Description

Cleaning composition for removing odor of fabrics dried in the shade

Technical Field

The invention relates to the field of household chemicals, and discloses a cleaning product capable of removing the peculiar smell of fabrics dried in the shade in multiple effects.

Background

In rainy days in the south of China, particularly in plum rain in the middle and downstream areas of Yangtze river, unpleasant peculiar smell is easily generated when clothes are dried in the shade. At present, the odor-removing laundry detergent is on the market, but the effect is poor.

The daily chemical products are added in many times, and the market competition of the fabric care is very strong at present, especially the laundry detergent market. In order to meet the requirements of different consumers, various large brands develop laundry detergents with different concept declarations and additional functions.

We find that in rainy days in the south China, especially in plum rain in the middle and lower reaches of Yangtze river, clothes are easy to generate unpleasant peculiar smell when dried in the shade. If a fabric care product such as a laundry detergent is developed that can remove this odor and suppress its generation, it should be able to be used in a competitive market.

Heretofore, there is no laundry detergent technology that can effectively remove the odor of the drying in the shade. The invention aims to provide a technical scheme which can remove the drying odor of clothes in the shade and inhibit the generation of the drying odor in all directions, thereby solving the trouble of consumers.

For the purposes of the present invention, the following terms are defined below.

The term "about" as used herein refers to an amount, level, value, dimension, size, or amount that differs by up to 30%, 20%, or 10% as compared to the amount, level, value, dimension, size, or amount of a reference. The percentages used herein are by weight unless otherwise indicated.

Throughout the specification and claims, unless the context requires otherwise, the word "comprise", and variations such as "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.

Aiming at the problem of clothes drying in the shade and peculiar smell, the invention treats both symptoms and root causes, and creatively adopts the combination of a surfactant, a bactericide, essence, enzyme and a plant deodorant to realize unexpected technical effects. The cleaning compositions of the present invention may be applied using any carrier acceptable in the art of fabric cleaning. In a preferred embodiment, the cleaning compositions of the present invention employ an aqueous carrier. For example, the carrier is water, e.g., pure water, distilled water, deionized water, and the like.

The cleaning composition of the present invention can remove odor-causing bacteria including Oersura (ATCC19976), Staphylococcus epidermidis (ATCC12228) and Corynebacterium jejuni (ATCC43734), and has excellent detergency to further eradicate the generation of odor source.

Specifically, ① focuses on the Oersura strain with the largest influence among three strains (Oersura strain, Staphylococcus epidermidis and Corynebacterium jejuni) which are possibly metabolized to generate the dry odor, and the most effective and intuitive bacteria inhibition ring experiment is finally selected through different bacteria removal test methods (ATP simulation experiment and bacteria inhibition ring experiment), and the result shows that the bacteria removal effect of the preferred laundry detergent is obviously superior to that of a competitive product, ② uncleaned dirt on clothes is beneficial to the growth of the Oersura strain, so the improved detergency is also a means for radically treating the dry odor of the laundry detergent, and the detergency of the preferred laundry detergent screened by the formula is superior to that of the competitive product.

On the other hand, the cleaning composition of the invention can effectively prevent and reduce the perception of peculiar smell by consumers, and realize the effect of removing the peculiar smell. Meanwhile, by adding the plant smell removing agent, clothes with heavy drying peculiar smell can be effectively removed.

Specifically, ① can effectively prevent and reduce the perception of the peculiar smell of the consumers through a new generation of essence technology, and the result shows that the odor removing effect of the preferred laundry detergent is obviously superior to that of a competitive product through the cooperation test with an essence company. ② not only meets the green trend, but also can effectively remove clothes with heavy drying peculiar smell before washing and reduce the possibility of aggravating the peculiar smell after washing by adding the plant odor removing agent.

The wet towel was air dried, and 0.02 g of mold simulant (total 0.04 g) was dropped on both sides, and the samples were evaluated sequentially, and then, after rubbing, the evaluation was performed again, which is the dry-smelling evaluation result.

Reference table for mould and flavour scores:

the result of the detection

The test samples were taken, the towels were washed according to the standard washing method described above, and then the musty odor masking effect in the wet and dry towel states was evaluated, with the results shown in tables 8 to 9.

TABLE 8

Wet towel	Example 18	Example 19	Commercial products
				Intensity of musty taste	0.8	0.8	1.3
Intensity of fragrance	4.5	4.4	3.7

A commercial product is an aomiao sun de-musty laundry detergent.

The detection method comprises the following steps:

0.2 grams of a mold simulant (5 times normal dose, severe mold) was dropped on both sides of the test towel, and the test sample was then used to clean the towel according to the standard method described above.

In the towel soaking stage in water, the musty smell in the towel of the example 18 is reduced greatly, and the towel can smell a little musty smell; the musty was also much reduced in the example 20 towel and a bit of musty was likewise noticed, but less musty than the example 18 towel; no musty odor was noted in the example 21 towels. At this stage, example 21 had the best mold odor removing ability, followed by example 20 and example 18. In the towel wringing stage, no musty smell is smelled on the towels of examples 18, 20 and 21. The combination of the above two stages provides example 21 with the best mold removal.

