Phenoxyethanol vs. Phthalates: the difference

At Perception Skin, we believe in intentional skincare - where safety, efficacy, and integrity are always in balance. One ingredient that’s often misunderstood is phenoxyethanol, which is sometimes confused with phthalates.

Having personally experienced estrogen dominance and hormonal acne, I approach ingredient choices with great care. While phthalates and phenoxyethanol are occasionally mentioned in the same context, they are very different substances with distinct properties and uses.

Phenoxyethanol is a globally approved preservative used at low concentrations (typically under 1%) to prevent microbial growth in water-based products. It’s considered non-disruptive to the skin barrier, readily biodegradable, and does not accumulate in fatty tissues. Current research does not support claims of endocrine disruption when used within regulated limits.

Potassium sorbate, by contrast, is a nature-identical preservative, lab-created to mimic a compound found in berries. While gentle and biodegradable, it can be less pH-neutral and more reactive on sensitive skin.

At Perception Skin, we use phenoxyethanol only when absolutely necessary, in formulas that contain water or botanical extracts. Our oil-based products require no synthetic preservatives and are instead protected with natural antioxidants like Vitamin E to maintain freshness and performance.
