Magnolia Bark Extract (98%)

INCI: Magnolia Officinalis Bark Extract

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.

Tip for processing
If you want to use Magnolia Extract  for its antimicrobial properties and thus for product protection, you must use a solubiliser. Only then can it show its full antimicrobial potential.
Pentylene glycol is well suited as a solubiliser. This is because it is soluble in both water and oil.  You then add this solution of Magnolia Extract 98 and pentylene glycol to the water.  Now Magnolia Bark Extract  can develop its full effect.
