Description

[Technical field]

[0001] The present invention relates to cleaning compositions, and in particular to cleaning compositions containing oleosomes, methods for improving the moisturizing properties of cleaning compositions, and methods for sustaining moisturizing properties after cleaning. [Background technology]

[0002] While a cleaning composition is required to have the ability to remove skin secretions such as sebum and various exogenous substances adhering to the skin, etc., and to keep the skin, etc. clean, there is a concern that, for example, the barrier function of the skin may be reduced if the sebum film and natural moisturizing factors, etc., which are responsible for the homeostasis of the skin, are also removed. Therefore, there is a demand for a cleaning composition that is excellent in moisturizing properties while sufficiently removing skin secretions, etc., that is, a cleaning composition that is excellent in the ability to give the skin, etc. a moist feeling and a moist feeling.

[0003] Meanwhile, oleosomes are known as moisturizing components that can be incorporated into topical compositions. Oleosomes are intracellular organelles isolated from cells of plants and the like, and have a capsule structure in which oil is encapsulated by a membrane made of proteins, phospholipids, and the like (Non-Patent Document 1).

[0073] Although the optional components described above can be blended into the present cleaning composition, it is preferable not to include sodium hydroxide for reasons such as the tendency of the composition to solidify in a soap-based cleaning composition when sodium hydroxide is added, and the tendency of the composition to have an alkaline pH in an amino acid-based cleaning composition, making it necessary to add another acidic component. Incidentally, "not containing sodium hydroxide" means that sodium hydroxide is not substantially contained. Specifically, it means that sodium hydroxide is not contained or, even if it is contained, it is contained in a small amount. For example, even if sodium hydroxide is contained, it is preferably less than 0.1 mass % relative to the total amount (100 mass %) of the cleaning composition, more preferably less than 0.05 mass %, even more preferably less than 0.01 mass %, and particularly preferably 0 mass %.

[0074] [viscosity] The viscosity (25° C.) of the present cleaning composition can be appropriately set depending on the formulation and the like, and is not limited, but is, for example, preferably 500 to 2,000,000 mPa·s, more preferably 700 to 1,500,000 mPa·s, and even more preferably 1,000 to 1,000,000 mPa·s.

[0075] The viscosity (25°C) is measured using a single cylindrical rotational viscometer (Brookfield viscometer) in accordance with the viscosity measurement method described in the general test method of the Japanese Pharmacopoeia, 18th Edition. Specifically, it is a value measured using a TV-10M (manufactured by Toki Sangyo Co., Ltd.), and the selection of conditions such as the rotor and rotation speed is in accordance with the instruction manual for this machine, and the viscosity is measured at 25°C.

[0076] The single cylinder rotational viscometer is described below. A single cylinder rotational viscometer is a viscometer that measures the torque when a cylinder in a liquid is rotated at a constant angular velocity. The viscosity of the liquid, η, is calculated by the following formula, by determining the device constant KB experimentally in advance using a standard liquid for calibrating the viscometer. η=KB×T / ω η: Viscosity of the liquid (mPa s) KB: Equipment constant (rad / cm 3 ) ω: Angular velocity (rad / s) T: Torque acting on the cylindrical surface (10 -7 N m)

[0078] [Dosage form / formulation] The cleaning composition is prepared in various forms by blending the above-mentioned components and, if necessary, blending further components according to a conventional method. The cleaning composition is provided in any form that can be widely used as cosmetics, quasi-drugs, medicines, etc. The cleaning composition is provided, for example, as a lotion, gel, mousse, liquid, suspension, emulsion, cream, ointment, gel, liniment, etc., but is not particularly limited thereto. The cleaning composition is provided, for example, as a body soap (also called body shampoo), hand soap, face wash, cleansing for makeup removal, hair shampoo, dry shampoo, rinse-in shampoo, etc., but is not particularly limited thereto.

[0079] [Applications, etc.] The cleaning composition of the present invention is preferably used as a cleaning composition applied to the skin (including the face, body, and scalp) and hair. In particular, it is more preferably used as a skin cleaning composition, and is particularly preferably a face and / or body cleaning composition. In addition, the cleaning composition of the present invention is also useful as a cleaning composition for sensitive skin and / or dry skin, since it has excellent moisturizing properties after cleaning. The above-mentioned "sensitive skin" refers to skin in a state where the stratum corneum is abnormal, the structure of the stratum corneum is disturbed, and the skin reacts sensitively to physical and / or chemical stimuli (sunlight, air pollution, active oxygen, chemical substances, temperature, dryness, smoking, excessive skin washing, stress, etc.) Furthermore, "dry skin" refers to skin in a dry state where the moisturizing function is reduced.

