Thicken my soap and some more questions

[Ashraf Emam]

Hi wonderful group
I have some questions and I need your experience,..
1- What replaces the sodium benzoate and gives a long shelf life?
2- If there's no replacer for it, what is the safe ratio?
3- If I am going to use EDTA , what is the safe ratio?
4- How to thicken my liquid soap (is it the water to soap paste ratio only or should I add sodium cloride and cetric acid?)
Thank you in advance and really appreciate your help.

1. See: Liquid Soap Preservation : Sodium Beozoate and also Preservative Reviews

2. Some people don't use a preservative at all in diluted liquid soap. Others use a general broad spectrum preservative rated for high pH, such as Suttocide, Liquid Germall Plus, or Glydant Plus. Source: Preservative Reviews

3. See: Table of contents | Soapy Stuff

4. The method of thickening depends on your goals and the specific type of fatty acids in your soap. Do NOT add acids for the purpose of thickening soap. More: Table of contents | Soapy Stuff

Thank you very much for these useful information, I found out that using rosemary extract can replace the sodium benzoate. is it true?
Plus.. I will add several oils in the mix, coconut, olive, sunflower, sesame, castor, I actually don't know how it will behave in the batch .. Why I am not go simple first, because this is me exaggerating to achieve goals faster

1- What replaces the sodium benzoate and gives a long shelf life? - I do not use this.
2- If there's no replacer for it, what is the safe ratio? See DeeAnna's response

4- How to thicken my liquid soap (is it the water to soap paste ratio only or should I add sodium cloride and cetric acid?) See the following:

Sodium Chloride (common table salt) is used to thicken 100% Olive Oil Castile and similar LS. It will not thicken formulas that contain more than 20% coconut oil and similar LS formulas.
Citric Acid (20% solution) is not a thickener. It is sometimes used to neutralize excess lye. Since I soap at 0% SF, I add it to lower pH. Use rate: 0.06%. Warm before adding to warmed LS. Typically, it “flakes out”. Warm the batch to 140°F and gently stir to incorporate. Citric acid can also be used to create sodium citrate which functions as a chelator similar to EDTA. Both are optional ingredients.

IME and IMO formulas with 50% coconut or PKO + 50% liquid oils of choice have the best viscosity -- similar to shampoo. Dilution Rate: 40% soap to 60% water.
