Chitosan hydrochloride addition
Chitosan hydrochloride was dissolved in purified water, centrifuged to 3200 tr/m for 25 min,
the supernatant was decanted, purified water was added to the tube and mixed well, then
centrifuged again.
The supernatant was carefully poured off, and the gel component was retained.
The decision to employ chitosan hydrochloride is based on its empirically proven heightened
antimicrobial properties and its compatibility with water-based skincare formulations.
Evaluation of the cream:
Our formulated cream, intended to closely resemble market skincare creams, must undergo a
series of rigorous quality controls. These encompass physicochemical evaluations such as
rheological analysis and pH stability assessment, as well as sensory evaluati ons, including
visual appearance, odor, and color assessments. These comprehensive controls ensure that our
cream meets the required standards in terms of its physical properties, stability, and sensory
attributes.
