Astringent Purifying Soothing Antioxidant Refreshing Antibacterial Sebum-regulating Skin Barrier Support Fragrance Perfuming

Science

Mechanism of Action

Mentha Piperita Water primarily functions through its slightly acidic pH, which provides an astringent effect to visibly tighten pores and purify the skin. Menthol, a prominent constituent, imparts a characteristic refreshing and soothing sensation, while also contributing antioxidant properties to combat free radical damage and strengthen the skin's natural protective barrier. It promotes improved microcirculation and oxygenation to skin cells, supporting a healthier complexion. Additionally, its inherent antibacterial qualities assist in regulating sebum production and minimizing pore congestion, making it particularly beneficial for problematic or oily skin. Menthol may also enhance the dermal penetration of co-formulated active ingredients.

Conflicts

  • The menthol content in Mentha Piperita Water can enhance the dermal absorption of other ingredients, requiring formulators to re-evaluate the safety assessment of co-formulated actives if their safety relies on minimal skin penetration.
  • High concentrations of Mentha Piperita Water, or its use on individuals with sensitive skin, may lead to irritation due to its menthol content.

Safety

Safety Profile

CIR Status
Insufficient data
Pregnancy
Caution
Sensitization risk Moderate

The CIR Expert Panel found 'insufficient data' to determine the safety of Mentha Piperita Flower/Leaf/Stem Water under intended conditions of cosmetic use, despite related ingredients like Peppermint Oil, Extract, and Leaf generally being considered safe when formulated to be non-sensitizing and with pulegone concentration not exceeding 1%. The FDA lists peppermint as Generally Recognized As Safe (GRAS) for food consumption. However, due to its menthol content, this ingredient can cause irritation in sensitive individuals or at high concentrations. Some peppermint hydrosols may contain significant amounts of terpenic ketones (menthone) and are advised to be avoided by pregnant/breastfeeding women and children under 3 years old.

Verdict

Questionable

While Mentha Piperita Water offers various beneficial properties for skin health, its CIR status of 'insufficient data' and specific contraindications for sensitive individuals, pregnant/breastfeeding women, and young children due to menthol and potential ketone content, necessitate careful formulation and usage consideration.
