    Ascorbyl glucoside
    Product name: Ascorbyl glucoside Synonyms: AA2G, Vitamin C Glucoside INCI name: - CAS No.: 129499-78-1 EINECS: - Quality: assay 98% up by HPLC Molecular formula: C12H18O11 Molecular weight: 338.26   Description: Ascorbyl glucoside is a stable form of vitamin C combined with glucose. When properly formulated and absorbed into skin, it breaks down to ascorbic acid (pure vitamin C). Ascorbyl glucoside functions as a time-release version of vitamin C (ascorbic acid), and therefore is more stable than traditional ascorbic acid. It is considered to have skin-lightening and anti-hyperpigmentation properties, thanks to an ability to suppress melanin production. Its skinbrightening capacities are attributed to an apparent ability to reduce pre-existing melanin levels (as in the case of freckles or age spots). Ascorbyl glucoside could also help promote collagen synthesis and help reduce skin inflammation. It is found in antiaging, anti-wrinkle, and sun care products.    Specification (assay 98% up by HPLC): Items Specifications Appearance White crystalline powder Identification In frared identification: Characteristic absorption peaks are 3300cm-1, 1770cm-1, 1110cm-1,1060cm-1 Loss on Drying (105℃, 3 hours) ≤1.0% PH (1% aqueous solution) 2.0-2.5 Melting point 158℃-163℃ Specific Rotation [α]20D +186°-+188.0° Sulfate Ash ≤0.2% Clarity of Solution Clear Color of Solution (3% aqueous solution, 400nm, 10mm) ≤0.01 Free Ascorbic Acid ≤0.1% Free Glucose ≤0.1% Heavy Metals (In Pb) ≤20ppm Arsenic ≤2.0ppm Assay (by HPLC) ≥98% Production capacity: 300kg/month Storage condition: Stored in cool, dry place, room temperature.

  • ascorbyl tetraisopalmitate in cosmetics
    ascorbyl tetraisopalmitate
    Product name: Ascorbic tetraisopalmitate Synonyms: Ascorbic tetraisopalmitate, VC-IP, BV-OSC, Vitamin C tetra-isopalmitate INCI name: - CAS No.: 183476-82-6 EINECS: 201-081-7 Quality: assay 95% up by HPLC Molecular formula: C70H128O10 Molecular weight: 1129.76   Description: Ascorbyl Tetraisopalmitate is an oil-soluble derivative of Vitamin C that can be used in higher concentrations without drawbacks. It is one of the most stable derivatives of Vitamin C but, being a derivative, its potency will not be directly comparable to pure L-Ascorbic Acid. It is provided in this oil-format formula in combination with Vitamin F, also known as essential fatty acids. Aside from the general benefits of pure Vitamin C, Ascorbyl Tetraisopalmiate has been shown to offer specific skin brightening benefits.    Specification (assay 95% up by HPLC): Item Specification Appearance Colorless to pale yellow liquid Odor Faint, Characteristic Assay ≥95% by HPLC Loss on Drying ≤0.5% Color (APHA) ≤100 Specific gravity(d20) 0.930-0.943 Refractive index(n25) 1.459-1.465 Heavy metals ≤20ppm Arsenic ≤2ppm Production capacity: 300kg/month Storage condition: Stored in cool, dry place, room temperature. Package material: drum Package size:1kg/drum, 5kg/drum, 10kg/drum, 25kg/drum
  • alpha lipoic acid bulk powder in cosmetics
    alpha-Lipoic Acid
    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.

  • alpha arbutin powder
    alpha-Arbutin
    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. PH 5.0~7.0 Specific optical rotation [α]D20=+175-185° Arsenic ≤2ppm Hydroquinone ≤10ppm Heavy metal ≤10ppm Loss on drying ≤0.5% Ignition residue ≤0.5% Phathogen Bacteria ≤1000cfu/g Fungus ≤100cfu/g   Production capacity: 1000kg/month Storage condition: Stored in cool, dry place, room temperature. Package material: carton, drum Package size:1kg/carton, 5kg/carton, 10kg/carton, 25kg/drum
  • ethyl ascorbic acid powder
    3-o-ethyl ascorbic acid
    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. Package material: carton, drum Package size:1kg/carton, 5kg/carton, 10kg/carton, 25kg/drum
