Gluconolactone or Phenoxethanol?
I’m considering Gluconolactone and Phenoxethanol as options for preserving my colour cosmetics, eyeshadow in particular. Why would I choose one over the other? Are one of these a better option for being used in powder cosmetics?
Thank you! -

If you want an ecolabel like ecocert - Glucolactone is to prefer. - or actually phenoxyethanol is not even allowed with ecocert.

Gluconolactone, in and of itself, is not a preservative and it is a crystalline solid.
Are these pressed powder formulations and are you using silicones or some other liquids in your formulation? If so, a Phenoxyethanol blend such as Optiphen would work, or you might be better off using Benzyl Alcohol (and) Dehydroacetic Acid. -
Good point MarkBroussard - I suppose he/she meant Gluconolactone/sodium benzoate.mixture

I wonder if finely ground propolis could be used as a preserver… it’s anhydrous. (just a suggestion for those wanting ‘natural’ substances)

I am not necessarily looking to provide “natural” products. However having that as an option is something consumers are looking for.
Benzyl Alcohol has peaked my interest and I am curious is there a benefit of using that opposed to Phenoxyethanol? Eco-friendly aside.MarkBroussard, to answer your question I am using silicones in my formulas. -
The benefit from using Benzyl Alcohol instead of Phenoxyethanol is a consumer perception issue. Benzyl Alcohol is ECOCert approved, whereas Phenoxyethanol is under duress from the Naturals community as a synthetic. Both work well as preservatives.
Since you’re using Silicones, you might want to consider Benzyl Alcohol (and) Caprylyl Glycol … Check out Sharon-Labs or Dr. Straetman’s for preservatives with these ingredients. -
Thank you Mark, you’ve been a great help!
