What is Gluconolactone?

Gluconolactone is a naturally occurring compound derived from gluconic acid, often found in honey and fruit juices. It is produced commercially by the oxidation of glucose and is frequently utilized in the cosmetics and food industries.

Gluconolactone functions as a gentle exfoliant in skincare products like sunscreen and hand sanitizers. It is part of the polyhydroxy acid (PHA) family and is known for its moisturizing properties. Current evidence suggests it is generally well-tolerated by the skin and does not cause significant irritation.

When you see gluconolactone on a label, it is likely used to enhance product stability or to provide mild exfoliation and hydration. It is considered a versatile and safer alternative to more aggressive acids.
