Sell.
-clay powder is mainly formed (for example, the Fe-Mg type) by metallic aluminium silicate, and it is to make from main sedimentary rock by phyllite or fibrous mineral composition.
According to the advantageous instantiation of another one, being characterized as of plant protection composition of the present invention:
-mainly have the mineral oil of paraffin feature, be that FINA company produces, with trade name Huile F 9805
The sort of mineral oil of selling,
-solid or solid fat or vaseline, be that SHELL company produces, with trade name Petrolatum S 3285
The sort of product of selling.
According to the advantageous instantiation of another one; being characterized as of plant protection composition of the present invention; rheological agent is tieed up by a kind of carboxymethyl that the thickener of plain type or one or more biopolymers form; the latter can make by fermenting in the presence of a kind of wild Xanthomonas type of micro-organisms; it is produced by RHONE-POULENC company, and with trade name RHODOPOL
Sell.
Plant protection composition of the present invention can contain:
The C of-a kind of proton solvent such as short chain

-a kind of or several surfactants, a kind of or several wetting agents, a kind of or several dispersants also have a kind of dyestuff and/or preservative and/or antioxidant and/or spices or pheromones.
The present invention will become easier to understand owing to following description; these describe some formulation examples that mainly comprise plant protection composition of the present invention; and some are for the example of usefulness relatively, and plant protection composition therefrom of the present invention as can be seen is with respect to the advantage of prior art.
Composition of the present invention is made into the form that is suitable for the consistent lubricant cream pastel of hairbrush expansion.
Prepared three kinds of compositions of the present invention, each personal A, B and C represent.
The component that is used for these preparation compositions has:
-Ethephon, with 72% the aqueous solution that density equals 1.389, it is produced by the applicant's company and with BASE A250
Trade name sell.
-mineral component is with trade name AEROSIL 200
The silica of selling,
-oils, trade name Huile9805
,
-fat, trade name are Petrolatum S 3285
Listed the ratio of the various components that are used for preparing composition A, B and C in the following table.
The table I
| The character of component | The amount of component (in gram) | ||
| Composition A | Composition BB | Composition C | |
| Ethephon(72%) | 6.95 | 6.95 | 6.95 |

Product R and G are made into the form of pasty state " semi-finished product " product.
This 25 gram product R and this 75 gram composition G are closely mixed.
So make a brown consistent lubricant cream pastel, available hairbrush launches, and contains the Ethephon of 10% percetage by weight, its 1st/4th, the Ethephon that discharges immediately, all the other 3rd/4th, the Ethephon that progressively discharges.
In following comparative example, slow release Ethephon under the situation of composition under the situation of B and C and that make by prior art and the tolerance of water being watered pouring have been measured at composition A.
1. the relevant example relatively that supplies that slowly discharges Ethephon
In order to measure slow release, the Ethephon pastel is placed in the diffusion cell that is dipped in the water.
Measure the release of Ethepon by alkali titration for the time of staying.
Used in this respect device is the borosilicate glass goods, fibrinous plastic material or rubber, and the prior water that spends mineral matter carefully cleaned.
Said device mainly comprises the diffusion cell that a Petri by polystyrene (Petri) box is formed, and the internal diameter of its bottom is 85mm, and the lid internal diameter is 90mm, and inner height equals 10mm.
Lid has the circular cavity of an about 70mm of diameter, the cavity that obtains like this a slice coton paper, diameter 125mm for example, the perforated membrane that the DURIEUX No11 type filter paper of thickness 0.16mm is made is sealed up, filter paper should have the quality of pine, can filter fast, retention is that 10 μ and calcining residue answer＜0.01%.
The bottom of being made up of the aluminium ball that thing is placed on box of filling out, the weight of filling out thing should be enough to avoid the come-up of device, and that introduces 20 gram weight just in time then in the device contains the formal expansion of 5%Ethephon pastel with conventional layer.
Each restrains composition A with 20, and B and C carry out three experiments.
Seal up with the paper film at the top of box, and device is placed in the bottom of the 1 liter beaker (internal diameter 100mm, height 140mm) of borosilicate glass system, contains the water that 500 grams have been removed mineral matter in the beaker.
In the uniform time interval, but water is stirred evenly lightly fully, takes out after 10 milliliters that accurately measure with the about 30 milliliters water dilutions of removing mineral matter; Add the color indicator of the alcohol solution of 3 bromocresol greens as equivalent point, it the pH value equal 4 near provide by yellowish to sapphire change color.
Said sample is carried out titration with the centinormal NaOH solution of having demarcated.
Check experiment is to contain 5%Ethephon but the aqueous solution pastel that can not slowly discharge, and it is applicant's product sold (omit dyestuff wherein so that titration becomes carry out easily) on market; The processing of check experiment and present composition A, B is identical with C, and regulates as measuring release Ethephon.
Record check experiment and use composition A, the result who records when B and C that is to say that record discharges the percentage of Ethephon to the functional relation (with respect to the percentage that is contained in the Ethephon total amount in the given sample) of time, its is listed in shows in the IV.
The result who writes down in the check table IV demonstrates composition A, and B and C discharge active substance with comparison according to the slower significantly speed of test, and follow can the controlled equation of motion; In other words, when careful made ground is selected the ratio of different components, can change slow dispose procedure by people's wish, the latter can continue the endless time as composition A shows.
In each experiment, can be by at composition A, under the situation of B and C and under the situation of check experiment, discharge the ratio of necessary time of 50% active biomass and come the slow dispose procedure of quantificational expression.
Experimental result and " half discharges " required time are listed in the table V.
The table V
Under selected any condition (the in vitro test method of soaking with the aqueous solution), composition of the present invention is compared with the aqueous solution formulation of prior art and is demonstrated significantly slowly releasing properties.
2. relevant to watering of water drench or the tolerance of flushing for example relatively
Under the same standard condition, two kinds of pastel that contain 5%Ethephon compare by their flushing is showed under the flowing water flow spray situations, the aqueous solution pastel that (prior art) in the middle of these pastel sold in the market by the application company is formed, and another is composition C.
The sample that about 1 gram pasty state is for experiment is deployed on the sheet glass of a slice 76 * 26mm size as far as possible regularly, and this is equivalent to every mm
20.5 milligram of sample is arranged.
The test that obtains like this places watering under the pouring of circulating water with slide in about 20 ℃ temperature, and water velocity is about 10 milliliters/second, and said test slides is to place with the position perpendicular to the about 20 ° of angles of water (flow) direction.
Measure tolerance time is flushed away situation to pastel relation.
What obtain like this results are shown in the table VI
The table VI
By these results as can be seen, under experimental condition, hydrophobic pastel of the present invention is in the aqueous gel that is better than prior art aspect the tolerance of water wash significantly.
