Method
- Ethical approval:
- not specified
- Details on study design:
- Three solution of tartaric acid at concentration 0.16 M was partially neutralized with sodium phosphate respectly to pH 3, pH 4, pH 5 and tested to human eyes.
- Exposure assessment:
- not specified
Results and discussion
- Results:
- Dilute solutions of tartaric acid has at times been employed as eye washes with the aim of counteracting the effects of alkalies in alkali burns. Tests on human eyes of 0.16 M tartaric acid partially neutralized to pH 3 with sodium phosphate caused severe stinging but no injury. When adjusted to pH 4, it caused mild to
moderate stinging, and at pH 5 caused only slight discomfort.
