What Is It?

pH measures the acidity or alkalinity of a solution on a scale of 0 (most acidic) to 14 (most alkaline), with 7 being neutral. For ozonated glycerin, pH indicates the degree of ozonation and the product’s compatibility with the skin’s natural acid mantle.

How We Measure It

We use a Hanna Instruments calibrated digital pH meter with ±0.01 resolution. The meter is calibrated against NIST-traceable buffer solutions before each measurement session. pH readings are taken from each vat after the ozonation cycle is complete.

Why It Matters

Properly ozonated glycerin should be mildly acidic, typically in the 3.5–5.0 range. This slight acidity is beneficial — it closely matches the skin’s natural acid mantle (pH 4.5–5.5), meaning Glyzine works harmoniously with your body’s natural barrier. A more neutral pH (5.5+) in ozonated products often indicates insufficient ozonation.

Our Acceptance Criteria

SimplyO3 Glyzine pH must fall within 3.0 – 6.0. Our batches typically measure around 4.5, confirming thorough ozone saturation while maintaining excellent skin compatibility.
