its a good lipid layer enhancer with surfactants and adds mildness to wash off products. Have noticed it increasing viscocity in sulfate free systems not worked with sulfates. it is itself very viscous as a product.

Thanks Pharma

Let me try getting the materials you mentioned and also once with polysorbate 80.

I really appreciate your technical help.

Will keep you updated.

Cctg stands for caprylic triglycerides.

Thanks cafe33 for the opinion. I have been having that doubt about using lae7 but it is suggested by the supplier hence tried it. May be that’s the reason for the skin irritation.

Thanks Pharma for the opinion. I shall try out sorbitan monolaurate and cctg and liquid paraffin.
Any guidance on how much % we may need of the sorbitan monolaurate? I don’t mind trying but really have limited sample to try out.

Please let me know your suggestions about the following:

Next step:
50% glycerine in water 3%
Sorbitan monolaurate 7% ( maybe? I really have no clue here neither did I get any typical dosage reference )
Cctg 30% 
LLP: 60%

Let me know if there is any suggestion you can provide for me to formulate this product.

Thanks!

Pharma said:

Too much oil in water emulsifiers especially for a glycerol in oil formulation.

You could try a pure d-phase (sucrose stearate and laurate are your friends) or a HIPE.

High polyol content in your water phase (or pure glycerol instead of water) will shift the apparent hydrophilicity/lipophilicity balance or difference meaning you can’t use HLB and you’re likely lacking the necessary values for HLD. This may be the reason why your surfactants work against all odds.

Replacing paraffin with a short polar and/or branched-chain oil might also help to reduce the amount of required surfactant and further lowers apparent HLB (increases chances for plyol/o over o/polyol emulsion).

Addl Refernce to Q2: for 200 litre working capacity

Thanks Paprik for the suggestion 🙂 will suggest the same to the client

Thankyou, I will definitely try these. I have tried a few more combinations using different types of emollients which seemed to be working fine in removing the greasiness of argan oil. Out of all combinations the one that worked best was :

30% C13-15 Alkane

10% Octyldodecanol

10% Isopropyl Myristate

I am not sure if we can use combinations like these safely on face. If there is any data regarding safety issues, it’d be of great help.

Thankyou so much!
