Petzl Power Liquid review

As an Amazon Associate I earn from qualifying purchases.

This is not a hands-on test. Pros and cons below come from the Amazon listing title checked on November 14, 2026, and from the maker pages linked in the text. If a detail is missing, it is not listed.

The Petzl Power Liquid page calls it non-airborne liquid chalk, volume 200 ml, made in France. Its materials line is "Magnesium hydroxide carbonate, isopropyl alcohol." The page says it dries quickly and limits hand perspiration within a few seconds of application. That timing is Petzl's sentence.

Petzl's instructions PDF lists a longer ingredient line: isopropyl alcohol, magnesium carbonate hydroxide, colophonium, hydroxypropyl cellulose, and styrax benzoin resin. Colophonium is rosin. The PDF also says the product is flammable, not to use it if allergic, and to spread a thin layer and let it dry a few seconds.

Pros

• Volume is stated twice: 200 ml on the product page and on the November 14 Amazon title.
• The product page names the mineral and isopropyl alcohol.
• The maker publishes an instructions sheet with a fuller ingredient list than the product-page materials line.
• The Amazon title matches the maker's "non-airborne" wording.

Cons

• The instructions list colophonium. This is not a rosin-free chalk, on Petzl's own sheet.
• The product page materials line omits colophonium and styrax benzoin. The two Petzl documents do not match.
• Isopropyl alcohol is named, so this is not the alcohol-free formula.
• "A few seconds" is Petzl's dry-time claim.
