Embodiment 1

In this embodiment, detergent formulation according to the present invention is tested to determine that namely its process removes the ability of tallow spot from cotton fabric.

End-point method detergency test

Reagent:

-CS46B (tallow, coloured) stained cloth (Testfabrics Inc.) to be punching into and to coil and transfer to 300I 96 orifice plate.

-composition A

-DL-arginine (number: 230-571-3) by Sigma catalog number 11020, EC

Program:

-the pre-rinsing of cloth (before being added to orifice plate) will be stained to remove the free spot of any remnants:

-in each hole, add 200l distilled water

-under 900rpm jolting plate 10 minutes

-remove water

Add following purging compound:

According to test mixture of the present invention:

Composition A 5mg/L 100l

Arginine diluent * 20l

Distilled water 60l

* in distilled water, the arginine of following mg/ml concentration is diluted to: 0.16,0.32,0.64,1.28,2.56,5.12 and 10.24.

Control mixture:

Composition A 5mg/L 100l

Distilled water 100l

-reactant is cultivated 1 hour while jolting under 900rpm under 22 degree.

-by adding 200l distilled water in each hole, then under 900rpm, jolting carrys out rinsing cloth in 5 minutes.Then liquid is removed.Repeat this program continuous four times.

-40 degree will be distributed under dry 3 hours

After-drying, digital scanning spot plate also measures its Δ E.This value is used to express cleaning effect and be defined as calico and the aberration stained between cloth after washing.Mathematically, Δ E is defined as:

ΔE＝[(·L) ²+(·a) ²+(·b) ²] ^1/2

Wherein L is measuring through darkness difference between washing cloth and calico; A and b is respectively measuring of redness and yellowing difference between two cloth.From this formula clearly, the value of Δ E is lower, and cloth will be whiter.About this colour examining technology, with reference to Commission International de I'Eclairage (CIE); Recommendation on Uniform Colour Spaces, colour difference equations, psychometric colour terms, supplement no.2to CIE Publication, no.15, Colormetry, Bureau Central de la CIE, Paris 1978.

Result

Cleaning effect is have expressed with the form of decontamination index (SRI) in following table:

SRI＝100-ΔE

SRI is higher, then cloth is more clean, SRI=100 (white)." decontamination " is to alleviate unit or to alleviate Index measurement.For (passing through human eye) visible effect, effective decontamination preferably by be equal to or greater than 2 alleviate units and more preferably greater than or the alleviation that equals 5 units represent.

Table 1: use the end-point method detergency test through staining cloth with the CS46B of a series of arginine concentrations process in MTS24 formula.Same 96 orifice plates carry out four replicate(determination)s abreast.Scanning board also calculates SRI value.

The result of table 1 is shown in Figure 1, and this figure is graphic representation, shows the change of average SRI with arginine concentrations of four replicate(determination) 1-4 in table 1.Error bar shows the standard deviation between four replicate(determination)s of each concentration.

These results illustrate, arginine removes CS46B spot with dose dependent fashion.

Tergotometer tests

Tergotometer (SR Laboratory Instruments) allows the convergent-divergent of relatively large agitator type washing machine to reproduce.This device is used for assessing arginine stains cloth cleaning action to the different fatty group in composition A.

Program:

The identical cloth that stains of two panels 10 × 10cm is added in each Tergotometer tank.Also the calico that do not stain of two panels 10 × 10cm is added in each Tergotometer tank to simulate typical wash load.Two kinds of diverse ways are adopted to use arginine: (i) passes through to be included in the formula containing purging compound or (ii) carried out pre-treatment with arginic solution to cloth before washing.

-containing arginic washing:

To stain in 1 liter of Tergotometer tank that cloth transfers to containing following content:

100mg/ml arginine (pH 8.0) 50ml (10mg/ml), 5ml (1mg/ml)

Composition A 0.57ml

France hard water (French Hardness) (50X) 10ml

Volume is supplied to 500ml with softening water.

Wash conditions: at 22 DEG C 1 hour

The pre-treatment of-arginine is washed:

Before transferring to the Tergotometer tank containing following content, within 5 minutes, carry out pre-treatment by immersion in the arginine/aqueous solution (pH 8.0) of 1mg/ml or 10mg/ml and stain cloth:

Composition A 0.57ml

France hard water (50X) 10ml

Volume is supplied to 500ml with softening water.

Wash conditions: at 22 DEG C 1 hour

-contrast washing:

To stain in 1 liter of Tergotometer tank that cloth transfers to containing following content:

Composition A 0.57ml

French Hardness(50X) 10ml

Volume is supplied to 500ml with softening water.

Wash conditions: at 22 DEG C 1 hour

After washing in softening water by cloth rinsing 5 × 2 minutes and air-dry overnight.

When fully dry, digital scanning carried out to cloth, measures its Δ E as previously mentioned respectively and calculate SRI.

Result

Cleaning effect is have expressed with the form of decontamination index (SRI) in following table:

SRI＝100-ΔE

SRI is higher, then cloth is more clean, SRI=100 (white).

The result of table 7 is shown in Figure 7, and this figure is bar graph, shows the change of average SRI with arginine concentrations of replicate(determination) 1-4 in table 7.Error bar shows the standard deviation between four replicate(determination)s of each concentration.

Table 8: use the Tergo-O-tometer test carried out through staining cloth with the artificial sebum of 1mg/ml and 10mg/ml arginine washing in MTS24 formula.Carry out 4 replicate(determination)s (2 replicate(determination)s of each Tergo-O-tometer tank) abreast.

The result of table 8 is shown in Figure 8, and this figure is bar graph, shows the change of average SRI with arginine concentrations of replicate(determination) 1-4 in table 8.Error bar shows the standard deviation between four replicate(determination)s of each concentration.

Conclusion:

Arginic introducing improves removing of tested fatty group spot.To be in the composition A containing tensio-active agent to carry out pre-treatment with arginine also improve decontamination to staining cloth before washing.
