I'm a beginner . Got this recipe from a tutor who taught me recently:
One-and-a-half liters of Sulphonic Acid
1/4 kilo of Natrosol
1/2 kilo of Texapor
1/8 liter of fragrance
1 kilo of STPP
1/2 liter of Formalin.
We used a small quantity as sample for my training. I've made some myself afterwards. But it leaves me wondering what those ingredients uses are. Besides the fragrance, i've no clue what the others purposes are neither does my 'trainer' .

I would love to consult all this self-acclaimed experts but i've realised something after spending a lot consulting them: they're only more knowledgeable than their students by A HAIR'S BREATH.
