Make sure you are using a Cosmetic Grade Guar Gum or Cationic Guar Gum as regular guar gum is susceptible to microbial attack and hence the loss of viscosity. Would also be a good idea to use a biocide.

@ perry-We put 2% into the water and mix, after that add citric acid and guar gum makes a gel. This solution we add into anionic surfactants (SLES 27% and another kind SLES 70% - in formulation with vegetable oils). After this add other ingredients as betaine and cocamide DEA.

Dose in final formulation of shampoo is 0,5%. 

We don’t notice any problem during production. guar is dissolved and looks the same as previous formulation and we do not notice any problems. Problems we see one day after production. 

We also tried change the order of adding the ingredients by adding first the cationic then the amphoteric then non ionic and lastly the anionic but the result is same. 

We like to new guar better, it has better conditioning but do not understand how to make it work in formula

Hi, yes, it is new Guar HPTC supplier. The formulation is same. We made sure that product is dispersed properly and completely hydrated. After many days of holding the solution, the guar settles down as a very thick gel. 

We are using a pre neutralised guar product.
