COMPLEX B HERBAL EXTRACT

Physical tests

On the freshly prepared product (complex B extract) microbiological and rheological analyses were performed; its pH value was measured and sample was physically examined.

• It is seen as a homogenous solution and no phase separation was observed.
• Herbal extract is off-yellow.
• pH value of complex B was 4.92. This pH value is suitable for applications on the skin.

• Viscosity of complex B was 716 mPas sec. It is suitable for applications on the skin.
• Contaminants obtained from microbiological analysis are non-pathogenic and very common ones.

Stability tests storage conditions

Product (complex B) samples were stored under conditions; 60% relative humidity and 4oC±1oC, 25oC±0.1oC, 40oC±0.1oC, -40oC±0.1oC.

• No changes in appearance or phase separation were observed.
• Off yellow color of the extract became darker in every medium in speeded up stability conditions (fridge, room temperature, strove, acclimatization cabin). This indicates preparation should be filled in oxygen-free mediums and be kept in tightly sealed, colored vessels with small application holes.
• Viscosity changes were observed during storage of complex B. Yet the interval of change was not extensive enough to provide problems for application.
• No microorganism that might cause problems in respect for applications were observed in microbiological analyses.
