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.