[0080] [Manufacturing method] The cleaning composition can be produced by a known method, for example, by mixing the components according to or in accordance with the General Provisions of the Japanese Pharmacopoeia, 18th Edition.

[0081] [container] The cleaning composition can be filled into a container appropriately selected according to the purpose and application of use and used. Examples of the container include bottles, tubes, jars, dispensers, pouches, and cheer packs. Examples of materials constituting the container include polyethylene terephthalate, polypropylene, polyethylene (HDPE, LDPE, LLDPE, etc.), ABS resin, ethylene vinyl alcohol resin, polystyrene, glass, and metal (aluminum, etc.), and mixtures thereof. In addition, containers formed from these materials can be subjected to various coating treatments on the container surface, for example, in consideration of strength, flexibility, weather resistance, or stability of components. In addition, the container can be formed by laminating films formed from the above materials.

[0082] (Usefulness of the cleaning composition) When a cleaning composition containing oleosome is rinsed with water during cleaning, a considerable amount of the oleosome contained therein tends to be washed away with water, so it has been difficult to find a formulation design that can fully utilize the efficacy of the oleosome. Simply adding oleosome to a cleaning composition does not fully utilize the efficacy of the oleosome, and the moisturizing property cannot be significantly improved. According to the present invention, by making the cationic polymer (B) coexist with the cleaning composition containing the oleosome (A), the residual property of the oleosome can be improved. That is, the present invention is very useful in that it can increase the ability of the oleosome to remain on the washed area such as the facial skin after rinsing with water (the residual property of the oleosome). In addition, it can be said that the coexistence of the cationic polymer (B) with the cleaning composition containing the oleosome (A) as in the present invention can improve the adsorptivity of the oleosome. In other words, it can be said that the ability of the oleosome to be adsorbed or adhered to the site to be washed, such as the skin of the face, during rinsing with water (adsorbability of the oleosome) can be improved, and in this respect, it is also very useful. The present cleaning composition has excellent oleosome retention and / or oleosome adsorption properties, thereby improving the moisturizing properties of the cleaning composition, and is excellent, for example, in that it can effectively retain a moist and moist feeling on the skin after cleaning.

[0083] Therefore, the present cleansing composition can increase the moisture content of the stratum corneum after cleansing. Specifically, the moisture content of the stratum corneum (SCI) measured by the method described in the Examples below can be increased by, for example, 15 ) can be increased, for example, by increasing the stratum corneum moisture content (SCI 15 ) can be made to be 70% or more, more preferably 72% or more, and even more preferably 75% or more.

[0084] In addition, by adding a cationic polymer (B) to a cleaning composition containing oleosome (A) as in the present invention, the moisturizing effect of the cleaning composition can be improved. In other words, the oleosomes remaining on the skin or the like have excellent moisturizing properties (moisturizing effect) because the oils stored therein are gradually released. Therefore, the cleaning composition can provide a moisturizing or moist feeling to the skin after cleaning for a long time.

[0085] Furthermore, by making the cationic polymer (B) coexist with the cleaning composition containing the oleosome (A) as in the present invention, it is possible to improve the moisturizing recovery of the skin, etc. after cleaning with the cleaning composition. That is, the oleosome remaining on the skin, etc. is very useful in that it can effectively recover the moisturizing property lost by cleaning, since the oil stored therein is gradually released. Specifically, as in the present invention, the coexistence of the cationic polymer (B) with the cleansing composition containing the oleosome (A) allows the moisture content of the cleansed area, which has been reduced by cleansing, to be quickly restored. Specifically, the present invention is very useful in that it can accelerate the rate at which the moisture content of the stratum corneum of the skin, which has been reduced by cleansing, is increased. More specifically, the stratum corneum moisture recovery (SCI) measured by the method described in the Examples below R ) can be increased, and as an example, the stratum corneum moisture recovery (SCI R ) can be made to be 3.6 or more, more preferably 5.0 or more, even more preferably 5.5 or more, and particularly preferably 6.0 or more.

[0086] <Moisturizing cleansing composition, etc.> As described above, the present cleaning composition has excellent moisturizing properties after cleaning, and therefore, as one embodiment of the present invention, it is suitable as a moisturizing cleaning composition containing (A) oleosomes and (B) a cationic polymer. The present invention is also suitable as a moisture retention enhancer containing (A) oleosome and (B) cationic polymer, particularly as a moisture retention enhancer that enhances the moisture retention of (A) oleosome.

