  • Best eco preservative for lotions. Optiphen is too destabilizing.

    Posted by ProfessorHerb on February 27, 2022 at 12:50 am

    Optiphen has an incredibly nice skin feel but it destabilizes emulsions too easily. In one lotion recipe I have to wait the next day until the batch of lotion is completely cooled down and then its too solid to put into bottles. Is there another eco preservative that would work well with lotions?

    Have you considered building a better emulsion?

    Use phenoxyethanol or DMDM hydantoin with Paraben or IPBC.

    Optiphen is likely to have little effect on the skin feel of a finished Cosmetic product.

    You can use Euxyl PE 9010 instead of Optiphen. The Optiphen can cause viscosity issues because of the Caprylyl glycol in it. Ofcoarse it depends of the emulsifier system you use. Some can be affected, some can’t. If you post your formula here, we can tell you in more details  about what is happening.

    It would be also helpful if you better defined “eco preservative”. By some definitions Phenoxyethanol is not an “eco preservative”.
