Description

[Technical Field]

[0001] The present invention relates to a composition for treating keratin fibers such as hair, and a method relating to the composition. [Background technology]

[0002] In the field of hair beauty treatments, it is desirable for the texture of a cosmetic composition to change during application to the hair, as this can provide a more pleasant user experience.

[0003] Examples of cosmetic compositions that can achieve such texture changes during application may be based on solid fatty substances such as solid oils that can melt during application. However, it is often difficult to reduce the inherent stickiness of solid fatty substances to an acceptable level during application.

[0004] Another example of achieving texture variation can be based on a so-called solid emulsion, which contains an aqueous dispersed phase in a solid fatty substance as a continuous fatty phase. However, preparing such a solid emulsion is difficult without careful consideration.

[0005] WO2021 / 120084 discloses a solid composition in the form of a water-on-water emulsion for makeup and / or skin care. The solid composition disclosed in WO2021 / 120084 is applied to the skin. [Prior art documents] [Patent Documents]

[0023] The fatty phase in the composition according to the present invention may further include (a-iv) at least one non-silicone oil, preferably selected from ester oils, hydrocarbon oils, and mixtures thereof, and more preferably selected from mixtures of ester oils and hydrocarbon oils.

[0024] The present invention also provides a method for treating keratin fibers such as hair, (1) A step of applying the composition according to the present invention to keratin fibers, (2) Optionally, a step of rinsing keratin fibers, and (3) Optional: A process to dry the keratin fibers. This also includes methods. [Modes for carrying out the invention]

[0025] As a result of diligent research, the inventors have found that it is possible to provide a solid composition that, when applied to keratin fibers, provides keratin fibers with advantageous cosmetic effects such as sufficient smoothness, tangle removal / combing, and flexibility of the keratin fibers, while reducing the inherent stickiness of the solid composition to at least a cosmetically acceptable level.

[0026] Therefore, the present invention is (a) (ai) at least one type of first wax, (a-ii) at least one second type of wax, and (a-iii) At least one silicone oil having a viscosity greater than 10 cst at 25°C The adipose phase including; and (b) (bi) at least one polyol, and (b-ii) Water Multiple aqueous phases including Includes, The first wax was selected from waxes of natural origin. The second wax was selected from synthetic waxes. This invention relates to a solid composition for keratin fibers such as hair, preferably a solid cosmetic composition, in which an aqueous phase is dispersed in a fatty phase.

[0027] Here, "keratin fiber" refers to a fiber containing at least one type of keratin substance. Preferably, at least a portion of the surface of the keratin fiber is formed by the keratin substance. Examples of keratin fibers include hair, eyebrows, eyelashes, etc. The composition according to the present invention is preferably used for treating hair.

[0028] The composition according to the present invention may also be in the form of a W / O type emulsion.

[0029] When the composition according to the present invention is applied to keratin fibers such as hair, the inherent stickiness of the composition according to the present invention can be reduced to at least a cosmetically acceptable level. Therefore, it is possible to change the texture of the composition according to the present invention when it is applied to keratin fibers. When applied to keratin fibers, it is preferable that the inherent stickiness of the composition according to the present invention can be reduced to the point where the stickiness is not perceived at all or is almost imperceptible. The composition according to the present invention can be easily applied to keratin fibers because, despite having a fatty phase on the outside, the inherent stickiness derived from the fatty phase on the outside can be reduced.

[0030] The composition according to the present invention can provide advantageous cosmetic effects, such as conditioning effects, to keratin fibers such as hair. The cosmetic effects provided by the composition according to the present invention may be expressed, for example, by smoothness of the hair and / or ease of detangling or combing, and / or flexibility of the keratin fibers. Therefore, the composition according to the present invention can provide keratin fibers with sufficient smoothness of the hair, detangling / combing, and / or flexibility.

[0031] The compositions according to the present invention are stable. They do not undergo phase separation even at high temperatures over extended periods. Therefore, the compositions according to the present invention appear uniform and maintain a uniform appearance.

[0032] The present invention will be described in detail below.

