ALTER-GELIJAC

A gelling agent allowing high viscosity, plant alternative to carbomer.
Ideal to obtain colorless gels with hight viscosities.

ALTER-GELIJAC is a natural, plant-based gelling agent that produces translucent, high-viscosity gels.

It is a perfect alternative to synthetic polymers. This ingredient is obtained by extracting polysccharides from the konjac’s root. It leaves a protective film on the skin and a freshness feeling. It can be used both hot and cold.

Manufacturing process :

Alter-Gelijac – Konjac’s roots

• Natural fiber obtained by extracting polysaccharides from the roots of the Amorphophalus konjac plant which is traditionally harvested in China. The powder obtained is mainly composed of glucomanan, a composition of two sugars: mannose and glucose.

Function

• Gelling agent for aqueous phases allowing high viscosities.

Composition
: ALTER-GELIJAC is mainly composed of glucomanan (>> 85%), a composition of two sugars: mannose and glucose.
Gelling by water molecule retention.
It requires no pH variation, no electrolytes, no heat.

• Thickening effect in the presence of electrolytes
  ALTER-GELIJAC can thicken media containing some elecrolytes.

• Viscosity according to amphotere surfactant
  ALTER-GELIJAC is compatible with Amphoteric surfactants untill 10%

Graph n°4 : viscosity of a 1% ALTER-GELIJAC gel according to the quantity of amphotere surfactant ; The test was carried out with « cocamidopropyl betaine » surfactant.

• Viscosity according to non ionic surfactant
  ALTER-GELIJAC is compatible with non-ionic surfactants untill 10%.

• Viscosity according to anionic surfactants
  The gel’s viscosity obtained doesn’t change over time;
  We observe a change in the gel’s appearance with 20% anionic surfactant concentration. The gel becomes more slimy.

• Viscosity according to cationic surfactant
  ALTER-GELIJAC can thickens media containing cationic surfactant.
  The viscosity of the gels obtained doesn’t change over time.
