    Not one ingredient but several. Two anionic surfactants plus one amphoteric surfactant, depending on mass ratios, will make a viscous solution. Beef that up with Polyquat-10 and you build more. Finally adding electrolytes (sodium citrate/citric acid) and it builds even more. Glycerin beats it back down.

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

    Abdullah: affirmative. That ampho works in synergy with the anionics you mentioned to build viscosity.

    Some varieties of polyquaternium-10 create gum-like viscosity (they vary a lot btw, always test). But there’s something I find a bit surprising in this shampoo, amphoteric goes first and SCI is high up. It’s rarely used at a high % in liquid products.

    @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
