Thanks! I tried this process but after some time shampoo looses its viscosity. I am using acrylates copolymer as a thickner. Other ingredients of shampoo are ammonium lauryl sulphate, CAPB, CDEA, EGMS, clotrimazol, phenoxyethanol and fragrance, Triethanolamine.

I check the compatibility data of elastomer, there is no compatibility issue of all the ingredients with elastomer.

Thanx @Bobzchemist

List of denatured spirit is you provided helps to solve the problem.

I tried IPA but according to me, the drying rate of IPA was less than ethanol.

Thanks! We are trying both ways i.e. W/O and O/W. However we now achieved O/W emlusion with matt finished. Now working on the stability part as its losses its viscosity after 8 days on 45 degree C/75% RH.

Thanks! The link you shared is helpful.

The bechmarks have different emulsifier system. I tried with that system also but it didnt work so that’s why I changed the system. Now we achieved the sensorial part as per our requirement but still struggling with stability.
