  • Pearlizer worked once but not now. What are my mistakes?

    Posted by Abdullah on December 24, 2021 at 3:23 am

    First of all i am using a product 28% SLES+ EGDS that i will call pearlizer below. I don’t know and the supplier also don’t reveal the amount of EGDS in product. (any idea how much it would be?)

    Several months ago for first time i made a Shampoo sample with 8% pearlizer and it was a perfect pearl shampoo. I didn’t record the method, only the amount of ingredients. But Because of cost i didn’t use that in my products.

    Recently i wanted to make a pearl shampoo too so again i tried but even with 12% pearlizer and everal samples i couldn’t get a good pearl effect. 

    My formula and procedure of one sample that didn’t give good result. The order of addition is the way i have listed them.
    Sample size was 500g and after adding each ingredient i mixed them with stick blender.

    This same amount of pearlizer did make a pearlized shampoo like big brands the first time i made it several months ago but this time it had almost no effect.

    Water 
    EDTA 0.2%
    Cationic guar 0.2%
    Citric acid 0.25%
    CAPB  1.3%  AS
    Lauryl Glucoside  1.3% AS
    SLES 7.6%  AS

    Xanthan gum  0.2% mixed with 0.3% fragrance and then added
    Pearlizer 8% 
    Formalin 0.15%
    NACL 0.7%  enough viscosity
    pH 4-4.5
    The product temperature during work was room temperature. 

    what is my mistake here that it didn’t work and what should i do to make a good pearlized product?
