9.3 Production of the test emulsion DAY 0402
1. Provide water and heat to 75°C (167°F)
2. Mix and stir the Phase B raw materials so that the emulsifier is wetted by the oils, then heat to
75°C (167°F)
3. Shortly before emulsification, disperse Phase C into hot Phase B
4. Soak Phase B/C in Phase A and homogenize slightly
5. Add Phase D to the preparation and homogenize intensively
6. Cool preparation to 40°C (104°F) by stirring
7. Add Phases E and F by stirring and homogenize slightly again
8. Cool preparation to 30°C (86°F) by stirring
9.4 Data on stability
The cream DAY 0402 should reach a size in drops of approx. 1-5 micrometers.
The temperature stability evaluation carried out gave the following results:
after 1 month after 2 months after 3 months
at 3°C (37°F) o.k. o.k. o.k.
at 20°C (68°F) o.k. o.k. o.k.
at 40°C (104°F) o.k. o.k. o.k.
at 50°C (122°F) o.k. o.k. change in size of drops
Except at 50°C (122°F) there was no change in the size of the drops, viscosity changes, or change
in pH values during the stability tests.
At 50°C (122°F) no changes were note after two months. Only on the final evaluation after three
months was a change in droplet size noted.
9.5 Efficacy of DAY 0402 cream and a comparative cream measured against untreated
skin
9.5.1 General
A test emulsion DAY 0402 with 4% AQUARICH ® and a comparative emulsion with 0.1% hyaluronic
acid were measured against untreated skin. The measurement took place in three different
epidermal layers.
In the placebo the AQUARICH ® was totally replaced by glycerine (w/w). Thus the analyses were
calculated individually first and as a complete epidermis afterwards.
