Description

[Technical field]

[0001] The present invention relates to compositions, preferably cosmetic compositions, suitable for treating the scalp and hair. [Background technology]

[0002] Keratin materials are present widely on human body surfaces, such as skin and hair.

[0003] Recently, many people have become more interested in anti-hair loss (AHL), which is one of the concerns in scalp care. Therefore, there have been significant advances in the development and commercialization of scalp care products.

[0004] For example, WO2021 / 134463 discloses a composition comprising a fatty acid-ester mixture, such as activated virgin coconut oil, and a large amount of water. The compositions disclosed in WO2021 / 134463 are useful for scalp care.

[0005] However, it has been discovered that compositions containing fatty acid-ester mixtures and large amounts of water tend to be unstable, resulting in phase separation over time, because the fatty acid-ester mixtures tend to separate from water due to their low compatibility with water. Therefore, there is room for improving the stability of the compositions disclosed in WO2021 / 134463. [Prior art documents] [Patent documents]

[0057] The medium chain fatty acid has the following formula (II): RC(O)-OH (II) (In the formula, R is a linear or branched, saturated or unsaturated C5-C 19 , preferably C7 to C 15 , more preferably C7 to C 11 R represents a hydrocarbon group, for example an alkyl group, preferably R is a linear hydrocarbon group, more preferably R is a linear alkyl group. It can be expressed as:

[0059] According to one embodiment of the present invention, the medium chain fatty acids may be used alone or in combination of two or more fatty acids, preferably in combination of at least three, four or five fatty acids.

[0060] Preferably, the medium chain fatty acid according to formula (II) is caprylic acid (C8) (also called octanoic acid), capric acid (C 10 ), lauric acid (C 12 ), myristic acid (C 14 ), palmitic acid (C 16 ), stearic acid (C 18 ) or arachidic acid (C 20 ) may be.

[0061] The medium chain fatty acids may be at least partially esterified with a polyol.

[0062] According to one embodiment of the present invention, the monoester useful as the (c2) monoester component has the following formula (III): RC(O)-OR' (III) (In the formula, R is as defined in formula (II), R' is the residue from the polyol. It may be a monoester represented by:

[0063] The polyol may contain from 2 to 20 carbon atoms, preferably from 2 to 10 carbon atoms, more preferably from 2 to 6 carbon atoms. Useful polyols may be glycerol, propylene glycol, butylene glycol, pentylene glycol, hexylene glycol, dipropylene glycol or diethylene glycol.

[0064] Preferably, in formula (III), R and R' are different from each other, and R is a linear C7-C 15 alkyl and R' represents the residue from a linear polyol containing from 2 to 6 carbon atoms.

[0065] According to one embodiment of the present invention, a medium chain fatty acid according to formula (II) is preferably used in combination with a monoester according to formula (III) to form (c) a fatty acid-ester mixture.

[0066] Preferably, the medium chain fatty acid and monoester for the (c) fatty acid-ester mixture involve the same fatty acid moiety, i.e., the medium chain fatty acid of formula (II) and the monoester of formula (III) have corresponding R groups. That is, when a medium chain fatty acid of formula (II) with heptyl as R is used, i.e., a medium chain fatty acid that is caprylic acid, then a monoester of formula (III) with heptyl as R is used, i.e., a monoester that is a monoester of caprylic acid, is used to form the (c) fatty acid-ester mixture. Also, when two or more fatty acids are used simultaneously for the (c) fatty acid-ester mixture, two or more corresponding monoesters, each having the same fatty acid moiety, are used. In other words, according to one embodiment of the present invention, the (c) fatty acid-ester mixture can be regarded as a mixture of two or more fatty acids of formula (II) and partially esterified monoesters of each fatty acid.

[0067] According to one embodiment of the present invention, the (c) fatty acid-ester mixture comprises a plurality of, for example at least three, four or five, medium-chain fatty acids of formula (II) and monoesters of formula (III) each having the same corresponding R group as the medium-chain fatty acids of formula (II). It is preferred that the same polyol is used to form the monoesters corresponding to the medium-chain fatty acid moieties. That is, for two or more monoesters of formula (III) for the (c) fatty acid-ester mixture, they have the same R' group. Above all, glycerol is particularly used to form glycerides with the various corresponding medium-chain fatty acids listed above.

[0068] According to one embodiment of the present invention, for example, the (c) fatty acid-ester mixture contains at least three fatty acids selected from the group consisting of caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid and arachidic acid, which are to be used as the (c1) fatty acid component. Meanwhile, the corresponding monoester of each fatty acid in the (c1) fatty acid component is used as the (c2) monoester component. Preferably, each monoester of the (c2) monoester component is a glyceride.

[0069] Preferably, according to one embodiment of the present invention, the (c1) fatty acid component comprises caprylic acid, capric acid and lauric acid, while the corresponding (c2) monoester component comprises caprylglyceride (also called monocaprylin), capric glyceride (also called monocaprin), and lauric glyceride (also called monolaurin).

[0070] According to one embodiment of the present invention, for example, with respect to the (c) fatty acid-ester mixture, the total amount of fatty acids in the (c1) fatty acid component and the total amount of monoesters, e.g., glycerides thereof, in the (c2) monoester component are present in a mass ratio in the range of 4:1 to 1:1, preferably 3:1 to 1:1, and more preferably 2.5:1 to 1.5:1.

