Description

Cleansing composition having stable viscosity in a wide temperature range

FIG. 1 shows the results of measuring the viscosity change in the wide temperature range (0 ° C to 50 ° C) of the cleaning compositions of Examples 1 to 3 and Comparative Examples 1 and 2. FIG.

The present invention relates to detergent compositions having stable viscosities over a wide range of temperatures. More specifically, in the human cleansing composition for hair and skin care, the present invention encapsulates an oily ingredient useful for skin or hair in a composition, and at the same time, a room temperature (25) for the purpose of stability corresponding to the floating and sedimentation of these capsules. Methacrylic acid / C ₁ -C ₄ alkyl acrylate copolymer and cetyl alcohol so that the difference in viscosity in the wide temperature range (0 ° C. to 50 ° C.) is kept below 15 ps.

(cetyl alcohol) or stearyl alcohol, the present invention relates to a human cleansing composition comprising a single or mixed use.

The detergent composition of the present invention maintains a very small and constant level of viscosity at room temperature (25 ° C.) and in a wide range of temperature ranges (0 ° C. to 50 ° C.), according to temperature changes. By making it possible to produce a product having a stable viscosity against viscosity decrease and rise, the stability of these components is very excellent against floating or sedimentation, especially when the contents contain an oil-containing capsule with a large specific gravity difference, as in the present invention. In addition, the viscosity of the product in these temperature range is maintained at a constant level to provide a human detergent composition that can take the same feeling of use of the product, such as spreadability and spreadability in a wide temperature range.

Detergents used to decontaminate hair and skin to keep them clean and beautiful, along with basic functions such as decontaminating, nourishing or conditioning hair and skin, are another essential ingredient. There are inherent requirements such as stability and usability, and various researches for improving these essential functions as well as various studies for improving essential elements that are essential for them are also attempted.

For example, hair is damaged by various damage factors such as physical, chemical, and environmental damage, and roughness is increased, and softness and softening effect are lost due to loss of shine, and accordingly, frictional force is increased, making it difficult to clean the hair during combing and the like. This can cause problems such as cuts or split ends. In order to solve this problem, shampoo, which is a recent hair cleaner, adds various conditioning ingredients and hair protection ingredients, and one of the widely used ingredients is water insoluble non-volatile dimethicone, cyclomethicone, and aminated silicone. Oils such as silicones, such as amodimethicone and trimethyl silylamodimethicone, and derivatives thereof and ethers such as dicapriryl ether, hydrocarbon oils, fat soluble vitamins, mineral oils, vegetable oils and the like, are widely used. It is used. Among silicones, low viscosity dimethicone and cyclomethicone of 10,000 centistokes or less have excellent softening effect from the wet hair to the process of drying and drying, and also the aminated silicone, amodimethicone and trimethyl In the case of silyl amodimethicone and the like, it has excellent affinity with hair, and provides various characteristics such as excellent softness, gloss, smoothness and hair damage prevention, and recovery of damage not only in the wet condition but also after drying. Oily ingredients such as ethers, hydrocarbon oils, fat-soluble vitamins, mineral oils and vegetable oils also provide a smooth and supple feel when washing, as well as softness, shine, smoothness and hair damage prevention and recovery of damage even after drying. Because it shows a variety of beneficial effects, for human cleansing compositions containing these components Research is actively underway.

However, silicone components such as aminated silicon, amodimethicone, trimethylsilyl amodimethicone, and cyclomethicone among the silicone components may be difficult to recover due to lowered viscosity during preparation of the detergent composition. Even when salts or other thickeners are used to restore the viscosity, the compatibility (stability) in the detergent composition is poor, causing a problem that the viscosity falls easily over time. In the cleaning composition used as a base material, the oily component is separated by the specific gravity difference with water and compatibility problems, and the value of the composition is often lost.

In order to overcome the stability problems such as viscosity decrease and flotation, and to obtain the beneficial parts provided by the silicone and oily components, these components are generally used as vegetable polymers such as agar, melanin, alginic acid derivatives and cellulose, and animal polymers such as gelatin and chitosan. Synthetic polymers, such as polyamide, polyvinyl alcohol, and derivatives thereof, are encapsulated using the same, and are contained in the cleaning composition.

The purpose of encapsulating a substance by encapsulating it in a capsule is to make it easy to handle by forming a powder shape surrounding the liquid, or to control the release form by slowly releasing the enclosed inner substance, or to leave the substance reacting with each other if left as it is. Encapsulate and isolate, mix and react as needed, avoid volatilization of volatile substances, or use ingredients in compositions without negative or adverse effects on ingredients that affect the composition and properties of the composition. To change. It is used in pigments, dyes, food and food additives, adhesives, detergents, and photographic medicines.The capsules include water-soluble proteins such as gelatin and casein, carbohydrates such as cellulose and cellulose-derived polymers, and vinyl compounds and phthalic anhydrides. Synthetic polymers, such as a copolymer of, are used.