[0033] [Composition] One aspect of the present invention is, (a) (ai) at least one type of first wax, (a-ii) at least one second type of wax, and (a-iii) At least one silicone oil having a viscosity greater than 10 cst at 25°C The adipose phase including; and (b) (bi) at least one polyol, and (b-ii) Water Multiple aqueous phases including Includes, The first wax was selected from waxes of natural origin. The second wax was selected from synthetic waxes. This invention relates to a solid composition for keratin fibers such as hair, preferably a solid cosmetic composition, in which an aqueous phase is dispersed in a fatty phase.

[0034] The term "solid" here refers to the state under room temperature (25°C) and atmospheric pressure (760 mmHg). Solid compositions have high viscosity and can maintain their form during storage. In contrast to "fluid" compositions, solid compositions do not flow due to their own weight. For example, a solid composition remains unfluid after one hour under its own weight at room temperature and atmospheric pressure.

[0035] A "solid" can be defined as a material in which the maximum force measured by texturerometry upon insertion of the probe into the compound sample is equal to at least 0.25 Newtons, particularly at least 0.30 Newtons, and especially at least 0.35 Newtons, as evaluated under the following specific measurement conditions:

[0036] While the mixture is still hot, pour it into a jar with a diameter of 4 cm and a depth of 3 cm. Allow it to cool at room temperature. The hardness of the prepared mixture is measured after a 24-hour waiting period. The jar containing the sample is characterized by texturerometry using a texturerometer such as the TA-XT2 sold by Rheo, according to the following protocol: A 5 mm diameter stainless steel ball-type probe is brought into contact with the sample at a speed of 1 mm / second. The measurement system detects the interface with the sample with a detection threshold equal to 0.005 Newtons. The probe is inserted into the sample by 0.3 mm at a speed of 0.1 mm / second. The measuring instrument records the change in force measured during compression over time during the insertion phase. The hardness of the sample corresponds to the average of the maximum force detected during insertion over at least three measurements.

[0037] {fat phase} The fatty phase in the composition according to the present invention is (ai) at least one type of first wax, (a-ii) at least one second type of wax, and (a-iii) At least one silicone oil having a viscosity greater than 10 cst at 25°C Includes.

[0038] (ai) The first wax and (a-ii) the second wax are different from each other.

[0039] The term "wax" here refers to lipophilic compounds (especially wax esters: higher fatty acids (C) 10 The above, preferably C 12 This refers to esters of (or higher) and higher alcohols (C8 or higher), and such compounds, with the exception of jojoba oil, are solid at room temperature (25°C), reversibly change between solid and liquid states, and have a melting point of 30°C or higher, preferably 40°C or higher, more preferably 50°C or higher, and the melting point may be up to 100°C.

[0040] In this invention, the melting point is measured, for example, according to ASTM D127.

[0041] The (ai) first wax and (a-ii) second wax used in the composition according to the present invention may have a melting point of 60°C or higher, preferably 65°C or higher, and more preferably 75°C or higher. The (ai) first wax and (a-ii) second wax used in the composition according to the present invention may have a melting point of up to 90°C, preferably up to 85°C.

[0042] (ai) The first wax and / or (a-ii) the second wax may have a hardness greater than 5 MPa, particularly in the range of 5 to 15 MPa, at 20°C.

[0043] The hardness of the wax can be determined by measuring the compressive force, and is measured at 20°C using a texturerometer sold by Rheo under the name TA-XT2 (equipped with a 2mm diameter stainless steel cylinder that moves at a measuring speed of 0.1mm / second and penetrates the wax to a needle depth of 0.3mm).

[0044] The hardness measurement protocol is as follows:

[0045] The wax is melted at a temperature equal to its melting point + 10°C. The melted wax is poured into a container with a diameter of 25 mm and a depth of 20 mm. The wax is recrystallized at room temperature (25°C) for 24 hours until the surface of the wax is flat and smooth, and then the wax is stored at 20°C for at least 1 hour before measuring its hardness or tackiness.

[0046] Move the texturerometer spindle at a speed of 0.1 mm / second, then insert it into the wax to a needle insertion depth of 0.3 mm. Once the spindle is inserted to a depth of 0.3 mm, hold the spindle still for 1 second (corresponding to a relaxation time), then withdraw it at a speed of 0.5 mm / second.

[0047] The hardness value is calculated by dividing the measured maximum compressive force by the area of ​​contact between the texturerometer cylinder and the wax.

