Formulation and Physicochemical Evaluation of Lab-Based Aloe adigratana Reynolds Shampoos

Abstract

Aloe L. species (Aloaceae) are ethnobotanically very valuable plants in many communities and civilizations. Nonetheless, very few species are extensively studied to explore their applications in the pharmaceutical and medical, cosmetic and personal care, food and beverage, and detergent industries. This study evaluated the characteristics and quality of lab-based shampoos formulated from the gel of Aloe adigratana Reynolds. Five shampoo formulations, 20 mL each, were prepared from A. adigratana gel in combination with one to two drops of coconut oil, jojoba oil, olive oil, pure glycerin oil, lemon juice, and vitamin E. Gel mass is prepared from mature, healthy leaves collected from the natural stand. The phytochemistry of the gel of the plant was also studied using phytochemical screening, proximate composition, and GC-MS analysis studies. Shampoo formulations with higher proportion (40 to 50% v/v) of A. adigratana gel were found to have comparable characteristics and qualities with a marketed shampoo. They fall within the range of acceptable quality parameters of commercial shampoos. The phytochemical studies of A. adigratana gel showed that the plant is the source of highly valued compounds for the preparation of shampoos. The gel was found to be rich in saponins as well as dodecanoic acid, hexadecanoic acid, and phytol. Future works should focus in the development of refined protocol towards formulating A. adigratana-based shampoos.

“…Furthermore, whereas compound 9 is important source of surfactants, compound 12 is used in saponification [ 46 ]. Similar fatty acids and essential oils were found in A. adigratana Reynolds [ 38 ].…”

“…Likewise, formulations with higher gel volume (8–10 mL) showed best consistency as the marketed shampoo. Varying the proportion of the gel did not bring about significant change in pH of the formulations—falling within the pH range of many marketed shampoos [ 38 – 40 , 47 ].…”

“…The gel masses were mixed with the ingredients according to the ratio indicated in Table 2 to prepare enough volume hair washing formulations [ 38 – 40 ]. Then, mixtures were homogenized one by one with magnetic stirrer at 400 rpm for 30 min at 30°C, and white smooth formulations were obtained.…”

“…The formulations were evaluated via sensory inspection and physical assessment methods based on procedures developed and used by many researchers against a marketed shampoo (product name: Aloe Vera Hair Shampoo; producer: Perfect Cosmetics, UAE; size: 5.5 mL; description: natural blend of Aloe vera extract and moisturizers; manufactured: 02/2018; expiry: 02/2021) [ 38 – 45 ].…”

“…The wetting times of the hair washing formulations were determined using the canvas disc method with some modifications [ 38 – 40 , 45 ]. One (1) inch diameter discs, weighing 0.45 grams, were cut out from a smooth garment (velvet).…”
