Description

The utility model relates to cosmetic cleansers, namely, wipes for cleaning brushes from the remnants of cosmetic products used in decorative cosmetics (powder, foundation, lipstick, etc.), for the purpose of further reuse of brushes. Napkins are designed for quick application when cleaning brushes among makeup artists and people who use decorative cosmetics in everyday life.

Makeup products applied by makeup artists and users using brushes have different characteristics, contain different components that differ in composition and properties, which complicates the cleaning process. This problem is very acute for the consumer, a number of inventions show this, in which various devices and devices for cleaning cosmetic brushes are presented, sometimes of rather complicated design: in the form of gloves, gloves with many layers and different cleaning zones (US No. 9,015,895; US No. 9,492,050), pads USD No. 746010, rugs (USD No. 782764; US No. 20120023693), even stand-alone systems (WO No. 2011067677).

It is known that various liquid detergents, for example, soaps, detergents, shampoos and organic solvents of natural or synthetic origin or their compositions, are used to clean and disinfect cosmetic brushes (these are mainly brushes made from natural bristles and fur). Cleansing liquids are first applied to the brush itself or to the tissue of the napkin, to cotton pads, and then with their help further cleaning is performed.

For example, in US patent No. 20110232681 a composition for cleaning cosmetic brushes is patented, in which pink water is used as an emollient (softener), witch hazel is used as an oil remover, triclosan is used as a disinfectant, a clear shampoo is used as a cleansing agent, and as a flavoring agent - rose oil.

US Pat. No. 20160053208 uses goat milk soap with almond, jasmine and lavender oils, as well as coconut oil in a total amount of 2.5 to 9.7% to clean cosmetic brushes.

Since water is used when cleaning with both cleaners, the brushes should dry after washing, and depending on the size of the brush, it takes 6 to 8 hours to dry.

The cosmetics industry also offers a range of liquid cleansers for brushes, these liquids of various compositions, not always indicated, for example, one of them is a liquid cleaner for brushes Lin & Lo (https://linandlo.co.uk/products/.../tools/ brush-cleaner /) based on synthetic alcohols. Its disadvantage is that after constant use, the bristles of the brushes become dry and brittle, after which the cosmetic brushes become unusable. When using this product, its contact with the skin of the hands is inevitable, which makes the skin dry, and inhalation of vapors for a long time is dangerous to health and well-being.

Liquid cleaners are applied (impregnated, sprayed) on a cotton pad or on a paper or cloth, then a brush is cleaned on their surface. In such an option, an uneconomical consumption of the product is detected: cellulose napkins or discs absorb a large amount of the product inside, quickly nap, as a result of which the ability to clean is quickly lost, for which it is necessary to repeat the impregnation procedure. All this increases the time for the cleaning procedure, as well as the amount of consumables and cleaning products.

For a more economical, more convenient and quick cleansing of cosmetic brushes, the most suitable option is wipes pre-impregnated with a liquid cleaner (wet wipes), as for example, this is done for cosmetic wipes to clean the skin of the face (US No. 20140109329, RF No. 2245706). Wet wipes have the advantage that they are ready to use, and the user does not have to separately store and use a wipe and solution suitable for cleaning, as well as waste time preparing. Wet wipes consist of a dry wipe-substrate of the base material and a low viscosity solution, which is impregnated with a wipe.

Some cosmetic companies offer wipes for cleaning brushes, pre-soaked in a cleanser, and their range is quite small, and the composition is often not specified. The material from which they are made (substrate) is most often a non-woven fabric obtained by the aerodynamic method from fibers of synthetic and / or natural origin.

Known wipes for cleaning brushes from cosmetic residues, such as Ecotools wipes in soft packaging ( https://ecotools.com/makeup-brush-cleansing-cloths/.../1310 ). The composition used to soak them is based on water, sodium lauryl glucose carboxylate and fruit extracts. Their disadvantage is manifested in the fact that they do not provide effective cleansing of brushes from cosmetic products, the bristles of brushes are poorly cleaned, the composition does not work against waterproof textures; the material used for napkins is brushed, leaving particles of the cloth on the brush, the fibers of the material “disperse”, which makes the surface of the napkin unsuitable for further use; after processing the cosmetic brush, its pile (bristle) remains wet, because water is based on the cleansing composition and, as a result, the brush dries for a very long time.One napkin is designed for 3-4 brushes.

