Biochemical Formulation Development and Evaluation of Face Mask Stick for Skin Ailments with Pinus pinaster (pine bark oil)

Abstract

In recent years, skin care has gained significant attention with more individuals. The demand for natural and effective skincare products has continued to grow in recent years. A face mask is a skin care product that effectively removes excess oil and dirt from the skin. It also gives hydration and moisturizing effect to skin. The aim of present work was formulation, development and evaluation of Face Mask Stick with Pine bark oil as an active ingredient. It is reported that, Pine Bark oil helps to reduce skin pigmentation, improve skin hydration, enhance brightness, skin rejuvenation and gives regenerative effect to the skin. The idea of formulation of face mask stick with pine bark oil as an active was conceptualized by a novel application method for skincare, i.e., face mask stick unlike traditional face mask format such as creams, gels or sheet masks. Face mask stick gives moisturizing effect and cleansing effect, it is travel friendly, time saving approach with mess-free application on skin. Pine bark oil was validated by analysis of color, odor, solubility, boiling point, refractive index and specific gravity. Different concentrations of pine bark oil were used to develop face mask stick and final formulation with 0.5% pine bark oil, was evaluated for parameters such as pH, colour, odour, homogeneity test, breaking load test, softening point test, disintegration time test, Total Microbial Count study. Also, stability study of final product was carried out; changes in parameters like colour, odour and texture at three different temperatures, i.e., in refrigerator temperature (at 4⁰C), at room temperature and at oven temperature (at 45⁰C) were recorded for 15 days at interval of 1 day, results showed that the product was stable with respect to colour, odour and texture.  Subjective evaluation was carried out to study the functional parameters like appearance, ease of spreadability, improvement in texture, moisturizing effect, hydration and skin irritancy test on the panel of human volunteers. The study showed that face mask stick with 0.5% pine bark oil as an active gives satisfactory effect in terms of cleansing effect, moisturizing effect, skin hydration, without irritancy on skin.
