Ingredient Logic
The Ingredient Glossary
One entry per ingredient, written once and surfaced everywhere — on flip cards, on product ladders, and here. If an ingredient is in an ingredientlogic formula, it has a page.
Phenoxyethanol
A widely used cosmetic preservative, present in our formulas at 0.01–1%.
It keeps a water-containing formula safe over its shelf life. In the mascara this matters most: bacterial growth in a product used near the eyes is a real risk, and we would rather name a preservative than accept that risk.
Full entry →Caprylyl Glycol
A skin-conditioning glycol that also boosts the performance of other preservatives.
It lets the phenoxyethanol work at the low end of its range. Less preservative for the same stability is a trade worth naming.
Full entry →Potassium Sorbate
A mild food-grade preservative, the potassium salt of sorbic acid.
It covers mold and yeast, which the phenoxyethanol alone does not fully address in a water-based eye formula.
