Product Introduction:

Phloretin, alias trihydroxyphenol acetone 2,4,6-trihydroxy-3-(4-hydroxyphenyl)propiophenone. It is a new type of natural skin whitening agent recently researched , mainly distributed in the peel and root bark of juicy fruits such as apples and pears.

It can be used in facial masks, skin creams, lotions and essences. It is a pearl white crystalline powder, soluble in ethanol and acetone, but almost insoluble in water.

For human skin, it has strong antioxidant and photoprotective effects (it can eliminate the increase of free radicals in the skin caused by ultraviolet rays and damage to cells and DNA), and it can also inhibit matrix metalloproteinases (MMP-1). ) And the activity of elastase, these enzymes can degrade the connective tissue of the skin and play an important role in the skin photoaging process.

The properties of phloretin:

  • Melting point: ~260°C
  • Boiling point: 337.26°C(roughestimate)
  • Density: 1.1827(roughestimate)
  • Refractive index: 1.573-1.575
  • Storage conditions: 2-8°C
  • Acidity coefficient (pKa): 7.16±0.40(Predicted)
  • Form: Powder

Biological activity of phloretin:

  1. Antioxidant and antioxidant effect
    • The peroxidative activity of flavonoids was identified in the 1960s, and many flavonoid polyhydroxyl structures are believed to have antioxidant properties because they can chelate with metal ions and have significant antioxidant properties.
    • It has strong antioxidant properties, and the antioxidant concentration of oil is between 10-30PPm, which can remove free radicals from the skin. Disease, external use can prevent sugar components from entering the epidermal cells, suppressing the excessive secretion of skin glands and treating secretory acne.
    • Studies have shown that phloretin inhibits the activity of melanocytes and has a whitening effect on various skin spots. It has a good inhibitory effect on tyrosinase and is a very safe and effective freckle whitening agent. Phloretin has a very good moisturizing effect and can be absorbed 4 to 5 times its own weight. As a very safe and effective transdermal penetration enhancer, phloretin may be more effective by promoting the absorption and utilization of other functional factors in the formulation. Because phloretin has a good LOX inhibitory effect, phloretin is a good anti-hair loss agent.
  2. Anti-inflammatory and immunosuppressive effect
    • Studies have shown that the development of inflammation is associated with NO. NO is catalyzed and synthesized by NO synthetase, and excess NO is catalyzed by inducible NO synthetase under pathological conditions. Under the action of phloretin, the release of NO from macrophages was greatly reduced under the stimulation of lipopolysaccharide and IFN-γ inhibition, and the phagocytosis rate of megalithic cells was also significantly reduced under the action of phloretin. Therefore, phloretin has potential anti-inflammatory effects.
    • In terms of immunosuppression, phloretin is known as a competitive inhibitor of the sodium D-glucose cotransporter. Because it can increase the fluidity of the intracellular lipid bilayer, it can increase the type and activity of drugs delivered through the skin.
  3. Anti-cancer and anti-cancer effect
    • γδ T cells are innate immune T cells that are widely present in mucosal and epithelial tissues of the digestive and respiratory systems. In addition to some functional properties similar to αβT cells, the antitumor effect also recognizes antigens without MHC. , It directly recognizes non-peptide antigens, protein and peptide antigens, has an antigen extraction function, and can play a role in immune regulation through cell contact and cytokine secretion.
  4. It also has anti-diabetic and anti-Parkinson’s disease effects.

Related research:

  • With the increase in the market share of plant functional cosmetics, phloretin has successfully attracted the attention of researchers in the beauty industry with its multi-functional beauty effects. Studies have found that phloretin has various pharmacological effects such as anti-oxidation, anti-tumor, anti-inflammatory, immunosuppressive, and promoting bone formation. In addition, it also has the effects of whitening and removing acne.
  • It can be directly absorbed by the human body, but in plants, there is very little naturally occurring phloretin, and most of the phloretin exists in the form of its glycoside derivative-phloridin. Phloridin absorbed by the human body is in the gastric mucosa. After the glycosidic group is removed to produce phloretin, it can enter the circulatory system and exert its effect.
