    Hi 

    Can anyone recommend a supplier of propylene carbonate who sells in small batches?

    I want to add this ingredient to my matte liquid lipstick formula to see if to resolves some of the issues I am having. My formula uses dist. hectorite.

    Also, are there any alternatives to this ingredient?

    Best wishes,

    Daria

    Wow.

    You really need to understand the chemistry of your ingredients before you go around throwing chemicals into a formula just to see what happens.

    For example, what is “dist. hectorite”?

    Or even, why is a very polar ingredient like propylene carbonate, which is completely incompatible with lipstick ingredients, being added to lipsticks, and how is it being kept stable?

    Your best bet is to just use one of the Bentone Gels from Elementis Specialties which are dispersions of hectorite and propylene carbonate in a variety of solvents:  For instance, Cyclopentsiloxane, Stearalkonium Rectorate & Propylene Carbonate is one of their products.

    I believe the enquirer is working from an INCI LOI where stearalkonium hectorite and propylene carbonate appear as separate components rather than being a preformulated Bentone Gel.

    Dariawes, what issues are you having with your formula? The stearalkonium hectorite/propylene carbonate combination (+ most likely another oil) act as pigment suspending agents.

    @dariawes:

    Why don’t you list your formula and then it will be much easier to give you advice to directly address your issue.
