Description:FIELD OF THE INVENTION
The present invention relates to the field of personal care and cosmetic products, and more particularly to a method for the preparation of herbal soap with enhanced antibacterial and anti-inflammatory properties. The invention specifically provides a natural and eco-friendly soap formulation using herbal ingredients that help in cleansing, protecting the skin from microbial infections, and reducing inflammation, thereby promoting overall skin health.
BACKGROUND OF THE INVENTION
References which are cited in the present disclosure are not necessarily prior art and therefore their citation does not constitute an admission that such references are prior art in any jurisdiction. All publications, patents and patent applications herein are incorporated by reference to the same extent as if each individual or patent application was specifically and individually indicated to be incorporated by reference.
The invention is unique because it offers a new herbal soap, prepared by using the Lantana camara leaf extracted in a mild musk-scented soap base with the addition of Turmeric powder. It discusses the emerging issue of skin irritation that arises as the result of chemical loaded commercialised soaps that may contain chemical made detergents, fragrances, and preservatives. Some of these abrasive substances are able to dry out the natural oils found in the skin, alter the pH level of the skin and cause problems like acne, allergies and microbial infections. Contrastingly, the herbal soap is a skin friendly alternative as it is made of plant materials that do not only cleanse the skin but also promote the health of the skin in general due to its bioactive ingredients. A weed like Lantana camara has been highly valued medicinally as its components include flavonoids, triterpene, and essential oils in high quantity. It has displayed antibacterial effect against pathogens such as Staphylococcus aureus and E. coli, anti-fungal activities, and wound healing. It has a calming effect on irritated skin, aids with tissue healing, and goes as far as repelling insects in its natural state. Although these properties, formulation problems and also the fact that it has to mask odor prevents its widespread use in cosmetics. Such difficulties are overcome by inclusion of mild fragrance, musk, into this invention so that the user experiences pleasant experience. Ayurvedic medicine uses turmeric, which is a major source of antimicrobial and anti-inflammatory properties. Its active ingredient, curcumin, fights the acne-causing bacterium, inflammation, discoloration, and balances the overproduction of sebum. It develops an effective herbal synergy with Lantana camara, which can serve to address the causes and the symptoms of typical skin problems. The soap carrier is usually a natural glycerin or herbal dictate that moisturizes the skin and also promotes the even coverage of the active material. Its last product is dermatologically tested and has a skin-safe pH level of 8 and 9 and does not contain any artificial chemicals. The invention provides a clean, natural, and viable alternative that meets the demand of skincare products being gentle and made of herbs.
The inventions in the invention entail the preparation of a herbal, antimicrobial and anti-inflammatory soap comprising Lantana camara leaf extract and turmeric powder to counter the weaknesses of the commercial soaps that contain chemicals that irritate the skin, develop allergies and cause skin infections. The formulation of this soap addresses the usual formulation problems e.g. in terms of stability of ingredients, unsatisfactory masking of odour, and compatibility with the skin. The authors start with the extraction of the bioactive compounds Lantana camara leaves with the help of the Soxhlet apparatus and methanol, and the concentration is done with the help of rotary evaporation. This is the best way to get high yield of antibacterial and anti-inflammatory substances like flavonoids and terpenoids. At the same time, the high-quality turmeric powder, 95 percent of which is the curcumin, is made or provided to be included into the soap matrix.
The bar base is made up with a natural glycerin base or herbal-based creation and melted with a method that utilizes a double boiler process, rather than heating it directly, so that its active substances are not destroyed. Lantana camara extract and turmeric powder are slowly added to the molten soap and stirred continuously so that the process of dispersion is homogenous and bioactive agents can spread evenly in the formula. The strong odor of the extracts will be canceled out by the addition of a natural musk fragrance that will make the extracts much more acceptable by consumers. This mixture is then poured into molds and allowed to rest at room temperature 24 hours. It is then tested on skin (contact sensitivity) as well as dermatological safety (patch testing) and final product prepared. There was no redness, itching, or irritation, which ensured that the skin is compatible. This solution will not only be effective and safe cleansing product, but will utilise underutilised medicinal plants in a sustainable formulation as well. It is a scalable, environmentally friendly cost-effective, and herb drug-free herbal soap that is therapeutic and also will give way to the consumption of natural resources and lessen over reliance on man-made chemicals in the skincare industry.
