Reading the INCI names of surfactants NEW!

What does it mean for something to be cationic, anionic, or non-ionic? New!

Surfactant types
Alkyl sulfates– like sodium lauryl sulfate (SLS)
Alkyl ether sulfates – like sodium laureth sulfate (SLeS)
Amide ether sulfates
Alkyl glyceride sulfates
Alkyl sulfonates  – like C14-16 olefin sulfonate
Alkyl-aryl sulfonates
Sulfosuccinates– like disodium laureth sulfosuccinate or DLS
Fatty acid isethionates– like sodium cocoyl isethionate (SCI)
      A few notes on SCI
Taurates or taurides – like sodium methyl cocoyl taurate (SMC taurate)
Phosphate esters
Acyl-amino acids & salts
Sulfoacetates – like sodium lauryl sulfoacetate (SLSa)
Betaines – like cocamidopropyl betaine
Alkyl polyglucosides or glycerides – all kinds in here from decyl glucoside to PEG-7 glyceryl cocoate
Ethanolamides or alkanolamides– like cocamide DEA
