Description
Technical field
The present invention relates to a kind of cleansing composition, little to skin irritation, have extremely good foaming characteristic and an alveolar substance when it uses under the hard water condition, and have gratifying salubrious sense, moist feeling after cleaning.
Background technology
Because to the low irritant of skin, phosphate surfactant active is often used as the Main Ingredients and Appearance of shampoo or skin cleaning article.
Phosphate (ester) surfactant is the mixture of monoesters and diester normally, and alkylphosphonate contains a kind of phosphate dialkyl ester with more weak foaming characteristic inevitably.Owing to can not provide enough foaming characteristic and alveolar substances when only using phosphate surfactant active as the Main Ingredients and Appearance of detergent, the someone proposes to add the method for auxiliary agent to overcome this shortcoming in phosphate surfactant active.
In addition, knownly in hard water, contain a large amount of Ca
+And/or Mg
2+Ion, for example soap base is easy and these metal ions form soap scums for surfactant, cause weakening of foaming characteristic and alveolar substance, and these soap scums remains in easily on the skin when cleaning, tight sense is often arranged after its result cleans, and the sensation after cleaning is also unsatisfactory.
On the other hand, for example laureth-(1-4) sulfuric ester sodium salt (SodiumLaureth Sulfate) can disperse soap scum to surfactant well, therefore in being usually used in detergent to prevent that soap scum remains on the skin when cleaning.
In Chinese patent application CN1451732 (corresponding Japanese patent application P2004-2632A), a kind of cleansing composition is disclosed, wherein used the mixture of phosphate monoester and di-phosphate ester, and polyoxyethylene alkyl ether sulfate salt or alkyl sulfate.When it used under the hard water condition, though have good foaming characteristic and alveolar substance, the salubrious sense after cleaning also was not enough to satisfactory.
Also there is the also insufficient problem of salubrious sense in disclosed cleansing composition in Japanese patent application P2004-2273A.
In addition, disclosed cleansing composition among the Japanese granted patent P3813563, though good salubrious sense can be provided,, foaming characteristic and alveolar substance were not enough to satisfactory when it used under the hard water condition.
Therefore, the purpose of this invention is to provide a kind of cleansing composition, little to skin irritation, have extremely good foaming characteristic and an alveolar substance when it uses under the hard water condition, and have gratifying salubrious sense, moist feeling after cleaning.
Summary of the invention
The inventor finds, if a kind of cleansing composition of phosphoric acid salt surfactant is cooperated with the betanin of regulation, and compositions by cooperating the specific composition of preserving moisture, higher fatty acids or its salt and an amount of pH regulator agent to obtain therein, little when under the hard water condition, using to skin irritation, have extremely good foaming characteristic and an alveolar substance, and have gratifying salubrious sense, moist feeling after cleaning, thereby finished the present invention.

9Be preferably carbon number 9～17, more preferably 11～17, be preferably 11～13 alkyl especially; M is preferably alkali metal atom, alkanolamine or ammonium, is preferably the such alkali metal atom of potassium or sodium especially.
This higher fatty acid salt can modulate higher fatty acids and alkali generation neutralization reaction by in the mating groove of making cleansing composition.And the part of higher fatty acid salt also can be replaced with the equilibrium ion of phosphate ester salt, and does not hinder effect of the present invention.
Composition (E) plays the effect of improving alveolar substance,, causes clammy alveolar substance that is, has also improved foaming characteristic in addition.
Can use composition (E) higher fatty acids or its salt separately, or cooperate and use composition (E) higher fatty acids or its salt more than 2 kinds.The content of composition (E) considers that from the aspect that gives cleansing composition detergency of the present invention, foaming characteristic be preferably 0.1～0.5 weight %, more preferably 0.2～0.5 weight % is preferably 0.4～0.5 weight % especially.
In addition, consider the effect that has gratifying skin sense after cleaning, in the present invention, total content with respect to composition (A), composition (B), composition (C) and composition (D), the part by weight [(A)+(B)+(C)+(D)]/(E) of the content of composition (E) is 99/1～98/2, preferred 88/1～75/1, more preferably 85/1～80/1.
In addition, in order to regulate the pH value of cleansing composition of the present invention, also contain an amount of pH regulator agent in the cleansing composition of the present invention.The pH regulator agent of Shi Yonging in the present invention can be used the pH regulator agent of using usually in cleansing composition.By adding an amount of pH regulator agent, make the pH value of cleansing composition of the present invention reach 6～7.
Cleansing composition of the present invention, by and with composition (A), (B), (C), (D) and (E), (F), and content by making them and ratio are within above-mentioned scope, even when under the hard water condition, using, when also can reach the inherent cleaning strength of phosphoric acid ester surfactant, low irritant, also have extremely good foaming characteristic and alveolar substance, and have gratifying salubrious sense, moist feeling after cleaning.
Corresponding to application target, in the scope of harmless effect of the present invention, can also cooperate an amount of pigment, spice, antibacterial, antiinflammatory, chelating agen, suds booster, thickening agent, viscosity modifier, pearling agent, antiseptic and other surfactants etc. in the cleansing composition of the present invention.
The manufacture method of cleansing composition of the present invention comprises, for example, and following steps:
1) modulation contains the mixture of composition (A)～(F);
2) container of then these mixture being packed into.
To composition (A)～when (F) mixing, should first blending ingredients (C) and component (E), and then blending ingredients (F), remix component (A) and component (B) afterwards, last blending ingredients (D).Because viscosity can increase during known cooperation composition (A), therefore preferably under 40～80 ℃, heat.
Cleansing composition of the present invention is because the alkyl phosphate monoester (a in its composition (A)
1) and alkyl phosphoric acid diester (a
2) weight ratio (a
1)/(a
2) be 85/15～50/50, therefore the phenomenon that viscosity increases fast can not take place blended the time, can under the condition below the 10000msPas, make, and as (a
1)/(a
2) be 85/15～65/35 o'clock, the dissolution time during cooperation is short, can suppress well owing to the abnormal smells from the patient of the hot use raw material that causes and the deterioration of color and luster, and is therefore preferred.