[0048] The amount of fatty phase in the composition according to the present invention may be 20% by mass or more, preferably 25% by mass or more, and more preferably 30% by mass or more, based on the total mass of the composition.

[0049] On the other hand, the amount of fatty phase in the composition according to the present invention may be 60% by mass or less, preferably 55% by mass or less, and more preferably 50% by mass or less, based on the total mass of the composition.

[0050] Therefore, the amount of fatty phase in the composition according to the present invention may be within the range of 20% to 60% by mass, preferably 25% to 55% by mass, and more preferably 30% to 50% by mass, based on the total mass of the composition.

[0051] (First wax) The composition according to the present invention comprises (ai) at least one first wax. A single type of first wax may be used, or two or more different types of first waxes may be used in combination.

[0052] (ai) The first wax is selected from waxes of natural origin. In other words, (ai) the first wax is a natural wax.

[0053] Examples of natural waxes include petroleum waxes, plant waxes, and animal waxes.

[0054] Examples of petroleum waxes include paraffin wax, microcrystalline wax, and petrolatum.

[0055] Examples of plant waxes include jojoba esters, rice wax, carnauba wax, candelilla wax, auriculy wax, wood wax, cocoa butter, cork fiber wax, and sugarcane wax.

[0056] Examples of animal waxes include lanolin wax, lanolin derivatives, and beeswax.

[0057] (ai) The first wax is preferably a jojoba ester.

[0058] Jojoba esters are given by formula (I): R 1 -COO-CH2R 1 (I) (In the formula, R 1 is CH3(CH2) y (Includes -, where y is 16, 18, 20, or 22) It can be represented by...

[0059] Jojoba esters (wax) are given by the following formula (II): CH3-(CH2)7-CH=CH-CH2-(CH2) x -C(=O)-O-CH2-(CH2) y -CH=CH-(CH2)7-CH3(II) (In the equation, x and y are independently 6, 8, 10, or 12.) It can be obtained by hydrogenating jojoba oil.

[0060] Jojoba oil is composed of linear monounsaturated aliphatic alcohols and monounsaturated fatty acids. The single double bond is located midway (n-9 position) from the terminal methyl group (-CH3) of each fatty acid or alcohol chain. Therefore, from a chemical structural standpoint, jojoba oil is rather a liquid wax, composed of esters of fatty acids with an even number of carbon atoms, primarily 20 and 22 carbon atoms, and aliphatic alcohols. The resulting esters have chain lengths of 38, 40, 42, and 44 carbon atoms, with small amounts of esters with 36 and 4 carbon atoms. A typical composition of jojoba oil is described below.

[0061] [Table 1]

[0062] Jojoba oil can be derived from the seeds of the jojoba plant (Simmondsia chinensis).

[0063] In addition, jojoba esters can be obtained by transesterification of jojoba oil and hydrogenated jojoba oil.

[0064] Jojoba esters are commercially available, for example, as Jojoba Ester 70 from Vantage Specialty Ingredients, Inc.

[0065] The amount of (ai) first wax in the composition according to the present invention may be 1% by mass or more, preferably 2% by mass or more, and more preferably 3% by mass or more, based on the total mass of the composition.

[0066] The amount of (ai) first wax in the composition according to the present invention may be 15% by mass or less, preferably 10% by mass or less, and more preferably 5% by mass or less, relative to the total mass of the composition, provided that the amount of (ai) first wax is not zero.

[0067] The amount of (ai) first wax in the composition according to the present invention may be in the range of 1% to 15% by mass, preferably 2% to 10% by mass, and more preferably 3% to 5% by mass, based on the total mass of the composition.

[0068] (Second wax) The compositions according to the present invention comprise (a-ii) at least one second wax. A single type of second wax may be used, or two or more different types of second waxes may be used in combination.

[0069] (a-ii) The second wax is selected from synthetic waxes. In other words, (a-ii) the second wax is a synthetic wax.

[0070] Examples of synthetic waxes include synthetic hydrocarbon waxes and modified waxes.

[0071] Examples of synthetic hydrocarbon waxes include polyethylene wax, polypropylene wax, and Fischer-Tropsch wax.

[0072] Examples of modified waxes include paraffin wax derivatives, montan wax derivatives, and microcrystalline wax derivatives.

