EUCALYPTUS LOXOPHLEBA LEAF OIL.

Valuable / FRAGRANCE

EUCALYPTUS LOXOPHLEBA LEAF OIL is an essential oil rich in the active compound 1,8-cineole, valued for its significant antimicrobial, anti-inflammatory, and sebum-regulating properties. It offers a multifaceted approach to improving skin health by targeting various concerns from bacterial proliferation to inflammation and excess oiliness.

Summary

Anti-inflammatory Antimicrobial Antibacterial Antioxidant Sebum-regulating Potential depigmenting agent

Science

Mechanism of Action

This ingredient exerts its effects primarily through 1,8-cineole (eucalyptol), which functions as an anti-inflammatory agent by modulating the body's response to infection, reducing redness and soothing sensations of heat through the inhibition of inflammatory mediators such as tumor necrosis factor (TNF), interleukin-1, leukotrienes, and thromboxane. It also possesses antibacterial and antimicrobial properties, with 1,8-cineole disrupting bacterial cell walls to increase permeability, leading to the release of essential bacterial proteins and nucleic acids. Furthermore, it aids in rebalancing oily skin by regulating sebum production and potentially reducing the size of sebaceous glands. Its phenolic compounds also contribute to antioxidant activity and may offer depigmenting effects by inhibiting tyrosinase and melanin production.

Safety Profile

CIR Status
Safe with restrictions
Max tested
0.4%
Sensitization risk Moderate

The CIR Expert Panel concluded that Eucalyptus globulus-derived ingredients (which are considered inclusive of Eucalyptus globulus and other species of Eucalyptus for Eucalyptus Globulus Leaf Oil) are safe in cosmetics. However, this is contingent on formulation to be non-sensitizing and adherence to specific concentration limits. For leave-on dermal applications, the highest safe concentration is 0.4%. Proper dilution and individual skin testing are highly recommended due to the potential for irritation and sensitization in some individuals. It should not be applied to the face, especially the nose, of infants or young children. No specific SCCS or FDA status was found for EUCALYPTUS LOXOPHLEBA LEAF OIL.

Verdict

Valuable

EUCALYPTUS LOXOPHLEBA LEAF OIL is a valuable ingredient for precision skincare, offering robust antimicrobial, anti-inflammatory, and sebum-regulating benefits, but requires careful formulation within a 0.4% maximum for leave-on products to ensure safety and minimize irritation.