[0087] <Method for improving moisturizing properties of cleaning composition> In addition, as one embodiment of the present invention, the present invention is also suitable as a method for improving moisturizing properties of a cleaning composition containing (A) oleosome by coexisting with (B) cationic polymer. The present invention is also suitable as a method for improving moisturizing recovery of skin, etc., after cleaning with a cleaning composition containing (A) oleosome by coexisting with (B) cationic polymer. The present invention is also suitable as a method for accelerating the speed at which the stratum corneum moisture content of the skin, which has decreased due to cleaning, is restored or increased, using a cleaning composition containing (A) oleosome and (B) cationic polymer. Furthermore, the present invention is also suitable as a method for maintaining moisturizing properties of skin, etc., after cleaning, by applying a cleaning composition containing (A) oleosome and (B) cationic polymer to the skin. In particular, the present invention is suitable as a method for maintaining moisturizing properties of skin after cleaning, by lathering a cleaning composition containing (A) oleosome and (B) cationic polymer, applying the same to the skin, and rinsing the same.

[0088] In addition, as one embodiment of the present invention, the coexistence of (A) oleosome and (B) cationic polymer is also suitable as a method for improving the retention of oleosome or a method for improving the adsorption of oleosome. EXAMPLES

[0089] The present invention will be described in more detail below, but the present invention is not limited thereto. The content units in Tables 1 and 2 and each formulation example showing the examples are mass% and are all values ​​converted into pure content. The total amount of each composition is 100 mass%. The pH measurement temperature in Tables 1 and 2 and each formulation example showing the examples is 23°C.

[0090] <Test 1: Evaluation of residual amount of oleosomes after washing> Cleansing compositions (Examples 1 to 5, Comparative Examples 1 to 11, and control) having the formulations shown in Table 1 below were prepared by a conventional method, and the amount of residual oleosome was evaluated according to the following method.

[0091] [Method for measuring residual protein amount] 1 mL of the cleaning composition was added to each well of a 6-well plate (AGC Technoglass, IWAKI microplate, no surface treatment), and the plate was shaken for 4 hours at 55 rpm and 25° C. using a shaker (As One, rocking mixer), and then the inside of the well was washed with ion-exchanged water. The washing process consisted of a first washing process in which 2 mL of ion-exchanged water was added to each well and mixed, and the mixed liquid in each well was discarded, and this washing process was repeated twice (second and third washing processes) in which 3 mL of ion-exchanged water was added to each well and mixed, and the mixed liquid in each well was discarded. After the washing treatment, the 6-well plate was dried with nitrogen blow, and then 0.1% SDS (sodium dodecyl sulfate) aqueous solution was added to each well, and the adsorbed components were extracted using a sonicator (Sharp Corporation, ultrasonic cleaner). In order to quantify the components derived from oleosomes, the proteins were quantified using BCA Assay (Thermo Fisher Scientific, Micro Bca Protein Assay Kit). The results are shown in Figure 1.

[0092] [Table 1]

[0093] As shown in Table 1 and Figure 1, it was confirmed that the amount of protein remaining on the skin after washing was significantly reduced in Comparative Examples 1, 10, and 11, which contained the cleaning component (C) in comparison with the control, which was a composition containing the oleosome (A). This indicates that when the skin or the like is washed with a cleaning composition containing the oleosome (A), a considerable amount of the oleosome (A) is washed away, and the amount remaining on the skin or the like is reduced.

[0094] On the other hand, it was confirmed that Example 1, which further contained (B) cationic polymer in comparison with Comparative Example 1, had a significantly increased amount of protein remaining after washing, compared with Comparative Example 1. This indicates that the coexistence of (B) cationic polymer in a cleaning composition containing (A) oleosome makes it difficult for the oleosome to be washed away, and allows the oleosome to remain predominantly on the skin, etc.

[0095] It was also confirmed from Examples 2 to 5 and Comparative Examples 2 to 9 that by adding (B) a cationic polymer to a cleaning composition containing (A) oleosomes, the oleosomes are less likely to be washed away and the oleosomes can be preferentially left on the skin, etc. That is, in Comparative Example 2, which was formulated with (C) a cleaning component and an "anionic polymer" in comparison with the control containing (A) oleosome, it was confirmed that the amount of protein remaining after washing was significantly reduced compared to the control, while in Example 2, which was further formulated with (B) a cationic polymer in comparison with the above-mentioned Comparative Example 2, it was confirmed that the amount of protein remaining after washing was significantly increased compared to Comparative Example 2.

[0096] Furthermore, in Comparative Examples 3 to 5, which were formulated with (C) a cleaning component and a "polyhydric alcohol" or "ceramide III" in comparison with the control, which was a composition containing (A) oleosome, it was confirmed that the amount of protein remaining after washing was significantly reduced compared to the control. On the other hand, in Examples 3 and 4, which were formulated with (B) a cationic polymer in addition to Comparative Examples 3 and 4, it was confirmed that the amount of protein remaining after washing was significantly increased compared to Comparative Examples 3 and 4.

