  • Do you have any water in your formula? If not will it be in any contact with water?
  • I make some similar products, and haven't been putting any preservatives in it, with no problems. Maybe that's wrong, but my products should not have any contact with water.
  • can you make sure that the Hemp Extract is oil base not water base?
  • Do you have any water in your formula? If not will it be in any contact with water?
    No water in the formula or are we planning on adding water.
  • can you make sure that the Hemp Extract is oil base not water base?
    Yes.  The hemp extract is oil based.
  • I have read that the citrus essential oils would work as a preservative.  Is there any truth to this claim?

    @Bios - it wouldn't be effective for most formulations. Depending on the type there are also safety concerns when applied to skin.

    Linatural CO-NLP-1

    Certified organic orange / lemon grass / sunflower oils / natural alcohol

    I've used this in conjunction with Lexgard Natural in a clay-based product and it passed PCT.

    Since you have an anhydrous formula, you should not have any issues.

    Agree with Perry ... an EO-based preservative would most likely not be effective in most formulas if used solo.

    Mark, isn't d-Limonene the factor in that NLP-1 concoction? 
  • MarkBroussardMarkBroussard Member, Professional Chemist
    I suspect so ... that and the alcohol.  I've never looked at a compositional analysis of it, but you are probably correct.

  • Any opinions on Japanese Honeysuckle Extract as a possible preservative?  
  • MarkBroussardMarkBroussard Member, Professional Chemist
    I've use it with both success and failure ... so you will be best off coupling it with hurdle technology and possibly a complimentary preservative

    @Bios - it works great when it is spiked with parabens and formaldehyde donors.  https://personalcaretruth.com/2010/07/honeysuckle-plant-extract/

  • MarkBroussardMarkBroussard Member, Professional Chemist
    The "active" in the Honeysuckle is actually a paraben precursor.  Though not technically a paraben, the molecular structure is very close to parabens.
