Description

2-PHASE SILICONE SPRAY CONDITIONER

Technical Field

[1] The application describes hair treatment compositions with two superimposed layers and a common interface, containing a water phase and a specific mixture of silicones in an oil phase.

[2] The application further describes a method of conditioning hair using the hair treatment compositions and the use of the hair treatment compositions to improve specific conditioning properties of hair.

Background

[3] Two-phase hair conditioners have long been known from the state of the art and are highly appreciated by consumers for their attractive appearance and ease of use. Typically, these are leave-on products that are preferably applied to the hair (preferably sprayed) immediately after the two phases have been mixed for a short time to condition the hair.

[4] In the oil phase, the vast majority of these products contain cyclic silicones [5] DE 102020202673 described the preparation of a two-phase care spray comprising a mixture of silicones -with cyclomethicone as the main component of the oil phase.

[6] Cyclomethicones have recently been classified by the European Chemicals Agency as a substance of very high concern, which is why significant amounts of cyclomethicones may no longer be used in cosmetic products in the future. However, the development of cyclomethicone-free products can present difficulties; for example, product feel and appearance can be negatively affected by the absence of cyclomethicone. The biggest difficulty in replacing cyclomethicone in cosmetic hair care products is finding conditioning agents that do not weigh hair down and make it greasy. In the special case of two-phase sprays, care must also be taken to ensure that cyclomethicone substitutes do not make the viscosity of the oil phase too high, otherwise rapid mixing and demixing of the water and oil phases cannot be guaranteed.

[7] The present application was based on the task of developing 2-layer hair care products that contain essentially no cyclic silicones. The hair care products are also said to have good stability and excellent conditioning properties.

Description

[8] It has been found that by combining certain silicones in the oil phase, two-phase hair treatment compositions can be provided that meet the aforementioned requirements to a high degree.

[9] The presence of cyclic silicones is not necessary for stability or manageability, nor for improving the care properties of such hair treatment products, because the combination of specific silicones in specific amounts ensures the provision of two-phase systems with continuous oil and continuous water phases, which are storage stable over a wide temperature range (+5°C to 45°C). The two phases can be mixed and unmixed quickly and thoroughly.

[10] In addition, the hair treatment compositions of the invention exhibit a demonstrable conditioning benefit on hair treated therewith. In particular, combability, detangling, shine, smoothness and anti-frizz properties of the hair could be improved by using agents according to the invention.

[11] The present invention and preferred embodiments are characterized by the following

[12] The hair treatment compositions according to the invention comprise two optically separate phases which can be homogenized by shaking, and which separate again at rest into two separate, optically detectable continuous phases with a common horizontal phase boundary.

[13] The emulsion produced by shaking is optimally stable for up to five, preferably up to three, more preferably up to two, and in particular up to one hour before it separates back into the original two phases with a horizontal phase boundary.

[14] For rapid mixing and demixing of the two phases, it can be advantageous if the water phase (I) and the oil phase (II) have lower viscosity values. In the context of the present invention, "lower viscosity values" are preferably understood to mean viscosity values of the water phase (I) and the oil phase (II) of up to a maximum of 1000 mPas each, more preferably 600 mPas and in particular 400 mPas (measured at 20°C with a Brookfield viscometer DV-II, spindle 2 at 20 rpm.

[15] For a better detectability of the mixing and demixing of the two phases, it can be further advantageous if at least one of the phases (I) or (II) is transparent. Under this condition, sufficient mixing of the two phases can preferably be recognized by the fact that only a single phase is still visible, which can be opaque to milky cloudy. In particular, at least one of the two phases (I) and (II) is preferably transparent.

[108] Vitamin H. The compound (3aS,4S,6aR)-2-oxohexahydrothienol[3,4-d]imidazole-4-valeric acid is known as vitamin H, but the trivial name biotin has since become established. Biotin may preferably be present in the hair treatment compositions in amounts of 0.0001 to 1.0% by weight, in particular in amounts of 0.001 to 0.01% by weight.

[109] Particularly preferably, the hair treatment compositions according to the invention may contain vitamins, provitamins and vitamin precursors from groups A, B, E and H. Panthenol, pantolactone, pyridoxine and its derivatives as well as nicotinamide and biotin are particularly preferred and can be added to the hair conditioners according to the invention both individually and in their combination in the amounts mentioned above.

