@Perry here it says “Nitrosamines may be formed in cosmetic and personal care products only if they contain both an ingredient that acts as a Nitrosating agent and an amine ingredient”.

What is Nitrosating agent?

Does it mean all amines( cocamide DEA, MEA, MIPA, Methyl MEA) or some of them specifically?

@chemicalmatt if MEA is the the problem then why cocamide DEA is banned and everyone is seeking alternative for it instead of cocamide MEA?

@ngarayeva001 for me betaine even at %15 active doesn’t clean hair enough so there may not be much different between quantity of betaine and SCI

@Zara do you know how to use HEC?
It is water soluble and can mix very easily buy after mixing you have to increase the pH to 8-10 for it to get thickened. And then you can decrease the pH back.
Decyl glucoside is very hard to thicken and you would need more HEC. Lauryl and coco Glucoside is not so difficult.

@Padmavathi so you are also using it for label not for function?

Hydroxypropyl Methylcellulose is not compatible with Glucoside but Hydroxyethylcellulose is in my experience

Does amphoteric surfactant increase the viscosity of Sodium Lauroyl Sarcosinate or Sodium cocoyl Isethionate?

@EVchem i made a Shampoo with %1 Stearamidopropyl Dimethylamine and you can feel more condition and less buildup in first use compared to same formula with %0.2 cationic guar.
It is very thick an no separation after 4 days. I want to know if this separation for other people happened when formulating, after some time or they haven’t tried it by themselves

@Perry @EVchem when will this interaction and separation happen?
During Shampoo making or after some days and months?

@Perry what do you mean by don’t work?

Will it not clean the hair?
Will it not condition the hair?
Will the formula separate or something?

What would be the exact problem?
