Description
Technical field
The present invention relates to the soil release method of liquid detergent composition and clothing.
Background technology
Kai Fa clothing focused on it with the heavy liquid detergent and removed the dirt that mud, sebum, wet goods cause in the past, can not fully remove the dirt of dying of ight soil, urine, fruit juice etc.Usually, use SYNTHETIC OPTICAL WHITNER based on oxidation bleaching for such dirt of dying, ordinary consumer separately uses so-called general liquid detergent and SYNTHETIC OPTICAL WHITNER, thereby removes these dirts.
On the other hand, have liquid laundry for baby with the such commodity group of detergent, it is in order to clean diaper for baby, clothing, bedding etc., guaranteed does not have bleaching, no fluorescence, without phosphorus such security comprehensively, and do not use SYNTHETIC OPTICAL WHITNER, but have high detergency for the dirt of dying that aforementioned ight soil urine is dyed etc.This liquid laundry for baby is most usually for fatty acid soaps and polyethylene oxide alkyl ethers being the detergent of the weakly alkaline of main component to alkalescence with lotion.
In JP-A2002-138364, disclose, be combined with high-concentration chelating agent, pH in the high alkalinity more than 10, temperature under specified conditions such more than 50 ℃, clean the method for diaper with the alkaline ablution that contains water-soluble chelator and SYNTHETIC OPTICAL WHITNER.
In addition, in JP-A5-239493 and JP-A6-299191 etc., disclose the liquid detergent composition of use alkyl glycoside (alkyl polysaccharide surfactant), its clean ability excellence, reduced the damage of clothing effectively and improved the storage stability of goods effectively.And, the detergent composition that contains alkyl poly glucoside and other specific nonionogenic tenside is disclosed in JP-A4-292697.
Summary of the invention
The present invention relates to a kind of liquid detergent composition, it contains:
(A) alkyl glycoside: 5～20 weight %;
(B) hydroxycarboxylic acid type sequestrant: 10～30 weight %; With
(C) polyocarboxy acid type sequestrant: 1～10 weight %,
Wherein the weight ratio of (A)/(B) is 0.2～1, and weight ratio (B)/(C) is 1～10.
The invention still further relates to and make aforesaid liquid cleansing composition and the contacted method of dying dirt of removing clothing of clothing, and the aforesaid liquid cleansing composition is used for the purposes of clothing.
Embodiment
Though the method for JP-A2002-138364 is applicable to the method for cleaning of commercial usefulness, the simple and easy method of the routine of conduct in general family is difficult to be suitable for.In addition, for existing liquid laundry lotion for baby, wish in the catch greasy sliding sense and the skin irritation that produce when touching stoste, there is further improvement the aspect to cause that clothing hardens when repeatedly cleaning etc.With regard in this respect, the liquid detergent composition of finding JP-A5-239493, JP-A6-299191 can reduce the storage stability that also can improve goods to the damage of clothing, but when obtaining these effects, in the cleaning of fibre product for baby, wish for cause by ight soil and urine dye dirt also can access excellent clean ability aspect further improvement is arranged.The liquid detergent composition that obtains in JP-A4-292697 does not have transparent outward appearance, and stability also remains to be improved.
Usually, selecting when cleaning ability from the height of dying dirt of the excremental dirt of ight soil, urine etc. and the dirt of fruit juice etc., effective means is that high density ground cooperates sequestrant, but, also do not have to find in such high-concentration chelating agent system the composition of matching surface promoting agent stably so far.
The object of the present invention is to provide a kind of liquid detergent composition, it is for dying dirt, particularly has excellent clean ability from ight soil, these excremental dirts of dying of urine, not greasy sliding sense and xerosis cutis when hand contact stoste, the cleaned clothes sense of not hardening, outward appearance is good, excellent in stability.
The present inventor finds to use with specified quantitative, specified proportion the cleansing composition of alkyl glycoside, hydroxycarboxylic acid type sequestrant and polyocarboxy acid type sequestrant formation, show excellent clean ability for dying dirt, and storage stability is good.
The invention provides a kind of liquid detergent composition, this liquid detergent composition is to the stimulation of skin, hair or cloth, damaging very soft, and clean ability excellence, also can not harden through repeatedly cleaning, and pungency is low, and outward appearance is good, excellent in stability.Liquid detergent composition of the present invention is for the detergency of clothing for baby, diaper, bedding etc., promptly to dying the detergency excellence of dirt.Specifically, the present invention relates to be suitable for the liquid detergent composition of fibre product, the particularly clothing of infants' wear, diaper etc., and the method for dying dirt of removing clothing.
