Description

A cleaning composition comprising alkanediol or ethylhexylglycerin {Cleaner composition comprising alkanediol or ethylhexylglycerine}

The present invention relates to a cleaning composition comprising alkanediol and/or ethylhexyl glycerin as main components of a detergent, and more particularly, to a cleaning ability of alkanediol and/or ethylhexyl glycerin used as preservatives. Even if it contains alkanediol and/or ethylhexylglycerin and water as the main ingredients of the detergent, it maintains the characteristics of the detergent, has less irritation to the skin, has antibacterial and antiseptic properties, and leaves no residue. it's about

Conventionally, in detergents based on surfactants, there are cases where there is a need for appropriate thickening in consideration of the dispersion stability of the insoluble solids contained therein, although there is convenience in use by consumers. As a conventional thickening method, a method of making viscosity by mixing different types of surfactants (eg, amphoteric surfactant and anionic surfactant) to form a complex, and adding an inorganic salt to increase the viscosity by aggregation of micelles There are three methods: a method of making it, and a method of using a thickener.

In the case of a method using a combination of different types of surfactants, the surfactant content tends to be high. In addition, there is also the point that it is very difficult to thicken depending on the type of surfactant used as the subject. As such an example, the detergent composition which has as a main subject polyoxyethylene sulfosuccinate disodium lauryl, cocoyl-L-glutamic acid monotriethanolamine, polyoxyethylene lauryl ether acetate sodium, cocamidepropyl betaine, etc. is mentioned. Many of these difficult-viscosity surfactants and their formulations are generally considered to be hypoallergenic and are expected to be used in various applications, but even when combined with other surfactants, it is often difficult to achieve a desired viscosity.

In the method of thickening by mixing an inorganic salt, sodium chloride, sodium sulfate, etc. are mainly used as an inorganic salt. However, these inorganic salts have a low thickening effect with respect to the added amount, require a large amount of addition to adjust the desired viscosity, and have safety problems such as feeling of irritation.

In the method of focusing by using a thickener, a nonionic surfactant or a high molecular weight thickener is often used. As the nonionic surfactant, polyoxyethylene alkyl ether, palm oil fatty acid diethanolamide, polyethylene glycol distearic acid ester, and the like are used. However, these nonionic surfactants require a large amount of addition, and have problems such as poor feel, poor low-temperature stability, and poor solubility.

On the other hand, as the polymer-based thickener, hydroxymethyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose, cationized cellulose, polyvinyl alcohol, sodium polyacrylate, starch, xanthan gum, etc. are used. In the method using a high molecular weight thickener, it is possible to obtain a viscous detergent composition at a relatively low concentration, and has high skin stability, and is easy to add to a hypoallergenic detergent composition. However, a high molecular weight thickener often has a poor thickening effect in detergents containing a water-soluble ionic substance in combination. Xanthan gum has a thickening effect even in the presence of water-soluble ionic substances, and it is possible to thicken a hypoallergenic cleaning composition that is considered to be difficult to thicken, but it is not particularly slippery and a sufficient amount is formulated to ensure stability. There was a drawback that the tactile sensation was greatly deteriorated.

Moreover, it is necessary to improve the stability to skin in the detergent used for skin washing, such as a shampoo and a cleansing agent. Among them, since there is a possibility that a baby or an animal may accidentally swallow it when using it in a baby detergent or a pet detergent, it is preferable that it is safe to eat. For this reason, the development of a cleaning composition which is excellent in safety and a feeling of use, is hypoallergenic, and has a required viscosity is requested|required.

On the other hand, color cosmetics such as makeup cosmetics and sunblock products basically contain pigments, dyes, and fine inorganic particles. To attach them to the skin surface, wax, oil, silicone, synthetic polymer, etc. this is used Accordingly, pigments and the like are deposited on the outermost stratum corneum of the skin, thereby expressing self or protecting the skin from external environments such as ultraviolet rays.

