  • Steareth-21 Not Available, Alternative Route?

    Posted by MangoMonster on February 18, 2020 at 12:55 am

    Newcomer here. I’m formulating a wax and one of the ingredients I would like is Steareth-(21) due to it functions as a cleansing agent, a surfactant, and an emulsifier. However, it is not affordably available, and from what I’ve researched, it seems to be a mixture of polyethylene glycol ether made from stearic acid. How can I formulate this Steareth at home?

    @MangoMonster i think that it Will be more easy and lower cost when you buy it. However if you Just want to make it make some reaserachement about that.

    That’s not how it’s done. Post an entire formula with %, explain what function you are looking for and ask what can you use to replace Seteareth 21.

    What type of product are you making?  Steareth-21 is not really a cleansing surfactant. It is more of an emulsifier.

    @perry I’m making a high-hold, medium shine pomade wax. Steareth-20/21 seems to be a common ingredient in pomade waxes, that’s why I ask.  

    Petrolatum
    Lanolin
    Triethanolamine
    Cetyl Palmitate
    Cetearth-25
    Peg-40
    Oleth-5
    PVP
    Propylene Glycol
    Ethylnexyl Glycerin
    Carbomer
    Phenoxyethanol
    H20 (Aqua)
    Steareth-20/21?

    Haven’t calculated percentages yet.

    In your case @MangoMonster Cetearth-25 can do the job without Steareth-20/21.

    Following up, does anyone know where I could buy smaller amounts of Oleth-5?

    You probably won’t need oleth-5 either for a start. Ceteareth25 and peg40 hydrogenated castor oil is more than enough for this type of formulation.
