    Thanks @fareloz @Abdullah for the feedback. I decided to swap SCI for Sodium cocoyl glutamate.

    @Zoya

    Any particular advice on the procedure? Sometimes I don’t know why I get crystalization. What I do is… I heat the SA with propanediol 1:15 ratio and then I mixed it with water and rest of ingredients.

    Regards.

    Thank you. I have used successfully ratio 1:15 with propanediol. I wanted it to try with butylene glycol because I seen the combo sa +butylene a lot. Does anybody know what would be the advantages of butylene glycol over propanediol?

    thanks for replying back.

    I don’t know if I have explained myself correctly, the dropplets don’t appear on the top of the product, but in the surface of the plastic bottle. I am experiencing condensation of the water content of my cream.

    I have xanthan gum and guar gum so I could try adding one of them. But I would like to understand why or how could be ta thickener solution? Would they act like a water trap? (sorry If I sound stupid).

    What I do is heat both oil phase and water phase for 20´low heat, then I add some water to compensate the water loss. After I pour the water phase into the oil phase and I blend with stick blender until the emulsion is formed. I stir from time to time until is cool and I add the preservative and lower the pH. Then I let the product sit all night and store it next day.

    Thanks for the replies 🙂

    Apologies for not mentioning that… I use 0,2% EDTA, 3% glycerine and shea butter is refined.

    This is my first time ever using this fragrance and this preservative system. I thought about using Germall Plus but I can’t use it in Europe. That’s why I wanted to give a shoot to this combo and see if it works for me. What I have learned in this group since joining it’s to use antifungi+antibacteria+ chelant

    The cream that I normally use, before becoming a DIY, it’s Eucerin. This cream has a 5% panthenol, pH 5 and fragrance in a jar.

    I removed EDTA and that did the trick. The emulsion is stable either way using NaOH or EDTA. Granules appear when I use both. I think both react or the higher the pH the more EDTA messes around.

    Now I wonder if Liquid Germall plus at .5% is enough or chelant is a must in my recipe.

    easiest thing to do it’s to add a rosemary or lavender hydrosol or you have already oils so you could add essential oils as well with the solubiliser you are using.

    I am among the folks that cant afford too much testing. I try to play it safe and I can’t thank you enough for your help. My go preservatives thanks to you are Phenoxy/EHG with some sodium benzo and EDTA; euxyl k 700 ( combo of phenoxy, benzyl alcohol and potassium sorbate) and Germall plus. I have sensitive skin so a bit of different preservatives work best for me rather than throwing in the highest % of a given preservative. I do have curiosity sometimes about other preservatives but I rather be safe than sorry.

    I appreciate your expert input. I will add some sodium benzoate. Whenever I add some sodium benzoate I do calculations doing the Henderson–Hasselbalch equation. I have read in this group before that in order for sodium benzoate to be effective there must be 0,1% in protonated form. Is that correct? Based on my calculations 0,25% is the needed amount at pH 4.5.

    Thanks a lot!

    Thanks for replying 🙂

    .product is a leave-in conditioner. I haven’t had any stability issues with EDTA. I want a pH around 6 , so I tried using sodium phytate as chelant and pH raiser but the emulsion broke straight away. Now with NaOH I have granules, so I will try triethanolamine to see how it goes.

    It´s possible to pass PET just with 0,5% Germall plus without chelant??

    My hair is afro 4c.

    I have checked the pH of the leave-in products that I buy an the pH is around 6.
