INCI: Dehydroacetic acid and benzyl alcohol
This product is a direct substitute for Geogard 221
Microcare DB is a blend of an organic acid with benzyl alcohol which can be used for the gentle preservation of all personal care products. It is equally effective against a broad range of bacteria, moulds and yeasts and is ideal for Ecocert applications.
The preservative activity of Microcare DB is maximised at pHs below 6 where the organic acids exert their preserving activity in the undissociated state. Dehydroacetic acids act in a complementary nature by suppressing the growth and spore germination of yeasts and moulds whist benzyl alcohol acts as a broad spectrum bactericide.
Microcare DB is recommended for inclusion in both leave on and rinse off applications in the range 0.2 to 1.0% and should be dispersed with mixing as early as possible in the formulation process. It is most effective when incorporated during the cooling down phase of the manufacturing process to prevent vaporisation of benzyl alcohol. A pH greater than 6 during the manufacturing process does not cause any degradation of the actives, but for adequate protection the pH of the final product should be adjusted to 6 or less.
Because of the large variation in the composition of cosmetic products it is important that the preserving effectiveness is evaluated in the final formulation using appropriate microbial challenge tests.
Microcare DB is suitable for a wide range of personal care applications including:
• Hair conditioners
• Styling gels
• Liquid soaps
• Bath gels
• Moisturising creams
• Body creams and milks
• Suntan lotions
• Decorative cosmetics
Recommended usage rate is 0.2% - 1% in a pH of 6 or less.
Product should be dispersed during the cool-down phase of manufacturing in order to prevent vaporisation of the Benzyl Alcohol.
