  Which of those ingredients have you seen in a shampoo's list of ingredients?

  Thanks @Perry and @Belassi. I haven’t seen those ingredients in any shampoo label actually, I am trying to effectively help the Carbocystein to penetrate into the hair for straightening application.

  it is not a simple ingredient, but a mixture:

  For hydrophiles such as carboxylol cysteine, you may consider ethoxydiglycol (glycol ether DE). It is cheap too. For lipophilic components, dimethyl isosorbide works very well as a penetration enhancer. Still don't know why it remains so expensive after all these years either.

  What about carboxylic acids?

  Thanks @jeremien!
  
  @chemicalmatt thank you, honestly I do believe that Dimethyl Isosorbide can do a great job but I’m still considering trying it because of the price. Croda sells this ingredient under the name Arlasolve and it’s super expensive. I will look into the Ethoxydiglycol, thanks again!
  
  Hi @Gunther, I actually contain one carboxylic Acid in the formulation, is there any specific Acid you should recommend? And thanks for your comment, I appreciate that.

  @Lisani
  You can try cetrimonium bromide if you want to penetrate into cortex.
  Also as perry advice coconut oil is one of the natural oil that can penetrate into.
  
  But if you are seeking damage repair and some conditioning you've better try low particle size hyrdolyzed keratins like Nutrilan Keratin(BASF)
