DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is characterized by containing trehalose as a scrub material, and has excellent exfoliating and massage effects, high safety and moisturizing properties on the skin, and excellent skin feel. The present invention relates to an agent composition.

[0002]

2. Description of the Related Art Consumers' awareness of cleanliness has been improving year by year, and various functions and effects have been demanded as a basis of skin care, especially for a cleaning agent. In recent years, as such functions and effects, a cleaning composition containing a scrub material and having a physical cleaning function and a massage function has been particularly attracting attention. Various methods for cleaning the skin with physical force have been known since ancient times.Such scrub particles used in cleaning compositions include natural plants such as almond meal, oatmeal, apricot, and walnut. Materials, inorganic materials such as silica, bentonite and aluminum oxide, and synthetic polymer materials such as polyethylene and polystyrene are used. In general, the user of the scrubbing agent-containing cleaning agent is used for the purpose of preventing acne by removing dirt and sebum of pores and skin grooves, preventing oil floating, or using a scrubbing effect such as physically removing old dead skin cells. It is used in anticipation of skin massage effect by promoting blood circulation.

[0003] On the other hand, on the other hand, due to the strong detergency, the skin may be dried after the cleaning, leading to itching and inflammation. Further, abrasions due to excessive physical irritation by the scrub particles and accidents such as entering the eyes and damaging the eyeballs occurred, causing problems. Therefore, research on a soft scrub material having elasticity and a scrub material that disperses and atomizes has been promoted, but the development of a scrub material-containing cleaning agent that is highly safe against the skin and has excellent usability and effects has been led. Not in. In addition, although it has been proposed to mix sodium chloride as a soluble scrub material, it has problems such as `` if it enters the eyes or touches a wound, sneaks '' or `` poor foaming '', Not yet satisfied.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a skin cleansing composition which is excellent in exfoliating effect and massage effect, has high skin safety and moisturizing property, and is excellent in use feeling. Aim.

[0005]

Means for Solving the Problems As a result of intensive studies, the present inventors have found that by adding trehalose having a saturation solubility to water or higher as a scrubbing material to a detergent, it is excellent in exfoliating effect and massage effect, and The present inventors have found that a skin cleansing composition having high skin safety and moisturizing properties and excellent feeling in use can be obtained, and completed the present invention. That is, the present invention provides a skin cleansing composition characterized by containing trehalose having a saturation solubility in water or higher.

[0006] Trehalose to be added to the detergent composition of the present invention is a non-reducing disaccharide in which two molecules of glucose are linked by α-1,1 and is a sugar that widely exists in nature such as plants and microorganisms. It is a saccharide that has very excellent properties such as non-reducing properties, pH stability, and crystal solubility when blended as a scrubbing material in various detergents. The average particle size of trehalose is preferably 150 μm to 5000 μm particles, particularly preferably 200 μm to 2000 μm particles. If the ratio is below this range, a sufficient feeling of use tends not to be obtained. If the ratio exceeds this range, uncomfortable feeling and damage to the skin tend to occur.

The amount of trehalose used in the present invention is as follows:
Although it can be appropriately selected according to the actual application form, it needs to have a saturation solubility or higher in water in the detergent composition. When the solubility is less than the saturation solubility, trehalose dissolves in the detergent composition and cannot be present as a scrub material, and the intended effect cannot be obtained. The desired effect due to dissolution is not achieved. Here, the term “saturated solubility or higher” means that the trehalose is soluble in water in the detergent composition or more, and 35.6% or more based on the total weight of trehalose and water. Further, since the saturation solubility varies depending on the temperature, it is preferably 60% or more based on the total weight of trehalose and water in order to exhibit a scrub effect in the detergent. The upper limit of the blending is not particularly limited in view of the effects of the present invention. However, if the amount is extremely large, problems arise in terms of usability as a detergent and in terms of function.

