COSPHADERM® XANTHAN GUMS
Our Cosphaderm® Xanthan Gums are 100% natural, COSMOS- and NATRUE-approved and vegan, are easy to incorporate and create highly stable, transparent formulations. Thanks to their pH-independent applicability and compatibility with salts and alcohol, they open up a wide range of application possibilities for formulations that do not leave a sticky feeling on the skin. They have no effect on the taste, colour or smell of a formulation.
What are Cosphaderm® Xanthan Gums made of ?
Xanthan Gum is an polysaccarid, produced by fermentation of sugar by the bacterial species Xanthomonas campestris. It consists of a main chain of β-D-glucose, supplemented by β-D-mannose and α-D-glucuronic acid side chains.
What makes Cosphaderm® so special ?
Benefits of Cosphaderm® Xanthan Gums
Emulsion stabilising
Compared to standard xanthan gums, our Cosphaderm® Xanthan Gums are much better at stabilising the coalescence of oil droplets in O/W emulsions and thus prevent phase separation.
Excellent transparency
The various Cosphaderm® Xanthan Gums do not clump together, produce a clear solution and dissolve very quickly in a highly viscous structure. Comparable products on the market often have problems such as clumping, clouding or longer processing times.
Tolerant to salt and alcohol
Our xanthans are very tolerant to salts, which can play a decisive role when using anionic surfactants and electrolytes. With an initial increase in concentration up to about 1% NaCI in the solution, the viscosity is even increased. The viscosity only decreases very slowly with a further increase in concentration, up to very high salt concentrations of around 10% NaCI. Cosphaderm® Xanthan Gums are also stable up to a concentration of 30-40% ethanol.
pH stability
A unique feature of our Cosphaderm® Xanthan Gums is that the pH value has no influence on the viscosity. Even extreme pH values between 3 and 11 can be formulated.
Due to the high tolerances, our Cosphaderm® Xanthan Gums can be used in all applications and under all conditions.

Cosphaderm® X 7
Cosphaderm® X 7 is a turbid xanthan gum which is not suitable for clear formulations such as water-based serums. It is in powder form and is particularly suitable for emulsions.
-
Cosphaderm® X 24
Cosphaderm® X 24 is a powdery, transparent xanthan gum and is therefore suitable for clear formulations as well as emulsions or surfactant-based formulations.
-
Cosphaderm® X 34
Cosphaderm® X 34 is also a transparent xanthan gum and is suitable for all types of formulations. Due to its special granular structure, it is less dusty to process and has a faster water solubility.
-
Cosphaderm® X soft
Cosphaderm® X soft is, as the name suggests, a xanthan gum with a particularly soft skin feel. It is transparent, suitable for all types of formulations and its special sensory properties result in less stickiness and a soft skin feel.
The difference of the properties of Cosphaderm® X 34 and Cosphaderm® X soft is shown in this spider chart.
