Description

[Technical field]

[0001] The present application relates to the cosmetic technical field.

[0002] More particularly, the invention relates to lipstick compositions comprising a mixture of volatile alkanes.

[0003] As part of this application, some definitions are provided.

[0004] An "alkane" is a saturated hydrocarbon consisting of only carbon and hydrogen atoms linked by single covalent bonds, with the general formula: n H 2n+2 It is.

[0005] A "straight chain alkane" is an alkane in which each carbon atom is bonded to a maximum of two carbon atoms.

[0006] A "branched chain alkane" is an alkane that has any carbon atom bonded to three or four carbon atoms.

[0007] "C x An "alkane" is an alkane of x carbon atoms, which may be linear or branched. For example, dodecane is C 12 It is an alkane.

[0008] Generally, a "volatile alkane mixture" is a mixture of alkanes having a flash point of less than or equal to 95° C., as measured according to the ASTM D93 standard.

[0009] In the present invention, the term "volatile alkane mixture" means an alkane mixture having a flash point of 55° C. or less, measured according to the ASTM D93 standard.

[0010] The flash point measured according to the ASTM D93 standard is called the "flash point". The unit of the flash point measured according to the ASTM D93 standard is degrees Celsius (℃). In addition, each value is obtained by a measurement method according to the ASTM D93 standard, and it may be the average value.

[0011] The term "mass percentage" refers to the ratio of the mass of a first compound to the total mass of a mixture or composition of compounds expressed as a percentage. For example, 10 grams of compound y in a mixture z with a total mass of 100 grams would be the mass percentage of y in z of 10%.

[0012] A "biogenic" compound or organic composition is one in which the organic carbon present in the compound or composition is 100% plant-derived (as determined by radiocarbon analysis according to any of the following standards: ASTM D6866, EN 16640, or EN 16785-1). 14 C) is defined as being.

[0013] The "naturalness index" of an organic composition is the percentage of organic carbon of plant origin ( 14 C) percentage.

[0014] In the present invention, the OECD 301F method can assess the biodegradability of a substance by a manometric respiration test.

[0015] Since isododecane was introduced into cosmetics in the 1990s, its use has expanded significantly in all areas of cosmetics, from skin care products, to makeup products such as mascara compositions and long-wearing lipsticks, and hair care products such as serums and anti-frizz dry oils.

[0016] In some of these products, isododecane constitutes up to 60% by weight of the cosmetic formulation composition.

[0017] Long-lasting make-up products currently account for approximately 25% of the global make-up market. Isododecane is the key ingredient that provides long-lasting, transfer-free and water-resistant properties while maintaining optimal comfort. This market developed from an essential ingredient, Isododecane, which is derived from petrochemicals.

[0018] However, with limited petroleum resources and a fluctuating and polluting petroleum market, meeting the demand for isododecane, or at least being able to provide equivalent properties in cosmetic formulations, has become a strategic challenge for the cosmetics industry.

[0019] The first approach to address these challenges is to develop a method for producing isododecane that does not use petroleum feedstocks.

[0020] Recently, GLOBAL BIOENEGIES Inc. disclosed in patent application WO2020188033 the production of isobutene by a biological process using genetically modified organisms such as modified E. coli.

[0021] According to patent application WO2021228824, the obtained isobutene gas is converted to isododecane by a solvent phase oligomerization reaction followed by a hydrogenation step.

[0022] This reaction, known from the chemical industry, suffers from the drawbacks of forming by-products and low yields, raising questions about the long-term viability of the approach in terms of volume and cost.

[0023] Nevertheless, GLOBAL BIOENEGIES raised more than €100 million to develop such a process between 2008 and early 2021, when it launched its first batch of cosmetic-grade isododecane.

[0024] This long-term economic investment to produce isododecane from natural feedstocks is noteworthy.

[0025] Indeed, the second strategy, reducing the amount of isododecane in current cosmetics or replacing it with another, is a challenge of an entirely different scale for the cosmetics industry.

[0026] Furthermore, as described in patent application EP3349720, finding a biodegradable alternative to isododecane would be a major advance from an environmental point of view, as such compounds could account for a mass percentage of up to 60% of a cosmetic composition.

