Description

Transparent concentrated shampoo composition {CLEARLY CONCENTRATED SHAMPOO COMPOSITION}

[Industrial use]

The present invention relates to a concentrated shampoo composition that maintains transparency even at low temperatures, and more particularly, by containing an appropriate amount of sodium chloride, polyethylene glycol 400 (represented by PEG 400 or PEG-8) and alkylpolyglucoside in the concentrated shampoo composition. The present invention relates to a concentrated shampoo composition that maintains transparency without suspending even at a low temperature of 0 ° C or lower.

[Prior art]

Concentrated shampoo is a shampoo which is characterized by sufficient concentration of surfactant to 2 ~ 3 times of general shampoo and shows sufficient washing and conditioning effect even in small amount. It has not been widely used in Korea but has been widely used in foreign markets for a long time. It can be called a shampoo.

The conventional technical problem of the concentrated shampoo is that in the case of the transparent concentrated shampoo, since the concentration of the surfactant is high, when the surfactant and other compositions are supersaturated when stored at low temperature, the crystallinity of the shampoo is suspended as the micelle is crystallized. will be. In most cases, the transparent shampoo is contained in a transparent container, so that the appearance of the product is changed due to the temperature drop during the distribution and storage of the product. Therefore, in order to maintain transparency even at low temperatures, it may be said that there is a method of increasing solubility by adding an appropriate solubilizer or adjusting the ratio of anionic, amphoteric and nonionic surfactants, that is, a combination of surfactants.

Currently, little general knowledge or patents are known about maintaining transparency at low temperatures. Even general transparent shampoos, which are not commercialized, have a problem of losing transparency and suspending at low temperature.

The present invention is to solve the above problems, it is to provide a concentrated shampoo composition that can maintain transparency even at a low temperature below 0 ℃ as a transparent concentrated shampoo surfactant is two to three times the existing shampoo.

[Means for solving the problem]

In order to achieve the above object,

The present invention is 2 to 4% by weight of sodium chloride, 4 to 8% by weight of polyethylene glycol 400, 4 to 6% by weight of an alkylpolyglucoside represented by the following formula (1), and an anion, or an anionic and amphoteric surfactant 30 It provides a shampoo composition, characterized in that it comprises from 40% by weight.

[Formula 1]

RO- (G) m

Where

R represents a branched or straight chain saturated or unsaturated hydrocarbon having 5 to 30 carbon atoms, preferably 8 to 18 carbon atoms,

G is a saccharide selected from the group consisting of glucose, xylose, lactose, fructose, mannose and derivatives thereof consisting of 5 to 6 carbons,

m represents a degree of polymerization as 1 to 10, preferably 1 to 2.

Representative compounds of the alkylpolyglucoside of Formula 1 include lauryl polyglucose, decylpolyglucose and the like.

The inventors of the present invention have made a major interest in solving the problem of suspension at low temperatures of the transparent concentrated shampoo while studying the transparent concentrated shampoo, and the solubility of the surfactant is very high in the above-described specific region of the present invention, and especially its transparency at low temperatures. Found to be retained.

In the manufacturing process of concentrated shampoo, sodium chloride (sodium chloride is commonly used as a thickener as a viscosity lowering agent due to the increased viscosity due to the high concentration of the surfactant, but when the content is increased to 1 to 2% by weight or more, the viscosity decreases. ), Polyethylene glycol 400 is also a solvent that can be used as a viscosity lowering agent.

In addition, nonionic surfactants are generally known to have good transparency at low temperatures due to their low kraft points. As a result of examining nonionic surfactants by type and content, 4 to 6 wt% of the alkylpolyglucoside of Formula 1 is added and the viscosity is lowered. When zero concentration of sodium glycol and polyethylene glycol 400 having a function of viscosity lowering agent or solubilizer together in the content of the claims of the present invention was able to prepare a concentrated shampoo that maintains transparency even at low temperatures.

In general, when the temperature is lowered, the solubility of the surfactant is lowered and thus the supersaturated state is suspended. As a result of the crystallization of micelles, the solubility of the surfactant is greatly increased when sodium chloride and polyethylene glycol 400 are added as the content of the present invention. It is estimated that transparency at low temperature is maintained by doing so. These sodium chloride and polyethylene 400 significantly affected the size, structure, and solubility of the micelles depending on the amount added, so that when added over the claims of the present invention, the solubility of the surfactant was lowered and transparency at low temperatures was not maintained.

At this time, 30 to 40% by weight of an anion or an anionic and amphoteric surfactant is added, and as an anionic surfactant from the group consisting of sodium lauryl sulfate, sodium polyoxyethylene lauryl sulfate, ammonium lauryl sulfate, sodium cocoyl glutamate and mixtures thereof It is preferable to use at least 1 sort (s) selected, and it is preferable that at least 1 sort (s) is chosen from the group which consists of cocamidopropyl betaine, coco amppocarboxyglycinate, and a mixture thereof as an amphoteric surfactant.

When the amount of the surfactant is constant in the claims of the present invention, the viscosity of the shampoo changes as the amount of sodium chloride and polyethylene glycol 400 changes, and thus, the amount of the shampoo can be adjusted to obtain a desired shampoo.

Hereinafter, the present invention will be described in detail as comparative examples and examples. However, the present invention is not limited to these examples.
