Functional Exfoliating Soap

Description

/ 4 Functional Exfoliating Soap Field of Invention

[001] The present invention belongs to the technical field of cosmetics and personal care, more specifically to the production of exfoliating soaps. It relates to the use of industrial waste, particularly basalt rock powder, as a main ingredient in soaps intended for the care and exfoliation of human skin. The invention can also be applied to the environmental sustainability sector, since it uses a waste product from the stone industry (crushed stone production), providing a solution for reducing the environmental impact generated by this material. Fundamentals of the Invention

[002] The state of the art related to exfoliating soaps already includes a wide range of products that use synthetic or natural ingredients to promote the removal of dead skin cells. Typically, these soaps use components such as plastic microbeads, mineral salts, fruit peels, or other exfoliating ingredients.

[003] However, these products face some limitations. The plastic ingredients used in many exfoliating soaps contribute to increased pollution in oceans and ecosystems, as well as generating a significant environmental liability. In addition, most exfoliating soaps use ingredients that do not add value to industrial waste, missing an opportunity to promote sustainability.

[004] The basalt rock powder used in the present invention, a residue from the stone industry (crushed stone production), is an underutilized material that is frequently disposed of improperly in the environment. The technical problem is not Petition 870240111422, dated 12 / 31 / 2024, page 10 / 19 / 4 resolved is the lack of sustainable use of this material in commercial products, especially in cosmetics.

[005] The proposed invention solves this problem by transforming basalt rock residue into an exfoliating ingredient for soaps, with the added benefit of providing an environmental solution for the disposal of this material. Furthermore, the invention offers a product with gentle exfoliating properties and without the environmental impacts associated with synthetic ingredients. Brief Description of the Drawings

[006] For better understanding, the invention has the following drawings listed below: Figure 1 shows the soap prototype; Figure 2 shows the CAM-TB Test, demonstrating non-irritability; Figure 3 shows the abrasiveness test of the soap. Description of the Invention

[007] The invention describes an exfoliating soap, the base of which is mainly composed of vegetable oil and glycerin, to which basalt rock powder is added. The soap has a creamy texture which, when applied to the skin, exfoliates without causing damage or injury. The main innovation lies in the use of basalt rock powder, a residue from the manufacture of crushed stone, which has a particle size of up to 1 mm and is rich in mineral oxides such as iron, silicon, calcium, phosphorus, aluminum, potassium, titanium and magnesium.

[008] The soap is produced as follows: 1. Melting the vegetable glycerin base: 85g of glycerin base specifically for soaps are melted at 60°C. Petition 870240111422, dated 12 / 31 / 2024, page 11 / 19 / 4 2. Addition of basalt rock powder: After the base is completely melted, add 85g of basalt rock powder and mix until the powder is completely incorporated. 3. Molding and cooling: The mixture is poured into specific molds and refrigerated at 2°C for 30 minutes to solidify.

[009] This process results in a functional soap that combines the exfoliating properties of rock powder with the benefits of a glycerin base. The soap is easy to apply and use, providing a gentle and effective skin exfoliation experience.

[010] In addition to the use of basalt rock powder, the soap formula may also include other cosmetic ingredients, such as propylene glycol, dipropylene glycol, sodium lauryl ether sulfate, ethyl alcohol, tetrasodium EDTA and fragrances that provide additional sensory and preservation characteristics to the product. Examples of Implementations of the Invention

[011] The preferred embodiment of the invention is the formulation of an exfoliating soap that uses between 2% and 4% basalt rock powder relative to the total weight of the soap, as described. This proportion was determined based on laboratory tests that evaluated the exfoliation efficacy and the safety of the product.

[012] The results of comparative tests between different concentrations of rock powder and different types of glycerin bases demonstrated that a concentration of 4% basaltic rock powder offers effective exfoliation without compromising the safety of the product, which was tested in toxicity and irritation assays.

[013] Example of a preferred formulation for 100g of soap: • 85g vegetable glycerin base • 85g basalt rock powder • 3g propylene glycol • 1g sodium lauryl ether sulfate • Fragrance (variable quantity, according to need) Petition 870240111422, dated 12 / 31 / 2024, page 12 / 19 / 4

[014] This soap has been laboratory tested to prove that it does not present toxicity or irritating effects on the skin. The tests performed were: 1. Lactate dehydrogenase test (in vitro, using Tenebrio molitor). 2. Chorioallantoic membrane irritation test (CAM-TB) in fertilized chicken eggs.

[015] Both tests proved that the product is non-irritating, meeting safety standards for use in cosmetics.

[016] The proposed invention offers an innovative solution for the sustainable use of industrial waste, by transforming basalt rock powder into an exfoliating ingredient for soaps. The developed soap is efficient, environmentally friendly and low-cost, representing a sustainable alternative in a cosmetic market that is increasingly demanding in terms of reducing environmental impact.
