Product name: 3-O-Ethyl ascorbic acid Synonyms: VC ethyl ether, 3-O-Ethyl-L-ascorbic Acid, 3-O-Ethyl Ascorbyl Ether, Ethyl ascorbic acid INCI name: - CAS No.: 86404-04-8 EINECS: 617-849-3 Quality: assay 99% up by HPLC Molecular formula: C8H12O6 Molecular weight: 204.18   Description: 3-O-Ethyl-L-Ascorbic Acid, or Ethyl Ascorbic Acid is a molecule produced by modifying Ascorbic Acid, commonly known as Vitamin C. This modification is done to increase the molecule’s stability and enhance its transport through skin, as pure Vitamin C is easily degraded. In the body, the modifying group is removed and Vitamin C is restored in its natural form. Thus, Ethyl Ascorbic Acid retains the benefits of Vitamin C, such as antioxidant activity. Furthermore, it is even more potent in reducing skin darkening after UV exposure. It even has some additional effects, not observed in pure Ascorbic Acid, such as promoting nerve cell growth or reducing chemotherapy damage. Finally, the slower release also ensures that no toxic effects are observed when using this Vitamin C derivative.   Specification (assay 99% up by HPLC): Items Specifications Appearance White crystalline powder Assay ≥99% Metling point 110.0-115.0℃ PH (3% water solution) 3.5-5.5 Free of VC ≤10 ppm Heavy metal ≤10 ppm Loss on drying ≤0.5% Residue on ignition ≤0.2% Production capacity: 1000kg/month Storage condition: Stored in cool, dry place, room temperature.

Product name: alpha-Arbutin Synonyms: Arbutin, α-Arbutin INCI name: alpha-Arbutin CAS No.: 84380-01-8 EINECS: 209-795-0 Quality: assay 99.5% up by HPLC Molecular formula: C12H16O7 Molecular weight: 272.25   Description: Extracted from plants such as bearberries, blueberries, and cranberries, alpha arbutin is a safe skin brightening ingredient which helps to fade scars and pigmentation left behind by breakouts and sun damage. Alpha arbutin is frequently marketed as a safer alternative to hydroquinone (a popular skin-lightening ingredient that has been banned in Europe and Australia). It has similar results in brightening skin but without the dangerous bleaching process. Instead, it reduces skin’s pigment production by suppressing the enzymes that stimulate melanin. This also slows down the process by which UV light causes pigmentation, so it both prevents and treats pigmentation issues.    Specification (assay 99.5% up by HPLC): Item Specification Appearance White crystalline powder Assay ≥99.5% Melting point 201 to 207±1℃ Clarity of water solution Transparency, colorless, none suspended matters.

Product name: alpha-Lipoic Acid Synonyms: α-Lipoic Acid, alpha-Lipoic Acid, ALA INCI name: - CAS No.: 1077-28-7 EINECS: 214-071-2 Quality: USP43 Molecular formula: C8H14O2S2 Molecular weight: 206.33   Description: Alpha-lipoic acid is an organic compound found in all human cells. It’s made inside the mitochondrion — also known as the powerhouse of cells — where it helps enzymes turn nutrients into energy (1Trusted Source). What’s more, it has powerful antioxidant properties. Alpha-lipoic acid is both water- and fat-soluble, which allows it to work in every cell or tissue in the body. Meanwhile, most other antioxidants are either water- or fat-soluble (2Trusted Source). The antioxidant properties of alpha-lipoic acid have been linked to several benefits, including lower blood sugar levels, reduced inflammation, slowed skin aging, and improved nerve function. Alpha lipoic acid is also known as thioctic acid; it’s extremely vulnerable to degradation by sunlight. Higher concentrations (5% or greater) are capable of causing a burning or stinging sensation on skin.    Specification (USP43): Item     Specification Appearance Slightly yellow crystalline powder Identification Meets the requirements Melting point 60.0~62.0℃ Specific rotation -1.0° to +1.0c Loss on drying ≤0.20% Residue on ignition ≤0.10% Heavy Metals ≤10ppm Lead ≤3ppm Cadmium ≤1ppm Mercury ≤0.1ppm Chromatographic purity   Single impurity ≤0.10% Total impurities ≤2.0% Limit of polymer content Conforms Residual solvent by GC   Cyclohexane ≤3880ppm Ethyl acetate ≤500ppm Total plate counts ≤1000CFU/g Moulds and yeasts ≤100CFU/g E.coli/Salmonella Absence/g Staphylococcus aureus Absence/g Particle size 100% through 40 mesh Loose bulk density  0.35g/ml min Assay 99.0%~101.0%   Production capacity: 1000kg/month Storage condition: Stored in cool, dry place, room temperature.

Product name: Bimatoprost Synonyms:-  INCI name: Bimatoprost CAS No.: 155206-00-1 EINECS: 642-890-9 Quality: assay 99.5%-102.0% up by HPLC Molecular formula: C25H37NO4 Molecular weight: 415.57   Description: Individuals may even use eyelash transplantations to improve the appearance of their eyelashes. The unique properties of eyelashes (e.g., relatively long telogen and short anagen phases compared with scalp hairs, slow rate of growth, and a lack of influence by androgens) may allow for specific aesthetic interventions to improve the appearance of natural eyelashes. Some over-the-counter (OTC) products may contain prostaglandin analogs that can affect eyelash growth, but neither the safety nor efficacy of these OTC cosmetics has been fully studied. Originally indicated for the reduction of intraocular pressure, the synthetic prostaglandin analog bimatoprost was recently approved for the treatment of hypotrichosis of the eyelashes. In a double-blinded, randomized, vehicle-controlled trial, bimatoprost safely and effectively grew natural eyelashes, making them longer, thicker, and darker. Bimatoprost was generally safe and well tolerated and appears to provide an additional option for individuals looking to improve the appearance of their eyelashes.
