Formulation and Evaluation of Sunscreen Cream

Abstract

Aims: The purpose of sunscreen (anti-sunburn and suntan) preparations is to assist the skin’s painful effects, and
the purpose of anti-burn preparations is to minimize the harmful effects of sunburn. The materials that are used for
the above purpose are known as sun tanning agents and sunburn preventive agents, respectively. In combination,
these are known as sunscreens. Materials and Methods: Ingredients such as zinc oxide, raspberry oil, jojoba oil,
shea butter, glycerin, liquid paraffin, tween 80, methyl paraben, rose oil, and distilled water were used. The zinc
oxide, raspberry oil, and jojoba oil were used as sunscreen agents; shea butter and liquid paraffin and polyethylene
glycol were used as emollients; glycerin was used as a glossy-effect and moisturizing agent; Tween 80 was
used as surfactant; methyl paraben was used as preservative; rose oil was used as flavoring agent; and distilled
water was used as aqueous phase. A total of six formulations were developed with different compositions of
ingredients, ranging from F1 to F6, to select the best formulation for the advancement scope of the study. The
prepared formulations were evaluated for suitable parameters such as physical appearance/visual inspection,
skin irritation, determination of pH, perfume stability, spreadability, viscosity, and sun protection factor (SPF).
Results and Discussion: All the formulations showed a white appearance with a pleasant odor and good perfume
stability. The pH for F1 to F6 was in the range of 6.3–7.0, and all the formulations did not show any skin irritation,
and spreadability ranged from average to very good. The viscosity values range between 5020 cp and 8912 cp.
For the SPF, an in vitro method was performed using the Mansur equation. Conclusion: By considering the values
from the evaluation of all from F1 to F6, the F6 formulation was selected as the best formulation.
