Background technology
Cleaning compositions, especially bathroom detergent, usually with extreme pH level preparation.For example, most of detergent for water closet is extremely acid (pH < 2), has the pH of some to be less than 1.This can damage user's skin, and hard surface and pipeline.For example, detergent for water closet can not be applied for hard-surface cleaning, because they have infringement for example marmorean danger of surface.On the contrary, the inadequate viscosity of hard surface cleaner, thus can not become effective detergent for water closet.
At other extreme pH, many bathtubs and ceramic tile cleaner are shown as the extremely solution (pH > 10) of alkalescence.This also can damage user's skin.
Clean total tendency is towards the less preparation development of corrodibility, and still, challenge is to keep functional and effect.The cleaning formulation therefore, need to excellent cleaning efficacy, low smell, desirable viscosity and more moderate pH scope.
Summary of the invention
In one embodiment, the invention provides cleaning compositions, it comprises seed oil nonionogenic tenside, anion surfactant, glycol ether solvent, and following at least one: sequestrant, hydrotrote or biocide, the pH of wherein said composition is approximately 5 to approximately 9.

Or this cleaning compositions can be used for other cleaning applications.
Embodiment
Following examples are only the objects for illustrating, are not intended to limit the scope of the invention.
Embodiment 1
Exemplary cleaning compositions of the present invention contains the component shown in table 1:
Table 1
All batch of materials are all 5-9 at the pH of 25 ℃, and it demonstrates the low-down stimulation to skin, and smell gentle (low smell).
In room temperature, Natvosol is distributed in water under high stirring velocity.EDTA is added in an independent equal portions water, and be combined with described Natvosol dispersion with high stirring velocity.Remaining composition is combined with the water of other equal portions, and is under agitation added in described Natvosol/EDTA mixture, obtain cleaning compositions.
Embodiment 2
In order to determine soap dirt and the dirty removal capacity of urine, considered following test:
the testing method of soap dirt-this testing method is carried out according to ASTM D5343-06 (evaluating the standard guidance of the clean-up performance of ceramic tile cleaner).By the compound dirt that the comprises two kinds of independent pre-blends white ceramic tiles of making dirty.A kind of pre-blend is by the compositions of mixtures that synthesizes sebum, Metallic stearates, carbon black and dust.The second pre-blend is the sodium stearate of predissolve.Dirt is used brushing piece pad applicator (painting pad applicator) to apply.The substrate of making dirty is cleaned with rill hole sponge, wherein on this sponge, has applied the detergent system of test.The standard initial reflectance reading of recommendation photoelectric reflection instrument is confirmed the homogeneity applying, and make the variation of ceramic tile minimum, and susceptibility is optimum.The per-cent of the cleaning efficiency of test sanitising agent is used following formula to calculate:
% cleaning efficiency=(Rc-Rs)/(Ro-Rs) * 100
Wherein: Rc is the reflectivity after cleaning,
Ro is initial reflectance, and
Rs is the reflectivity after making dirty.
urinate dirty testing method-in room temperature is immersed in urine by the wall tile of whiteware glazing (10cm * 10cm) and iron filings over 1 month.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, then test.Dry at 50 ℃ by thering is uniform thickness and surperficial pore cellulose sponge (4.5cm * 4.5cm).Use disposable plastic pipette four (4) grams of sanitising agents to be applied to a surface for sponge, cover as much as possible this surface completely.
The sponge of processing is placed on 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 completes, the panelist through undergoing training can observe this ceramic tile by vision and evaluate cleaning efficiency.
the testing method of viscosity-this testing method is carried out according to ASTM D1200-94 (the viscosity criterion testing method of being undertaken by Ford flow cup).
Contrast cleaning compositions of the present invention contains the component shown in table 2:
Table 2 (contrast)
| Function | Title | Dosage |
| Acid | HCl(37％) | 13.5wt％ |
| Anion surfactant | Linear alkyl benzene sulfonate | 2.0wt％ |
| Nonionogenic tenside | Fatty alcohol ethoxylate | 2.0wt％ |
| Water | Water | Surplus |
The pH of said preparation is very acid, that is, lower than 2, it is very irritating, and also has strong smell.
For cleaning of the batch of material 1 from embodiment 1 and said preparation test soap dirt (Figure 1A and Fig. 2 A) and urine dirt (Figure 1B and Fig. 2 B).
Clean for soap dirt, after 30 times are cleaned, batch of material 1 has 90% cleaning efficiency, by comparison, from the batch of material of the contrast of table 2, only has 10% cleaning efficiency.
Batch of material 1 and from the batch of material of the contrast of table 2 all to urinating dirt effectively.
These results are unexpected, this be because, composition of the present invention has been brought into play effect, this is must the effective conventional knowledge of low ability contrary with pH.In fact, composition of the present invention is more general (that is, can be used for multi-usage), simultaneously less to user's stimulation.
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 apparent for those skilled in the art.Can make these changes and improvements, and not depart from the scope of claims.
In addition, each scope of recording comprises all combinations and the subrange of scope, and concrete numeral with which.In addition, by the full content of every piece of patent, patent application and the publication recording and describe herein by reference to being incorporated to the application.
