Formulation and Evaluation of Licorice Shampoo in Comparison with Commercial Shampoo

Application of Plant Surfactants as Cleaning Agents in Shampoo Formulations

With the increased demand for sustainable, hypoallergenic products, plant surfactants are a promising, eco-friendly option for cleaning products due to their low toxicity or even the absence of toxicity. In the present study, surfactant-rich extracts from Chenopodium quinoa, Glycine max, and Malpighia emarginata were assessed for their stability, antioxidant capacity, toxic potential, and cleaning potential in shampoo formulations. The surfactants in the extracts were isolated and characterized by NMR, UV-Vis, and FTIR spectroscopy. The results demonstrated that the extracts remained stable within the temperature and pH ranges tested. The antioxidant properties were also determined. In the analysis of irritation potential, G. max and C. quinoa exhibited low toxicity and no toxicity, respectively. The cleaning potential analysis confirmed that the extracts could be used as primary surfactants. Seven shampoo formulations were developed, which showed potential to reduce surface tension to the range of 27.1–31.7 mN/m and interfacial tension to the range of 5.4–7.3 mN/m. The wettability, percentage of solids, density, pH, and dirt dispersion of the formulas were within standard ranges, and the sebum removal capacity of the seven formulations was similar to or even better than that of a commercial shampoo.

Advantages of Hyaluronic Acid and Its Combination with Other Bioactive Ingredients in Cosmeceuticals

This study proposes a review on hyaluronic acid (HA) known as hyaluronan or hyaluronate and its derivates and their application in cosmetic formulations. HA is a glycosaminoglycan constituted from two disaccharides (N-acetylglucosamine and D-glucuronic acid), isolated initially from the vitreous humour of the eye, and subsequently discovered in different tissues or fluids (especially in the articular cartilage and the synovial fluid). It is ubiquitous in vertebrates, including humans, and it is involved in diverse biological processes, such as cell differentiation, embryological development, inflammation, wound healing, etc. HA has many qualities that recommend it over other substances used in skin regeneration, with moisturizing and anti-ageing effects. HA molecular weight influences its penetration into the skin and its biological activity. Considering that, nowadays, hyaluronic acid has a wide use and a multitude of applications (in ophthalmology, arthrology, pneumology, rhinology, aesthetic medicine, oncology, nutrition, and cosmetics), the present study describes the main aspects related to its use in cosmetology. The biological effect of HA on the skin level and its potential adverse effects are discussed. Some available cosmetic products containing HA have been identified from the brand portfolio of most known manufacturers and their composition was evaluated. Further, additional biological effects due to the other active ingredients (plant extracts, vitamins, amino acids, peptides, proteins, saccharides, probiotics, etc.) are presented, as well as a description of their possible toxic effects.

Organoleptic and physicochemical properties of natural-based herbal shampoo formulations with Cyclea peltata as a key ingredient

BACKGROUND

Synthetic shampoos have toxic chemical agents like chemicals such as parabens and sodium lauryl sulfate which damage the hair. To combat this issue, the use of natural herbal shampoos, as opposed to synthetic shampoos, is becoming increasingly popular. One of the many medicinal plants present in Karnataka and Kerala is Cyclea peltata. This plant has long been known to assist in wound healing, allergy relief, and hair and scalp improvement, as well as serving as a coolant for hair applications.

OBJECTIVE

The key subject of this research was the preparation of plant extracts and fermentation of Cyclea peltata leaf extract with Lactobacillus plantarum, resulting in the formulation of an herbal shampoo.

METHOD

The leaf extract contained alkaloids, flavonoids, tannins, phenolic acid, saponins, and proteins, according to previous research by this group. The fermented product showed the presence of lactic acid, which was a boon for shampoo base as it protects the hair from the sunlight and improves the texture and strength of hair fibers. Cyclea peltata was used as the main ingredient in herbal shampoo formulations, along with other herbal ingredients, and the formulated shampoo was characterized for its different organoleptic (Color, odor) and physicochemical properties (pH, solid content, wettability, emulsification, and foam stability) to find the best formulation.

RESULT

Formulation H2 showed better organoleptic and physicochemical properties and thus was chosen as the best formulation among the 11 formulations.

CONCLUSION

Formulation H2 is regarded as the best formulation based on the results of the physicochemical tests (Pleasant odor, pH 3.01, solid content of 5.75%, wettability of 1.68 s, and percentage emulsification of 68.75%).
