Introduction to Cosmetic Ingredient: Alpha-Arbutin
Alpha-Arbutin, also known as α-Arbutin, is a common whitening ingredient in cosmetics. Below is a detailed introduction to it:
Basic Information
- Chemical Name: 4-Hydroquinone-α-D-glucopyranoside, Hydroquinone-α-D-glucoside.
- CAS Number: 84380-01-8.
- Molecular Formula: C??H??O?.
- Molecular Weight: 272.2512.
- Appearance: White crystalline powder.
- Solubility: Easily soluble in water, slightly soluble in ethanol.
Efficacy and Functions
- Whitening and Fading Spots: It can inhibit the activity of tyrosinase and reduce the production of melanin, thereby alleviating hyperpigmentation. Its whitening effect is about 10 times that of β-Arbutin, which can effectively remove spots, freckles and even out skin tone.
- Antioxidation: It can scavenge free radicals in the body, prevent cells from oxidative damage, and help delay skin aging.
- Anti-Inflammatory and Antibacterial: It can reduce skin inflammatory reactions, help reduce the growth of acne, and also has antibacterial effects.
Mechanism of Action
It blocks the biosynthesis of epidermal melanin by inhibiting the enzymatic oxidation of tyrosine and dopa by tyrosinase, thereby achieving the whitening effect.
Precautions for Use
- Sun Protection: Although its photostability is better than that of β-Arbutin, strict sun protection is still necessary to prevent it from becoming ineffective due to light exposure and consolidate the whitening effect.
- Concentration Control: According to the opinion of the Scientific Committee on Consumer Safety (SCCS) of the European Union, the maximum safe concentration of α-Arbutin in face creams is 2%, and in body lotions is 0.5%.
- Avoid Incompatibility: Pay attention to avoiding compatibility with certain preservatives (such as methylparaben), so as not to produce substances that are irritating to the skin.
