  sequestering agents recommended range for soap products

  Posted by leather_suds on March 28, 2019 at 2:05 pm

  Hi Everyone!

  I am re-evaluating the chelates used in my soap formulas.

  I have been using a combination of EDTA, tetrasodium etidronate and pentasodium pentetate at an approx. range of 0.25% 

  Depending on the chelate used, I assume the ranges would vary to achieve the same level of performance.

  I have been searching the web for literature stating recommended ranges for chelates without much success, perhaps my searching choices are not the right ones, which is why I am turning to you for advice

  Anyone has a source with recommended ranges for the following chelates in soap formulations:

  -Sodium Citrate
  -Tetrasodium Glutamate 
  -EDTA
  -CItric Acid 

  Thank you!

  to be more specific… can I get away with using sodium citrate at 2% in my soap formulas? I have been using it at 0.25 and it does nothing. A colleague mentioned that in detergents it’s used at up to 9%. I did some trials and at 2% its working good… don’t seem to have affected anything else yet… can I get away with this?

  Since I have no idea what is in your ‘soap’ I can’t comment.

  I am new to the forum!
  I should have included a breakdown of my formula, sorry about that
  My formulas are very simple and look something like this in general terms:

  Sodium palm kernelate base 96%
  titanium dioxide 0.5%
  frag 1%
  emollients 2%

  my base already has chelate @ approx. 0.15% (etidronate and EDTA) 

  is there a recommended chelate range in general for soap products?
