Aloe Vera Gel
Aloe Vera Gel is a clear, jelly-like substance extracted from the inner leaf of the Aloe vera plant. It is widely used in skincare for its soothing, hydrating, and healing properties. Rich in vitamins (especially A, C, and E), enzymes, and amino acids, Aloe Vera Gel is commonly applied to treat sunburns, minor cuts, skin irritation, and dryness. It also has mild anti-inflammatory and antibacterial effects, making it a popular natural remedy in both cosmetic and medicinal products.
Alpha Arbutin
Alpha Arbutin is a biosynthetic active ingredient derived from hydroquinone and glucose. It is widely used in cosmetic and skincare formulations for its skin-brightening and spot-reducing properties. Alpha Arbutin inhibits tyrosinase, an enzyme involved in melanin production, thereby helping to reduce pigmentation, dark spots, and uneven skin tone. It is more stable and effective than its beta counterpart and is suitable for all skin types, including sensitive skin.
Ascorbic Acid
Ascorbic Acid, commonly known as Vitamin C, is a water-soluble vitamin and potent antioxidant essential for collagen synthesis, immune function, and protection against oxidative stress. It is widely used as a nutritional supplement, food preservative, and additive to enhance shelf life and nutritional value. Naturally present in citrus fruits and various vegetables, ascorbic acid is also important in pharmaceutical, cosmetic, and animal feed industries due to its health benefits and preservative qualities.
Cetrimide Powder
Cetrimide Powder is a high-purity quaternary ammonium compound widely used for its antiseptic, disinfectant, and surfactant properties. It is a cationic surfactant derived from cetyltrimethylammonium bromide and appears as a white to off-white crystalline powder with a slight characteristic odor. Known for its excellent antimicrobial efficacy against bacteria and fungi, cetrimide is frequently incorporated in pharmaceutical, personal care, and industrial formulations. It acts as a bactericidal agent, detergent, and emulsifier, providing effective cleaning and disinfecting action.
Ferulic Acid
Ferulic Acid is a naturally occurring hydroxycinnamic acid classified as a phenolic compound with potent antioxidant properties. It exists as a pale yellow to light brown crystalline powder with a faint characteristic odor. Ferulic Acid is commonly found in the cell walls of various plants such as rice bran, wheat, oats, coffee, apples, and fruits, where it plays a role in plant structural integrity and defense against environmental stress. It is valued across multiple industries—cosmetics, pharmaceuticals, nutraceuticals, food, and agriculture—due to its ability to neutralize free radicals, absorb UV radiation, and exhibit anti-inflammatory and antimicrobial activities.
L-Glutathione Reduced
L-Glutathione Reduced is a tripeptide composed of glutamine, cysteine, and glycine, present in cells as a vital antioxidant. It appears as a white to off-white crystalline powder and plays a key role in protecting cells from oxidative stress by neutralizing free radicals and reactive oxygen species. Reduced glutathione (GSH) is the active form that participates in cellular detoxification, immune support, and regeneration of other antioxidants. It is widely used in pharmaceutical, cosmetic, and food industries due to its potent antioxidant properties and skin-brightening effects.
Magnesium Ascorbyl Phosphate
Magnesium Ascorbyl Phosphate (MAP) is a stable, water-soluble derivative of Vitamin C, combined with magnesium. It offers antioxidant benefits and skin-brightening effects with improved stability and lower irritation compared to pure ascorbic acid. Widely used in cosmetics and pharmaceuticals, MAP promotes collagen synthesis, reduces pigmentation, and protects skin from oxidative damage.
