Description

Liquid Cleaner Composition

The present invention relates to a liquid detergent composition, and more particularly, to a liquid detergent composition which is safe due to less irritation to skin and hair, and at the same time has an excellent feeling of use and is stable even for long term storage.

Recently, the problem of safety of various detergents has been frequently emphasized, and research on new high safety hypoallergenic surfactants is being actively conducted. Also, among the surfactants used in the past, a relatively high safety surfactant is combined with other bases. There was an attempt to improve the effect. In particular, among the many surfactants, phosphate ester salt surfactants such as lauryl phosphate ester salts and myristyl phosphate ester salts are hypoallergenic to skin and hair and have good rinsing properties, and thus are expected to be useful as skin cleaners for humans. There is active research.

For example, Japanese Patent Publication No. 82-47959 discloses a technique of using a mixture obtained by mixing monoalkyl phosphate and dialkyl phosphate in a composition ratio of 100: 0 to 80:20 as a cleaning agent. Poor bubble properties, especially when used as a lot of contaminants or body shampoo, such as a weak foaming power and had the disadvantage of poor stability during long-term storage.

In order to improve the poor bubble characteristics, Japanese Patent Publication No. 84-18440 used a mixture of a fatty acid salt and a polyethylene glycol having a molecular weight of 1,000 to 20,000 in a phosphate ester salt, but these components have the effect of enhancing the foaming force. The long-term stability was bad and the skin texture was poor after use.

In addition, Japanese Patent Application Laid-Open Nos. 83-101197, 83-103598, 84-74196, and 87-148599 disclose a technique of mixing and using a phosphate ester salt-based surfactant and a synthetic surfactant. Since the surfactant is adsorbed on the skin or the hair, there is a disadvantage that the rinsing property is bad, such as a lot of slippery feeling and an unpleasant texture.

Accordingly, the present inventors have studied diligently to solve the above disadvantages, and as a result, the polymerization quaternary ammonium salt of hydroxyethyl cellulose reacted with lauryldimethylammonium having an epoxide substituted in a mixture of a phosphate ester-based surfactant and a higher fatty acid salt was used. When formulated, the skin and hair are less irritating and safe, without a greasy feeling, good rinsing, excellent after-use, and excellent long-term storage stability. It was completed.

That is, an object of the present invention is to provide a liquid detergent composition that is safe and excellent in use and maintains a stable state even for long-term storage due to less irritation to skin and hair.

Hereinafter, the present invention will be described in detail.

In the liquid detergent composition, (a) 3 to 60% by weight of one or two or more phosphate ester salt surfactants selected from the compounds represented by the following general formula (I) or (II): B) 2 to 60% by weight of one or more higher fatty acid salts selected from compounds represented by the following general formula (III), and (c) an epoxide substituted by the following general formula (IV): It is a liquid detergent composition characterized in that it contains 0.1 to 10% by weight of a quaternary ammonium salt of hydroxyethyl cellulose reacted with lauryldimethylammonium.

Wherein R ₁ , R ₂ , R ₃ and R ₄ may be the same or different, each represent a saturated or unsaturated hydrocarbon group having 8 to 18 carbon atoms, R ₅ is a lauryl group, and X and Y may be the same or different Each represents a hydrogen atom, an alkali metal, ammonium or an alkanolamine having 2 to 3 carbon atoms, M represents an alkali metal, ammonium or an alkanolamine having 2 to 3 carbon atoms, and l, m and n are each 0 to An integer between 10 and r and s are each an integer between 1 and 10.

Referring to the present invention in more detail as follows.

In the present invention, as the phosphate ester salt surfactant, one or two or more selected from the compounds represented by the general formula (I) or the general formula (II) are used.

These phosphate ester salt surfactants are compounds in which R ₁ , R ₂ and R ₃ are each a saturated or unsaturated hydrocarbon group having 8 to 18 carbon atoms in the general formula (I) or (II), and these saturated or unsaturated hydrocarbon groups It may be linear, pulverized or cyclic, or may be one or a combination of these hydrocarbon groups, and particularly preferably a saturated hydrocarbon group having an average carbon number of 10 to 14 or an unsaturated hydrocarbon group having an average carbon number of 16 to 18. On the other hand, X and Y in the general formula (I) or (II) may be the same or different, each is a hydrogen atom, an alkali metal, ammonium or an alkanolamine having 2 to 3 carbon atoms, in particular in the case of a liquid detergent potassium or Amines are suitable. In addition, in Formula (I) or (II), 1, m, and n are integers between 0 and 10, and thus no ethylene oxide may be added or 1 to 10 added.

As a phosphate ester salt type surfactant of this invention, the compound represented by the said General formula (I) or (II) may be used independently, and these may be mixed and used. In particular, the compound of the general formula (I) and the compound of the general formula (II) are preferably mixed in a weight ratio of 100: 0 to 50:50, so that the compound of the general formula (II) is used more than the ratio. If the bubble properties worsen and the skin penetration increases, it will irritate the skin.

In the present invention, the phosphate ester salt-based surfactant is contained in the total composition of 3 to 60% by weight, preferably 10 to 50% by weight, if contained more than the above range degreasing power is too strong to irritate the skin It is difficult to maintain the liquid phase, and when it is contained below the above range, the cleaning power is lowered and the hypoallergenic effect, which is a characteristic of the phosphate ester salt surfactant, cannot be exhibited.

Meanwhile, as the higher fatty acid salt of the present invention, one or two or more kinds of compounds of the general formula (III) may be selected and used.

The higher fatty acid salt may be used alone by selecting one kind from the compounds of the general formula (III), may be used by selecting two or more kinds thereof, and the higher fatty acid salt is used in the preparation of the cleaning composition. It may be prepared by neutralizing higher fatty acids and the corresponding alkali in the middle of the season.

In the present invention, the higher fatty acid salt is contained in the total composition of 2 to 60% by weight, preferably 5 to 40% by weight, if it contains more than the above range, it is difficult to maintain the formulation and the cleaning power is enhanced, PH When the content is less than the above range, the phosphate ester salt-based surfactant is used a lot, so that the degreasing power becomes stronger, thereby irritating the skin.

In the liquid detergent composition which concerns on this invention, it is preferable that the weight ratio of the said phosphate ester type surfactant component and the said higher fatty acid salt component is 90: 10-30: 70. If the phosphate ester salt-based surfactant is used at a higher ratio than the above, the bubble properties deteriorate, and when the higher fatty acid salt is used at a higher ratio, the pH becomes too high, making it difficult to obtain a neutral detergent composition.

In the composition of the present invention, the polymerization quaternary ammonium salt of hydroxyethyl cellulose reacted with lauryldimethylammonium substituted with epoxide represented by the general formula (IV) (The Cosmetictoiletry and Fragrance Association name: Polyquaternium-24) 0.1 to 10% by weight, preferably 0.1 to 5% by weight is good to contain, less than the above range does not exhibit the full effect of the present invention, if contained more than the above range will form a gel phase It is too slippery and feels bad.
