Toothpaste in tablet form having a water-free formulation with essential oils as antimicrobial active ingredients

Abstract

The present invention relates to toothpaste in the form of a compressed powder that has a water-free chemical composition and is formulated with natural inputs, which have an antimicrobial role and are not harmful to health when used. Some of the natural inputs in the formulation are essential oils, preferably from Eucalyptus globulus (Eucalyptus), Minthostachys mollis (Muña) and Mentha piperita (Mint). Furthermore, the structure of the toothpaste contains biodegradable inputs. The process for manufacturing the product consists of dry granulation, which consists of mixing the liquid inputs with the solids, followed by a drying and screening process to finally make a mixture of all the ingredients, and to continue with compression in a conventional tablet press, and finally packaging.

Description

[0001] Water-free tablet-shaped toothpaste formulated with essential oils as antimicrobial active ingredients.

[0002] TECHNICAL FIELD

[0003] The present invention is developed in the technical field of personal care and hygiene products, specifically in oral hygiene products.

[0004] BACKGROUND OF THE INVENTION

[0005] Many oral hygiene products are toxic due to their composition, as they contain sulfates, fluoride, thclosan, and other chemical compounds that cause health problems for many users.

[0006] The state of the art of chewable tablets with chemical components is known, whose main characteristic is being portable and easy to use, but these products have chemical components within their formulation and these inputs fall into questions, due to their toxicity to humans, one of the questioned ingredients is sodium lauryl sulfate, used as a detergent and parabens, used as preservatives, which also have reports of toxicity and are prohibited in some countries.

[0007] For example, in the Asian market, there are tablet toothpastes made entirely of chemical components whose main characteristic is their slow foam release. However, to achieve this slow release, it is necessary to use chemical components such as carrageenan, a thickener derived from seaweed, which can cause intestinal problems and even cancer.

[0008] Also known in the state of the art is US8728446B2 of a toothpaste in tablets for dental hygiene that contains chemical inputs combined with natural extracts, in whose formulation there is also the use of chemical components questioned for their toxicity to the consumer.

[0009] Additionally, toothpaste tubes take 500 years to completely biodegrade, meaning every tube you've ever used could still be sitting in a big hole in the ground. Many oral hygiene products suffer from contamination, as the ingredients used in the manufacture of conventional toothpaste, such as fluoride, are extremely toxic when they reach the marine environment.

[0010] On the other hand, water is the so-called "BLUE GOLD," and its scarcity will be the world's problem by 2050. By 2025, two-thirds of the world's population will be living in conditions stressed by the lack of water. Today, 2 billion people suffer from water scarcity. Nineteen percent of the world's water, from various sources, is used by industry, and the personal care industry uses water as the main component of its formulations.

[0011] The review of the state of the art reflects the urgent need to reduce toxic components in oral care product formulations, such as toothpastes, liquid mouthwashes, and others, due to the potential harm they cause to consumers' health.

[0012] DESCRIPTION OF THE INVENTION

[0013] The present invention addresses this problem by providing a dentifrice in the form of a compressed powder containing no water in its chemical composition. It is formulated with ingredients of natural origin and contains natural essential oils as its antimicrobial components. The formulation comprises an abrasive agent that removes dirt, cleans teeth, and removes residue from the adherent layers of the bacterial film without wearing down the dentin of the teeth. It also includes a thickening agent. When the tablet toothpaste dissolves in the mouth, this ingredient or agent allows it to achieve a viscosity similar to that of conventional toothpaste. Microcrystalline cellulose and cellulose derivatives such as sodium carboxymethylcellulose and sodium carboxymethylhydroxyethylcellulose are examples of thickening agents.

[0014] A disintegrating agent is included, which provides optimal dissolution and disintegration in the mouth. Also included is a tableting vehicle, which is selected based on its compatibility with the other ingredients, particularly the abrasive agent, and also the desired product characteristics, such as size, hardness, and disintegration time. The tableting vehicle is present at an effective level, particularly in the range of 20 percent to about 80 percent weight / weight, more preferably from about 38 percent to 65 percent weight / weight.

[0015] The toothpaste tablet is produced using the direct compression technique, which involves several processes, including: powder mixing, moisture measurement, and finally compression in a single-punch tablet press.

[0016] The present formulation proposes a solution that covers the following needs: the urgent need to avoid using water in the formulations of oral care products, such as toothpastes, mouthwashes, among others, since for these types of products, water is the main ingredient in their formulations and the one with the highest percentage. Likewise, unlike the prior art, the present invention contains ingredients of natural origin that do not cause harm to the health of consumers and, additionally, the toothpaste formulation has biodegradable ingredients. BRIEF DESCRIPTION OF THE FIGURES

[0017] No figures are presented.

[0018] PREFERRED EMBODIMENTS OF THE INVENTION

[0019] The toothpaste in the form of a compressed powder that does not contain water in its chemical composition, formulated with ingredients of natural origin and whose antimicrobial components are natural essential oils, includes the following components in its formulation

[0020] - Sodium lauryl sulfoacetate as a powdered surfactant at a concentration of 10% to 15% w / w. This ingredient's function is to cleanse, form foam, and act as a natural detergent. It is activated upon contact with water and brushing, producing a creamy foam. The surfactant component must not be hydrated, so it must be stored in an environment with a humidity of 65% to 80%.

[0021] - A microcrystalline cellulose ranging from 20% to 80% w / w, more preferably from 38% to 60% w / w. It binds the formulation's ingredients, contributes to the tablet compaction process, and facilitates rapid tablet disintegration upon contact with water and when brushing with teeth.

[0022] - Three antimicrobial agents of natural origin, essential oils preferably from aromatic plants Eucalyptus globulus (Eucalyptus), Minthostachys mollis (Muña) and Mentha piperita (Peppermint) obtained by any physical steam extraction method, ranging between 0.5 and 2% w / w within the formulation, these oils, a product of homogenization with the powders in the formula, coat the surface of the particles facilitating the adhesion of the powder particles and maintaining the structure of the tablet; it gives the formulation the necessary oiliness without affecting foam formation.

[0023] - Sodium bicarbonate as an alkalizing agent, a biodegradable input whose function is to alkalize the medium for the best performance of surfactants in a concentration between 3 and 8% w / w

[0024] - Stevia rebaudiana as a natural sweetener that gives a traditional toothpaste flavor, in a proportion between 0.5 and 1.0% w / w - An essence and natural colorants that can give smell and color to the toothpaste in tablet, in percentages from 0.1% to 5.0% w / w.

[0025] The formula, with all its ingredients, is mixed at a temperature between 21 and 28 degrees Celsius, sieved to ensure good dispersion and control the homogeneity of the powders, and compacted by applying a compression / compaction force and time. The pressure and compaction time depend on the resulting structure of the mixture; these are adjustable parameters. The pH of the mixture must be between 6.5 and 7.5.
