Product description

Stabilised ethyl ascorbic acid at pH 4.5 — brightening without the yellowing of L-ascorbic acid.

L-ascorbic acid at 15% is a marketing number that fails in warm markets: it oxidises in weeks and turns the serum orange. Ethyl ascorbic acid holds its colour and still delivers a measurable tone improvement.

We supply the serum in an opaque airless bottle to remove the last source of oxygen, and include a stability file covering 12 weeks at 40 °C.

Why brands choose this format

  • Ethyl ascorbic acid, colour-stable for 24 months.
  • pH 4.5, tested for irritation on 30 volunteers.
  • Opaque airless pack removes headspace oxygen.

How it is made

  1. 01 Phase — Water phase prepared with chelator and humectants.
  2. 02 Cool — Cooled to 30 °C before the vitamin C addition.
  3. 03 Fill — Airless filling under nitrogen blanket.
  4. 04 QC — pH, colour (L*a*b*) and micro before release.
