Description

Detergent composition for washing rough feathers

The present invention relates to washing rough feathers agent composition, this is a kind ofly to have good ester power, the good deodorization effect of taking off, and the detergent composition of the feather after the washing with good grade.

Generally, except having attached oil soluble dirts such as wax, grease, also attached dirts such as soil, sand, dust, fecaluria, blood, bacterium, insect on the rough feathers of wild duck, goose, tame duck, swan, chicken etc., these all are to cause malodorous reason.In order to obtain feather cushion, bed clothes, feather pillow, the feather that down jackets etc. use must attach these clean removing of dirt on rough feathers, if these dirts can not fully be removed, stench will take place so that reduce commodity value.

Attach at the dirt on the rough feathers in dry dedusting operation, remove dirt settlings such as soil, sand, dust after, in washing step, do the wash and remove dirt.The washing composition that uses in the washing step requires good ester power and the deodorizing effect of taking off, if the effect of this respect is bad, stink can stay and impair commodity value in the feather.Be used to remove the washing composition of these dirts, the mixture (special public clear 51-22087 communique) of mixture (spy opens clear 55-26226 communique), sulfonated and the alkylbenzene sulfonate and the ethylene oxide family ethers tween of sulfonated and higher alcohols or alkylphenol ethylene oxide adduct etc. is for example arranged.

Mix like this and use specific anion surfactant and tween, can not obtain good effect, improve detergent concentration if expect good degreasing and deodorizing effect, feather fat is removed too much and dry and select in the operation damage feather so that reduce commodity value.In addition, in the prior art, after cleaning, also need to carry out mellowing.Desirable with washing composition as feather is degreasing power and deodorizing effect is good and do not damage its grade under common detergent concentration, and the washing composition that satisfies this requirement also fails to obtain so far.

The present inventor is good and carried out wholwe-hearted research without detriment to the rough feathers of grade with detergent composition in order to obtain degreasing power and deodorizing effect, found that the alkyl amine oxide that contains specified proportion and the composition of anion surfactant have the good washing effect.

Promptly the invention provides a kind of rough feathers detergent composition, it is characterized in that, must composition be alkyl amine oxide (A) and the anion surfactant (B) with general formula (1) expression, (A) composition be A/B=20/80～80/20 with (B) weight ratio of composition.

（1）

(in the formula, R ₁Be that carbon number is 10～20 alkyl or alkenyl, R ₂, R ₃Be that carbon number is 1～3 alkyl.）

The alkyl amine oxide of general formula (1) expression can make its oxidation with corresponding tertiary amine, among the present invention is to make it that oxidizing reaction take place with aqueous hydrogen peroxide solution to obtain oxide compound.

As the alkyl amine oxide of (A) composition, can dimethyl lauryl amine oxide compound be shown example, diethyl lauryl amine oxide compound, dimethyl palm alkyl amine oxide, dimethyl coconut alkyl amine oxide, dimethyl stearic acid alkyl amine oxide etc.

The anion surfactant of using among the present invention (B) is not particularly limited, but can following material be shown example.

1) have the alkyl of carbonatoms average out to 10 to 20 or the alkyl or the alkenyl sulfate of alkenyl,

2) have the straight or branched alkylbenzene sulfonate of carbonatoms average out to 10～16 alkyl,

3) have the straight or branched alkyl or the alkenyl of carbonatoms average out to 10～20, and contain the alkyl or the alkenyloxy vitriol of average 0.5～0.8 mole ethylene oxide at 1 intramolecularly,

4) in 1 molecule, have the alkene sulfonate of carbonatoms average out to 10～20,

5) in 1 molecule, have the alkane sulfonate of carbonatoms average out to 10～20,

6) in 1 molecule, have the saturated or unsaturated fatty acid salt of carbonatoms average out to 10～20,

7) have the alkyl or the alkenyl of carbonatoms average out to 10～20, and alkyl or the alkenyl ether carboxylic acid salt of in 1 molecule, containing the ratio=0.1/9.9～9.9/0.1 of the ratio=0.1/9.9～9.9/0.1 of average 0.5～8 mole epoxidized ethylene or propylene oxide or oxybutylene or ethylene oxide/propylene oxide or ethylene oxide/oxybutylene

8) alpha-sulfo-fatty acid salt or the ester represented of following formula:

Y represents the alkyl of carbonatoms 1～3 or the counter ion of above-mentioned anion surfactant in the formula, and Z represents the counter ion of above-mentioned anion surfactant.R ₄The alkyl or the alkenyl of expression carbonatoms 10～20.

In the above-mentioned eight class materials, 1), 2) and, 3), 4) and be good, best is the 1st) class.

(A) of the present invention composition and (B) usage quantity of composition be 20/80～80/20 by weight, 40/60～60/40 scope preferably.Exceed this scope and then can not obtain the good composition of degreasing and deodorizing effect.In the present composition, (A) composition and (B) total amount of composition two compositions wish that from energy-conservation viewpoint each time usage quantity is in 15～40%(weight) more than.

In addition, among the present invention, in the scope that does not influence effect of the present invention, also can cooperate washing composition to use composition always, as polyoxy allylic alkylation ether, but tweens such as polyethenoxy alkylphenols, higher aliphatic acid alkanolamide and oxyalkylene affixture thereof, sucrose fatty ester, fatty acid glycerine monobasic ester, inorganic or organic washing-assisting detergent, solvent solvation, fluorescence dye, spices, tinting material, antiredeposition agent etc.

Its Oil and Fat Content of feather of handling with the present invention's washing composition is low, and the degreasing appropriateness needn't be carried out mellowing, and can not produce foreign odor over a long time.Because it is high not damage grade thereby its practical value of feather.

Below describe the present invention in detail with embodiment, but the present invention is not subjected to the restriction of these embodiment.

Embodiment 1

Table 1 illustrates the result of the ratio washing rough feathers that changes sodium alkyl sulfate and alkyl amine oxide.What rough feathers used is middle home-made white goose feather and grey goose feather.Wash conditions is: in the 5g rough feathers, add 200ml water (bath raio 1: 40), rough feathers added the lotion 1.5% of the composition shown in the table 1 respectively, with washing machine (the smart mechanism of Japan) 60 ℃ of washings 30 minutes.Clean the back and discharge washings, add water 200ml again, 40 ℃ wash 10 minutes after, carry out 5 same operations altogether.Feather after washing 105 ℃ of dryings 2 hours, is carried out the foul smell evaluation and extracts with dichloromethane solvent in the Soxhlet extractor, measure Oil and Fat Content.

The foul smell evaluation is to be undertaken by following 4 sections by 5 syndics.

The ◎ feather is smelly hardly

Some is smelly a little for zero feather

The △ feather is smelly

X is identical with the rough feathers foul smell

The ratio of having confirmed sodium alkyl sulfate and trialkylphosphine oxide is 80/20～20/80 o'clock, has deodorizing effect, and the most significant proportional range of deodorizing effect is 60/40～40/60.