After makeup, cleansing is performed to remove it. Most of the makeup cosmetic ingredients for skin expression are lipophilic, so they are first dissolved and removed with a lipophilic detergent. The general method is to remove it again. In order to solve the inconvenience of such double cleansing, formulations using nonionic surfactants, etc., which wash oil-soluble components relatively well, have been developed in the face wash.

Korean Patent Application Laid-Open No. 10-2012-0009944 "Makeup Cleaner Composition" discloses 'makeup cleaning composition that effectively removes makeup by using a predetermined silicone surfactant and polyol and at the same time provides freshness after washing face'. However, these products also do not have a large cleansing effect, so research and development have been conducted on it. On the other hand, there have been attempts to solve the double cleansing with a single face wash by developing a formulation using a scrub, but there has been a risk of skin damage, which is a limitation of the scrub, or damage to the eyes during face wash.

On the other hand, a cleaning composition containing vegetable oil can be expected to have moisturizing power by oil, but since oil itself does not have a cleaning power, it is prepared by adding a synthetic surfactant or soap powder for a cleaning function.

However, these synthetic surfactants or soap powder may cause skin irritation, in particular, may worsen dry skin such as atopic skin or psoriasis, and may cause irritation to sensitive and delicate skin.

Therefore, most of the commercially available detergent products obtained by saponifying vegetable oil use surfactants having 12 to 16 carbon atoms to form bubbles, but in the case of surfactants with short carbon atoms, bubble formation is easy, but penetration into the skin It quickly causes skin irritation and damages the barrier. Therefore, there is a need for a cleaning composition that maximizes moisturizing power while minimizing irritation to dry skin, atopic symptoms, or delicate skin.

As such, the hypoallergenic and highly moisturizing detergent composition disclosed in Korean Patent Application Laid-Open No. 10-2012-58721 uses saponification of vegetable oil with a high content of fatty acids, thereby having cleansing power and creating rich foam, with little irritation to the skin and moisturizing power. This improved detergent composition relates to the present invention.

The invention imparts cleaning and foaming power to vegetable oil and in order to prepare an oil that is difficult to formulate because it is not soluble in water as a water-based product, the vegetable oil is heated to 80-120° C. and then potassium hydroxide, sodium hydroxide or triethanol A basic substance such as an amine is added and stirred for 1 to 4 hours, more preferably for 3 hours, to prepare and use the triglyceride form of the oil in the form of a vegetable oil saponified with soap.

In addition, detergent products that are usually saponified of vegetable oil have the disadvantage that the time for saponification should be given as short as 1 to 4 hours and as long as 10 to 24 hours. At this time, if the saponification time of the vegetable oil is prolonged, most of the useful components of the oil itself are destroyed, causing a decrease in moisturizing power.

From the background described above, there is a need for an environmentally friendly cleaning composition that has low irritation to the skin and is made of safe ingredients.

Korean Patent Registration No. 10-0671249 (January 12, 2007) Korean Patent Registration No. 10-1554234 (September 14, 2015) Korean Patent Registration No. 10-1936956 (January 03, 2019)

While the present inventors were conducting research to improve the problems accompanying the prior art and to prepare a detergent composition that is hypoallergenic and can expect moisturizing and cleaning power at the same time, a cleaning containing alkanediol and/or ethylhexyl glycerin as main ingredients By confirming that the composition can simultaneously provide moisturizing power, excellent cleaning power, and low skin irritation even if the composition contains a small amount of surfactant, the present invention has been completed.

Accordingly, an object of the present invention is to provide a cleaning composition that is friendly to the human body while maintaining the properties of the cleaning agent, has less irritation to the skin, and has antibacterial and antiseptic properties and does not leave residues.

The object of the present invention as described above is 0.1 to 20% by weight of alkanediol, ethylhexylglycerin or a mixture thereof; 0.1 to 50% by weight of ethanol, 0.01 to 2% by weight of organically modified liquid silicone; And it can be achieved by the cleaning composition, characterized in that consisting of the remaining amount of water.

