PELARGONIUM ROSEUM STEM EXTRACT.

Valuable CAS 90082-55-6 / PERFUMING

Pelargonium Roseum Stem Extract, often known as rose geranium extract, is a multifaceted botanical ingredient derived from the stems of the Pelargonium roseum plant. This extract is rich in bioactive compounds such as flavonoids and terpenes, offering comprehensive benefits including hydration, antioxidant protection, and skin balancing. It is particularly valued for its ability to soothe irritation, provide antimicrobial defense, and promote overall skin health and elasticity.

Summary

Antimicrobial/antibacterial Antioxidant Perfuming Astringent Skin-balancing (sebum regulation) Soothing/anti-inflammatory Hydrating Toning

Science

Mechanism of Action

This extract exerts its effects through several key pathways: it leverages bioactive flavonoids and terpenes to deliver antioxidant benefits and support skin elasticity. It actively modulates inflammation, calming redness and irritation while promoting cellular regeneration and reinforcing the skin's natural barrier function. Furthermore, the extract helps regulate sebaceous gland activity to harmonize sebum levels, acts as an astringent to reduce the appearance of pores, and possesses broad-spectrum antimicrobial and antifungal properties. It also demonstrates tyrosinase inhibitory activity, contributing to potential skin brightening.

Conflicts

  • Not recommended for individuals with a documented hypersensitivity to ethanolic extracts of Pelargonium species or other members of the Geraniaceae family.
  • Potential for allergic reactions, including skin redness or itching, exists in individuals particularly sensitive to essential oils; patch testing is strongly advised before comprehensive use.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

Pelargonium graveolens extract, often considered synonymous in cosmetic applications, is generally regarded as safe. However, due to its essential oil components, there is a noted potential for dermal reactions such as irritation or sensitization in susceptible individuals, particularly those with essential oil sensitivities. While the FDA has approved Pelargonium oil for food flavoring at concentrations below 0.001% in finished products, this specific limit is not directly applicable to cosmetic topical formulations of the extract.
