Are you part of 'sulfate-free' movement as well? Or are you facing challenges to be one?

The term of ‘sulfate-free’ products is the latest talking point in the personal care industry.  Over the past 7 years, one of the consumer’s concerns have been over the use of alkyl sulfates and alkyl ether sulfates, and it has been growing significantly. As we know that the natural, organic and mild ingredients are starting grow as the market demands has grown in this year. The attempt to replace sulfates in personal care products continues to gain momentum globally. This is even more so as the market leaders are bringing an increasing number of sulfate-free formulas to the mass markets. But, economies will never support the elimination of sulfates in personal care products. As the solution, the formulators sometimes develop products with “partially replacement of sles”concept to minimize the price.

How to formulate the stable 'Sulfate-free' products?

There are some tricks that can be used to develop ‘sulfate-free’ formulation that is acceptable to customers. Below are some of the tricks that you should to know :

  1. Choose a surfactant, preferably more than 2 surfactants from betaine, amphoactetae and alkyl polyglucoside group as a foam booster.
  2. Choose a non-ionic surfactant from alkanonol amides, alkyl ether, and glyceryl esters group to keep foam stability and enhance the product’s viscosity.
  3. Add thickening agent such as NaCl, PEG N-Distearate, Acrylates Copolymer, Xantan Gum or Hydroxyethyl cellulose to increase the viscosity.

Refer to the chemical groups that we mentioned above from the table shown below:

Betaine Group Amphoacetate Group Alkyl Polyglucoside Group
  • Cocamidopropyl Betaine
  • Coco-betaine
  • Sodium Lauroamphoacetate
  • Sodium Lauroamphodiacetate
  • Luryl Glucoside
  • Decyl Glucoside
Alkanol Amides Group Alkyl Ether Group Glyceryl Ester Group
  • Cocamid DEA/MEA
  • PPG-2 Hydroxyethyl Coco/Isostearamide
  • Laureth-2
  • Laurylglycol Hydroxyethylether
  • Glyceryl laurate
  • Glyceryl Caprate
