Description

Cleaning compsns and method

Background technology

Cleaning compsns, especially bathroom detergent are usually with extreme pH level preparation.For example, most of detergent for water closet is a tart (pH＜2) extremely, and the pH that some are arranged is less than 1.This can damage user's skin, and hard surface and pipeline.For example, detergent for water closet can not be used for hard-surface cleaning to be used, because they have the infringement for example marmorean danger in surface.On the contrary, the not enough viscosity of hard surface cleaner, thus can not become effective detergent for water closet.

At other extreme pH, many bathtubs and ceramic tile sanitising agent are shown as the extremely solution (pH＞10) of alkalescence.This also can damage user's skin.

Total tendency of cleaning is towards the littler preparation development of corrodibility, and still, challenge is to keep functional and effectiveness.The cleaning formulation that therefore, need have superior cleaning efficacy, low smell, ideal viscosity and more moderate pH scope.

Summary of the invention

In one embodiment, the present invention provides cleaning compsns, and it comprises the seed oil nonionogenic tenside; AS; Glycol ether solvent and following at least a: sequestrant, hydrotrote or biocide, the pH of wherein said compsn are about 5 to about 9.

The pH of wherein said compsn is about 5 to about 9.Should be appreciated that for 100wt% altogether, the surplus water is supplied.

In some cases, cleaning compsns of the present invention can be used as the bathroom detergent of all purposes.In itself, they must demonstrate soap dirt, sebum dirt and urine dirt are had superior cleaning efficacy.Simultaneously, said cleaning compsns demonstrates low smell and optimum viscosity ideally.The viscosity of said optimum gives the ability that this cleaning compsns slowly moves down from vertical surface, allows less dosage.

Perhaps, this cleaning compsns can be used for other cleaning applications.

Embodiment

Following examples only are to be used for illustrative purposes, are not intended to limit scope of the present invention.

Embodiment 1

Exemplary cleaning compsns of the present invention contains the component shown in the table 1:

Table 1

All batch of materials all are 5-9 at 25 ℃ pH, and it demonstrates low-down stimulation to skin, and smell gentle (low smell).

In room temperature, Natvosol is distributed in the water under high stirring velocity.EDTA is added in the independent equal portions water, and combine with said Natvosol dispersion-s with high stirring velocity.The water of remaining composition with other equal portions is combined, and under agitation it is added in described Natvosol/EDTA mixture, obtain cleaning compsns.

Embodiment 2

In order to confirm the removal performance of soap dirt and urine dirt, considered following test:

The testing method of soap dirt-this testing method is carried out according to ASTM D5343-06 (standard of estimating the clean-up performance of ceramic tile sanitising agent instructs).With the compound dirt that the comprises two kinds of independent preparatory blends white ceramic tiles of making dirty.A kind of preparatory blend is made up of the mixture of synthetic sebum, Metallic stearates, carbon black and dust.The second preparatory blend is the StNa of predissolve.Dirt uses brushing piece pad applicator (painting pad applicator) to apply.The substrate of making dirty is cleaned with rill hole sponge, has wherein applied the detergent system of test on this sponge.Recommendation uses the standard initial reflectance reading of photoelectric reflection appearance to confirm the homogeneity that applies, and makes the minimum and susceptibility optimum of variation of ceramic tile.The per-cent of the cleaning efficiency of test sanitising agent uses computes:

The * 100 of % cleaning efficiency=(Rc-Rs)/(Ro-Rs)

Wherein: Rc is the reflectivity after the cleaning,

Ro be initial reflectance and

Rs is the reflectivity after making dirty.

The testing method of urine dirt-(10cm * 10cm) is immersed in the urine above 1 month with iron filings with the glazed wall tile of whiteware in room temperature.Rust and urine dirt deposition are on the surface of ceramic tile.From urine, take out the ceramic tile of making dirty, and make its dried overnight, test then.Pore cellulose sponge (the 4.5cm * that will have uniform thickness and surface 4.5cm) 50 ℃ of dryings.Use the disposable plastic pipette to restrain the surface that sanitising agents are applied to sponge with four (4), covering fully as much as possible should the surface.

The sponge of handling is placed on the swab (can derive from Paul N.Gardner Co., Gardner ModelAG-8100).This swab is configured such that this sponge is with consistent this ceramic tile of making dirty of applied pressure circulation process.After this circulation is accomplished, can estimate cleaning efficiency through this ceramic tile of visual observation through the panelist who undergoes training.

The testing method of viscosity-this testing method is carried out according to ASTM D1200-94 (the viscosity criterion testing method of carrying out through the Ford flow cup).

Contrast cleaning compsns of the present invention contains the component shown in the table 2:

Table 2 (contrast)

Function	Title	Dosage
			Acid	HCl(37％)	13.5wt％
AS	Linear alkyl benzene sulfonate	2.0wt％
			Nonionogenic tenside	Fatty alcohol ethoxylate	2.0wt％
Water	Water	Surplus

The pH of said preparation is unusual tart,, is lower than 2 that is, and it is very irritating, and also has strong smell.

To the cleaning of testing soap dirt (Figure 1A and Fig. 2 A) and urine dirt (Figure 1B and Fig. 2 B) from batch of material 1 and the said preparation of embodiment 1.

For the cleaning of soap dirt, after 30 times were cleaned, batch of material 1 had 90% cleaning efficiency, by comparison, only had 10% cleaning efficiency from the correlated batch of material of table 2.

Batch of material 1 and all effective to urinating dirt from the correlated batch of material of table 2.

These results are unexpected, this be because, compsn of the present invention has been brought into play effect, this and pH must hang down ability effective conventional knowledge opposite.In fact, compsn of the present invention is more general (that is, can be used for multi-usage), and is littler to user's stimulation simultaneously.

Think and the invention is not restricted to that the application is concrete to be disclosed and the embodiment of example.Various improvement of the present invention will be conspicuous to those skilled in the art.Can make these changes and improvement, and not depart from the scope of accompanying claims.

In addition, each scope of being put down in writing comprises all combinations and the subrange of scope, and concrete numeral with which.In addition, incorporate the full content of every piece of patent, patented claim and the publication putting down in writing and describe among this paper into the application through reference.