Capsules made through this method have a specific gravity of 0.80 to 1.30, depending on the material used as the shell and the type and content of the material filled in the core, in which case the specific gravity with the contents containing the capsule Because of the difference in floating and sedimentation of these capsules in the detergent composition, it is very advantageous to keep the specific gravity of the capsule and the specific gravity of the composition containing these capsules to a similar level as much as possible to prevent their floating or sedimentation. Do. However, there is a problem in producing capsules of desired properties and maintaining the properties of the compositions containing these capsules, so that there is a limit in obtaining a similar level of specific gravity between the two. Therefore, if there is a specific gravity difference between the capsule and its contents, it is also very important that these capsules remain stable in the composition for a long time without sedimentation or floating phenomenon, and for this purpose, a detergent composition may be added by the addition of a salt such as NaCl. A method of increasing the viscosity of the resin, using an acrylic synthetic polymer, PVM / MA decadiene cross polymer (KR0234547), or the like is used. However, there is a limit to stabilizing these oily components or capsules for a long time without floating or sedimentation using salts such as NaCl alone, and acrylics (acrylates / C10-30 alkyl acrylate cross).

In the case of polymers, the viscosity in the high temperature range (40 ° C to 50 ° C) is lower than the viscosity at room temperature (25 ° C) by more than 35 ps, and the viscosity is low at room temperature (25 ° C to 10 ° C). Lower than 20 ps compared to the viscosity at ℃, and in the case of stabilization using PVM / MA decadiene cross-polymer, the viscosity at low temperature (0 ℃ to 10 ℃) is higher than 30ps compared to the viscosity at room temperature (25 ℃) Low in difference, high temperature zone

The viscosity at (40 ° C. to 50 ° C.) also shows a characteristic of being lowered by a difference of at least 35 ps compared to the viscosity at room temperature (25 ° C.). In addition, when only methacrylic acid / C ₁ -C ₄ alkyl acrylate copolymer is used without using cetyl or stearyl alcohol, the viscosity at low temperature (0 ° C. to 10 ° C.) is reduced to that at room temperature (25 ° C.). Compared to the higher than 50ps, the viscosity is low, the viscosity at low temperature (0 ℃ to 10 ℃) has a disadvantage that the lower than 30ps difference than the viscosity at room temperature. In this case, when the viscosity difference is significantly lower than 20 ps to 30 ps as compared with the viscosity at room temperature (25 ° C.), separation phenomenon due to floating or sedimentation of oily components or capsules is very easy to occur, and room temperature

If the viscosity difference is significantly higher than 20 ps to 30 ps compared to the viscosity at (25 ° C.), problems such as being difficult to pour out of the container when the product is used or not easily spread or spread when applied to the hair or skin are indicated. Will be displayed.

Therefore, in the present invention, a silicone component and a dicapri that cause a viscosity decrease in a detergent composition such as dimethicone, cyclomethicone, and amodimethicone, which are mixed with low and high viscosity silicones and low viscosity silicones, resulting in low viscosity. Oils such as ether, such as reel ether, hydrocarbon oil, fat soluble vitamins, mineral oil, vegetable oil, etc. are mixed and gelatin capsules, 0.01 ~ 1.0mm capsule diameter and 0.80 ~ 1.30 specific gravity of 1N to 100N Encapsulating the outer shell when the force is applied and encapsulating it in the composition, the difference between the viscosity change at room temperature (25 ℃) and the viscosity change in the wide temperature range (0 ℃ to 50 ℃) to minimize the width of these capsules for the purpose of improving stability to sedimentation is among methacrylic acid / C ₁ -C ₄ alkyl acrylate copolymer and the fatty acid carbon number of 16 By using Cetyl alcohol and 18 carbon atoms stearyl alcohol alone or in combination, the difference in viscosity at room temperature (25 ° C) and viscosity change in a wide range of temperature range (0 ° C to 50 ° C) does not exceed 15ps. While solving the stability-related problems of separation of oily components and capsules of the detergent, the excellent properties such that the usability, such as spreadability, spreadability in a wide temperature range (0 ℃ to 50 ℃) exhibits a constant level regardless of temperature The present invention has been accomplished by discovering that a human body cleanser composition can be prepared.

The present invention relates to a detergent composition having a stable viscosity in a wide temperature range from 0 ° C to 50 ° C, comprising a capsule containing an oily component as a core material, methacrylic acid / C ₁ -C ₄ alkylacrylate copolymer, and cetyl or stearyl The present invention relates to a human cleansing composition comprising using alcohol alone or in combination.

According to the present invention, a low viscosity or an ingredient that exhibits additional functions such as excellent softness, gloss, and smoothness as well as a basic function of removing contamination of hair and skin to keep it clean and beautiful and removing contamination attached to hair and skin. The main components are silicones such as dimethicone, cyclomethicone and amodimethicone, which are made of low viscosity by mixing high viscosity silicone and low viscosity silicone, and these components include ethers such as dicaprylyl ether, hydrocarbon oil, By encapsulating oily ingredients such as fat-soluble vitamins, mineral oils, and vegetable oils, it contains capsules that have improved stability against viscosity reduction of the cleaning composition according to the use of low viscosity and low viscosity silicone, and the stability corresponding to floating and sedimentation of the capsules.
