Hydroxycinnamic Acid High-purity Super Brightening Antioxidant Stabilizing Raw Material (CAS 7400-08-0)
Hydroxycinnamic Acid is a high-purity natural phenolic active monomer refined from plant phenylalanine metabolites via low-temperature crystallization, high-precision purification and freeze-drying technology.
As a new generation of high-efficiency brightening and stabilizing ingredient in the cosmetic industry, it has super tyrosinase inhibitory ability, which is significantly superior to traditional brightening ingredients such as kojic acid and arbutin, and has dual core advantages of efficient brightening and antioxidant stabilization.
Different from ordinary brightening raw materials that are irritable, easy to oxidize and poor in stability, and conventional antioxidants with single efficacy, our cosmetic-grade 98% high-purity hydroxycinnamic acid features pure natural plant-derived phenolic structure, ultra-mild and non-irritating, high activity and excellent formula compatibility.
It has multi-dimensional skincare advantages: firstly, it competitively binds to tyrosinase active sites, efficiently blocks melanin synthesis pathway, inhibits melanin proliferation at the source, and its brightening efficacy is far better than traditional brightening ingredients, effectively improving dullness, yellowish and uneven skin tone; secondly, it donates hydrogen atoms to neutralize skin reactive oxygen species caused by UV radiation and environmental pollution, resists lipid oxidation and cell DNA damage, delays skin photoaging and chronological aging; thirdly, it has mild anti-inflammatory activity, relieves skin redness and oxidative sensitivity caused by external stimulation, stabilizes fragile skin state; fourthly, it can effectively protect unstable active ingredients such as vitamin C from oxidative failure, improve the overall stability of compound formulas, and extend the shelf life of skincare products.
In addition, hydroxycinnamic acid can be perfectly compounded with vitamin C, ferulic acid, quercetin, niacinamide and other brightening and antioxidant ingredients to build a multi-effect synergistic brightening and anti-aging system, which greatly amplifies the comprehensive efficacy of skin translucent brightening, anti-oxidation and anti-photoaging.
The product has stable physical and chemical properties, no discoloration or activity loss in conventional cosmetic processing, non-sensitizing, non-toxic and harmless, free of heavy metal residues, passed multiple skin safety tests, suitable for all skin types including sensitive skin, and is a high-quality multi-functional core raw material for high-efficiency brightening and anti-aging skincare products.
Key Benefits
• Superior Brightening Efficacy, Stronger Than Traditional Ingredients: High-purity phenolic monomer, super tyrosinase inhibitory activity, the brightening effect is significantly better than kojic acid and arbutin. It precisely suppresses melanin production and solves stubborn dullness and yellowish skin problems efficiently.
• Dual Anti-oxidation Mechanism, Anti-aging & Anti-photoaging: Possesses dual free radical scavenging and antioxidant protection capabilities. It resists UV-induced photooxidative damage and environmental oxidative stress, improves sun dullness and fine lines, and delays skin aging.
• Formula Active Stabilization, Prevent Ingredient Failure: Unique active protection performance, effectively stabilizes active ingredients such as VC, prevents oxidative discoloration and failure of compound formulas, improves product stability and extends shelf life.
• Mild Anti-inflammatory & Soothing, Suitable for All Skin Types: Natural mild phenolic structure, non-irritating and non-sensitizing. It relieves oxidative redness and skin sensitivity, balances fragile skin, and realizes safe brightening without damaging the skin barrier.
• Improve Translucent Skin, Uniform Complexion: Targets dullness, yellowish and uneven skin tone, fades shallow pigmentation, brightens skin translucency, and creates clear and bright skin texture.

It not only has efficient brightening and dullness-removing efficacy, but also has dual functions of antioxidant anti-aging and formula active stabilization. It solves the pain points of traditional brightening ingredients such as single efficacy, easy oxidation and poor stability, and is a multi-functional high-end brightening raw material.
• Q2: What is the recommended addition ratio of Hydroxycinnamic Acid in skincare formulas?
A2: Conventional brightening maintenance products: 0.02%-0.1%; High-efficiency whitening essence formulas: 0.1%-0.3%; Antioxidant anti-aging products: 0.05%-0.2%; VC compound stabilizing formulas: 0.03%-0.15%; Mask essence formulas: 0.05%-0.2%. It is recommended to dissolve with ethanol first and add at low temperature (below 40℃) to ensure uniform dispersion and maximum activity retention.
• Q3: Will Hydroxycinnamic Acid cause formula discoloration or irritation?
A3: High-purity Hydroxycinnamic Acid is pure off-white crystal powder with stable properties. After standardized auxiliary dissolution and low-temperature feeding process, the formula is clear and transparent. It has mild phenolic structure without irritation and sensitization. Strictly controlling the addition amount will not cause product discoloration, precipitation or skin irritation, with high safety.
