Description

Solid cosmetic composition

Technical Field

The present application relates to the field of cosmetics, and in particular to a solid cosmetic composition which is wholly or partly in particulate form or also called powder.

Background

This section provides background information related to the present application, which does not necessarily constitute prior art.

Solid cosmetic compositions are generally used in the form of loose or pressed powders, in particular loose or compacted foundations, face powders or eye shadows being mentioned. The function of the above-mentioned powders is mainly to provide colour, matt and smoothness, and for powders especially for facial skin, the function is mainly to improve the wear resistance of the foundation or, in addition, if used alone, the function is mainly to provide coverage (foundation).

The existing solid cosmetic composition has the following technical problems:

1. existing solid cosmetic compositions in particular have a tendency to eliminate the effect of coverage during the day, and therefore users generally need make-up during the day;

2. for low levels of oily binders (i.e. non-volatile oils) of solid cosmetic compositions, the powder of the solid cosmetic composition has the disadvantage of being uncomfortable, since it is dry. This discomfort is caused by the fact that it is not possible to introduce a high percentage of non-volatile oil into the solid cosmetic composition if it is otherwise desired to maintain the loose powder aspect or the non-greasy aspect of the solid cosmetic composition. Whereas conventional methods do not allow incorporation of binders in amounts exceeding an average of about 10wt% into the powdered phase;

3. matte eye shadow refers to a class of solid cosmetic compositions that have little gloss and no shiny effect. The use of the matte eye shadow can make eyes look natural in visual effect, not abrupt, has soft effect and is suitable for daily commuting and dressing. The commercial matte eye shadow mainly takes dry powder as main material, and forms the matte eye shadow with different skin feel and color by powder raw materials such as filling agent, metal soap, colorant and the like and matching with some oily adhesive (namely non-volatile oil). The dry powder matt eye shadow has the defects of insufficient adhesive capability, poor adhesive property, difficult coloring, non-lasting daily use cosmetic effect and the like.

Accordingly, there is a need to provide a solid cosmetic composition that meets consumer expectations in terms of both sensory aspects (i.e., fit, degree of coloration, and softness to the touch) and in terms of use experience (i.e., no discomfort and long lasting make-up).

Description of the terms

The term "solid" characterizes the state of a composition at room temperature (25 ℃) and at atmospheric pressure (760 mmHg), i.e. a composition having a high consistency, which maintains its shape during storage. In contrast to a "fluid" composition, the composition does not flow under its own weight.

The compositions of the present application are characterized by indentation measurements (compressive or penetration) to evaluate their hardness. The term "hardness" is understood to mean the maximum penetration force obtained during indentation measurements and is expressed in newtons.

The term "filler" is understood to mean particles of any shape, colorless or white, inorganic or synthetic, and insoluble in and dispersed in the composition medium, regardless of the temperature at which the composition is manufactured.

The term "pigment" is understood to mean any form of inorganic or organic particles, white or coloured, which are insoluble in the physiological medium and are intended to colour the composition.

The term "oil" refers to a water-immiscible, anhydrous compound that is liquid at room temperature (25 ℃) and at atmospheric pressure (760 mmHg). The term "non-volatile oil" refers to an oil that remains on the skin or keratin fibers at room temperature and atmospheric pressure.

The term "volatile oil" refers to any anhydrous medium capable of evaporating less than one hour upon contact with the skin or lips at room temperature and atmospheric pressure. The volatile oil is a cosmetic volatile oil which is liquid at room temperature.

The term "retroreflective particles" refers to such particles: the size, structure, and in particular the thickness of the layers forming the particles and the physical and chemical properties and surface state of the particles may be such that the particles reflect incident light. Where appropriate, the reflection may have an intensity sufficient to produce a macroscopic bright spot (i.e. a spot which is brighter than its environment by flashing) on the surface of the composition or mixture when the composition is applied to a support to be made up.

Disclosure of Invention

The appearance pairs of the matte eye shadow provided in example 1 obtained after press molding and the matte eye shadow provided in comparative example 3 obtained after press molding are shown in fig. 1. As shown in fig. 1, the colorant content in the matte eye shadow provided in example 1 is the same as that in the matte eye shadow provided in comparative example 3, but the appearance color saturation of the matte eye shadow provided in example 1 is higher and the smear is more colored. The addition of the wax can obviously improve the coloring degree of the matte eye shadow.

The matte eye shadow provided in examples 1-2 still achieved excellent adhesion with wax addition of not more than 10wt%, and significantly improved the fit and degree of coloring, and had long-lasting make-up effect. The dry feeling of the existing matte eye shadow product in use is avoided through the combination of the wax and the non-volatile oil, so that a user can directly paint the matte eye shadow by hands, make-up is easy, and the matte eye shadow can be overlapped for many times.

Unexpectedly, the matte eye shadow provided in examples 1-2 has excellent stability under severe shaking and also excellent stability during storage over a wide range of temperatures at wax addition levels of no more than 10 wt%.

