Changing Shampoo my Making procedure
Greetings and thanks for watching my discussion
I have about 6 months making regular and sulfate free shampoo using a 35gal steam jacketed kettle, my procedure is just a little standard : adding water, heating it up to 75°c, adding the viscosfier, surfactans and then mixing for about 30 minutes and then colddown to 55-60°c to add the fragance, actives, oils and colorants.But now i just bought a 260gal Stainles steel tank with two agitators (3200rpm and 90rpm) and i want to know if i can use it as a replace for the small jacketed kettle, ussing preheated water from a Industrial water heater (70°C-80°C). is this a standard pocedure in the shampoo or liquid detergernt industry?. -

Wow congratulations, I dream of having a 260 gallon tank!

Thanks @belassi, but having a 260gallon tank its easier that having you cosmetic knowledge.
Btw i bought it very very cheap, the owner was ussing it as a “water tank for his house”, he just bought a barn and the tank was there . so he doesnt know what he had.Do you think that ussing preheated water would work for me?, i mean im ussing the same temperature or maybe more and same water, the diference will be that i cant hold the same temperaure for 30minutes due to heat transfer from the wall of the tank, but i think that 1000L of water will reaming at least 65-70°C for that amount of time, enought to kill some bacterias. -
Yes, you should be able to do that. You’ll need to have a way to cool down the batch though.

Thanks @perry, i was thinking in leaving it into the tank, i was making 6 x 35gal batchs/day , so 18hours of cooldown for 1000liters i consider would be enought , im making a lot of assumptions because i wasnt planing in buying a tank or even making volumes of batchs like that.
I have seen that you say that you have been in shampoo factory , so, it is standard to use preheated water?, or they use cold water and a steam kettle ?. -
We used pre-heated water when making shampoos but only up to about 50C. That was the temperature at which we mixed shampoos because it made the production faster.
All of our tanks had steam jackets for heating and cooling. -
Most plants don’t use pre-heated water, for a couple of reasons:
1) Most formulas call for the use of deionized water. Most deionizing systems produce DI water at a slow, steady rate, and the cost of the system goes up as the rate you need goes up. It is much more cost effective to buy a low-rate system, have it running most/all of the time, and have the DI water feed into a holding tank that will let you quickly pull off much more water for a batch than you could if you were relying on the flow rate of the DI system alone. Systems like this have to be flushed and sterilized regularly. Installing a pre-heat tank into this type of system adds another layer of complexity, and even more equipment that needs to be sterilized.2) Steam heating is relatively fast, so time isn’t much of an issue. And if you already have steam heating installed, it just doesn’t usually make economic sense to install a pre-heater if there’s not already one in place. Also, the cost of keeping unused water hot for a long time (overnight or over the weekend) may work out to be greater than the cost of waiting for the water to heat up.For a brand new installation, however, pre-heating in a tank or even better, using an on-demand heater, might be a worthwhile investment. There’s no chemical reason not to do this, it’s all decided on a cost basis. -
Thanks @bobzchemist your explanation helps me a lotWe were willing to buy a small reverse osmosis filter and do exactly what you said, but our daily water consumption its about 500gal Day and there arenot suppliers that have atleast 300g/day filter available in my country, so the only option is to buy one in USA but taking it into my country its kind of dificult.Right now we are using regular tap water passing through 15,10, 5 microns membrane filter and activated carbon, and holding it for 30min at 70-80 celcius degrees using the jacketed kettle but making 6x 35gal batches of shampoo and 6x 35gal batches of conditioner mostly per day its kind slow and time consuming.we already have a industrial Gas on-demand heater that supply 8gal/minute at 70-80°C and its cost reasonable, asuming that in our country he price of a can of Coke is equivalent to 50gal of Butane/propane.Your answer let me know that we are not doing crazy things
