@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.

[carplgrower]

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.

[carplgrower]

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

[carplgrower]

@ngarayeva001, thank you for your detailed replies. I got it:)

[carplgrower]

@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:)

[carplgrower]

Thank you @sven

[carplgrower]

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.

[carplgrower]

Sorry I have Polysorbate 80, not a Polysorbate 60.

Can I use Polysorbate 80 instead of Polysorbate 60?
