CONTAINER FOR COSMETIC PRODUCTS

Description

Object of the invention

[0001] The present invention relates to a container for cosmetic products, which is formed from a composition comprising wax or paraffin for the most part.

Background of the invention

[0002] Waxes and paraffins have a wide variety of uses, such as, for example, in the manufacture of candles, as a sealant for paper or food products, for the extraction of perfumes from flowers or as a base for chewing gum.

[0003] Candles are one of the main applications of wax and there are different ways to prepare them, depending on the type of candle that is made. Thus, there are waxes to fill, where it is poured melted into the final container; waxes for a pressed method, where the candle is pressed into the desired shape; candles manufactured by a extrusion method; by an immersion method; by a stretching method, where layers of wax are added until the required thickness is obtained; and by a casting method, for which molds are needed, which is the most difficult method of making candles.

[0004] Waxes and wax mixtures are widely used in the paper industry, for example in the production of cardboard and technical paper, flexible food containers, paper cups and disposable plates, etc.

[0005] Said waxes contribute to the resistance to water and humidity, offer shine, torsion effect, protection from grease and odors, etc. and they are used for impregnating, covering, coating, laminating, and as adhesives.

[0006] Waxes are also used in cosmetics due to their softening and protective properties; they are resistant to oxidation, humidity, and microbiological degradation. They are also used as emulsifiers and co-emulsifiers, and to provide stability and sensoriality to personal hygiene and beauty products. Waxes increase the viscosity and consistency of the mixtures in which they are included. In cosmetics they are also used as a method of hair removal.

[0007] Waxes are also used in agriculture, the rubber industry, and the textile industry.

[0008] On the other hand, the containers are usually made of glass, metal or plastic, since they must have the possibility of containing the product, they must preserve and protect the content, it cannot be mixed with the content of the container itself, that is, it must not interact with the product contained and kept inert, it must be hermetic and prevent leaks, it must present resistance, adaptation to automatic factory production and the cost of production and its sale price must be adequate.

[0009] Therefore, although wax is a product widely used in the industry, it is not used in the manufacture of containers because it is considered that it would not meet the requirements for a container.

Disclosure of the invention

[0010] Therefore, an object of the present invention is to provide a container for cosmetic products formed from a composition comprising wax or paraffin for the most part and meeting the requirements of conventional containers made of glass, plastic, or metal.

[0011] With the container for cosmetic products of the invention said disadvantages are solved, presenting other advantages that will be described below.

[0012] The container for cosmetic products according to the present invention is described in claim 1, and the dependent claims include additional features that are optional.

[0013] In particular, the container for cosmetic products is formed from a composition that comprises one or more waxes, preferably of vegetable origin, or paraffin, preferably of mineral origin, in a percentage by weight between 70% and 100%, for example, between 90% and 100%.

[0014] In addition, the container composition may comprise different first and second waxes, wherein the composition comprises the first wax in a percentage by weight between 50% and 75%, and the composition comprises the second wax in a percentage by weight between 25% and 50%.

[0015] If desired, the container composition may also comprise one or more additives, in a percentage by weight between 2% and 10%.

[0016] According to alternative embodiments, the container composition comprises 98% by weight of one or more waxes, or paraffin, and 2% of one or more additives, the container composition comprises 95% by weight of one or more waxes, or paraffin, and 5% of one or more additives, or the container composition comprises 90% by weight of one or more waxes, or paraffin, and 10% of one or more additives.

[0017] According to preferred embodiments, the wax or waxes are chosen from the following waxes: carnauba wax, candelilla wax, sunflower wax, cassava wax, and/or microcrystalline wax, and the one or more additives are chosen from the following: glyceryl behenate, glyceryl stearate, stearic acid, glycerin, shea butter, grapeseed oil, jojoba esters, coco caprylate/caprate, cocoa butter and/or caprylic capric triglycerides.

[0018] Therefore, a wax container is achieved that is not malleable below 50 °C, whose melting point is equal to or greater than 60 °C, and that crystallizes, achieving a smooth and seamless surface.

[0019] In addition, the container according to the present invention does not react or mix with the material contained therein, it is hermetic and allows the contents to be correctly preserved, and it is also resistant to be able to store it for at least 30 months.