[0027] Therefore, research was carried out to identify compounds that could be satisfactory replacements for isododecane. These compounds should have similar volatility characteristics and similar behavior in formulations, especially with regard to sensory properties such as ease of spread on skin, feel on touch, and also the "non-greasy" nature of the resulting films.

[0028] Therefore, from an economic and environmental standpoint, there is a need for cosmetic excipients that can replace isododecane as an excipient, particularly in cosmetic formulations.

[0029] Surprisingly, applicants have demonstrated that such an excipient can be obtained.

[0030] The excipient is a predefined mixture of volatile alkanes.

[0031] Preferably, the volatile alkane mixture is obtained from fatty alcohols by Guerbet alcohol reaction followed by dehydration and hydrogenation. This synthetic route advantageously makes it possible to obtain an alternative excipient to isododecane from raw materials of natural origin using an industrial process that is economically viable in relation to market needs.

[0032] Furthermore, such excipients are biodegradable according to OECD method 301F, unlike isododecane (CAS 13475-82-6).

[0033] Advantageously, the excipients of the present invention are at least 50% biodegradable according to the OECD 301F method.

[0034] The invention also demonstrates that the incorporation of this cosmetic excipient into cosmetic formulations, particularly lipsticks, long-wearing lipsticks, or lip glosses, is effective in providing the cosmetic formulations with notable cosmetic qualities such as ease of application, water resistance, good hold, and darker, brighter color, in addition to superior stability of the formulations.

[0035] Moreover, the incorporation of this cosmetic excipient makes it possible to obtain cosmetic formulations for lipsticks that exhibit a naturalness index of more than 90%.

[0036] For the purposes of the invention, the term "long-wearing" lipstick (also known as "non-transfer" lipstick) refers to a lipstick that is non-streakable, water-resistant and, in some cases, oil-resistant.

[0037] Similarly, a "lip gloss" or "lip shine" is a makeup product that adds shine and / or moisture to the lips, and sometimes adds color or shimmer to the lips. Some of these lip glosses are clear and can be applied over regular lipstick to add a glossy effect.

[0038] The invention includes a volatile alkane mixture, the volatile alkane mixture comprising: a) 20 to 100% by mass of fraction A containing at least one branched alkane of C10 or less; b) containing 0 to 80% by mass of a B fraction containing at least one linear or branched alkane above C10; The lipstick composition is characterized in that the mixture of volatile alkanes has a flash point, measured according to the ASTM D93 standard, of less than 55° C. and represents a mass percentage of at least 2% relative to the total mass of the composition.

[0039] In one embodiment, the lipstick is a non-transfer lipstick or a low transfer lipstick.

[0040] "Non-transfer lipstick" is generally defined as a product that does not risk transferring during meals or after kissing, and is an essential product that does not require reapplication during the day or at night. Non-transfer lipsticks are highly pigmented, do not leave marks, and last at least 8 hours on the lips. Thanks to fixatives, they stay clearly on the lips with less touch-ups during the day.

[0041] The invention includes a volatile alkane mixture, the volatile alkane mixture comprising: a) 20 to 100% by mass of fraction A containing at least one branched alkane of C10 or less; b) containing 0 to 80% by mass of a B fraction containing at least one linear or branched alkane above C10; The present invention relates to a composition for a non-transferable lipstick, characterized in that the volatile alkane mixture has a flash point of less than 55° C., measured according to the ASTM D93 standard, and represents a mass percentage of 25% or more relative to the total mass of the composition.

[0497] The percentages given in the table below are percentages by weight. Example 1: Lipstick formulation preparation protocol

[0498] To prepare the reference lipstick (Example 2), the prior art lipstick (Example 4) and the inventive lipsticks (Examples 6 and 7), AEROSIL was dispersed in a mixture of volatile alkanes to form the first phase of the lipstick formulation.

[0499] Once the first phase was dispersed, the second phase was weighed simultaneously in a separate vessel. The same operation was carried out with the third phase, and then the second and third phases were mixed under magnetic stirring.

[0500] The mixture of phases 2 and 3 was then placed on a hot plate and allowed to sit until the RHEOPEARL KL2 was completely dispersed.The dispersed phase 1 was then added to the mixture of phases 2 and 3.

[0501] Finally, phase 4 was heated separately on a hot plate until the wax was completely melted, after which phase 4 was cooled in a 40° C. cold water bath and added to the dispersed mixture of phases 1, 2 and 3.

