CITRUS UNSHIU FRUIT WATER.

Optional CAS 98106-71-9 / HAIR CONDITIONING, SKIN CONDITIONING

Derived from the Satsuma mandarin, Citrus Unshiu Fruit Water is recognized for its multifaceted benefits, including anti-inflammatory, antioxidant, and moisturizing properties. It aids in promoting skin health and maintaining a balanced complexion, while requiring careful formulation due to potential phototoxicity concerns.

Summary

Skin Conditioning Anti-inflammatory Antioxidant Moisturizing Skin Brightening Anti-aging Photoprotective Anti-allergic

Science

Mechanism of Action

This ingredient operates by mitigating inflammatory responses through the inhibition of nitric oxide, a key inflammatory substance. It supports skin hydration and anti-aging by stimulating hyaluronic acid formation and improving moisturization. Rich in antioxidants such as flavonoids, carotenoids, and coumarins, it actively protects the skin from free radicals and oxidative stress. Furthermore, it contributes to skin brightening by inhibiting tyrosinase, an enzyme involved in melanin production, and promotes skin regeneration for refined texture.

Stability

No specific optimal pH range for the stability of Citrus Unshiu Fruit Water has been identified. For formulations containing citrus essential oil components, it is recommended to maintain low peroxide levels, ideally below 20 millimoles peroxides per liter, through the inclusion of antioxidants to prevent degradation and potential irritation.

Conflicts

  • Leave-on products must not exceed 0.0015% (15 ppm) of 5-methoxypsoralen (5-MOP) due to phototoxicity concerns.
  • Care should be taken when co-formulating with other ingredients that may cumulatively increase skin sensitization or irritation.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The CIR Expert Panel has deemed citrus fruit-derived ingredients, including Citrus Unshiu Fruit Water, safe for use in cosmetic products (both rinse-off and leave-on) provided they are formulated to be non-sensitizing and non-irritating. A critical restriction for leave-on products is the limitation of 5-methoxypsoralen (5-MOP) content to no more than 0.0015% (15 ppm) to mitigate phototoxicity risks. The SCCS also notes citrus constituents as potential contact allergens, with EU regulations stipulating furocoumarin content below 1 mg/kg in sun-protection and bronzing products.

Our Assessment

Verdict

Optional

Citrus Unshiu Fruit Water demonstrates potential for soothing, hydrating, and brightening the skin through its anti-inflammatory and antioxidant activities, yet its direct clinical efficacy as fruit water at specific cosmetic concentrations is less defined than that of its extracts, requiring precise formulation to avoid phototoxic reactions from furocoumarins.
