Magnolia Bark Extract 98% consists of half the pharmacologically active components Magnolol and Honokiol. The extract has a strong antimicrobial, antibacterial and anti-inflammatory effect. Used in acne treatment, Magnolia Bark Extract works very efficiently against acne-causing germs without irritating the skin. As it has a significantly higher antioxidant effect than alpha-tocopherol, it is excellently suited for sun protection products. Oxidation products are neutralized and thus skin damage is avoided.
In fats and oils it helps as a booster - similar to vitamin C palmitate - to prolong the effect of mixed tocopherols and thus the shelf life of the fat/oil.
Magnolia Bark Extract has a very good effect against bacteria, yeasts and fungi even at very low dosages (Ph independent). The extract is soluble in alcohol and fatty oils (not water soluble). It works particularly well in combination with Pentylene Glycol natural and Glyceryl Caprylate (GMCY).
Magnolia Bark Extract is hydroscopic and should be protected against wetness.
