • Q: How does HEC compare to carbomer as a thickener in personal care?
  • A: Carbomer provides very high viscosity at low use levels and creates a clear, gel-like texture, but requires neutralization and is sensitive to electrolytes. HEC is easier to formulate with, electrolyte-tolerant, and produces a lighter texture — making it preferred in surfactant-based systems like shampoos where carbomer's electrolyte sensitivity would be problematic.
  • Q: Can HEC be used in natural or organic certified formulations?
  • A: HEC is a semi-synthetic, cellulose-derived ingredient and is accepted in many "natural" positioned formulations. However, acceptance in certified organic systems (COSMOS, NaTrue) depends on the specific standard and certifier. Please review the applicable standard with your certification body.
  • Q: Does HEC affect the transparency of clear shampoo or gel formulations?
  • A: Standard HEC grades may introduce slight haziness in highly transparent formulations at high concentrations. For crystal-clear applications, we recommend our low-ash, high-purity HEC grade, which minimizes turbidity. Trial formulation testing is advised.
  • Q: What documentation is available for cosmetic regulatory compliance?
  • A: We provide full technical documentation including Certificate of Analysis (CoA), Safety Data Sheet (SDS), heavy metals analysis, REACH compliance declaration, and where applicable, BSE/TSE-free declaration. Samples for your stability and safety testing are available upon request.
