    @JonahRay;
    Yes it is. Sorry for my English.

    @Belassi;
    I try with many thinks such as stick blender, milk frother, stick blender with whisk attachment… with low speed to very high speed. Results are same.

    @ozgirl;
    Because in my country I can only access them as a raw material. I tried to create exactly with Ritamulse ratios (%60 Glyceryl stearate, %25 Cetearyl alcohol and %15 SSL) and added to oil phase. Result is not so different.

    @Microformulation;

    I used stick blender, milk frother, blender with whisk attachment even driller with blender attachment. Low speed, medium speed, high speed…

    The best result I got with milk frother.

    I heat with bainmarie, mix to phase at 78-80 celcius degree, mix them at that temperature for 1-3 minutes and put the mixture in cold water bath. I continuously mix it, until cool to 28-30 celcius degree.

    Yes I check ph. My final pH is 5.7-5.8

    Weight of batch is 200 g.

    If I re-heat the mixture, second result is thicker than first one and third one has a creamy viscosity.

    I also think that every heating mixture lost of some water as due to evoparation. But I think it is not the problem because I lost only 1-1.2 g of water on the 200 g final product.

    Thank you for your helps.

    @Microformulation, dimethicone cover the lice body and plug their respiratory holes. So lices are drowning.

    But if I remember correctly it can only use as hair lotion, not as shampoo. Because it must be sit on scalp 5-8 hours.

    Hello;
    In my country there is a anti-lice soap and shampoo which contain “camphor”. It is traditional treatment and it is very effective.

    It must be otc ingredients all over the world.

    @em88 thank you for your reply. Yes you’re right first formula has more w/o emulsifier glyceryl stearate.

    In fact I copied emulsifying wax with name Ritamulse/Ecomulse/Naturemulse/Emulsimulse.
    It’s INCI:
    60% Glyceryl stearate
    25% Cetearyl alcohol
    15% Sodium stearoyl lactylate

    And this brands only for o/w emulsions. I don’t understand why they use that amount of Glyceryl stearate for o/w emulsifying wax?

    Thank you.

    @ngarayeva001 unfortunately I don’t have any access to PEG-100 stearate.
    @MarkBroussard thank you for your comment. What is the sign of a soaping? Whitening effect on the skin?

    @Belassi I don’t have any access to silicones too.

    In my country no one interest with prepare a cosmetics at home. Because of this cosmetic ingredients available for only professional use in a big quantity.

    Anyway I noticed that 5% Sodium stearoyl lactylate drop ph too much. I prepare 5% suspension of it with water and checked the ph level. The pH meter says it is 2.5. I think this happened due to lactic acid/lactylate.

    And according to Ritamulse formulating guidelines it says “Ritamulse should be used in products with an intended final pH of 5 - 7.5.”

    Then I prepare experimental formula with adding KOH for buffer a ph drops due to SSL.

    Experimental Formula:
    INCI:
    Oil Phase:
    8% Sweet Almond oil
    2% Grapeseed oil
    2% Shea Butter
    2% Coconut butter
    3% Glyceryl stearate
    2% Cetearyl alcohol

    Water Phase:
    3% Glycerine
    5% Sodium stearoyl lactylate
    0.3% Potassium hydroxide
    72.7% Water

    Result: Excellent. It emulsified within few minutes with nice cream viscosity. And final pH is 5.65.

    My questions:

    1- Is it normal to 5% sodium stearoyl lactylate drops pH to 2.5?

    2- Is it safe to use KOH in my formula? Is there any more suitable pH buffer for cosmetics?

    Thank you.

    Thank you for your reply @Belassi;
    My total oil content is 14%.
    How much SSL and GS I need to use? Btw I will add xanthan gum too. I already have it. Do you think that 0.3% is enough?

    Thank you again.

    thank you for your replies. I don’t think to use it. I only ask for learning:)

    @ngarayeva001 thank you for your wonderful reply :)

    First formulation (high viscous) is perfect for me. Tomorrow I will prepare and keep you informed about result.

    Just for learning, I want to ask something :)

    1-) Why we use both glyceryl monostearate and Polysorbate 80 together? Why we just calculate required HLB and not only use Polysorbate 80?

    2-) Why we use EDTA?

    3-) If we want to make too watery emulsion, is it possible to prepare emulsion without using cetyl and cetearyl alcohols?

    Sorry for lots of questions and thank you again for formula:)

    Thank you for your reply.
    So I can’t use Polysorbate 80 instead of Polysorbate 60.
    I am trying to prepare 10% castor oil/water emulsion.

    I can find;

    Cetyl alcohol
    Cetearyl alcohol 68/50
    Glyceryl monostearate
    Polysorbate 80
    Sodium Stearoyl Lactylate

    Can I prepare my castor oil/water emulsion with that chemicals.

    Thank you.

    Sorry I have Polysorbate 80, not a Polysorbate 60.

    Can I use Polysorbate 80 instead of Polysorbate 60?
