I do agree with Perry, It may be due to oil soluble perfume or any of the oil ingredients, solubilizer may be needed here like PEG-40 hydrogenated castor oil or Polysorbate etc.

Thanks @Bill_Toge , it is packed in vacuum sealed pouch &
kept for stability but colour of product changed at accelerated temp., All incorporated ingredients are powder form only. Is any of the suitable anti-oxidant available which should prevent discoloration during shelf life of product?

I need stabilizer for peroxide salt because finished product (Powder hair colour) is getting oxidized at accelerated temp. (during stability). Sorry for delay…..

I have done a knockout experience but still not got solution. I know it is difficult product to make. But, i don’t want the proposed product to resemble shaving cream, it should rinse faster from face.

Then why don’t u use carbomer ready made dispersion which are Acrylate copolymer, they are easy to mix even with less air entrapment & moreover cheap also.

Thanks Belassi, @David, it’s a saponification system, really do we need emulsifier, i used Glyceryl
stearate & PEG-100 stearate (Emulsifier) just due to one of our competitor used it.

Even Non ionic surfactants are also advisable and stable at wide range of pH & also these are eco-certified but for organic claim need check with supplier. Please refer BASF range of Glucosides.

Try to soak carbomer for 15-20 mins. in water and then stir slowly. It may be helpful.

For making an emulsion, one should use enclosed system which would prevent evaporation of water to a certain extent or on basis of experience of preparation of 1 or 2 batches, chemist should take extra water to make up losses.

For advantages, please refer google.com & not necessary to add ethanol as you can add solubilizers for Salicylic which would be Glycol groups e.g. PG, Butylene G, Hexylene G ….etc
Note - 1, 2 hexandiol is preferable.

I do agree with @Bobzchemist, formulator should search on google first and if He or She is not getting any answer then raise a query on Chemist corner. For starting formula, new comers should refer Prospector.com (as suggested by Perry). Natural means? fully or partially? or actives would be natural? please elaborate…….

December 23, 2015 at 9:30 am in reply to: Overmixed Shampoo - How to Save Batch

@Perry, I made shampoo under vacuum as it will form less foam than open system. I think, if you control vacuum in vessel, you will be able to solve problem of more air entrapment. I do agree that foam will form in any surfactant system whether under vacuum or not but vacuum will solve a bit.
