Science

Mechanism of Action

This botanical powder contains natural saponins, which function as mild surfactants, creating a gentle lather to lift away dirt and impurities from the skin. Beyond its cleansing action, it also provides anti-inflammatory and antimicrobial support, aiding in soothing irritation and protecting against common skin concerns. It contributes to skin hydration by forming a protective barrier, and its inherent exfoliating efficacy promotes a smoother skin texture.

While generally well-tolerated at typical cosmetic concentrations, studies indicate that a saponin-rich extract derived from Saponaria officinalis can become more toxic to HaCaT cells than common synthetic surfactants like SLS or SLES when its dry mass content exceeds 0.63%.

The Cosmetic Ingredient Review (CIR) has not specifically evaluated Saponaria Officinalis Leaf/Root/Stem Powder. However, a saponin-rich extract exhibited no cytotoxic effects on human keratinocytes up to 0.039% dry mass, and a skin patch test showed negligible irritation (mean score 0.28). Caution is advised as concentrations above 0.63% dry mass can lead to increased cellular toxicity. Oral ingestion in substantial amounts may cause irritation to skin, mucous membranes, and the stomach.
