Acetic Acid 0.6% — EU research guide.

What is Acetic Acid 0.6%?

Acetic acid 0.6% is a dilute aqueous solution of acetic acid, about 6 mL of glacial acetic acid per litre, which corresponds to roughly 0.1 mol/L; calculated for that strength, the pH is about 2.9. Vendors list it as acetic acid water. It is not a peptide and has no drug mechanism of its own: it is a solvent. Unlike bacteriostatic water it contains no benzyl alcohol preservative.

What does the research show?

No efficacy claims are made: it is a solvent, not a treatment. The clearest published statement comes from a manufacturer datasheet. R&D Systems names sterile 100 mM acetic acid as the solvent for its recombinant LR3 IGF-I, supplies that product lyophilised from an acetic acid solution, and states storage limits after reconstitution of 1 month at 2 to 8 °C or 3 months at −20 °C or below under sterile conditions. That datasheet covers one product only; it does not establish which solvent suits any other peptide, and PeptideCompare gives no reconstitution instructions. The two common liquids are different products: a bacteriostatic water label gives a pH of 5.7 (4.5 to 7.0) and lists benzyl alcohol, whereas dilute acetic acid is strongly acidic by comparison.

EU legal status

This page does not name any marketing-authorised medicinal product sold as acetic acid 0.6%. A vial sold by a research vendor is not itself an authorised medicine unless it carries a marketing authorisation number; the sterility, endotoxin level, actual concentration, grade and labelling of a specific vendor vial cannot be assumed from this page, so the COA and label of each listing should be read.