[0502] Lipstick formulations of Examples 2, 4, 6 and 7 were obtained. Example 2: Composition and properties of reference lipsticks Drying time on lips of benchmark lipstick formulations [Table 1]

[0503] After application to the lips of a user panel, a test to check for dryness using a nonwoven tissue from tO to tx and a nonwoven tissue marking test were performed every 30 seconds to measure the dry time at 20° C. The formulation was considered dry when there was no transfer.

[0504] The reference lipstick obtained according to the protocol of Example 1 had a drying time on the lips of 6 minutes.

[0505] This drying time was satisfactory for a lipstick or lip gloss formulation. Application characteristics of benchmark lipstick formulations on the lips To validate this study, lipstick formulations were tested on a panel of users.

[0506] In a food situation, the benchmark lipstick held up well even though the center had disappeared (though the outline remained).

[0507] In terms of other application properties, a user panel survey showed that the benchmark lipstick had no transfer and provided good adhesion and coverage.

[0508] However, it was a little sticky. Finally, the benchmark lipstick had a satisfactory staying power of 5 hours. Example 3: Stability of the Reference Lipstick Composition of Example 2 [Table 2]

[0509] The table in Example 3a above shows the stability of the benchmark lipstick formulation as a function of temperature. The stability of this test was assessed at various time points by visual observation by an operator.

[0510] The benchmark lipstick formulation was stable at low temperatures, showing slight instability from 72 hours at 50°C.

[0511] However, this slight instability at 50° C. did not increase during the 1 and 2 week observations. [Table 3]

[0512] The table in Example 3b above shows the stability of benchmark lipstick formulations to centrifugation by visual observation by an operator.

[0513] From the results shown in Table 3b, it can be inferred that the lipstick formulation is stable to centrifugation for the speed and time of the tests performed.

[0514] From the stability results of Examples 3a and 3b, it can be inferred that the benchmark lipstick formulation exhibits sufficient stability even though slight instability may be observed during storage at elevated temperatures (50° C.). Example 4: Composition and properties of lipsticks containing volatile alkane mixtures of the prior art [Table 4]

[0515] In the composition of Example 4 of the lipstick containing a mixture of volatile alkanes of the prior art patent application EP 3 773 432 A1, the isododecane (CAS 13475-82-6) contained in the first phase of the reference formulation of Example 2 was replaced by a mixture of volatile alkanes consisting of 30% n-decane (CAS 124-18-5) and 70% n-dodecane (CAS 112-40-3). Drying time for Example 4

[0516] The lipstick of Example 4 obtained by the protocol of Example 1 had a drying time on the lips of 14 minutes.

[0517] Dry time on the lips was not satisfactory for the lipstick formulations of the present invention. Application characteristics of the formulation of Example 4

[0518] To validate this study, prior art lipstick formulations were tested on a user panel.

[0519] Thus, during meals, the prior art lipstick lasted well even though the center had worn off. However, the outline remained.

[0520] As for other application properties of the prior art lipsticks, a user panel survey showed that the prior art lipsticks were non-transferable, had average adhesion and adequate coverage.

[0521] A comparison of the prior art lipstick formulations with the reference formulation was performed on samples and evaluated by the same user panel. The prior art lipsticks were shown to have lower staying power than the reference lipsticks. However, the study also showed that the prior art lipsticks were more difficult to apply because they were more runny. Furthermore, properties such as drying time, adhesion and coverage were less satisfactory than those of the reference lipstick formulation. Example 5: Stability of the prior art lipstick composition of Example 4 [Table 5]

[0522] The table in Example 5a above shows the stability of prior art lipstick formulations as a function of temperature. Stability in this test was assessed at various time points by visual observation by an operator.

[0523] The prior art formulation was stable at low temperatures and showed slight instability from 72 hours at 50° C. However, this slight instability at 50° C. did not increase during the 1 and 2 week observations. [Table 6]

[0524] The table in Example 5b above shows the stability of prior art lipstick formulations to centrifugation by visual observation by an operator.

[0525] From the results shown in Table 5b, it can be inferred that the lipstick formulation is stable to centrifugation for the speed and time of the tests performed.