The detergent composition according to the present invention has less irritation to the skin, has antibacterial and antiseptic properties, and leaves no residue, so it is not only friendly to the human body, but also lowers the freezing point of the detergent composition according to the drop in outdoor air temperature in winter and summer. It has the advantage that it can be used regardless of the season because it can be kept in a liquid state at room temperature by preventing it from solidifying.

The present invention, in one aspect, alkanediol, ethylhexyl glycerin or a mixture thereof 0.1 to 20% by weight; 0.1 to 50% by weight of ethanol, 0.01 to 2% by weight of organically modified liquid silicone; and the remaining amount of water.

Hereinafter, a cleaning composition according to the present invention will be described.

The terms or words used in the present specification and claims are not to be construed as limited in their ordinary or dictionary meanings, and on the principle that the inventor can appropriately define the concept of the term in order to best describe his invention. It should be interpreted as meaning and concept consistent with the technical idea of the present invention. Therefore, since the embodiments described herein and the configurations shown in the drawings are only the most preferred embodiment of the present invention, it is understood that there may be various equivalents and modifications that can be substituted for them at the time of the present application. shall.

Alkanediol and ethylhexylglycerin (EHG), which are the main components of the detergent according to the present invention, have relatively small molecular weights compared to surfactants, but have hydrophilicity and some lipophilic properties. Due to these properties, although they have great efficacy in wiping off non-greasy contaminants, alkanediol and ethylhexylglycerin (EHG) have been studied as catalysts or solvents in cleaning compositions for various purposes. However, it has never been reviewed as the main ingredient of a detergent.

Chemical products containing various surfactants often provide excellent effects, but they also cause side effects in terms of environmental and human health. As an example, dyes, surfactants, and other chemicals contained in window washer fluid enter the vehicle through a blower and are inadvertently inhaled by the driver and passengers. Surfactants added to the washer fluid may be inhaled into the respiratory tract and may affect the human body. Of course, when these many types of surfactants are inhaled into the human body, it is not necessarily safe.

On the other hand, alkanediols or ethylhexylglycerin including butanediol, pentanediol, hexanediol, and octanediol are used as preservatives in the cosmetic field and are recognized as safe for the human body. will have

From this point of view, there is a need for a cleaning agent that is as environmentally friendly and human-friendly as possible. Alkanediol and/or ethylhexylglycerin can satisfy these requirements, while leaving no residue, and providing various functions including moisturizing power, antibacterial power and antiseptic power, it can satisfy desirable requirements as a cleaning agent.

Water and ethanol have a property of easily evaporating and cannot be easily separated when foreign substances are attached to them, whereas alkanediol does not volatilize well because it absorbs moisture due to its high boiling point and remains at a temperature of 38 to 40°C to sufficiently separate foreign substances. it helps to

Alkanediols are complexes of short hydrocarbons with two hydroxyl groups in one molecule. This molecular structure has a high boiling point and low molecular weight, but has hydrophilicity and lipophilicity. Due to these properties, and hard-to-clean contaminants having low lipophilicity can be cleaned well, and can be almost completely removed by rinsing with water, and by minimizing the amount of surfactant, it is possible to provide a composition that is very stable in terms of environmental friendliness. . In addition, when used in the window washer fluid of automobiles, it shows an excellent effect in wiping off insects attached to the windshield of the automobile.

The alkanediol may be butanediol, pentanediol, hexanediol, heptanediol, octanediol, or a mixture thereof. As the number of carbons in the alkanediol increases, the cleaning effect, antibacterial activity and antiseptic activity against highly lipophilic contaminants increase.

In addition, ethylhexyl glycerin is a component containing two hydroxyl groups and has the same functionality as the above-described alkanediols. The alkanediol may be mixed with ethylhexyl glycerin to be used as a main component of a detergent.

