    Hi, I recently gain interest in cosmetics/toiletries formulation and would like to hear some guidance. 

    I recently create a formula for baby wash and would like to know whether this is a good formula ?

    Water                                                     73.7% 
    Sodium Cocoyl Glutamate (30%)                12%
    Cocamidopropyl Betaine (30%)                    8%
    Glycerin                                                      4%
    Mthylparaben                                           0.3%
    Xanthan Gum                                              1%
    Citric Acid                                                0.8%

    And how do we calculate the active ingredients for the surfactant ? 
    I tried to thciken the formula with the xanthan gum. However, it doesn’t seems to thicken. Do I need to add more of the xanthan gum ? Or any tips in mixing it ? 

    Thank you for your guidance. :smiley:

    Hi @h_w , have you tried using Peg-120 Methyl Glucose Diolate? It might help your formula to be thicker.

    active surfactant:
    you have 12% SCG, only 30% is active, so final is = 12*0.3 =3.6%
    same for CAPB it’s 2.4%

    if you are adding xanthan gum after surfactant that could be the issue. Add it in before predispersed in glycerin

    Methylparaben alone isn’t a broad spectrum preservative. Rethink your preservative system.

    Hi @zacchaeus, Thank you for your reply. 
    I have read some articles about PEG 120.
    It is said it is good for thickeners however, it is also a cleansing agent. 
    If I add it into the solution, will it increase the active surfactant % ?

    Hi @ngarayeva001, thank you for your reply. 
    If I mix it with propylparaben, will it be a broad spectrum preservatives ? 
    Some baby products only use Sodium Benzoate as their preservatives. 
    Is that considered broad spectrum ? 

    What would you recommend for a broad spectrum preservatives for baby ?

    Germaben II. There are different components that start as PEG-120. Glutamate is very difficult to thicken but you can try crothix liquid. I can’t guarantee it would be very viscous.

    Since this is a simple formula you could just adjust the pH to 5.0 and use sodium benzoate at 0.4%. Methyl paraben is usually combined with propyl paraben, typically at 0.3% + 0.15%.
    This is the best thickener but it’s not cheap. Gums give an unpleasant sensorial.

    I agree with the comments above. Sodium cocoyl glutamate gives a very nice sensorial, but it’s very very hard to thicken. I’ve tried with many thickeners, and the only two that worked for me were Crothix Liquid and Versathix. Also, Glycerin in a rinse-off product is a bit of a waste, since being so water soluble, it’d rather wash away than having a real effect on the skin, so you could also reduce it. I’d also add Propylparaben to complement Methylparaben’s activity.

    @ngarayeva001 @Belassi @ketchito Thank you for your comments. Since SCG is difficult to thicken, will I be able to change the SCG with Lauryl Glucoside as the main surfactant? 

    And I have another discussion about dishwashing liquid. If you guys are willing, can you help me gain some insight. Thank you. :smiley:

    Oh hi, is there a way to increase the spreading ability of the baby wash ? or that depends on the viscosity ?

    Hi! Lauryl glucoside is very effective as a detergent, but it might be too degreasing for a baby wash, especially as a main surfactant. If you want to use a glucoside, use Coco-glucoside instead, and it’d be better if you mix it with a mild anionic, like Sodium cocoyl taurate for instance, of a Disodium lauryl sulfosuccinate which is pretty common in baby products.

    is there a way to increase the spreading ability
    Sensorials depend mainly on two factors. The surfactant and the thickener. You will have to experiment.
