Microcare DB is a blend of benzyl alcohol and dehydroacetic acid. Also known as Geogard 221 or Mikrokill.

It is a mild natural preservative, which is approved by BIO-GRO Organic Certification for skincare and cosmetics. It must be used at a pH of less than 6, and preferably about 5, to have optimal effectiveness.

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:
• Shampoos
• 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.
