After completion of the melting, the dyestuff, depending on its solubility, was dissolved either in oil or in water and then added to the wax mixture. Sapodilla fruit extract and the selected flavour were then added and the mixture was stirred thoroughly to achieve a smooth and homogenized texture. The final mixture was poured into clean, preoiled molds and allowed to cool to facilitate wax contraction and ready removal of the consolidated lip balm.EXAMPLE 3: EvaluationsColor RatingThe color of the prepared lip balm formulation was evaluated by visual inspection. Observations were made in both natural daylight and artificial lighting to ensure color consistency. The evaluation contributed to discern any discoloration or instability of the formulation. Color controls were performed during the first formulation and repeated periodically during the stability study. In this way, it was ensured that the visual aesthetic remained intact during the entire durability period.The Q2 formulation retained a yellowish color throughout the study. No signs of discoloration or color tone changes were observed, indicating excellent color stability.Odor ratingThe odour was organoleptically assessed by a group of volunteers immediately after formulation and during the stability test. The balsam was gently heated between the fingers prior to sniffing to release aromatic compounds. The test ensured that no unpleasant, rancid or chemically degraded odors developed.The evaluations were repeated during storage at different temperatures. In this way, the durability of the fragrance over time could be evaluated.The lip balm retained its fresh, colored scent throughout all test intervals. No unpleasant or altered odours were observed, confirming good odour stability.Appearance: AppearanceThe appearance was visually and titably checked for a uniform texture and the absence of cracks, bubbles or phase separation. The evaluation was carried out after consolidation of the balsam and after a plurality of storage times. Gloss, uniform surface area and structural integrity were criteria for positive evaluation. The changes were observed under normal illumination. The evaluation provided consumer-responsive presentation and texture over a longer period of time.The results show that the Q2formulation consistently had a smooth, glossy surface. No visible imperfections such as cracks or bubbles were observed, suggesting excellent physical stability.pH EvaluationTo measure pH, a small sample of the balsam was emulsified in distilled water. A calibrated digital pH meter was used to obtain accurate measurements. This step ensured that the formulation is skin-compatible and does not irritate the lips. The measurements were made during the formulation and again during the stability study. Consistent pH was a key indicator of chemical stability.The results show that the pH of the Q2 lip balm was 6.8, an ideal range for application to the lips. No significant deviation was found, confirming pH stability.EXAMPLE 3: Determination of melting pointSmall amounts of the lip balm were placed in capillary tubes and placed in a temperature controlled water bath. The temperature was slowly increased and the point at which the balsam began to melt was noted. This method confirmed the ability of the product to withstand normal and elevated temperatures. The tests were repeated during the phases of the stability study. The thermal resistance confirmed the durability and usability.The results show that batch Q2 melted throughout at 70°C. This stable melting point confirmed the thermal robustness of the formulation.EXAMPLE 4: Irritation TestA patch containing the balsam was applied to the inner forearm of healthy volunteers. The skin was examined after 1 hour and again after 6 hours for signs of irritation, redness or inflammation. The test evaluated the dermal safety of the formulation. Only healthy, non-allergic persons participated. Observations were documented by the same evaluator to ensure consistency.No irritation, redness or discomfort was observed during the test. This confirmed that the product is safe for topical application.EXAMPLE 5: Dispersibility TestThe balsam was clamped between two glass slides under a fixed weight. The dispersibility and uniformity of the film were observed. Dispersibility was evaluated as good, moderate or poor depending on uniformity and structure. The tests were repeated at different times of storage. This method ensured that the balsam could easily be applied during its entire durability period.The results show that the Q2formulation had good dispersibility. It was able to be applied uniformly without breaking, thus confirming desirable consistency and user-friendliness.EXAMPLE 6: Normal Stability Study (Refrigerator):The Q2 lip balm formulation was stored in a refrigerator at a constant temperature of about 10°C. Organoleptic properties such as appearance, color, odor, spreadableness and melting point were observed and recorded on days 1, 5, 10, 15 and 20. The paintability was rated on a standard rating scale: G (good), I (moderate), and B (poor) based on the uniformity and structural integrity of the application. The melting point was measured by a capillary tube method with temperature controlled heating.The results show that the lip balm stored in the refrigerator exhibited a moderate appearance change (rated "M") during the 20-day period, but retained a normal yellow color and odor without any noticeable change. The spreadableness was evaluated as good (G) throughout up to day 15, a slight shift to moderate (I) being present on day 20, which indicates a slight change in texture due to the prolonged exposure to cold. The melting point was between 70 and 71.5°C, indicating slight variations but general thermal stability under cooling conditions.EXAMPLE 7: Normal Stability Study (Room Temperature)Q2 lip balm was stored at room temperature (~25° C.) and examined at regular intervals on days 1, 5, 10, 15 and 20. The appearance, color, odor, spreadableness and melting point were observed. Dispersibility was evaluated by applying the product to a glass slide and observing the ease and uniformity of spreading.At room temperature, the lip balm initially had a moderate appearance but turned increasingly into a highly modified appearance (IM) until 10th day, indicating a visible change in physical appearance. The color and odor remained normal throughout the study. The spreadableness was good (G) in the first 10 days, but on day 15 and 20 it decreased to modified (M), which indicates a slight deterioration of the texture. The melting point remained relatively constant and ranged between 70°C and 71.6°C indicating satisfactory thermal stability.EXAMPLE 8: Normal Stability Study (Hot Air Oven):The Q2 lip balm was stored in a hot air oven at 45°C to simulate elevated temperature conditions. Observations on appearance, color, odor, spreadableness and melting point were made on days 1, 5, 10, 15 and 20. Changes were recorded to understand how heat stress has an effect on product stability over time.When stored in the hot air oven, the lip balm showed a normal appearance up to day 15, which changed to a moderate change (M) up to day 20. The color started to deteriorate from day 10 and showed a change (M) in hue. The odour remained stable (normal) over all times. However, the paintability decreased drastically and changed from good (G) on day 1 and day 5 to poor (B) on day 10 indicating structural degradation under the application of heat. The melting point reached a maximum of 74°C on day 5, followed by a decrease to 70°C on day 20, indicating the effects of thermal stress.ExamplesA composition of a vegetable lip balm comprising Sapodilla (Manilkara zapota) fruit extract:2 g of beeswax,2 g of cocoa butter,2 g shea butter,2 g of Sapodilla fruit extract,1 ml of coconut oil,0.5 ml vitamin E oil and0.5 g of honey,wherein the composition has a wax:butter:oil ratio of about 1:1:1 and exhibits improved texture, suppleness, dispersibility and thermal stability with a melting point of about 70°C and a pH of 6.8 suitable for topical application.
