RU186725U1 - Roll of wet wipes for cleaning cosmetic brushes - Google Patents

Abstract

The utility model is aimed at accelerating the process of cleaning cosmetic brushes from the remnants of cosmetic products used in decorative cosmetics. Napkins are designed for quick use when cleaning brushes among makeup artists and people who use decorative cosmetics in everyday life.

The technical result obtained by using the utility model is to improve the consumer qualities of a roll of napkins for cleaning brushes from cosmetics due to the fact that the process of complete cleaning is achieved in one stage, and the time spent on processing brushes with one such napkin is significantly reduced. The napkin roll remains wet for a long time, and one napkin can be cleaned qualitatively at a time from 15 to 20 brushes. To protect against drying out and ease of use, wet wipes are folded into a roll, unwound from the center, and placed in a tube with a hole in the lid of 50 or 100 pieces each.

The technical result is achieved due to the fact that the roll of wet wipes for cleaning cosmetic brushes, including a layered base of non-woven material, wrapped in a roll, and liquid impregnation, contains polypropylene as a non-woven material, and isododecane as a liquid impregnation. The combination of the properties of the isododecane emollient with the properties of the non-woven polypropylene fiber for a long time keeps this impregnation in the capillaries, as well as wrapping the napkins in a roll and placing the latter in the package provide the claimed effect. 3 ill.

Description

The utility model relates to means for cleaning cosmetic brushes from cosmetic residues in beauty salons or at home.

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.

The cosmetics industry also offers a range of liquid cleansers for brushes of various compositions, for example, Lin & Lo synthetic alcohol based liquid cleanser (https://linandlo.co.uk/products/.../tools/brush-cleaner/). 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, 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.

Wet disinfectant wipes are currently produced and sold in various forms: in single-use packages, one napkin or in stacks of several napkins, as well as in rolls placed in special dispenser tubes or wrapped in a waterproof membrane. Such wipes typically contain an antimicrobial preparation and / or alcohol as a disinfecting agent (s). The alcohol component, usually at a concentration of 70% or more, also serves as a drying agent. The high concentration of alcohol used causes the problem of overdrying the cleaned object. Another problem is the flammability of such drugs.

The closest in technical essence (prototype) to the proposed utility model is the invention according to US patent No. 8367568, IPC B32B 5/02, B32B 27/04, B32B 27/12, in which wipes for cosmetic purposes from non-woven fibrous material are packaged in a roll separated by perforation of the sheets in a moisture-proof container containing any number of sheets per roll, impregnated with a moisturizing composition applied to the wipes. The roll may be heartless, hollow inside or solid. It is proposed that the roll rollers of this patent be manufactured using roll layers from well-known companies, for example, SRP Industry, Inc. from San Jose, California, USA or Shimizu Manufacturing of Japan, or as rolls described in US Pat. Nos. 4,667,890 (IPC B65H 18/16, B65H 19/267, B65H 19/30) and No. 5540332 (IPC A47K 10 / 421, B65H 83/08, A47K 10/32).

The technical result achieved by using the utility model consists in improving the quality of brush cleaning by increasing the retention of liquid impregnation in the layered structure of polypropylene formed by small capillaries, and the use of quickly absorbing synthetic isododecane emollient promotes better removal of cosmetics from brushes.

The technical result is achieved due to the fact that in a roll of napkins, for cleaning cosmetic brushes made in the form of a tape of a layered non-woven material, equipped with perforations, impregnated with liquid impregnation and wrapped in a roll, polypropylene is used as non-woven material, and as liquid impregnation isododecane

The non-woven fabric for napkins should be strong enough, since it must undergo heavy loads to withstand the forces exerted by the user, when the brush is rubbed against it with force, it should not "disperse". 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 strong and light, for example, the weight of one square meter of polypropylene is 60-65 g with high tensile strength, and the wet strength is as high as in the dry.

The following materials were investigated: woven, cellulose-based, as well as non-woven. As a result of the tests, they came to the conclusion: to use 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 together for 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,

To protect against drying out and ease of use, the napkin is rolled up and placed in a tube (50-100 pieces each).

To find the best option in order to obtain improved quality wipes, a series of experiments was conducted.

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. With isododecane, hexylene glycol has a different polarity, in connection with which, when combined, separation was observed, both in the liquid state and on the surface of the wipe. 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.