TABLE 1

The matte eye shadow provided in examples 1-2 and the matte eye shadow provided in comparative examples 1-3 were subjected to hardness testing. Hardness test a physical analyzer of type ta.xt2i equipped with a stainless steel spindle in the form of a bead of diameter 5mm was used, the hardness being measured at 20 ℃ by measuring the force (compressive or penetrating force) (F) over time during the following operations, in particular:

samples placed in a small tray, which should have a minimum thickness of 3mm and should not have any visible defects: the cracks, large fragments and crushed areas are subjected to constant temperature control at 20 ℃;

the spindle is displaced at a speed of 0.1mm/s and then penetrates into the sample to a penetration depth of 300 μm. When the spindle has penetrated into the sample to a depth of 300 μm, the spindle is removed at a speed of 0.1 mm/s. During the retraction of the spindle, the force (compression force) drops greatly until it becomes 0 after time t. During operation, the spindle moved back and forth over a period of 6 seconds.

The same composition was measured 9 times at different locations evenly distributed and spaced apart in the sample, or on different samples of the same composition. The average of these 9 measurements represents the hardness of the composition with a 95wt% confidence interval. The test results are: the matte eye shadow provided in example 1 had a hardness of 0.1 newton, the matte eye shadow provided in example 2 had a hardness of 0.3 newton, the matte eye shadow provided in comparative example 1 had a hardness of 0.8 newton, the matte eye shadow provided in comparative example 2 had a hardness of 0.05 newton, and the matte eye shadow provided in comparative example 3 had a hardness of 0.008 newton.

The matte eye shadow is typically applied to the ocular skin with the aid of a fingertip applicator, and when the hardness of the matte eye shadow is in the range of 0.1 newton to 0.3 newton, it is felt, unexpectedly, that the user has a pleasant feel to the non-powdery and oily character of the matte eye shadow, and the user feels a pleasant feel after application.

Unlike conventional matte eye shadow, the matte eye shadow provided in examples 1-2 had a soft feel while adhering well to the fingertip applicators and proved to be easy to apply, and the matte eye shadow provided in examples 1-2 can make the skin matte and reduce minute color defects, make the skin tone uniform, and leave a natural looking film on the eye skin.

The matte eye shadow provided in comparative example 2 and the matte eye shadow provided in comparative example 3 all exhibited cracking after multiple applications, and the adhesion was insufficient.

The matt eye shadow provided in comparative example 1 was firm to the touch, did not adhere well to the fingertip applicator, and proved not to be easy to apply makeup.

Shock testing was performed on the matte eye shadow provided in examples 1-2 and the matte eye shadow provided in comparative examples 1-6. The vibration test uses a PSE-150A vibration instrument, the rotating speed range of the vibration instrument is 250 revolutions per minute, the test environment temperature is 25 ℃, the test time is 10 minutes, ten identical test samples are taken during the test and placed into the vibration instrument, the vibration instrument is used for simulating transportation test, the number of damaged test samples is counted after the test, and the stability of the maintenance form of the vibration instrument is judged through the proportion of the damaged test samples. The test results are shown in Table 2.

From comparison of the test results of examples 1-2 and comparative example 3 in Table 2, it can be determined that the absence of wax can make the matte eye shadow unable to maintain the morphological stability when it encounters vibration. From comparison of the test results of examples 1-2, comparative examples 1-2 and comparative examples 4-6 in Table 2, it can be judged that the absence of any one of the components phenyl trimethicone, caprylic/capric triglyceride and triglyceride (ethylhexanoic acid) ester affects the stability of the matte eye shadow upon encountering shaking.

The matte eye shadow provided in examples 1-2 and the matte eye shadow provided in comparative examples 1-6 were tested for stability at different temperatures, specifically:

-filling the sample in a colorless transparent 30mL glass container and preserving at 25 ℃,45 ℃, -10 ℃,5 ℃ for 24 hours, respectively;

after 24 hours, the samples were observed for their behaviour;

after room temperature has been restored, the sample is applied to the back of the hand in small amounts and its performance is evaluated.

The test results are: the matte eye shadow powder provided in the embodiment 1-2 is uniform, no abnormality is confirmed, and the stability is good; the matte eye shadow provided in comparative example 2 is uniform in powder, no abnormality is confirmed, and stability is good; the powder of the matte eye shadow provided in comparative examples 2-3 had a larger particle size and a distinct agglomeration was pasty; the powder of the matte eye shadow provided in comparative examples 4 to 6 showed a small amount of blocking, sticking, and the like.

The use experience test is carried out on the matte eye shadow provided in the examples 1-2 and the matte eye shadow provided in the comparative examples 1-6, 80 people are selected from 20-40 year old female volunteers by a poll method, the group A-H is divided into 8 groups, 10 people are respectively applied with makeup to each group to test different matte eye shadows, and each group evaluates the flying powder, the slag falling degree, the fitting property, the softness degree and the makeup holding effect, wherein 5 is very excellent, 4 is excellent, 3 is general, 2 is poor, and 1 is very poor. The statistical evaluation results are shown in table 3.

TABLE 3 Table 3

From the results shown in Table 3, it was confirmed that the matte eye shadow provided in examples 1-2 exhibited the best effects in terms of fly ash and residue removal, adherence, softness, and makeup retention. The matte eye shadow provided in comparative example 1 is difficult to take powder and make up due to overlarge hardness, and reduces the use experience. The matte eye shadow provided in comparative example 2 and comparative example 3 has a certain proportion of cracking phenomenon after being smeared for many times, and the use experience is reduced. Comparison of the results of examples 1-2 and comparative examples 4-6 shows that the absence of any of the components phenyl trimethicone, caprylic/capric triglyceride and tri (ethylhexanoate) reduces the use experience of matte eye shadow.
