Description

Rosemary-containing mite-removing shower gel and preparation method thereof

Technical Field

The invention relates to the technical field of daily chemical products, and particularly relates to a rosemary-containing mite-killing shower gel and a preparation method thereof.

Background

Mites are micro organisms widely existing in nature, have great harm to human bodies, are mainly parasitic on the faces and the skins of all parts of the human bodies, and can invade respiratory tracts of the human bodies to cause allergic reactions of respiratory systems. Therefore, with the improvement of living standard of people, a suitable daily chemical product for removing mites is found, and the daily chemical product has important significance for improving the body health and the life quality of people.

Rosemary (Rosmarinus officinalis L.) belongs to Rosmarinus of Labiatae, and is native to coastal countries of Mediterranean sea, and is widely cultivated in countries of the world, mainly France, Italy, Spain, etc. Rosemary was first introduced abroad by the institute of Chinese academy of sciences and Beijing plantations in the end of 1981, and the plant cultivation test was successful. At present, seeds are widely cut in the south of China and are successful. The main chemical components of the composition comprise terpenes, flavonoids, organic acids, essential oils and the like.

Rosemary has strong oxidation resistance, is a natural substance, and has good safety. The antioxidant mechanism is caused by the effects of the components of rosmanol, carnosol and rosemary dialdehyde in the rosemary extract. Compared to other artificially prepared antioxidants, rosemary is a favored target for daily chemical manufacturers due to its strong antioxidant properties (reported to be about 5 times as potent as BHT and BHA), natural non-toxicity, and wide source.

In particular, it has been found that rosemary exhibits strong anti-invasive properties against pests and emits a specific substance harmful to insects and harmless to the human body, thereby exhibiting bactericidal, acaricidal and vermicidal effects. Based on this, there are more and more manufacturers to add rosemary to the product to achieve the above effects.

However, rosemary is a complex organic substance, cannot exist uniformly and stably in a water aqua generally, and loses activity with time, particularly when being stored in a high-temperature environment, and performances of various aspects are reduced to a certain extent. Personal care products such as shower gels, which are often placed in bathrooms, are frequently exposed to hot water or water vapor. Such unstable properties shorten the shelf life of the related daily chemical products and impair their own functional characteristics.

In summary, there is a need to develop a mite-killing bath lotion containing rosemary to solve the unstable defect of the products and meet the use requirements of consumers.

Test example section

Test example 1 stability test

The test method comprises the following steps:

the rosemary-containing mite removing shower gel prepared in examples 1 to 3 and comparative examples 1 to 3 was subjected to a stability test by the following specific test method:

200g of each of the samples of examples 1 to 3 and comparative examples 1 to 3 was taken, and filled in a transparent PE bottle, and then placed in an oven at 40 ℃ for 72 hours, and then the appearance change of the sample was visually evaluated.

The results obtained are shown in Table 3.

TABLE 3 high temperature stability test of examples 1-3, comparative examples 1-3

From the stability tests in Table 3, it can be seen that the stability of examples 1-3 is significantly better than that of comparative examples 2-3, indicating that the modified polysiloxane is ideal as an adjuvant for stabilizing and dispersing rosemary and superior to the general polysiloxane.

Test example 2

The samples were subjected to mite killing and mite repelling tests. The tests were divided into two groups, the first being the mite kill and extermination tests of the newly prepared product and the second being the mite kill and extermination tests of the product after being placed in an oven at 40 ℃ for two weeks.

The test method is carried out according to the test method marked in the second part NY/T1151.2006, the experimenter takes the appointed number of test insects for the experiment, and sets a blank control substance, and the obtained results are shown in the table 4 after the experiment and statistics.

TABLE 4 Deacaricidal and Deacaricidal test results for Rosemary-containing Deacarid bath compositions of examples 1-3 and comparative examples 1-3

As can be seen from Table 4, the initial acaricidal and acaricidal rates of examples 1-3 and comparative examples 1-3 were 99.8% or more and 97.4% or more, respectively, at desirable levels, and the performances were comparable to each other; however, after one week of high temperature storage, the mite-killing and mite-removing rates of comparative examples 1-3 were significantly reduced relative to those of examples 1-3. This is because: comparative example 1 has the modified polysiloxane 2, the branched chain of which contains more ethoxy chain segments and less propoxy chain segments, which results in the decrease of intermolecular entanglement degree, so that the dispersion effect is slightly worse than that of the modified polysiloxane 1, and the performance of rosemary is also reduced slightly; the polysiloxane used in comparative example 2, which is itself a linear structure with short branches, resulted in a poorer dispersion effect, and thus the performance of rosemary was significantly reduced. In comparative example 3, the dispersion was the worst and the performance of rosemary was the worst, since it did not contain any polysiloxane-based material.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
