  • Best emulsifiers combinaison

    Posted by Fekher on February 13, 2025 at 2:16 pm

    I have many emulsifiers and i want to make the best combinaison for getting best texture (viscosity, sensoriel feeling) and stability for o/w emulsion :

    So i have :

    Polysorbate 20 , peg 40 hydrogenated castor oil, cetearteh 3 ,steareth 2 , Steareth 20 ,ceteareth 20, peg 7 glyceryl cocoate, peg 150 Distearate , gms se, cetearteh 25

    *I tried cetearteh 20 with cetearyl alcohol as recommended combinaison found in forum but the résultat was bad low viscosity with high soaping effect

    * I tried gms se with steareth 20 i got better texture but viscosity still low

    What much viscosity do you what and have you got?

    What combinations and at what percentage have you used?

      Not really pricise value just thick cream and the level of emulsifiers Will be better lower then seven with 5% and can be more of cetearyl alcohol .

        With these emulsifiers Try 3% ceteareth 20+ 40% cetearyl alcohol or 2% ceteareth 20 + 2.5% cetearyl alcohol.

        I recommend other types of emulsifiers.

          I tried untill 4% cetearteh 20 with 6% Cetearyl alcohol and didn’t get desired viscosity plus at that level of cetearteh 20 soaping effect is huge

            Maybe there is problem with your raw materials or production method because those amount should give high enough viscosity.

            Try adding some gums

              Actually it is quite thick but soaping effect is solo bad just compairing with the same level of sabowax ae it is thin

              It is too much emulsifier. That is why it soaps. As graillotion mention, you should increase viscosity by adding polymers that increase stability too.

              Try this combination, it will have less soaping.

              Cetearyl alcohol 1.5%

              GMS 3.6%

              cetearteh 20 2.2%

              Thanks a lot for that i Will make a try May i Will increase cetearyl alcohol.

              Just i aim to make something near to Sabowax ae it needs 5% with some cetearyl alcohol to get thick and lovely texture without need of other texture agent .

              I suggest if you increased one of them, increase all others too.

              I also suggest you make a sample with good old sodium Lauryl sulfate. I bet you would love it.

    I am at a complete loss. Why are you asking your emulsifier to bring the viscosity? I couldn’t imagine a scenario I would not appreciate more. Emulsifiers generally don’t feel that nice. They have ONE JOB…. to emulsify the phases. Let them do their job. You use only the amount it takes to accomplish a stable emulsion. What if you want a thin emulsion…and your emulsifier brough viscosity?

    This is why the 165 is sooooooooooo appreciated globally….. it allows an incredible range of viscosity; you simply thicken to taste. You thicken with things that feel nice….NOT emulsifiers. 🤮

      The best emulsifier combo is…. the one that holds things together for longer than the shelf-life of the product. It is also one that gives you the freedom to create any viscosity your project calls for. I use 165 to make thin lotions….or the thickest of creams….. because it holds thing together. The viscosity…..and how that is achieved….is a completely separate topic.

        Emulsifiers can be also thickner so my question about that . If i have acess to neowax 165 or other i Will not work and ask to replace them. Unfortuently we are surfering from the absence of auto Emulsifiers for a long time now this push to do that…

      What are the things that thicken with nice feel ?