[111] Advantageously, hair treatment compositions according to the invention contain active ingredients for pH regulation in amounts of 0.01 -5 wt.%, preferably 0.01 -3 wt.% and in particular 0.01 to 2 wt.% (based on the total weight of the hair treatment composition).

[112] It has been found that it is advantageous for particularly good stability of the two phases (I) and (II) of the hair treatment composition according to the invention if they contain -if at all -only certain surfactants and/or emulsifiers in specific amounts. In this context, "stability" is understood to mean that the two phases separate again quickly after mixing and form a sharp phase boundary at which optimally no turbidity occurs over a long period of time and with temperature fluctuations.

[113] Surfactants and/or emulsifiers which excessively promote emulsification and/or suspension of the oil phase in the water phase or vice versa are consequently not suitable for use in the compositions according to the invention.

[114] Furthermore, foam formation is undesirable when the hair treatment composition according to the invention is shaken immediately before use, which is why surfactants/emulsifiers that tend to form strong foam are also excluded.

[115] In a preferred embodiment, hair treatment compositions according to the invention -with the exception of those mentioned above -contain a maximum of 1 wt.%, more preferably a maximum of 0.8 wt.%, particularly preferably a maximum of 0.6 wt.% and in particular a maximum of 0.5 wt.% of anionic, amphoteric, zwitterionic and/or non-ionic surfactants or emulsifiers (based on the total weight of the hair treatment composition). Within this embodiment, it is particularly preferred if the hair treatment compositions according to the invention -with the exception of those mentioned so far -do not contain any other anionic, amphoteric, zwitterionic and/or non-ionic surfactants.

[116] Furthermore, it was observed that the presence of various oily and fatty substances can complicate the segregation of the two phases (I) and (II) after their homogenization.

[117] Hair treatment compositions according to the invention which, in addition to the essential and optional ingredients already described, contain in their oil phase (II) a maximum of 0.5% by weight, particularly preferably a maximum of 0.3% by weight and especially a maximum of 0.1% by weight of further oil and/or fatty substances (based on the oil phase (II)) are therefore of particular advantage.

[118] Optimally, the hair treatment compositions according to the invention do not contain any further oil and/or fatty substances, in particular no fatty alcohols, in addition to the components of the oil phase (II) described earlier in this application [119] In another preferred embodiment, hair treatment compositions according to the invention are substantially free of fatty alcohols. By "essentially free" it is understood that the hair treatment compositions according to the invention contain -based on their total weight -a maximum of 0.05% by weight, particularly preferably a maximum of 0.01% by weight and especially 0% by weight of fatty alcohols.

[120] Furthermore, the hair treatment compositions according to the invention may contain further active ingredients, auxiliaries and additives, such as, for example - Structural agents such as maleic acid - Dyes for staining the agent - Anti-dandruff active ingredients such as Piroctone Olamine, Zinc Omadine, Climbazole, Propandiol Caprylate.

- Complexing agents such as EDTA, NTA, p-alaninediacetic acid and phosphonic acids - Pigments - Antioxidants and/or UV filters -Herbal extracts.

[121] In addition to an aesthetic appearance, the two-layer (two-phase) hair treatment compositions according to the invention have the advantage of being easy to handle and simple to manufacture. The special combination of active ingredients in the hair treatment products ensures rapid mixing of the two phases before application and rapid segregation of the two phases after application. The hydrophilic phase is predominantly water-based, which meets consumer needs. Furthermore, the hair treatment compositions according to the invention are particularly suitable for the care of hair. The presence of cyclic silicones is not required for either the stability or the conditioning properties of the hair treatment compositions, because the hair treatment compositions of the invention exhibit good conditioning benefits on hair treated therewith. In particular, the shine, suppleness, detangling, combability and anti-frizz properties of previously stressed and/or damaged hair were significantly improved. The hair treatment compositions according to the invention are sprayable and suitable for application from a pump dispenser. This makes them easy to use and effective in their action, because the fine spray that comes out of the pump dispenser reaches all areas of the hair.

[122] A second object of the invention is a method for conditioning hair in which a hair treatment composition according to the invention is shaken to homogeneity, immediately thereafter applied (preferably sprayed) to wet or dry hair, and left on the hair until the next hair cleaning [123] A third objective of the invention is the use of the hair treatment composition according to the invention for improving hair care, in particular for improving/improving shine, smoothness, detangling, combability, anti-frizz properties.

[124] What has been said about the means according to the invention applies to the method and use according to the invention.