The closest in technical essence (prototype) to the proposed utility model is the invention according to the application WO No. 2017026909, which is a napkin for cleaning and restorative care of products made of natural fur, made in the form of separate sheets of non-woven material containing at least one layer, the mass of one per square meter of which is at least 80 g., the nonwoven material is made containing at least 70% natural fibers, and is impregnated with a solution containing water and the active substance, which is made as a mixture of extracts from plant material.

Such napkins contain water, therefore, fur or pile after cleaning need additional drying either with a dry napkin or towel, or long-term air drying. Alcohol solutions, as described above, are dried and spoil the bristles of the brushes.

The non-woven fabric for napkins should be strong enough, since it must undergo heavy loads in order to withstand the forces exerted by the user, when the brush is rubbed against it with force, it should not “move apart”. It should be borne in mind that the material is impregnated with a liquid cleaner, and this weakens the bond between the fibers. Non-woven material made from natural and artificial fibers, such as cellulose, viscose is not suitable for such napkins, they are fragile, especially when wet. Wet wipes should have a total surface density of about 25 to about 120 g / m ² . The material (substrate) for wet wipes can have a tensile strength of 1.23 N / cm in the longitudinal direction and at least 0.7 N / cm in the transverse direction. Non-woven polyolefin materials, for example, polyethylene or polypropylene, are suitable for these purposes, they are durable and light, for example, the weight of one square meter of polypropylene is 60-65 g . at high tensile strength, and the strength in the wet state is as high as in the dry.

Accordingly, wet wipes should be packaged so that they do not dry out during long-term storage, and so that they can be easily removed from the packaging, preferably individually. Such systems are known for cosmetic wipes, for example, DE patent No. 102005024647, in which a dispenser container is described where a dry roll of nonwoven material is placed and impregnated with a working solution. The container is closed with a lid that contains a hole for removing tissue. The end of the roll is pulled through the opening of the lid, so that some of the napkin protrudes from the opening. After removal, it is possible to separate the tissue according to the provided perforation so that the remainder of the next tissue protrudes from the hole.

The technical result of using the utility model is to accelerate the cleaning process due to faster one-stage cleaning of each brush, increasing the efficiency of processing brushes for makeup, which is achieved:

• an increase in qualitative and quantitative indicators when using one napkin (each napkin should, if possible, clean as many brushes as possible from 15 to 20 pieces, preserving its properties for as long as possible),

• providing faster drying time for bristles,

• increase the shelf life of the quality of brushes,

• improvement of safety of use,

• improving simplicity and ease of use,

• greater efficiency.

The technical result is achieved due to the fact that a wet towel for express cleaning of cosmetic brushes, including a layered base of non-woven material and liquid impregnation, contains polypropylene material as a non-woven material, and isododecane as a liquid impregnation.

In addition, to protect against drying out and ease of use, the napkin is rolled up and placed in a tube of 50 or 100 pieces each.

A series of experiments were conducted to prove the improved quality of the wipes.

Since detergents containing water increase the drying process of brushes, which contradicts the concept of this utility model, therefore, aqueous solutions for impregnation were not considered.

Since alcohol overdries the pile and worsens its condition over time (the pile of the hands becomes brittle), it was decided to replace the alcohol-containing organic substance with non-alcoholic organic matter that has good volatile properties, which would ensure quick drying of the pile. Isododecane, a light emollient that perfectly dissolves all types of cosmetics (fatty, dry pigments, waterproof and helium products), was chosen as such a substance. It is characterized as a safe substance, non-carcinogenic, safe for pregnant women, non-immunotoxic, which allows many world cosmetics manufacturers to use it in expensive creams and shampoos. Isododecane easily evaporates from the surface of the bristles and does not spoil them.

The possibility of combining isododecane with other organic substances, for example, hexylene glycol (Hexylene Glycol), a diatomic heavy alcohol that also dissolves cosmetic products well, is widely used in cosmetics, and is found in combination with other components in brushes to cleanse. With isododecane, it has a different polarity, and therefore, when combined, separation was observed, both in the liquid state and on the surface of the napkin. When an emulsifier was added to the mixture of these components to eliminate delamination, the consistency of the mixture became thick, creamy, and the time to complete drying of the pile increased, the pile became sticky, rinsing with water was required, which contradicts our concept of express cleansing.

