  • New (to me) preservative - E-Leen P8

    Hey guys,

    E-Leen P8
    INCI: Caprylyl Glycol, Phenylpropanol, Water

    this one is new to me. Does anyone have any experiences with it? 
    Is it good, is it bad? I don’t want to fall for all the promises from supplier. :smiley: And it’s a bit pricey.

    I usually go with Liquid Germall Plus or Euxyl PE 9010. 

    Here’s what I found on re-packer’s website -

    E-Leen 8 is a new innovations for self-preserved and nature-based formulations. All ingredients are 100% natural origin, COSMOS and NATRUE approved.

    The preservative  is desinged around a pioneering bio-based Caprylyl Glycol that is produced via green chemistry from sustainably sourced coconut and palm kernel oils. The utilized raw materials are all GMO-free and 100% plant-based.

    E-Leen 8 is  efficient at low use levels and at various pH-levels. Being free of conventional preservatives, it represents an unparalleled economical option for the alternative protection of natural cosmetics.

    Usage: 0.5 - 2%
    pH: 3 to 10
    E-leen is easily incorporated into emulsions but will not dissolve into highly aqueous solutions. To use in these formulae, mix E-Leen P8 with a solubliser (such as Natural Solubiliser) before adding to your recipe.

    Cap glycl and phenylpropanol (nature based?) marketed more on hype than efficacy.  Easy unsupported claims of broad range, preservative-free resistance-proof efficacy  wide pH range economic and “natural”. - used car salesmanship.
    Unless you have the capabilities to investigate in depth - suggest you stick with your current systems.

    The Caprylyl Glycol which is a part of Optiphen, tends to destabilize the emulsions. It broke a lot of my emulsions in the past, so I don’t use it anymore.
