Cosphaderm® Magnolia Extract 98 is a great antimicrobial agent, especially against yeasts and moulds. In addition, this special multifunctional has numerous healing properties.
But, it seems complicated to incorporate this hydrophobic extract into a cosmetic formulation. The extract is highly non-polar and therefore insoluble in water. However, it must be incorporated into the water phase, as this is the phase that is attractive to germs, so this phase must be preserved.
The answer is simple.
We use pentylene glycol as a solubiliser. Pentylene glycol is soluble in both water and oil and acts as a bridge over which the magnolia extract can pass from the oil into the water phase. We now add this solution of Magnolia Extract 98 and pentylene glycol to the water and the extract no longer precipitates. If the magnolia extract is used for its antimicrobial properties and thus for product protection, there must be a solubiliser. This is the only way it can show its full antimicrobial potential.

WHAT ARE THE SPECIAL ACTIVE PROPERTIES OF MAGNOLIA EXTRACT 98?
Our magnolia extract Magnolia extract is obtained from the bark of the magnolia tree by supercritical CO2 extraction and then recrystallised ethanolically. Using this method, we obtain an extract that consists of at least 49 % each of the two active ingredients honokiol and magnolol. This purification process results in a white powder - not a classic coloured extract, which could lead to discolouration of the final cosmetic product. In addition, our extract is highly pure and reproducible.
It is extremely effective against acne germs, which cause unpleasant itching, as well as against tooth decay and periodontitis. It is also a powerful antioxidant, anti-inflammatory and anti-ageing agent.
Because of these many properties, we always recommend Cosphaderm® Magnolia Extract 98, which, when used correctly, is a perfect, reproducible preservative with good healing properties.