[0008] As the surfactant used in the present invention, any surfactant which is commonly used in cleansing agents such as face wash, hair shampoo and body shampoo can be used. Anionic, cationic, amphoteric, A nonionic surfactant can be used and is not particularly limited. Examples of the anionic surfactant include fatty acid soap, alkyl sulfate, polyoxyethylene alkyl ether sulfate, polyoxyethylene alkyl ether carboxylate, higher fatty acid amide sulfonate, dialkyl sulfosuccinate, alkyl allyl sulfonate, and glycerin. Fatty acid ester sulfate, higher fatty acid alkylolamide sulfate, α-olefin sulfonate, alkyl phosphate, N-acyl glutamate, N-
Examples include acyltaurine, N-acyl sarcosine salts, isethion sulfate, collagen hydrolyzate acyl compounds, and the like. In any case, alkali metal salts such as sodium, potassium, and magnesium, organic amine salts such as triethanolamine, and alkaline amino acid salts such as L-arginine can be used.

Examples of the above cationic surfactant include alkylamine salts, polyamine fatty acid salts, alkanolamine fatty acid salts, and alkyl quaternary ammonium salts. Examples of the amphoteric surfactant include an amino acid type, a betaine type, a sulfate type, a sulfonic acid type and a phosphate type amphoteric surfactant. As the nonionic surfactant, polyoxyalkyl ether, polyoxyethylene polyoxypropylene alkyl ether,
Sorbitan fatty acid ester, fatty acid alkylolamide, amine oxide and the like can be mentioned. The amount of these surfactants is not particularly limited, but is preferably 1% or more, and more preferably 3% or more. Below this range, satisfactory detergency and foaming during use are difficult to obtain.

The water-soluble polymer used in the present invention is soluble in water, exhibits a thickening behavior, and contains trehalose particles in the system.
Any material that can be stably dispersed and held can be used. A polymer that is widely used in cosmetics and the like and is highly safe for the human body is desirable, and any type of polymer of natural, semi-synthetic, synthetic, and inorganic types can be used. The natural water-soluble polymers can be classified into plant-based, microbial-based, animal-based, and the like. Examples of plant-based systems include guar gum, locust bean gum, quince seed gum, carrageenan, alginic acid, gum arabic, and pectin. , Starch and the like. Also, as a microbial system,
Xanthan gum, pullulan, juran gum and the like. In addition, animal systems include gelatin, casein, hyaluronic acid, chitosan, collagen and the like. As the semi-synthetic water-soluble polymer, cellulose derivatives,
Alginic acid derivatives, starch derivatives and the like can be classified. Examples of the cellulose derivatives include methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose salts, and cationized cellulose. Examples of the alginic acid derivatives include ammonium alginate and propylene glycol alginate. Further, the starch derivatives include solubilized starch, carboxymethyl starch, methyl starch and the like. The synthetic water-soluble polymers are classified into vinyl, acrylic, and the like. Examples of the vinyl include polyvinyl alcohol, polyvinylpyrrolidone, and carboxyvinyl polymer. In addition, examples of the acrylic type include sodium polyacrylate and polyvinyl methacrylate. Other examples include polyethylene glycol and an ethylene oxide / propylene oxide block copolymer. Examples of the inorganic water-soluble polymer include bentonite and finely divided silicon oxide.

The amount of these water-soluble polymers is not particularly limited, but is preferably 0.01% or more, and more preferably 0.1% or more. When the content is less than 0.01%, it becomes difficult to stably disperse and maintain trehalose particles as a scrub material in the system. On the other hand, if the amount of the water-soluble polymer exceeds 30%, problems such as an increase in slimy feeling during use and an increase in cost arise. Therefore, the amount is preferably less than 20%, more preferably 20% or less.

[0012] In addition, as the compounding components, wetting agents, oily components, pigments, fragrances, anti-inflammatory agents, vitamins, bactericides, preservatives, sequestering agents, ultraviolet absorbers, herbal extracts, and the like can be used to effect the present invention. It can be blended within a range that does not impair.

The detergent composition of the present invention can be widely used as a skin cleanser such as a whole body cleanser, a solid soap, a facial cleanser and the like, and the form thereof is cream, gel, solid or liquid. Can be arbitrarily selected.
