Unlike L-Ascorbic Acid, it does not readily degrade in formulas containing water.  It is considered light-stable and oxygen-stable. Studies of MAP in aqueous solutions indicate it retains over 95% of its potency at 40°C without any pH adjustment.\u003c\/p\u003e\n\u003cp\u003eBy inhibiting tyrosinase activity, MAP is capable of suppressing skin pigmentation, making it effective in whitening dark skin, or areas of dark skin.  It should be noted, one study indicated it might be needed at a concentration of 10% to be effective at inhibiting melanin production\u003csup\u003e1\u003c\/sup\u003e.\u003c\/p\u003e\n\u003cp\u003eUnlike Ascorbyl Palmitate, Magnesium Ascorbyl Phosphate (MAP) appears to have the same potential to boost skin collagen synthesis as does Ascorbic Acid, but at lower concentrations. For those with sensitive skin or those wanting to avoid the exfoliating effects of highly acidic Ascorbic Acid, MAP may be the preferred choice.\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eApplications\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSuncare and after-sun products\u003c\/li\u003e\n\u003cli\u003eMakeup products\u003c\/li\u003e\n\u003cli\u003eSkin lightening products\u003c\/li\u003e\n\u003cli\u003eAnti aging products\u003c\/li\u003e\n\u003cli\u003eCreams and lotions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eThis is a cosmetic raw material and is meant for external use only.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan style=\"font-weight: bold;\"\u003eINCI:\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eMagnesium Ascorbyl Phosphate\u003c\/p\u003e\n\u003cp\u003e\u003csup\u003e1\u003c\/sup\u003eSource:\u003cspan\u003e \u003c\/span\u003e\u003cspan style=\"font-style: italic;\"\u003ePhotochemistry and Photobiology\u003c\/span\u003e, June 1998, pages 669–675; and\u003cspan\u003e \u003c\/span\u003e\u003cspan style=\"font-style: italic;\"\u003eJournal of Pharmaceutical and Biomedical Analysis\u003c\/span\u003e, March 1997, pages 795–801\u003c\/p\u003e\n\u003ch5\u003eSDS \u0026amp; Tech Data\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0026\/8317\/5001\/files\/Specification_Sheet_-_Magnesium_Ascorbyl_Phosphate_MAP.pdf?v=1771001315\" target=\"_blank\" title=\"Specification Sheet - Magnesium Ascorbyl Phosphate (MAP)\" rel=\"noopener\"\u003eMagnesium Ascorbyl Phosphate (MAP) Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0026\/8317\/5001\/files\/sds_magnesium_ascorbyl_phosphate_20260213.pdf?v=1771001269\" target=\"_blank\" title=\"SDS Magnesium Ascorbyl Phosphate (MAP)\" rel=\"noopener\"\u003eMagnesium Ascorbyl Phosphate (MAP) SDS \u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFormulation Guide\u003c\/h5\u003e\n\u003cp\u003e\u003cspan\u003eFormulation Guidelines\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMagnesium Ascorbyl Phosphate (MAP) may discolor in formulations with a pH below 6, so is best used in products with a final formulation pH between 6.0 - 7.0.\u003c\/li\u003e\n\u003cli\u003eThe solubility of MAP in water is 154g\/l at 25C\/77F (that's at most 15.4%)\u003c\/li\u003e\n\u003cli\u003eMAP is stable at 80C\/176F for up to 20 hours; this means that it should withstand heating to this temperature for short periods in formulations without a problem.  Therefore, it can be added to the water phase prior to heating.\u003c\/li\u003e\n\u003cli\u003eYou can also predisperse it in a small amount of distilled water and add at the end of the formulation process.\u003c\/li\u003e\n\u003cli\u003eIf you're having trouble dissolving MAP in water, warming the solution to about 40°C (104°F) will help.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan style=\"font-weight: bold;\"\u003eTypical usage rate:\u003c\/span\u003e  0.2 - 3%, up to 10%\u003cbr\u003e\u003cspan style=\"font-weight: bold;\"\u003eAppearance:\u003c\/span\u003e  White to Pale Yellow Powder\u003c\/p\u003e","brand":"Undisclosed","offers":[{"title":"1 oz -  $15.95","offer_id":13079627300953,"sku":"MAP-01","price":15.95,"currency_code":"USD","in_stock":true},{"title":"4 oz - $59.95","offer_id":13079627333721,"sku":"MAP-04","price":59.95,"currency_code":"USD","in_stock":true},{"title":"8 oz - $110.95","offer_id":13079627268185,"sku":"MAP-08","price":110.95,"currency_code":"USD","in_stock":true},{"title":"1 lb - $201.95","offer_id":13079627366489,"sku":"MAP-1","price":201.95,"currency_code":"USD","in_stock":true},{"title":"5 lbs - $939.95","offer_id":13079627399257,"sku":"MAP-5","price":939.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0026\/8317\/5001\/products\/neodefend_0a431d2d-6202-49b8-9853-f430e35319db.JPG?v=1571722089","url":"https:\/\/lotioncrafter.live\/products\/magnesium-ascorbyl-phosphate-map","provider":"Lotioncrafter","version":"1.0","type":"link"}
