Science

Mechanism of Action

This ingredient operates primarily as a natural surfactant, leveraging its saponin content to form a gentle lather that effectively lifts and removes dirt, excess oil, and impurities from the skin. It exhibits anti-inflammatory effects by modulating inflammatory pathways, which can alleviate symptoms associated with conditions such as acne, rosacea, and eczema. Its rich antioxidant profile provides protection against free radical damage and oxidative stress. Additionally, the natural saponins facilitate mild exfoliation, promoting a smoother and brighter complexion. It also offers moisturizing, skin conditioning, and antimicrobial activities, targeting various microorganisms, including those linked to acne.

Key findings

  1. 01 An in vitro anti-acne study demonstrated that Sapindus mukorossi flower water extract at 1% and 2% concentrations significantly inhibited inflammatory cytokines. No significant cytotoxicity was observed on HaCaT cells at concentrations between 0.1% and 2%.
  2. 02 Sapindus mukorossi extract, when tested on rabbit skin at concentrations ranging from 0 to 100 mg/mL, did not induce dermal irritation or redness, confirming its safety for external application.
  3. 03 Cosmetic formulations typically incorporate this extract at 3-7% as a natural active to address skin tiredness, enhance skin tone and elasticity, and provide moisturization.

Stability

The extract demonstrates optimal stability within a pH range of 4.5 to 6.0. Its natural surfactant properties enable it to act as an emulsifier, aiding in the creation of stable oil-in-water emulsions. For optimal integration, it should be incorporated into the water phase of an emulsion. To counteract potential dryness, particularly at higher concentrations, formulations may benefit from balancing its cleansing properties with emollients and humectants.

Synergies

  • Emollients (to enhance skin hydration and mitigate potential dryness)
  • Humectants (to boost moisture retention)
  • Other anti-inflammatory agents (for enhanced soothing effects)
