Hydroxypropyl Methyl Cellulose – Walocel HM FG

Wolff Cellulosics is the center of excellence for cellulose chemistry within Covestro. Its cellulose derivatives are used as additives for building materials and as raw materials for printing inks and surface coatings. High-purity cellulose derivatives are also used in food products, cosmetics and pharmaceutical products. At its state of the art pilot plant, Wolff Cellulosics develops new products and technologies for the production and processing of synthetic derivatives of the renewable raw material cellulose.

What is Walocel HM FG

Hydroxypropyl methylcellulose is manufactured from high purity cellulose in compliance with GMP and HACCP. In codes and regulations this product is also known as HPMC, E464 or modified cellulose.

Walocel® HM FG products meet all requirements of the Code of Federal Regulations of the Food and Drug Administration (FDA) Part 21 CFR 172 874, the FCC and the EU Directives for E 464 in their current version.

Walocel® HM FG are not subject to Regulations EC 1829 and 1830/2003 and can be regarded as free of genetically modified organisms.

Characteristics of Walocel HM FG

  • Controls the rheology of aqueous solutions
  • Gelling aqueous solutions ≈ 60° C
  • Compatibility with all other hydrocolloids
  • Good freeze/thaw stability
  • High water binding capacity
  • Dissolves at low temperatures
  • Replaces fat and protein in many applications
  • Effective in very acidic systems (>pH 1)
  • Has absolutely no odor or taste
  • Very stable in systems with high salt content

Walocel FM HG Description

Walocel® HM FG products are hydroxypropyl methylcellulose, which are defined by:

  • The degree of substitution (content of methoxy and hydroxypropoxy groups)
  • The degree of polymerization (length of the cellulose chain)
