Valuable CAS 84787-69-9 / ASTRINGENT, FRAGRANCE, TONIC

Rubus Fruticosus Fruit Extract, sourced from blackberries, is a rich botanical extract offering multi-faceted benefits. It acts as a powerful antioxidant to shield skin from environmental stressors and supports structural integrity by enhancing collagen and elastin synthesis, promoting a revitalized and firmer appearance.

Summary

Antioxidant Anti-inflammatory Hydrator Exfoliant Collagen Booster Elastin Booster Barrier Strengthening Oil Balancing Astringent Tonic

Science

Mechanism of Action

This extract functions through its rich profile of antioxidants, including polyphenols, flavonoids, anthocyanins, and vitamins C and E, which actively neutralize free radicals generated by UV exposure and environmental pollution. It contributes to reducing inflammatory responses by decreasing UVB-induced IL-6 production in keratinocytes. Furthermore, it stimulates collagen synthesis to diminish dark spots and boost radiance, while also upregulating elastin gene transcription, stimulating tropoelastin production, and inhibiting elastase enzymes to improve skin elasticity. Its fruit acids provide gentle exfoliation, promoting cellular renewal and decongesting pores. Additionally, it delivers intense hydration, helps balance oil production, and its tannins fortify the skin barrier, reducing moisture loss for enhanced resilience.

Key findings

  1. 01 In-vitro studies demonstrate a concentration-dependent decrease in UVB-induced IL-6 production in keratinocytes, observed with pre-treatment at 25 mg/L and post-treatment at 10 mg/L and 25 mg/L.
  2. 02 Research indicates the extract upregulates elastin gene transcription, stimulates tropoelastin production, and inhibits both leukocyte- and fibroblast-derived elastase activity, suggesting enhanced collagen and elastin synthesis.

Dusting Analysis

Not commonly dusted

While specific optimal cosmetic percentages are not readily available, in-vitro studies demonstrate anti-inflammatory effects at concentrations as low as 10-25 mg/L. Its broad spectrum of proposed benefits, including antioxidant protection, collagen and elastin support, and hydration, suggests it functions as a genuine multi-functional ingredient beyond merely a 'dusting' claim.

Stability

The extract is water-soluble and often extracted using water or glycerin. It shows stability and extraction efficiency in acidic conditions, particularly pH 2.5, and specifically for anthocyanin analysis at pH 1 and pH 4.5. Its high anthocyanin content imparts a deep purple or dark reddish liquid appearance, which may influence the final product's color.