[0526] From the stability results of Examples 5a and 5b, it can be inferred that prior art lipstick formulations exhibit sufficient stability even though slight instability is observed during storage at high temperatures (50° C.). Example 6: Composition and Properties of Lipsticks of the Invention [Table 7]

[0527] In the composition of Example 6 of the inventive lipstick, the isododecane (CAS 13475-82-6) contained in the first phase of the reference formulation (Example 2) was replaced with a volatile alkane mixture as defined in the present invention, which consists of 30% 2,3,6-trimethylheptane (CAS 4032-93-3) and 70% n-dodecane (CAS 112-40-3).

[0528] Drying time of the formulation of Example 6

[0529] The lipstick of Example 6 obtained by the protocol of Example 1 had a drying time on the lips of 7 minutes.

[0530] Dry time on the lips was satisfactory for a lipstick or lip gloss formulation.

[0531] Application characteristics of the formulation of Example 6

[0532] To validate this study, lipstick formulations were tested on a panel of users.

[0533] The lipstick of Example 6 provided satisfactory staying power for 5 hours.

[0534] Furthermore, in a meal situation, the lipstick of Example 6 lasted well even though the center had worn off, however the outline remained.

[0535] In terms of other application properties, a user panel survey showed that it had no color transfer, good adhesion and good coverage.

[0536] A comparison of the inventive lipstick formulation with the benchmark formulation was performed on samples and evaluated by the same panel of users. The inventive lipstick formulation was shown to have stronger color development, specifically, it was brighter and therefore less dull than the benchmark formulation.

[0537] Comparison photographs taken during the study show the difference in light intensity. In terms of application, a user panel study showed that the inventive lipstick had similar leveling effect, coverage and staying power as the benchmark lipstick. Example 7: Stability of the lipstick composition (of the present invention) of Example 6 [Table 8]

[0538] The table in Example 7a above summarizes the stability data for lipstick formulations of the present invention as a function of temperature, which was assessed at various time points by visual observation by an operator.

[0539] The formulation of the present invention, unlike the benchmark formulation of Example 2, was stable during storage at both 4°C and 50°C. [Table 9]

[0540] The table in Example 7b above summarizes data regarding the stability of lipstick formulations of the present invention during centrifugation as assessed by visual observation by an operator.

[0541] From the results shown in Table 7b, it can be inferred that this lipstick formulation is stable to centrifugation at the speeds and times of testing performed. From the stability results of Examples 7a and 7b, it can be inferred that the lipstick formulations of the present invention have satisfactory or even better stability at elevated temperatures than the benchmark lipstick formulation of Example 2. Example 8: Composition and properties of inventive lipstick [Table 10]

[0542] In the composition of inventive lipstick Example 8, the isododecane (CAS 13475-82-6) contained in the first and second phases of the reference formulation (Example 2) was replaced with a mixture of volatile alkanes as defined in the present invention.

[0543] In this example, the mixture of volatile alkanes contained in the first phase consists of 35% 2,3,6-trimethylheptane (CAS 4032-93-3) and 65% n-dodecane (CAS 112-40-3).

[0544] In this example, a Bentone gel was prepared containing disteardimonium hectorite and triethyl citrate in the second phase using a volatile alkane mixture of the invention in place of isododecane.

[0545] In this example, the Bentone gel contains a mixture of volatile alkanes consisting of 15% 2,3,6-trimethylheptane (CAS 4032-93-3) and 85% n-dodecane (CAS 112-40-3). Drying time of formulation of Example 8

[0546] The lipstick of Example 8 obtained by the protocol of Example 1 had a drying time on the lips of 5 minutes.

[0547] Dry time on the lips was satisfactory for a lipstick or lip gloss formulation. Application characteristics of the formulation of Example 8

[0548] To validate this study, lipstick formulations were tested on a panel of users.

[0549] The lipstick of Example 8 provided satisfactory staying power for 6 hours.

[0550] Additionally, in a meal situation, the lipstick of Example 8 had good staying power.

[0551] In terms of other application properties, a user panel survey showed that it had no color transfer, good adhesion and good coverage.

[0552] A comparison of the inventive lipstick formulation with the benchmark formulation was performed on samples and evaluated by the same panel of users. The inventive lipstick formulation was shown to have stronger color development, specifically, it was brighter and therefore less dull than the benchmark formulation.

[0553] Comparison photographs taken during the study show the difference in light intensity.