[0073] (a-ii) The second wax is preferably selected from synthetic hydrocarbon waxes, such as polyethylene wax, polypropylene wax, and Fischer-Tropsch wax.

[0074] Examples of polyethylene waxes include ethylene homopolymers and ethylene-alpha-olefin copolymers. Alternatively, the wax may be obtained by thermal decomposition of the copolymer. Examples of alpha-olefins include alpha-olefins having 3 to 12 carbon atoms, such as propylene, 1-butene, 1-pentene, 1-hexene, 4-methyl-1-pentene, and 1-octene.

[0075] Examples of polypropylene waxes include propylene homopolymers, ethylene-propylene copolymers (which are random or block copolymers), and propylene-alpha-olefin copolymers (excluding ethylene or propylene). Alternatively, the wax may be obtained by thermal decomposition of the copolymer. Examples of alpha-olefins include 1-butene, 1-pentene, 1-hexene, 1-heptene, 1-octene, 4-methyl-1-pentene, 1-decene, 1-dodecene, 1-tetradecene, 1-hexadecene, and 1-octadecene.

[0076] Polyethylene wax and polypropylene wax can be obtained by known methods using polymerization catalysts such as Ziegler catalysts, Ziegler-Natta catalysts, and metallocene catalysts. Polyethylene wax and polypropylene wax obtained using metallocene catalysts are particularly preferred, as these waxes have a narrower molecular weight distribution and more stable quality compared to polyethylene wax and polypropylene wax obtained using Ziegler catalysts or Ziegler-Natta catalysts.

[0077] Fischer-Tropsch wax is a synthetic hydrocarbon wax mainly containing linear hydrocarbons, and is usually obtained by reacting aqueous gas containing carbon monoxide and hydrogen as its main components with a catalyst such as cobalt, nickel, or iron at 170-250°C under pressure. Fischer-Tropsch wax is characterized by containing hydrocarbons with an odd number of carbon atoms and hydrocarbons with an even number of carbon atoms, that is, containing both hydrocarbons with an odd number of carbon atoms and hydrocarbons with an even number of carbon atoms.

[0081] The amount of the (a-ii) second wax in the composition according to the present invention may be in the range of 1% to 15% by mass, preferably 2% to 10% by mass, and more preferably 3% to 5% by mass, based on the total mass of the composition.

[0082] (Silicone oil) The compositions according to the present invention (a-iii) contain at least one silicone oil having a viscosity of more than 10 cst at 25°C. A single type of such silicone oil may be used, or two or more different types of such silicone oils may be used in combination.

[0083] Viscosity measurements are generally performed at 25°C using a Rheomat RM180 viscometer equipped with a No. 2 spindle. The measurement is performed after rotating the spindle in the composition for 10 minutes at 200 revolutions per minute (rpm) (after which stabilization of viscosity and spindle rotation speed is observed).

[0084] (a-iii) The silicone oil may have a viscosity of 100 cst or more, preferably 500 cst or more, more preferably 1,000 cst or more, more preferably 5,000 cst or more, more preferably 10,000 cst or more, more preferably 50,000 cst or more, and even more preferably 100,000 cst or more at 25°C.

The composition according to Example 3 also provided the hair with very good manageability, very good detangling / combing, and very good hair flexibility.

[0213] The composition according to Comparative Example 1, which lacked the first wax, was in the form of a W / O emulsion, but when applied to hair, it failed to reduce the inherent stickiness of the composition to an acceptable level. The composition according to Comparative Example 1 failed to provide hair with acceptable manageability, acceptable detangle / combing, and acceptable hair flexibility.

[0214] The composition in Comparative Example 2, which lacked the second wax, was not in the form of a W / O type emulsion, and therefore, its cosmetic effect could not be evaluated.

[0215] The composition according to Comparative Example 3 corresponds to the prior art disclosed in WO2021 / 120084 because the specific formulation disclosed in WO2021 / 120084 contains only a silicone oil with a viscosity of 2 cst.

[0216] The composition according to Comparative Example 3 lacked a silicone oil having a viscosity greater than 10 cst at 25°C, although it was in the form of a W / O emulsion. However, when applied to hair, it failed to reduce the inherent stickiness of the composition to an acceptable level. The composition according to Comparative Example 3 failed to provide hair with acceptable manageability, acceptable detangle / combing, and acceptable hair flexibility.