[0097] Similarly, in Comparative Example 6, which was formulated with two types of (C) cleaning ingredients in comparison with the control, a composition containing (A) oleosome, it was confirmed that the amount of protein remaining after washing was significantly reduced compared to the control, while in Example 5, which was formulated with (B) cationic polymer in addition to Comparative Example 6, it was confirmed that the amount of protein remaining after washing was significantly increased compared to Comparative Example 6. Also, in Comparative Examples 7 to 9, which were formulated with an "anionic polymer" or a "polyhydric alcohol" in comparison with Comparative Example 6, it was confirmed that the amount of protein remaining after washing was significantly reduced compared to the control.

[0098] From the above, it was demonstrated that in the cleaning composition containing (A) oleosome, (B) cationic polymer acts specifically to produce the effect of allowing oleosome to remain preferentially on the skin, etc.

[0099] The reason why the coexistence of the (B) cationic polymer in a cleansing composition containing the (A) oleosome produces the effect of allowing the oleosome to remain predominantly on the skin, etc. is not necessarily clear, but the present inventors speculate that this is because the (B) cationic polymer makes it easier for the components in the (A) oleosome to be adsorbed onto the skin, preventing them from being washed away even after the cleansing step.

[0100] <Test 2: Evaluation of moisturizing properties> Next, cleaning compositions (Examples 6 to 9, Comparative Examples 12 and 13, and Reference Example) having the formulations shown in Table 2 below were prepared by a conventional method, and their moisturizing properties were evaluated as follows.

[0101] A panel of experts evaluated the moisturizing properties of each cleansing composition by comparing the moisture content of the stratum corneum before and after cleansing. Specifically, 10 expert panelists selected a 2cm x 2cm area on the inside of the upper arm, and measured the moisture content of the stratum corneum (SC) of the area using a SKICON-200EX (manufactured by IBS) according to the attached instructions. Next, 10 μL of the cleaning composition was applied to the area, and the area was rubbed with a finger, and then washed with running water (100 mL / s) at 37°C for 5 seconds. The stratum corneum moisture content (SC) of the area was measured 15 minutes after washing. 15 ), and the stratum corneum moisture content (SC) of the corresponding area 30 minutes after washing 30 ) was measured using a SKICON-200EX in the same manner as above.

[0102] [Evaluation of moisturizing effect after washing] The moisture content of the stratum corneum (SC) before washing was taken as the standard (100%), and the moisture content of the stratum corneum (SC) 15 minutes after washing was taken as the standard (100%). 15 ) is the index of stratum corneum moisture content (SCI 15 The stratum corneum moisture content (SCI 15 The results are shown in Table 2. 5. Moisture content of the stratum corneum after washing (SCI 15 ) is over 80%. 4. Moisture content of the stratum corneum after washing (SCI 15 ) is between 75% and 80%. 3.

[0104] [Table 2]

[0105] As shown in Table 2, it was confirmed that Examples 6 to 9, which contained a cationic polymer (B) in addition to a cleaning composition containing (A) oleosome, were excellent in both moisturizing properties and moisturizing recovery properties after cleaning. The results of FIG. 1 and Table 2 show that by coexisting (B) a cationic polymer in (A) a cleaning composition containing oleosomes, the oleosomes are less likely to be washed away and can be allowed to remain predominantly on the skin, etc., thereby improving the moisturizing properties and moisturizing recovery properties after cleaning.

[0106] In addition, it was also confirmed that when a cationic polysaccharide such as polyquaternium-10 or guar hydroxypropyltrimonium chloride was used as the cationic polymer (B) as in Examples 6 to 8, or a synthetic cationic polymer containing dimethyldiallylammonium chloride such as polyquaternium-7 was used, the moisturizing recovery after washing was particularly excellent.

[0107] On the other hand, it was confirmed that Comparative Example 12, which does not contain the cationic polymer (B), has poor moisturizing properties and moisturizing recovery properties after washing. The results of Fig. 1 and Table 2 show that when the cationic polymer (B) is not coexisted, the oleosomes are easily washed away and cannot be allowed to remain predominantly on the skin, etc., resulting in insufficient moisturizing properties and moisturizing recovery properties after washing. In addition, it was confirmed that Comparative Example 13, which does not contain (A) oleosome and (B) cationic polymer, had low moisturizing properties and poor moisturizing recovery. It is presumed that in a cleaning system that does not contain (A) oleosome and (B) cationic polymer, even the moisturizing components in the stratum corneum are washed away, resulting in low moisturizing properties and moisturizing recovery after cleaning.

[0108] As described above, it has been demonstrated that by allowing the coexistence of the (B) cationic polymer in the (A) cleaning composition containing the oleosome, the oleosome can be allowed to remain predominantly on the skin, etc., and as a result, a cleaning composition having excellent moisturizing properties and moisturizing recovery properties after cleaning can be provided.
