A single rinse may tackle vaginal odor, and a safety trial puts it to the test
NCT ID NCT07802483
First seen Sep 03, 2026 · Last updated Sep 04, 2026 · Updated 1 time
Summary
This trial tests whether a single-use instant rinse containing lactic acid or boric acid is safe for women who notice abnormal vaginal odor. Researchers will enroll about 90 non-pregnant women aged 18 and older who rate their odor at least 4 on a 10-point scale. Participants will use one of the rinses or a placebo, and then answer a questionnaire about their experience. The goal is to see if these new rinse formulas cause any safety concerns after one use.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lactic acid instant odor rinse or boric acid instant odor rinse, compared with a placebo rinse
- What this could lead to
- If the rinse proves safe, it could offer a simple, over-the-counter option for women to manage vaginal odor after a single use.
- What could go wrong
- This is an early safety study with only 90 participants, so it cannot confirm how well the rinse works. Some women may experience irritation or discomfort from the rinse ingredients.
