It will be explained in detail the present invention.
Specific embodiment
Compared with oil, hydrophilic fibre such as cotton has bigger affinity to water.In laundry processes, water is from fabric
Oily dirt is shifted on surface, leads to dirt " rolling "；Then dirt can easily be removed by mechanism.Polyester fiber,
Those of such as be made of the copolymer of ethylene glycol and terephthalic acid (TPA), do not have this selective affinity to water, but is thin
Aqueous.It has been observed that common laundry does not satisfactorily remove oily dirt from this fabric, because existing between the two strong
Affinity.
The present invention provides a kind of laundry pretreatment compositions, and spot can be made loose, to make it in washing process
In be easier remove.
Composition according to the present invention is aqueous.It is that composition includes a large amount of water in other words.Preferred composition has
The water of 60 weight % to 95 weight %.More preferably water of the composition with 70 to 95 weight %.The water company of being formed in the composition
Continuous water phase, and it provides the medium for being easy to be applied on spot fabric.
Composition according to the present invention
pH
The pH of composition according to the present invention is in the range of 1 to 4.In other words, composition is acid.We are
It is highly effective to mechanical grease to observe that the composition in the scope of the invention is especially.Therefore, unlike existing with higher pH
At least some of technical combinations object, pH plays an important role.
In order to provide acidity, composition according to the present invention includes one or more organic acids, is enough to make pH described
In range.Skilled addressee will appreciate that or the amounts of one or more acid necessary to reaching desired pH can be calculated.
It is preferred that the pKa of one or more organic acids is 1 to 5 at 20 DEG C.Term pKa is introduced as the acidity for indicating weak acid
Index, wherein pKa is defined as pKa=-log10Ka, wherein Ka is acidity constant.For example, the pKa of acetic acid is 0.0000158
(=10-4.8), but pKa is 4.8, is simpler expression.PKa value is smaller, and acid is stronger.
It is preferred that organic acid is oxalic acid, tannic acid, lactic acid, citric acid, glycolic, maleic acid, tartaric acid, malic acid, acetic acid
Or at least one of ethanedioic acid.
It is expected that when, by the way that the salt of acid, such as sodium citrate, and corresponding acid is added, pH can be slightly increased.Therefore,
For example, when being desired to have the composition of pH about 3.5, then this composition preferably group containing citric acid and sodium citrate
It closes.Other suitable combinations include lactic acid and sodium lactate, acetic acid and sodium acetate.PH can be by reducing acid content and adding simultaneously
Or increase corresponding salt content to increase.In this case, salt such as sodium citrate also functions as electrolyte, is highly basic and weak
The salt of acid.Therefore, in such composition, other salt are optional as the use of " electrolyte ".
The pKa value of above-mentioned most of organic acids can be found in organic or physicochemical standard textbook.For example, oneself
The pKa of diacid is 4.43, and the pKa of malic acid is that the 3.40 and pKa of citric acid is 3.08.When acid has more than one carboxyl
When, the negative logarithm of the first acidity constant, such as oxalic acid are referred to referring to for pKa.In such a situation it is preferred to which pKa value is at least
One at 20 DEG C 1 to 5 in the range of.
Total surfactant content
The total surfactant content of composition according to the present invention is 2 to 10 weight %.This means that given combination object
Present in all surface activating agent summation.Composition tool is necessary there are three types of different types of surfactant, amount
Add up to 2-10 weight %.
First kind surfactant is anionic, and the second class is ethoxylated alcohol nonionic, and third class is two
Property ionic.It is preferred that the amphoteric ion or at least one of anionic surfactant account for the 10 of total surfactant content
To 30 parts by weight.
Surfactant is necessary cleaning action.They are also because they are in the emulsified oiliness/rouge of wash conditions
Fat dirt and be necessary.

Or sebum spot.They are mainly solid in nature, and such spot usually in its conventional use process with fabric
Contact.Non-limiting example includes mechanical grease, tomato oil spot, curry in oil spot, dirty machine oil and the derivative spot of sebum.Or
Person, spot are tea stain or fruit stain.
Following specific embodiments further illustrate the present invention, however, the present invention is not limited thereto.It is mentioned that term be to wash
Known to the technical staff of clothing detergent applications.
Embodiment
Some important parameter/variables related with embodiment are summarised in table 1.
Table 1
Decontamination index (SRI)
SRI is the measurement that the spot on how many fabric is removed during washing process.The intensity of any spot can be with
By difference of the reflectometry between spot and clean cloth, the Δ Ε of every kind of spot is provided*.It is defined as Δ Ε*,
It calculates are as follows:
L*、a*And b*It is the 1976 (L of CIE measured using standard reflection meter*、a*、b*) color space coordinate.ΔΕ*It can
To be measured before and after washing spot, to provide AE* bw(before washing) and AE* aw(after washing).
Then SRI is defined as SRI=100- Δ Ε* After washing。
SRI means completely removing for spot for 100.
Completely (or original) fabric is not washed " absolute standard ".For each experiment, it refers to dirty with application
The identical piece of fabric of the fabric of stain.Therefore, it is in L*a*b*Point in color space remains unchanged.
Prepare a series of compositions.Some within the scope of the present invention, and some do not exist then.Each composition is carried out aforementioned
It tests (SRI).The concrete condition and observation result of each composition are summarised in table 2,3,4 and 5.
Embodiment 1: influence of the surfactant to greasiness removal
Table 2
It is in table 2 statistics indicate that, composition 4 according to the present invention provide by corresponding SRI value support maximum spot goes
It removes, is highest in table.Every other composition is all in addition to the present invention.
The data are also supported as pH and salt content also within the scope of the invention, between the surfactant of three types
Synergistic effect opinion.
Embodiment 2: influence of the salt to greasiness removal
Table 3
It is in table 3 statistics indicate that the increase of salt content has direct and apparent influence to greasiness removal.However, effect is in salt
The upper limit of content is gradually reduced, and the salt content is sodium chloride in the case.Embodiment 6 is except the scope of the present invention；Institute
There are other all within.
The influence of embodiment 4:pH
Table 4
Embodiment 11,12 and 13 is except the scope of the present invention.The pH of composition 10 is 3.5, and the pH of composition 11 is
4.8.But their performance does not have difference.The increase of pH reduces performance (composition 12 and 13).Therefore, according to the present invention
The pH of composition be limited to 1 to 4.
Embodiment 5: the influence of bleaching agent
Table 5
Composition 14 represents the preferred form of composition according to the present invention.Data in the table show bleaching agent (oxygen
Change property bleaching agent) effect.Composition containing bleaching agent is better than the correspondent composition without bleaching agent.Should statistics indicate that, such as
The pH of fruit composition is kept constant, and the composition containing bleaching agent removes more spots than the composition without bleaching agent.Group
Close both objects 14 and 15 within the scope of the invention, but composition 14 is better than 15.
The data also support as pH and salt content also within the scope of the invention that the surfactant of three types mixes
Close the opinion of the synergistic effect between object and bleaching agent.