[0071] According to one embodiment of the present invention, for example, the (c) fatty acid-ester mixture can be obtained by partially directly esterifying the (c1) fatty acid component with a polyol to form monoesters, to obtain a mixture of fatty acids and the corresponding monoesters as the (c2) monoester component. It is well understood that when a polyol is used, multiesters, such as diesters, triesters, etc., may ultimately be formed. Thus, the (c) fatty acid-ester mixture comprising at least three fatty acids, monoesters corresponding to at least three fatty acids, and multiesters corresponding to at least three medium-chain fatty acids, remains useful for the purposes of the present invention.

[0072] For the purposes of the present invention, the term "multi-ester" is provided to mean an ester formed from the esterification of a polyol, in which more than one hydroxyl group of the polyol molecule is esterified. Thus, a "diester" or a "triester" according to the present invention means an ester in which two or three hydroxyl groups of the polyol molecule are esterified, respectively.

[0073] For example, when glycerol is used to esterify the (c1) fatty acid component, a useful (c) fatty acid-ester mixture may include at least three fatty acids, monoesters, diesters and triesters corresponding to the at least three fatty acids. For example, a useful (c) fatty acid-ester mixture may include caprylic acid, capric acid and lauric acid as the (c1) fatty acid component, monocaprylin, monocaprin and monolaurin as the (c2) monoester component, as well as diglycerides and triglycerides of caprylic acid, capric acid and lauric acid.

[0074] When the (c) fatty acid-ester mixture also contains a multi-ester, the content of the multi-ester is not particularly limited. For example, the multi-ester can be used in an amount of up to 90 wt%, preferably 80 wt% or less, more preferably 70 wt% or less, and even more preferably 65 wt% or less in the (c) fatty acid-ester mixture.

[0075] (AVCO) According to one embodiment of the present invention, for example, the (c) fatty acid-ester mixture can be of natural origin. Among other things, coconut oil contains a wide variety of C8-C 20 It is well known to include mixtures of fatty acids, especially those having an equal number of carbon atoms.

[0076] Therefore, it is preferred that the present invention uses coconut oil or a derivative of coconut oil, such as an esterified product of coconut oil, as (c) the fatty acid-ester mixture.

[0077] Among other things, a useful derivative of coconut oil is that called Activated Virgin Coconut Oil (AVCO). Preferably, the coconut oil is esterified with glycerol. AVCO useful according to the invention may contain (c1) caprylic acid, capric acid and lauric acid as fatty acid components and (c2) monocaprylin, monocaprin and monolaurin as monoester components.

[0078] According to one embodiment of the present invention, for example, as a useful AVCO, the total amount of fatty acids in the (c1) fatty acid component and the total amount of monoglycerides in the (c2) monoester component are present in a mass ratio in the range of 4:1 to 1:1, preferably 3:1 to 1:1, and more preferably 2.5:1 to 1.5:1.

[0079] More specifically, for example, in exemplary embodiment 1 for AVCO, a useful AVCO may comprise: (c1) a fatty acid component comprising caprylic acid in an amount of 5-20 wt%, preferably 7-15 wt%, more preferably 8-10 wt%, based on the total amount of the fatty acid component; capric acid in an amount of 1-10 wt%, preferably 2-8 wt%, more preferably 4-7 wt%; and lauric acid in an amount of 20-70 wt%, preferably 30-60 wt%, more preferably 40-55 wt%; and (c2) monocaprylin in an amount of 0.5-15 wt%, preferably 1-10 wt%, more preferably 4-7 wt%, based on the total amount of the monoester component; A monoester component comprising monocaprin in an amount of 0.1 to 10 wt%, preferably 1 to 8 wt%, more preferably 3 to 5 wt%; and monolaurin in an amount of 10 to 40 wt%, preferably 15 to 35 wt%, more preferably 20 to 30 wt%.

[0080] AVCO obtained from the esterification of coconut oil may further comprise di- and triglycerides in addition to the above (c1) fatty acid components and (c2) monoester components. For example, according to one embodiment of the present invention, a useful AVCO may comprise caprylic acid, capric acid and lauric acid as (c1) fatty acid components; monocaprylin, monocaprin and monolaurin as (c2) monoester components; and optionally di- and triglycerides of caprylic acid, capric acid and lauric acid.

[0081] When the AVCO also contains a multi-ester selected from diglycerides and triglycerides, the content of the multi-ester is not particularly limited, for example in an amount of up to 90 wt%, preferably 80 wt% or less, more preferably 70 wt% or less, and even more preferably 65 wt% or less.

[0082] According to one embodiment of the present invention, for example, a useful AVCO may comprise: (c1) a fatty acid component comprising caprylic acid, capric acid and lauric acid in an amount of 5-40 wt%, preferably 10-30 wt%, more preferably 20-25 wt%; (c2) a monoester component comprising monocaprylin, monocaprin and monolaurin in an amount of 1-30 wt%, preferably 5-20 wt%, more preferably 10-15 wt%; (c3) a diester component comprising diglycerides of caprylic acid, capric acid and lauric acid in an amount of 10-50 wt%, preferably 20-45 wt%, more preferably 30-40 wt%; and (c4) a triester component comprising triglycerides of caprylic acid, capric acid and lauric acid in an amount of 10-70 wt%, preferably 15-50 wt%, more preferably 20-30 wt%.
