Chitosan hydrochloride based cream evaluation tests
Based on the physicochemical tests and sensory evaluation conducted on chitosan
hydrochloride-based cream, the results indicate positive findings which are discussed below:
1. Physico-chemical Tests :
• PH: The pH range of [5-6] is considered ideal for skincare products especially for
wound healing. This pH range is close to the natural pH of the skin, which helps
maintain the skin's barrier function and minimize the risk of irritation or disruption of
the skin's acid mantle.
• Viscosity: A viscosity value of 41959 mPas suggests that the cream has a relatively
high viscosity. This thick consistency is beneficial for certain applications, such as
wound healing or prolonged contact with the skin. A higher viscosity can provide a
more substantial barrier effect, enhancing the cream's moisturizing and protective
properties.
2. Sensory Evaluation :
• Visual Appearance: The white visual appearance of the cream is typically associated
with cleanliness and purity. The absence of any noticeable impurities or discoloration
indicates good quality control during production.
• Texture: The cream has a heavy texture, more similar to pomade than a traditional
cream. The variation in texture observed can be attributed to the inclusion of chitosan
hydrochloride, which contributes to an increase in viscosity, leading to a thicker and
more viscous texture. This specific texture characteristic is considered beneficial for
our cream intended for wound healing purposes.
• Odor: The absence of any odor in the cream is generally positive. It suggests that the
formulation is well-controlled and does not contain any unpleasant or irritating
fragrances.