Test example 8: detergency test

Detecting a sample: examples 18, 20 and 21, commercial products of the liquid laundry detergent for removing musty smell by using good sunlight

The detection method comprises the following steps: the detergency is tested by referring to the standard of GBT 13174-2008 determination of detergency and cyclic washing performance for dress materials.

Hard water preparation:

250mg/kg (as CaCO) is adopted for preparing the detergent solution in the washing experiment₃Denoted, the same below) hard water, Ca²⁺With Mg²⁺The molar ratio is 6:4, and the preparation method comprises the following steps: 16.70g of calcium chloride and 20.37g of magnesium chloride are weighed to prepare 10.0L of hard water, namely 1500mg/kg of hard water. When in use, 1.0L of the water is taken to be flushed to 10.0L, namely 250mg/kg of hard water.

Measurement of whiteness:

the whiteness measurement should be carried out as follows:

according to the requirements of detergent performance test, selecting the required JB series test piece variety. Cutting the dirty cloth for measurement into test pieces, respectively matching six groups with similar average blackness according to categories, if the test pieces are JB-00, 6 test pieces should be in each group, and if the test pieces are other JB types, at least 4 test pieces should be in other JB types, and simultaneously making numbering records, wherein each group of test pieces is used for the performance test of one sample.

Test pieces were stacked in a uniform manner, and the whiteness values before and after washing were intentionally read at 457nm with a whiteness meter. Measuring the whiteness value by using two song points on the front and back surfaces of the test piece (the bright points on each surface are centrosymmetric), and taking the average value of four measurements as the before-washing whiteness F1 of the test piece; the whiteness of the test piece after washing was measured at two points on each of the front and back surfaces (the two points on each surface should be centrosymmetric), and the average of the four measurements was defined as the whiteness of the test piece after washing F2.

In order to ensure the reliability of the comparative experiment results, the quantity and the variety of each group of test pieces are the same during the decontamination washing determination. When the detergency of the detergent is tested separately for different stains, each group of test pieces has at least 6 pieces. When the detergency is tested on a plurality of dirty cloths together, each dirty cloth has at least 3 pieces of test pieces, and the number of each set of test pieces is controlled within 8-12 pieces.

The washing experiment is carried out in a vertical decontamination machine, the stirring impellers, the working tank and the decontamination bathtub are numbered and fixed one by one to form a working unit before measurement, and the instrument is preheated to 30 +/-1 ℃ for a period of time. In the test, 250mg/kg of hard water (used when the test is preheated to about 30 ℃) is used for respectively preparing a test solution 1L with a certain concentration (when not particularly stated, the concentration of the standard laundry detergent and the concentration of the test solution are both not 0.2%) by using a sample and a standard laundry detergent, the test solution is poured into a corresponding decontamination bathtub, the corresponding position of the decontamination bathtub is placed, a stirring impeller is installed, and the instrument is adjusted to keep the temperature of the washing test at 30 +/-1 ℃ for the preparation of the test.

1mL of reference protease solution with a certain concentration can be added into the standard laundry detergent solution in the decontamination bathtub according to the test requirements of the sample, and the stirring is started for 30s and then stopped.

Putting the test pieces of each group for measuring whiteness into a bathtub respectively, starting stirring, keeping the stirring speed at 120r/min (angular speed of 220 pi/min), and stopping the washing process after the washing process lasts for 20 min.

Combining the test pieces in each decontamination bathtub, pouring the test pieces into an inner barrel of a rinsing device, draining the water, putting the test pieces into the rinsing device, pouring 1500mL of tap water, covering a cover, rotating an upper handle of the rod to enable the inner barrel to rotate for about 30s and then stop (the inner barrel needs to be fully rotated in the period, but the overflow of rinsing water in a container needs to be avoided due to the fact that the inner barrel rotates too fast). The rinsed water was drained off, 1500mL of tap water was added again, and the second rinsing was repeated. The rinsing water was drained off and the test pieces were dehydrated manually for 15s (rotation speed about 1800 r/min). And taking out the rinsed test piece, hanging the test piece at room temperature, and airing to measure the whiteness F2.

And calculating the whiteness difference (F2-F1) of each test piece before and after washing in a one-to-one correspondence manner, and respectively carrying out Q value detection on each group of test pieces under the condition that the confidence coefficient is 90 percent, and taking up or rejecting suspicious values. The data which is required to be discarded when each group of test pieces exceeds the limit range does not exceed one, otherwise, the group of tests is abandoned and the test needs to be repeated. After confirming the effective whiteness difference and the number n of test piecesThe detergency ratio (R) was calculated by the following formula_i)。

R_i＝Σ(F_2i-F_u)/n

The results are shown in Table 10.
