  You’ll have to experiment with ratios of SLES : CAPB : Cocamide DEA

  @Perry What ratio would have lower stringiness? 
  Which one to increase or decrease?

  I can’t really give you an answer on that because the ratio depends on a lot of factors including the composition of the materials you buy, the manufacturing conditions, the composition of the other ingredients in your system and your particular definition of “stringy.”

  You have to experiment. 

  Right now your ratio is about 12:2:1
  So, try 15:2:1
  Then try 9:2:1 
  And see what you get.

  Or try 12:2:2  then 12:2:0… etc.

  Formulating rarely has some simple answer. It’s why people still hire cosmetic chemists rather than just buying a recipe book.
