MICROCITRUS AUSTRALASICA FRUIT EXTRACT.

Valuable

Derived from the Australian Finger Lime, Microcitrus Australasica Fruit Extract is a multi-functional ingredient that gently exfoliates, protects, and hydrates the skin. It promotes cell renewal, combats environmental stressors, and improves overall skin texture for a brighter, smoother complexion.

Science

Mechanism of Action

MICROCITRUS AUSTRALASICA FRUIT EXTRACT acts as a gentle exfoliant primarily due to its natural alpha hydroxy acids (AHAs), including citric and malic acids, which stimulate cell regeneration for smoother and more even skin tone. This exfoliating action may also be linked to the stimulation of TRPV3 synthesis. The extract offers robust antioxidant protection through a rich profile of flavonoids, terpenes, linalool, vitamin C, folic acid, and polyphenols, effectively neutralizing free radicals and guarding against environmental damage and premature aging. It also contributes to skin hydration and conditioning through its inherent vitamins, minerals, and natural sugars that attract and retain moisture. Furthermore, this extract may exhibit anti-inflammatory properties, aid in skin brightening by reducing pigmentation, and support the repair of the skin barrier function alongside collagen production.

Stability

No specific optimal pH range for stability was identified. For optimal integration, it is recommended to add the extract during the cool-down phase of formulation, when the temperature is below 40°C. General usage guidelines suggest incorporating up to 5% of the extract.

Conflicts

  • Volatile fragrance components may trigger skin irritation when combined with this extract.
  • Individuals with very sensitive skin may experience slight irritation, particularly when this extract is formulated with other chemical exfoliants.
  • Formulators must carefully monitor the cumulative levels of similar constituents across multiple botanical ingredients to prevent hazardous concentrations.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that MICROCITRUS AUSTRALASICA FRUIT EXTRACT is safe for cosmetic use, provided formulations are non-sensitizing and non-irritating. A crucial restriction for leave-on products dictates that the concentration of 5-methoxypsoralen (5-MOP) must not exceed 0.0015% (15 ppm). The fruit itself is generally recognized as safe (GRAS) for food by the FDA. The SCCS status has not been reviewed.
