Gelatin Capsules Containing PEG — QUALI-G™-PEG

Product Overview

  • Gelatin capsules to which polyethylene glycol (PEG) 4000 equal to 5 wt% is added as a plasticizer.
  • Mechanical strength of this type of gelatin capsules under low-moisture conditions is much greater than that of standard gelatin capsules.
  • Dissolution property of this type of gelatin capsules is the same as that of standard gelatin capsules.
  • Registered on Drug Master Files for the US and Canada.
  • Manufactured in a validated continuous production environment in compliance with Good Manufacturing Practice (GMP).
  • High-quality raw materials in conformity to the JP, the EP, and the USP/NF for specifications are used.
  • Preservative-free.
  • Suited to filling with hygroscopic APIs.
  • It is possible to fill with a combination of two or more types of preparations, such as solid, oily liquid, and semi-solid preparations (oily liquid and semi-solid preparations need the band sealing).

Capsule Colors

Capsule Colors

Hard capsules have the advantage to enhance their distinguishability.
Various capsule colors can be made upon request.

Capsule Printing

More than 90% pharmaceutical capsules made in Qualicaps® are imprinted to enhance distinguishability.

Two imprinting methods are available:
・Offset printing with various color ink
・UV lazer printing with no ink : Qualicaps®'s own technology

Offset printing

Offset printing uses edible ink,
in which various colors are available.

Offset printing
UV lazer printing

UV lazer printing technology utilizes the color change of titanium oxide by UV irradiation.
UV lazer can print fine design to capsules.

Test Data

Dissolution Test

QUALI-G™-PEG capsules, as same as QUALI-G™, have excellent dissolution properties, with not less than 80% of the capsule contents released within 5 minutes.

Test Data

Test conditions

Capsule size: ♯3

Apparatus: Paddle method, 50 rpm, UV detection

Dissolution medium: water, 900 mL

Capsule fill formulation: 20% acetaminophen mixture

Fill weight: 200 mg

Brittleness Test

Capsules are evaluated by pressing 100 capsules at 60 PSI for 15 seconds in a dedicated testing apparatus and checking for broken capsules.

QUALI-G™-PEG capsules are more resistant to brittleness than QUALI-G™ capsules when compared at the same moisture content, which is an
advantage when handling hygroscopic APIs.
