Portulaca Oleracea Extract

Portulaca oleracea (purslane) extract is primarily a soothing/antioxidant botanical used at low levels (typically <1–3%) in leave-on products, and it is generally well-tolerated with a low rate of irritation in patch-test and consumer-use contexts. However, as a complex plant extract it can still trigger occasional irritant or allergic reactions in highly reactive/eczema-prone individuals depending on extraction solvents and co-occurring plant constituents, so it is not scored as inert. Safety Notes: In mass-market and prestige leave-on products (serums, creams, toners), Portulaca Oleracea Extract is commonly used as a soothing/antioxidant botanical at very low levels (often ~0.01–0.1%) as part of multi-extract blends where it functions primarily for marketing and minor skin-calming support. Higher-strength consumer products—typically “cica/soothing” ampoules, concentrated gel serums, and sensitive-skin formulas—use it at ~1–5% when the supplier extract is a standard liquid/glycolic extract; above ~5% is uncommon in OTC products due to formula stability, odor/color impact, and diminishing returns (noting that marketed “10%” claims are often for a complex or ferment rather than pure Portulaca extract). Rinse-off products (cleansers/masks) tend to sit toward the low end because of short contact time, while leave-on products occupy most of the upper range.
