Konjac Mannan

Konjac Mannan as a plant gel former

Konjac Mannan is a hygroscopic powder taken from the tuber of the konjac plant, Amorphophallus konjac. In water it swells and binds a large amount of liquid, so it works as a hydrocolloid: a natural thickener that turns plain water into a smooth, elastic gel. It is sold from a 10 g trial pack, which suits makers who want to test texture before they commit to a larger size. The grade and the recommended level are confirmed on the supplier CoA for each lot.

Why makers choose konjac

Many brands want to move away from synthetic thickeners without losing a pleasant skin feel. Konjac gives a cushiony, moist texture that feels softer than many other gums. It also teams up well with xanthan and carrageenan, and the pair often forms a firmer, more elastic gel together than either gum on its own, which lets you use less thickener overall.

Product ideas

Jelly masks and clear or slightly hazy face and body gels are the classic formats. A small amount gives a serum more body, and creams and lotions can use konjac as one part of the thickener system. The dried gel is also the base of the well-known konjac cleansing sponge.

How to hydrate the powder

Sprinkle the powder slowly into water under strong stirring, or pre-wet it with glycerin so it does not form lumps. Allow full hydration time; gentle warming speeds this up. Since the powder pulls moisture from the air, weigh it quickly and close the container. After the gel has rested, check viscosity again and watch for water separating after freeze and thaw cycles.

Partners in a gel range

For extra hydration, combine konjac with polyglutamic acid or the ready polysaccharide gel. The IO Gel-Forming Active Powder is a second texture option. Browse further thickeners and functional powders in our cosmetic actives section.