The possibility of adding additional components to the impregnation of wipes with properties similar to isododecane (isopropyl stearate, isopropyl palmitate, dimethicone) was considered, but since they all had a recommended safe input percentage of not more than 15%, they did not show improvement in cleaning efficiency compared to pure isododecane .

It was experimentally found that isododecane itself fully meets the needs of use in its pure form, while its consumption for the same number of brushes with the same degree of pollution was much more economical than that of its mixtures with other emollients, and therefore it was decided to take isododecane as the main only active substance.

The choice of material for napkins.

The following material options are considered: woven, cellulose-based, non-woven.

They chose non-woven material, since woven materials, having strength advantages, have a sufficiently large specific gravity and large volume, and also do not withstand competition in cost. Pack them in a tube of 100 pcs. practically not possible, because because of their density and volume, they do not fit in a standard tube.

Cellulose napkins lose their strength when wet, when wet, which does not meet the requirements for napkins.

Synthetic non-woven material is not lint, has a fairly low production cost and, in addition, it is perfectly impregnated with liquid, has high capillary properties, preventing the liquid from evaporating for a long time. Non-woven polypropylene material showed the best result.

Testing revealed the optimal size of the wipes - 130 mm x 170 mm, which will be enough to clean 15-20 brushes, i.e. average number of brushes in a consumer set,

Also, with the help of experiments, the optimal amount of impregnation for one napkin to clean a set of brushes from 15-20 positions - only 3.5 ml was revealed. isododecane for the manufacture of one wet towel (20% by weight of impregnation with respect to 100% by weight of the towel), while for the same number of brushes using liquid cleaners (the liquid is poured onto the towel), an average of 15 ml is used. facilities.

With a smaller amount of impregnation taken (3.5 ml of isododecane), the wipes are not sufficiently moistened, with a larger one, on the contrary, the impregnation oozes from the napkin and drains when using it.

The time spent on brush processing with such a napkin is markedly reduced. Firstly, due to the fact that the napkin is a finished product, it is not necessary to prepare it, fill it with a cleaner, and secondly, due to the fact that it remains wet for a long time, and it can be cleaned qualitatively from 15 to 20 brushes at a time . This becomes possible due to the combination of the properties of isododecane with the properties of a non-woven polypropylene fiber: the impregnation in it does not evaporate for a long time, since it fills the small capillaries that are characteristic of polypropylene material. Isododecane is well retained and longer volatilizes from the inside of the fibers and capillaries, which allows you to clean a fairly large number of brushes with one towel. This just helps save time on cleaning them. Thus, a damp cloth made of polypropylene fiber soaked in isododecane is an economical and ergonomic cleanser for makeup brushes.

Wet wipes should be hermetically sealed to prevent drying out. Variants of single packaging, soft packaging of a stack of napkins of 50 pieces and packaging in a roll in a tube of 50 or 100 pieces were considered. The latter option turned out to be most preferable, since it takes much less time to extract from the tube than to remove it from soft packs, and the extraction itself is much simpler. This is also an important factor in saving time. In addition, napkins in a tube retain their qualities much longer than in a pile in soft packaging, and soft packaging with a sealed dispenser lid loses in value to napkins in a tube, as does the packaging of each napkin individually (single).

The impregnation of napkins is as follows: place a roll of napkins in the amount of 50 or 100 pcs. into a tube and pour them 350 ml of isododecane. The impregnation is perfectly distributed throughout the roll with napkins, after which the neck of the tube is hermetically sealed and stored until use. After opening the tube, a special tight cover is put on the throat opening.

Test result of wet wipes made of polypropylene with isododecane impregnation:

The number of brushes cleaned with 1 tube (50 napkins) is approximately 2000 pcs., Which is 25 times more than when brushing with Ecotools napkins (50 pcs in soft packaging closed with an adhesive cover).

Given the significant savings in the time of using a wet wipe, the low cost of producing non-woven polypropylene material and a high degree of isododecane cleaning, the final product, a napkin for express cleaning of cosmetic brushes, will compete in the market of high-quality cosmetic products at an affordable price category.

Thus, a wet wipe for express cleaning of cosmetic brushes made of non-woven polypropylene material, in combination with isododecane impregnation, in the amount of 20% impregnation relative to the weight of the wipe, made in the form of a roll placed in an airtight tube, is most fully consistent with the claimed technical result.
