Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a novel detergent composition, more specifically, a phosphate ester salt surfactant as an essential component.
, a detergent composition containing a higher fatty acid salt [component (2)] and polyethylene glycol [component O], and its purpose is to be mild to the skin and hair, and to have excellent foaming properties. The purpose of the present invention is to provide a cleansing composition.

In recent years, safety requirements for various cleaning agents have become stronger and stronger, and research into the development of new and highly safe surfactants has become active. Even those with weaker effects are being reevaluated to find those with higher toxicity, and many studies are being conducted to improve their effectiveness by combining them with other bases.

Among the many active surfactants, lauryl phosphate ester salt,
Phosphate ester salt-based surfactants (hereinafter referred to as phosphate ester salts) such as myristyl phosphate ester salts are mild to the skin and hair, and have an excellent feel, so they can be used as solid detergents, It is used in shampoos, toothpastes, facial cleansing creams, etc.

However, when used on areas with a lot of oily dirt, such as the face with make-up, hands and feet after labor, etc., it has poor foaming properties and gives the user a sense of anxiety, especially solid detergents, body jumps, etc. For products like No. 1, which are used by lathering with a towel or the like, this weak foaming power was a major drawback that immediately led to a decline in quality evaluation.

Therefore, as a result of extensive research into enhancing the foaming power of phosphate ester salts, the present inventor found that when a phosphate ester salt is used in combination with a higher fatty acid salt, the foaming power does not decrease even against oily stains. The present invention was completed based on the discovery that the foaming properties are improved and that the effect is further significantly improved when polyethylene glycol is used in combination with the foaming properties.

The phosphoric acid ester salts, which are the four components of the cleaning composition of the present invention, are represented by the following general formula (1) or ().

(In the formula, Rl, R2, and R3 represent a saturated or unsaturated hydrocarbon group having 8 to 18 carbon atoms, and X and Y each represent a hydrogen atom, an alkali metal, ammonium, or an alkanolamine having 2 or 3 carbon atoms.) Here, the saturated or unsaturated hydrocarbon group may be linear, branched, or cyclic, and includes, for example, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyly, and unsaturated products thereof. . These hydrocarbon groups may be composed of one kind or a combination of several kinds, and particularly preferred are saturated hydrocarbon groups having an average of 10 to 14 carbon atoms or unsaturated hydrocarbon groups having an average of 16 to 18 carbon atoms. Further, as the counter ion represented by X and Y, sodium is preferable when used in a solid detergent, and potassium or ethanolamines are preferable when used in a liquid detergent. In the present invention, the phosphoric acid ester salt of component (4) is used alone or as a mixture of the compounds represented by the above (1) or () in any proportion, but especially the compound of formula (1) and Compound of formula (river) in weight ratio of 1
Preferably, the ratio is 00:0 to 50:50.

Particularly preferred examples include, for example, sodium mono- or dilauryl phosphate, potassium mono- or dilauryl phosphate, diethanolamine mono- or dilauryl phosphate, triethanolamine mono- or dilauryl phosphate, sodium mono- or dimyristyl phosphate,
Potassium Mono- or Dimyristyl Phosphate, Triethanolamine Mono- or Dimyristyl Phosphate, Sodium Mono- or Dimyristyl Phosphate, Potassium Mono- or Dioryl Phosphate, Potassium Mono- or Dimyristyl Phosphate, Triethanolamine Mono-palmityl Phosphate, Monostearyl Examples include potassium phosphate, monostearyl phosphate triethanolamine, and the like. (4) Component phosphoric acid ester salt is present in the detergent composition in an amount of 5 to 80% by weight (hereinafter simply referred to as "?").
), preferably 10 to 70%.

The higher fatty acid salts, which are the eight components of the detergent composition of the present invention, are represented by the following general formula ().

(In the formula, R is a saturated or unsaturated hydrocarbon group having 7 to 17 carbon atoms, M is an alkali metal, ammonium, or a carbon number 2
Alternatively, the higher fatty acid salt may be prepared by subjecting the higher fatty acid and the alkali to a neutralization reaction in a mixing tank for producing a cleaning composition.

Furthermore, even if a portion of the higher fatty acid salt undergoes salt exchange with the hydrogen counter ion of the phosphate ester salt, this does not impede the effects of the present invention. The 8 component higher fatty acid salts can be used alone or as a mixture of 2 or more.
It is blended so that it is 0%, preferably 5 to 50%.

In the detergent composition of the present invention, the active ingredient and the 8 ingredients are blended within the above ranges, but it is particularly preferable that the blending ratio of the ingredient (4) and ingredient (B) is from 85:15 to 40:60.

Furthermore, the polyethylene glycol of component (C) preferably has a molecular weight of 1,000 to 20,000, and is present in the detergent composition in an amount of 0.5 to 15%, preferably 2 to 1%.
Contains 3%.

Although it may be added in an amount exceeding 15%, no further increase in the effect is observed even if more than this is added. In terms of foaming properties and skin irritation, the cleaning composition of the present invention has a pH value of
(1) is preferably 5.5 to 8.5 when used as a 5% aqueous solution.

In the present invention, the object of the present invention can be achieved to a certain extent by blending 8 components with component (5), but if component (C) is further blended with this, an extremely excellent cleaning composition can be obtained. In addition to these essential ingredients, the composition may also contain solvents such as water, pigments, fragrances, bactericides, etc., depending on the form and purpose of use.
Anti-inflammatory agents, chelating agents, inorganic or organic salts, viscosity modifiers, foam enhancers, preservatives, wetting agents, and other types of surfactants may be added to the extent that they do not interfere with the effects of the present invention. The cleaning composition of the present invention can be manufactured by blending the above-mentioned components by a method known per se, and its form can be selected from various forms such as solid, liquid, powder, granule, and paste. be able to.

The detergent composition of the present invention obtained in this way is gentle on the skin, hair, etc., and also exhibits fine, fine foaming, and shows no decrease in foaming power even against oily stains. It is extremely excellent.