The skin is one of four major body systems, and keeping that part healthy is quite an issue that is becoming a concern by the day in regards to skin imperfections like acne, bacterial infection and allergic reactions due to skincare products which contain or make up of the chemicals. Most of the commercial soaps have harsh detergents, synthetic additives and artificial fragrances which take away the natural oils on the skin. This does not only weaken the protective barrier of the skin but also poses a greater risk of irritation, dryness, and microbial infections in patients with sensitive or acne prone skin.
To give the user a natural, skin-friendly composed ingredient, the invention uses two extremely strong herbal additives to Lantana camara leaf extract and turmeric powder into a mild smelling musk based soap matrix. The Lantana camara, which is usually considered a harmful weed, has now been scientifically accepted as having the properties of antimicrobial and antifungal as well as properties of recovering wounds. Turmeric- one of the most popular Ayurvedic medicines has anti-inflammatory and antibacterial properties, which relieve the skin, eliminate inflammation, and treat acne-causing bacterium. The product presented in this study will contribute to filling in the research and product gap because the combined use of Lantana camara and turmeric in a cosmetic soap base, combined with a pleasant natural scent is a novelty in the local environment and abroad. Conventional problems like the instability of formulations and bitter odors of the herbs are resolved using regulated procedures of extraction (e.g. methanolic Soxhlet extraction) and powerful odor-masking with musk fragrance.
The soap is prepared by the use of a double boiler technique to introduce efficient herbal substances into a melted foundation, and then the natural solidification will take place. It is dermatologically tested and has no irritative signs during patch tests. The soap has a ph between 8 and 9, which is healthy to the skin as it balances it. Therefore, the presented invention provides an eco-friendly, natural, and harmless option to formulas of chemical soaps, which is in line with modern requirements of having pollution-free skincare.

RESULTS
1. pH Testing
Procedure:
Distilled water was used to make a 1 % aqueous solution of the formulated herbal soap. pH was determined by using standardized pH indicator paper strips.
Result:
The pH of the soap was measured as being around 8.09 to 9.0 appropriate to say that the soap is rather basic. This is optimal PH range giving this product attributes of being able to cleanse effectively without interfering with the skin natural barrier in addition this allows most skin types to be accommodated.
2. Dermatological (Patch) Test
Procedure:
A tiny patch at the back of the hand was wiped clean and a lather of the herbal soap was applied. The spot was marked with the patch and was allowed to sit idle without any disturbances in a period of 20 minutes.
Observations:
• No redness
• No itching
• No swelling or irritation
Conclusion:
The herbal soap proved to be skin safe as no allergic reactions were evidenced in the test subject. This shows that the product can be used regularly and has very low chances of irritation hence can be used by normal to sensitive skin.
ADVANTAGES OF THE INVENTION:
This Manuscript proposes the development of an herb based soap product that can have a set of advantages over other available skincare products which are driven by chemicals. To begin with, it makes use of the natural curative values of Lantana camara and turmeric, the former of which possesses potent antibacterial, antifungal, and anti-inflammatory characteristics, as well as the latter. The invention can easily be incorporated into a mild ill-smelling-soaps base, giving satisfactory results to ordinary skin problems like acne, infections, rashes and inflammation, without the cutting side effects produced by manmade detergents or chemical compounds. As opposed to most of the commercial soaps that take away skin of its natural oils, this soap does not take away the moisture content of the skin but also provides deep cleanliness and safeguards against microbial agents. Moreover, the soap is non-irritating, patch-tested and it is non-irritating and devoid of redness, hence can be recommended to even sensitive skins. Presence of a slight natural fragrance also creates good user experience because they mask the real herbal smell that is eminent by plant extracts. Moreover, it is eco-friendly, sustainable and cost-effective, since most of its botanical ingredients can be obtained with ease as well as its processing avoids complicated technologies, hence, it suits the small-scale and cottage industries. The invention also eliminates wastes and conserves the environment, by simply valorizing little used plants such as Lantana camara, which is usually labelled as invasive weed. On the whole, the invention is consistent with the contemporary consumer trends that have a preference towards personal care products that are natural, safe, and environmentally responsible.
