  • PEG 40 LIQUID OR SOLID?

    Posted by LGrey on July 7, 2021 at 7:44 pm

    Hello everyone

    Recently I ve been looking for information about hair pomades and I have looked that PEG 40 is a typical ingredient in this type of product. 
    I found that we can get PEG 40 in paste (solid) and in liquid presentation. 
    What is the difference of these two forms? Why the physical differences?

    Hope you could solve my doubt.

    @LGrey You may have misinterpreted the INCI listing. That “PEG-40” likely preceded “Hydrogenated Castor Oil”. These are components of the same nonionic surfactant, not separate ones. PEG-40 itself would be difficult to find! (PEG-32 is a standard MW). Regarding that ringing edge pomade formulation, I found PEG-25 Castor Oil (non-hydrogenated) to work even better: nice glosser and augments the alkyl ethers in micronizing.
