Abstract

The present invention relates to solid cosmetic formulations, in the form of topical tablets, containing active agents intended for various functions, such as skin hydration, treatment and prevention of blemishes, sun protection, makeup, and hygiene products such as shampoos and soaps. The cosmetic tablets were obtained directly, although they could be obtained by other methods. Being anhydrous, they aim to reduce water consumption in the production process. This favors greater stability, less possibility of contamination, and greater efficacy of the active ingredient. Their use involves the addition of water for disintegration and to achieve the concentration indicated on the product label.

Description

FIELD OF THE INVENTION [001] The present invention relates to solid cosmetic formulations in tablet form, which may comprise active agents for a wide variety of purposes, such as skin hydration, prevention of blemishes, oil control, and evening out skin tone. The present invention also relates to solid cosmetic formulations in tablet form, comprising pigments for obtaining makeup, sunscreen, and cosmetics for facial and hair cleansing such as soaps and shampoos. [002] The invention also includes cosmetic compositions, obtained after the addition of water for use. Such compositions can be used for a wide variety of purposes, such as skin hydration and treatment, as well as for makeup, sun protection, cosmetics for skin and hair care and cleansing. BACKGROUND OF THE INVENTION [003] The search for a more conscious and responsible beauty has been growing exponentially, driving the cosmetics industry towards Clean Beauty. This line of action focuses on the development of innovative formulations that prioritize the health of the consumer and the planet. [004] Traditional cosmetic product manufacturing uses considerable amounts of water, both in the product composition and in subsequent stages of the production process, such as cleaning and maintenance of machinery, among others. It is known that industrial production is responsible for 20% of global water withdrawals, mainly for energy production from cooling/heating processes. [005] In the cosmetics industry, in most cases, the amount of water in the composition of products is greater than that of other ingredients, representing more than 2/3 of the volume of a formula, with a cream containing 60 to 80% water, a lotion up to 90%, and a shower gel or shampoo up to 95% water. [006] In the cosmetics industry, water is normally used as a solvent or vehicle for incorporating active ingredients and as an element to create pharmaceutical forms as well as emulsions in which oily and aqueous components are combined to produce creams and lotions. [007] In this context, reducing water consumption is understood as a central objective for companies concerned with sustainability plans, and is also becoming an increasingly important point of attention for a large part of consumers. [008] The large-scale use of water motivates the development of products that use little or no water in their production and/or composition, the so-called waterless cosmetics. These products refer to all types of cosmetics developed to reduce or eliminate the water used as an ingredient, in the manufacture or necessary to use the product, and are commonly produced by compacting the ingredients into a solid body, the most common products being shampoos, conditioners, soaps and, more recently, toothpastes. [009] Waterless cosmetic production processes have the potential to prevent microbial contamination and reduce the likelihood of hydrolysis and oxidation reactions. Furthermore, they have a longer shelf life and require fewer preservatives. [010] Among other advantages, waterless formulas provide products with smaller volume and size, which can be packaged in smaller and lighter packaging, usually made of biodegradable paper or cardboard, or recyclable materials, avoiding the use of plastic and reducing weight and transport space, requiring less fuel and energy consumption, decreasing CO2 emissions, and leading to a smaller overall carbon footprint. In addition, these products are convenient to take on trips, being possible to transport them in airplane cabins. [011] Alternatives that are commonly used in the development of waterless products are products that do not need to be pre-emulsified, for example shampoos and conditioners in bar form that need a small amount of water to emulsify. Dry shampoos and conditioners are also a growing alternative, being quite useful between traditional washes. [012] Document CN109662898 describes a solid skin care product and a method for preparing it that overcomes the technical problems associated with products that are conventionally presented in the form of creams/liquids, such as the possibility of contamination by impurities and/or bacteria. [013] The product described in this document comprises a substrate, an emollient (such as seed oil), an emulsifier and a functional active ingredient, and a matrix component, wherein the matrix component is a water-soluble molecule with a molecular weight between 0.3 million and 1 million. The emollients may be polar or non-polar representing approximately 0.1% by weight to 30% by weight, in addition to various oil-in-water (O/W) emulsifiers in the range of 0.1% by weight to 20% by weight. [014] Ascorbic acid and niacinamide are specifically mentioned as active agents, and it is described that to use the product, an adequate amount of water must be dripped onto the solid product, which will disintegrate rapidly, releasing a large amount of active substance that can be absorbed through the skin. It is also described that