To impregnate napkins, they need to be arranged, a roll is best for this. To protect unused napkins from contamination and to prevent their premature drying, the roll must be placed in a dispenser for storing and dispensing napkins.

Making napkins.

Napkins are made in the form of a tape 130 mm wide of non-woven propylene fiber with separation from one another, for example, by punching perforations every 170 mm, thus obtaining one napkin 130 x 170 mm ^{2 in} size. To select a roll for napkins, we considered options for rolls: heartless, hollow inside, solid. In RF patent 2408522 (IPC B65H 18/28, B65H 19/22) a roll of tape material without a tube is described as being hollow from the inside. The roll comprises a first inner part of the tape material that forms the inner core of the roll, and a second outer part of the tape material that is wound on the inner core of the roll. Between the first inner part forming the inner core and the second outer part wound on the inner core, there is a border that facilitates the extension of the first and second parts of the tape material relative to each other. The first inner part and the second outer part of the tape material form two independent usable products in the form of rolls of tape material. Thus, the roll can be unwound, both from the inside and the outside, while the tapes are not interwoven. Such a roll is versatile and convenient, allows both central and peripheral feeding of napkins, but is difficult to manufacture and requires the introduction of a special additional device for the rewinder when winding each roll, to create a boundary between the first and second parts of the tape material, which complicates the winding process and leads to an increase in the cost of the roll. Solid coreless rolls, the manufacture of which is described in the patent literature, for example, RF patent 2152752 (IPC А47К 10/16), are not entirely suitable for our napkins, since solid rolls are unwound from the periphery, and not from the center.

Napkins according to this utility model are supposed to be placed in a dispenser tube with a central outlet with a hole in the lid for ease of removal, for example, as in RF patent 2435512 (IPC A47K 10/36, therefore it is necessary to use a hollow roll from the inside that allows feeding tape from the center The delivery of the tape from the center of the roll has several advantages compared to unwinding it from the periphery of the roll, since the roll in the dispenser can remain stationary, and the only thing to be displaced in this case is pullable Tape napkins.

The essence of the utility model is illustrated by drawings (Fig. 1-3).

 Figure 1 - view of a hollow unwound from the center of the roll (roll Central unwinding); Figure 2 - view of the roll placed in the tube during the impregnation process; Figure 3 - View of the roll in the tube ready for use.

The impregnation process is as follows:

A roll of central unwinding napkins (Figure 1) is placed in a plastic dispenser tube with a hole in the lid, where the calculated amount of isododecane emollient is poured (Figure 2), The tube is closed with a lid with an opening through which the end of the napkin tape is pulled (Figure 3) ) Prior to use, the tube is sealed to prevent the emollient from drying out during storage.

Using experiments, we found the optimal amount of impregnation for one napkin to clean a set of brushes from 15-20 positions - this is 3.5 ml. isododecane for the manufacture of one wet towel (20% of the mass. impregnation in relation to 100% of the mass. Napkins). 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 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 with the calculated amount of isododecane: 175 ml per 50 napkins, 350 ml per 100 napkins. 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.

During use, the packaging is opened and, starting from the central part of the roll, the tape is pulled in the direction of the longitudinal axis of the roll, perpendicular to the plane of its winding, then the cloth is torn off by perforation.

Due to the fact that the wipes remain wet for a long time, and each of them can be cleaned qualitatively at a time from 15 to 20 brushes, this helps to save time for cleaning them with high quality. This becomes possible due to the favorable combination of the absorbing properties of isododecane with the properties of non-woven polypropylene fiber: the impregnation in it does not evaporate for a long time, since it fills the small capillaries characteristic of the polypropylene material. Isododecane is well retained and longer volatilizes from the inside of the fibers and capillaries, which makes it possible to qualitatively clean a fairly large number of brushes with a single wipe (15-20). Thus, a wet cloth made of polypropylene fiber in a roll soaked in isododecane is an economical and ergonomic tool for cleaning makeup brushes.

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 cleansing of cosmetic brushes will be a worthy competition in the market of high-quality cosmetic products at an affordable price category.

Thus, a roll of wet wipes for express cleansing 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 wipes, placed in an airtight tube, is most fully consistent with the stated technical result.
