I don't what's going on with my liquid soap formula, I need a help, please

Hello,

I tried to do some formulation for my hand liquid soap and I found one in the Internet, but unfortunately, I wasn't satisfied with the overall quality of the liquid soap when I compared it to the market liquid soap e.g. lux hand liquid soap. Here is the formula that I used, and I need your help to develop the thickness of the liquid and to enhance the moisturizing effect with the perfect color, please. I don't know exactly about the problem with this formula, but I did not feel it to b like the quality of the market soap.

Sodium Lauryl Ether Sulphate (SLES) = 10 kg
Cocamidopropyl Betaine (CAPB) = 5 kg
Cocamide Diethanolamide (CDEA) = 2 kg
Glycerin = 1 kg
Preservation (Formalin) = 0.15 kg
Dye = 0.05 kg
Perfume = 0.15 kg
Critic Acid = 0.5 kg
Sodium Chloride = 2 kg
Water = 79.15 kg

I really appreciate your help.

  • Formalin? Are you serious? That's a banned substance.
    There is insufficient surfactant.

  • Assuming the SLES is 30% (or thereabout), this level of prime detergent is very low and out of proportion to the CAPB and CDE.

    In addition, the level of sodium chloride is too high for such a low level of detergent. This is likely to result in a low viscosity and a high cloud point. The sodium chloride level should be adjusted  each time and in a mix of the three main detergents you have, it may not be required at all.

    Actually Azeez, your primary problem is the glycerin.  An infamous killer of viscosity and foam.  TAKE IT OUT and you'll be fine.  All the salt in the mine won't build your viscosity with that in there.  It tickles me to no end that everybody puts glycerin in their liquid soaps and shampoos.  It does not and will not deposit on the skin or hair. Glycerin is not a re-fatting agent like PEG-7 Glyceryl Cocoate or Sorbitan Oleate, etc., etc.
  • Thank you Belassi for your comment. Can you provide me with an appropriate preservation material with its quantity that can be used instead of formalin ?
  • Thank you Johnb for your comment. That's exactly what I got with my liquid soap, a low viscosity with a cloud color. Can you give me an estimate for the recommended weights of each material, please ?

    I am a beginner in the field of soap making processes and I really need your help guys !
  • Thanks Chemicalmatt for your comment. I think Glycerin is an important factor in increasing the moisturizing effect in the soap. Is there any other alternatives that can be used instead of Glycerin ? and at what quantity ?
  • At least double the amount of SLES.
    Omit the sodium chloride, at least until the product is thoroughly mixed and then add a small amount at a time until you reach a suitable viscosity. The amount added will be much less than the 2% you are currently using and you may not need any at all (this would be the ideal).

    Regarding the addition of glycerine or other moisturisers, it is a waste of time and money as Chemicalmatt says.
  • Choice of preservative depends on many factors, not least the availability in your market. Using sodium benzoate at 0.5% is generally sufficient but the pH must be 5 or less.

  • Perfect ! Can I say that the following formula is better and can be used ?

    Sodium Lauryl Ether Sulphate (SLES) = 22%
    Cocamidopropyl Betaine (CAPB) = 5%
    Cocamide Diethanolamide (CDEA) = 1.75%
    Preservation (Sodium Benzoate) = 0.15%
    Dye = 0.05%
    Perfume = 0.15%
    Critic Acid = 0.5%
    Sodium Chloride = 1.75%
    Water = 68.64%


  • Please heed my comments re sodium chloride (above).
  • No one can say if this formula is correct. It is necessary to make it and test it. As @johnb noted. Do you understand the term "salt curve"? Know about micelles and their structures?

    About glycerine: I have been informed by my suppliers that glycerin reduces the irritancy of SLES or SLS, working synergistically with cocamidopropyl betaine. It may not be a refatting agent but will give a milder final product.

    Instead of Sodium Benzoate you could also use DMDM Hydantoin.
  • Sodium Lauryl Ether Sulphate (SLES) = 22%
    Coco betaine (CAPB) = 5%

    --------- premix
    poly 20 = 0.30
    Perfume = 0.15%
    --------- add to batch

    Preservation (glydant +) = 0.15%
    Dye = 0.05%
    Critic Acid = qs%
    Sodium Chloride = qs%
    Water = qs%

    tada!


  • Hello chickenskin : the SLES as que made reference is  SLES  30%?

  • What if we use 70% active SLES in formula 
  • bil7bil7 Member
    Used 70 percent sles at 7 to 8 percent and sls powder 1 to 2 percent and Cocobetaine 2 to 3 percent. 
    I dnt see Naoh in your formula how you saponify your fat. It requires at 0.5 percent put in it also provides you better with thickness and working performance. 
    No matter of 0.2 percent glycerin cant do anything. 
  • bil7bil7 Member
    Also add .2 percent edta will work out properly and citric acid .04 to .6 percent
