Preservatives are under constant scrutiny by consumers and the cosmetics industry with many usage restrictions and bans now in place. The more traditional preservative systems such as Parabens and MIT/ MIC have been the subject of much negative publicity, making the drive towards alternative preservation more relevant than ever.
This is why Infinity Ingredients are proud to have Dr. Straetmans, one of the market leaders within this category with more than 20 years experience, as their partner within the UK.
Dr. Straetmans Dermosoft® products can be used to support, boost or replace traditional preservative systems. To prove the efficacy of these products, Dr. Straetmans offers a microbiological service as part of their customer service to enable cosmetic formulators to make the best choice for successful preservation.
The Dermosoft® range offers more than just preservation; some variants have selected activity against specific micro organisms that can cause skin disorders such as dandruff, Athlete’s foot, acne and body odour.
Let’s look at the organic acids first: these ingredients are able to destroy germs by the continuous acidification of cell cytoplasm, increasing the osmotic pressure due to intake of electrolytes (e.g. Na+) and by the loss of energy in the active transport mechanism within the membrane.
Small amphiphilic molecules that replace membrane lipids. Due to their high surface activity and incompatible size they work by destabilising the membrane from the outside. The active compound is not consumed and as such remains active in the formulation and therefore offers a long lasting mode of action.
Economical preservative range for ‘free from’ products. Three easy to use liquids are offered as part of this range.
