Among the components used in the manufacture of empty HPMC capsule shells, the most indispensable one is HPMC.

HPMC is a wood pulp derived from softwood species, including pine and spruce. Hydroxypropyl methylcellulose (HPMC) belongs to the group of cellulose ethers in which the hydroxyl groups have been replaced by one or more of the three hydroxyl groups present in the cellulose ring.

Hypromellose is solid, and the appearance is slightly off-white to beige powder. It dissolves in water to form a colloid. This non-toxic ingredient is flammable and can react violently with oxidants.

HPMC is a hydrophilic (water-soluble), biodegradable and biocompatible polymer with a wide range of applications in drug delivery, dyes, paints, cosmetics, adhesives, coatings, agriculture, and textiles.

Some components used in the manufacture of empty HPMC and empty hard gelatin capsule shells include, but are not limited to:

Plasticizers (such as sorbitol, glycerol, etc.)

Plasticizers are added to the capsule shell to reduce the rigidity of the polymer and make it more flexible. The ratio of plasticizer to gelatin in hard gelatin capsules is low, about 0.4:1.

Water

Varies depending on storage conditions.

Sunscreens (eg titanium dioxide)

They provide protection against light and photodegradation. They also function to conceal the contents used to fill the capsule shell.

Colorants (such as dyes, lakes, mineral pigments, etc.)

Colorants can impart various colors to hard gelatin capsules. Colorants play an important role in improving patient compliance and can be further selected to complement the disease being treated.