As a main component of the detergent, the content of alkanediol and/or ethylhexylglycerin contained in water is suitably about 0.1% to 20% based on the weight of the composition. More preferably, about 0.2% to 15% is suitable. Even more preferably, about 0.5% to 10% may be preferable.

The alkanediol is more preferably at least one selected from the group consisting of 1,3-butanediol (=butylene glycol), 1,2-pentanediol, 1,2-hexanediol, 1,2-octanediol, and mixtures thereof. can be used

When the content of the alkanediol and/or ethylhexyl glycerin is less than a set range, there is a fear that the function including the ability to remove foreign substances, moisturizing power, antibacterial power and antiseptic power may be deteriorated. In addition, above the set range, the economic feasibility according to the increase amount may decrease and there is a possibility that a non-volatile residue may remain, and there is a possibility that the product stability may be deteriorated because it cannot be harmonized with the remaining ingredients.

These characteristics of alkanediol and ethylhexylglycerin wash well with water and leave no residue, so they can be used as special cleaners such as car washer fluid, eyeglasses and contact lens cleaner, etc. , can be beneficially used as a main ingredient in household products such as feminine cleanser and portable wipes. In addition, the cleaning composition of the present invention is applicable to a whiteboard.

Ethanol, the second component of the cleaning composition of the present invention, is a component for doubling the cleaning ability in cooperation with the alkanediol and/or ethylhexylglycerin. Ethanol improves cleaning ability, but leaves no residue by volatilization.

The ethanol may preferably include 0.1 to 50% by weight based on the total weight of the composition. As for the composition of the aqueous cleaning solution of alkanediol and/or ethylhexylglycerin containing ethanol, the content of alkanediol and/or ethylhexylglycerin as a detergent contained in water is more preferably between 0.2% and 20%, and ethanol It may be more preferable that the content includes 0.5 to 45% by weight.

If the content of the ethanol is less than the set range, there is a fear that the synergistic effect of the cleaning power may not come out. In addition, in the range above the set range, there is a possibility that the ability to adhere to the residue is reduced due to volatilization, which may lead to a decrease in the cleaning power.

The third component of the cleaning composition according to the present invention includes a trisiloxane ethoxylate-based super-diffusion surfactant, which is a type of organically modified liquid silicone. It is preferable to use PEG-8 trisiloxane as such a surfactant, and Union Carbide's Silwet L-77 (CAS No. 27306-78-1 or 1369526-66-8) is exemplified.

This can synergistically improve the cleaning power by cooperating with alkanediol and/or ethylhexylglycerin, which are the main components of the cleaning agent. The organically modified liquid silicone acts as a powerful humectant, particularly for high-speed cleaning, and as an emollient when in contact with the skin.

The content of the organically modified liquid silicone may be preferably included in an amount of 0.01 to 2% by weight based on the weight of the total composition of the cleaning agent.

If the content of the organic modified liquid silicone is less than a set range, there is a risk of a decrease in wetting and skin soothing ability. Above the set range, the cleaning power may be increased to some extent, but there is a risk that it is not preferable in terms of environment-friendliness.

The fourth component of the detergent composition according to the present invention is water, and in harmony with the alkanediol and/or ethylhexylglycerin, ethanol and surfactant, it does not freeze even in the winter season and exhibits excellent cleaning power in situations where cleaning is required.

The composition of the present invention has the main characteristics of finding the functionality of each component and the optimal combination ratio thereof to provide an environmentally friendly product in addition to the basic characteristics of cleaning power. In addition, the individual ingredients work together to synergistically exhibit the desired functionality as described above. Therefore, the composition ratio is set in consideration of the effective efficacy of each component and side effects that may occur when applied to various uses, and if it is out of the range of the ratio, there is a fear that the effect may be deteriorated.

In addition, for the purpose of further improving the functionality of the cleaning composition according to the present invention or for enhancing the luxury of a product, or for the purpose of reducing the friction of glass during wiper, it can be commercialized using fragrances, dyes and other additives. there is.
