shampoo making

[Guest guest]

Dear Members,

In Shampoo is it necesary to heat all the material at 70 degree and mix and

cool it or the raw materials like CDEA ,SLES 28-70%,SLS,CAPB,COLOR SOLUTION,

NaCl solution and fragrance ane after another at room temperature.

We are heating the water to 70 degree then SLES and SLS is dissoved in the

mixing vessel .In the another vessel we are mixing at 70 degree CDEA , CAB,

POLYQUART 7 etc,When both the temp reches 70 degree we transfer the material

from the vessel containing CDEA,CAPB,POYQUART etc to the mixing vessel .Cooling

it to 45 degee centigrade and then we add presevative and 38 degree we add it

frangrance and salt,citric acid .

My question is whether heating to 70 degree required for making shampoo?

I hope i will get the answer from members .

Thanks and Regards
