COSPHADERM®
XANTHAN GUMS
Our Cosphaderm® Xanthan Gums are 100% natural, COSMOS and NATRUE compliant, vegan, 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 does Cosphaderm® Xanthan Gum consist of?
Xanthan gum is a polysaccharide produced by the fermentation of sugar by the bacterial species Xanthomonas campestris is produced. 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® Xanthan Gums special?
Advantages 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, thus preventing phase separation.
Excellent transparency
The different 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 salts and alcohol
Our xanthans are very salt-tolerant, 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. Only with a further increase in concentration does the viscosity decrease very slowly; 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.
Thanks to the high tolerances, our Cosphaderm® Xanthan Gums can be used in all applications and under all conditions.

All our Cosphaderm® Xanthan Gums are vegan, not genetically modified and are produced by biofermentation of sugars by the bacterium Xanthomonas campestris.
Cosphaderm® X 7
Cosphaderm® X 7 is a cloudy xanthan gum that is not suitable for clear formulations such as water-based serums. It is available 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 for 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 in the advantages of Cosphaderm® X 34 and Cosphaderm® X soft are shown in the following network diagram.
Cosphaderm® X 24
Our Cosphaderm® Xanthan Gums should be added to the water phase of the formulation. For best results, add the xanthan gum to the water phase while stirring.
- In the case of powdered xanthan gums, the formation of aggregates can be avoided by dispersing Cosphaderm ® Xanthan Gum in glycerine or Cosphaderm® Propandiol natural before adding water.
- Salt concentrations above 10% should be avoided
- Ethanol concentrations above 40% should be avoided
- pH values below pH 3 and above pH 11 should be avoided
Dosage
For Cospahderm ® Xanthan Gums, a concentration of 0,1-1,0% recommended.
Storage
The xanthan gums should be stored in a dry, cool environment to maintain stability.
