Every time 50 mg of hydrogel masks were obtained,
which were prepared with the following technique: carbomer
was dispersed in water by gently scattering it on
the surface of water, allowing it to be moisturized (for at
least 10 min, while observing the behavior of carbomer),
then briefly mixed. Ingredients of phase B were added and
mixed thoroughly using amechanical stirrer Eurostar Digital
(Mischen IKA) at a low speed for 20 min. Then, D-panthenol
with silicone was added (and peptide dissolved in water in the case of hydrogels including peptide). Subsequently
everything was thoroughly stirred for 10 min.
Value of pH was checked and at the final stage triethanolamine
was added until the pH reached about 6. In
this process no dye nor fragrance was used. Finished products
were tightly sealed and stored in the fridge at 5°C.
