    I have played around quite a bit with this ingredient and I do like it. I have not subjected it to PET yet as I have had no customers pick up a formulation with it in so far. But generally it doesn’t cause any instability issues in emulsions and I would always use something else with it, perhaps a natural glycol or Lexgard Natural. Although I have not challenged it, I have never had any visible (mould) growth on the surface of my samples. For me, if it is Cosmos certified then I will accept it as natural. One other point I like about it that it can be used up to pH 8 which makes it suitable for mineral based natural sunscreens and natural mascaras.

    Thanks!

    I have worked with this compound. Certainly, it cannot be considered as “natural”. Its properties are very similar to ethylhexylglycerin as well as obviously, they are completely comparable from the chemical standpoint. Comparable but… but they cannot replace each other. EHG outperforms MHG. However, MHG has nicer emollient properties and leaves velvety smooth not tacky finish on skin. MHG works as EHG in deo formulations, but its deodorizing efficacy is lower. We also compared two combinations EHG+Phenoxyethanol and MHG+Phenoxyethanol. While EHG+phenoxy works as a preservative in some formulations, MHG and phenoxy showed insufficient activity and required additional components. However, the combination of EHG+MHG+Phenethyl alc. was highly efficient against all potential microbial agents, including Aspergilus n., Pseudomonas, S.aureus and yeasts. We also found that MHG was efficient as antidandruff preparations as the only active ingredient at 2.2%.   

    oh wow, very interesting. Thanks for the information.

    That’s exactly the issue - there’s nothing about this other than Inolex promotional claims including the unjustified “natural” for what is very likely another synthetic material.  No efficacy and just as important - no safety.

    thanks. Yes I read this before, but there wasnt more information besides this on the internet, thats why I was wondering if anyone had any experience or comments using it.

    Inolex offers no data efficacy or safety - just comments that its a bacteriostsat (inhibits doesn’t kill)  and in that it doesn’t cover molds. 
    For every ingredient, you are responsible to answer with data showing its safety.   That’s not excused even  if the claim “natural” is true (and that would be interesting)

    not as sole preservative if that’s what you’re asking (in combo with Euxyl PE9010  INCI: Phenxyethanol /Ethylhexylglycerin), but I did use it in a cream and it had a bonus side effect of reducing the soaping I was seeing.