[0554] In terms of application, a user panel study showed that the inventive lipstick had similar leveling effect, coverage and staying power as the benchmark lipstick. Example 9: Lip gloss composition of the present invention

[0555] The procedure for formulating a lip gloss composition according to the present invention is as follows.

[0556] The pigments of the first phase were mixed with octyldodecanol to obtain a paste. Next, the Benton gel obtained by combining the volatile alkane mixture of the present invention, stearalkonium bentonite, and triethyl citrate was added. Finally, the entire first phase was dispersed.

[0557] In this embodiment, the mixture of volatile alkanes, as defined herein, constitutes 80% or more by weight based on the total weight of the Bentone gel composition.

[0558] In the second step, the second phase of the composition of Example 10 was placed in a water bath at a temperature of 80° C. until the wax was in a liquid state.

[0559] Phase 2 was cooled to 40° C. and mixed with phase 1. [Table 11]

[0560] For the purposes of this example, the volatile alkane mixture consists of 20% 2,3,6-trimethylheptane (CAS 4032-93-3) and 80% n-dodecane (CAS 112-40-3).

[0561] The lip gloss composition of Example 9 had a viscosity of 2293 cSt at 40°C.

[0562] The lip gloss composition of Example 9 had a satisfactory shine effect. Example 10: Composition of an inventive lipstick with a high naturalness index

[0563] To prepare the inventive lipsticks of Examples 10 and 11, the first phase was dispersed with a Turax.

[0564] Once phase 1 was dispersed, phase 2 was weighed into a separate container and shaken separately with the Turax. This second phase was then added to the dispersed phase 1 and mixed with the Turax. Phase 3 was added after weighing. Phase 1, phase 2 and phase 3 were mixed with the Turax.

[0565] Phases 4 and 5 were weighed into a sealed glass container and heated with moderate stirring until the wax was completely melted. Phases 4 and 5 were cooled to 40° C. and then mixed with the other phases 1, 2 and 3.

[0566] Finally, phase 6 was weighed and added to the other phases (1, 2, 3, 4, and 5). The mixture was stirred with a Turax. The formulation was then cooled to room temperature.

[0567] The composition of an inventive lipstick formulation having a high naturalness index is as follows: [Table 12]

[0568] In the composition of Example 10, the inventive lipstick is comprised of 35% 2,3,6-trimethylheptane (CAS 4032-93-3), 15% isododecane (CAS 13475-82-6) and 50% n-dodecane (CAS 112-40-3). Contains a mixture of volatile alkanes.

[0569] Interestingly, when the mass percentage of isododecane (CAS 13475-82-6) relative to the total mass of the volatile mixture of alkanes of the invention is 15%, the inventive lipstick of Example 10 has a naturalness index of 85% according to the ASTM D6866 standard. Example 11: Composition of an inventive lipstick with a high naturalness index

[0570] This formulation was prepared following a similar protocol as shown in the previous example.

[0571] The composition of the inventive lipstick having a high naturalness index is as follows: [Table 13]

[0572] In the composition of Example 11, the inventive lipstick is composed of 35% 2,3,6-trimethylheptane (CAS 4032-93-3), 15% isododecane (CAS 13475-82-6) and 50% n-dodecane (CAS 112-40-3). Contains a mixture of volatile alkanes.

[0573] In this example, the trimethylsiloxysilicate component in the first phase of Example 11 was replaced by adjusting the bio-based component of the formulation.

[0574] Interestingly, when the mass percentage of isododecane (CAS 13475-82-6) relative to the total mass of the volatile alkane mixture of the invention is 15%, the inventive lipstick has a naturalness index of 90% according to the ASTM D6866 standard. Example 12: Biodegradability of the Volatile Alkane Mixtures Used in the Lipstick Composition of the Invention

[0575] The biodegradability of the volatile alkane mixture used in the lipstick composition of the invention was measured according to OECD method 301F. For comparison, the decomposition of isododecane (CAS 13475-82-6) was also measured by the same method. [Table 14]

[0576] The OECD 301F method allows the ease of biodegradation of a substance to be characterized by a manometric respirometry test.

[0577] The mixture of volatile alkanes tested was 58% biodegradable according to the OECD 301F method, whereas isododecane (CAS 13475-82-6) was not biodegradable according to this method.
