Description

[Technical Field]

[0001] The present invention relates to a granulated hair dye composition, a method for preparing the same, and a method for using the same. The granulated hair dye composition comprises a natural hair dye, a natural thickener, and optionally a direct dye, wherein the natural dye is coated with the natural thickener to form granules. The present invention provides a dust-free composition that contains fewer materials than conventional non-oxidizing hair dye compositions, is mostly of natural origin, is easily mixed with water, can be applied to the hair as a poultice with minimal or no dripping, provides an improved user dyeing experience and uniform hair dyeing, and also provides excellent shine and a greatly improved hair feel. [Background technology]

[0002] Hair is generally dyed using either oxidative or non-oxidative hair dyeing methods.

[0003] Oxidative hair dyeing is achieved by using an oxidative hair dyeing composition that includes at least an oxidative dye (including primary intermediates and couplers), an oxidizing agent, and an alkalizing agent. Oxidative hair dyeing methods provide long-lasting (permanent) hair color, good washability, and a wide variety of shades. However, the above methods are cumbersome, can damage hair, and may cause allergic reactions or skin hypersensitivity.

[0004] Non-oxidative hair dyeing is achieved by using non-oxidative hair dyeing compositions that contain natural dyes and / or direct dyes, but typically do not contain any oxidizing agents and / or alkalizing agents. Non-oxidative hair dyeing methods provide only semi-permanent hair dyeing, while minimizing or completely avoiding damage, and minimizing or completely avoiding allergic reactions or skin hypersensitivity.

[0005] In recent years, users, consumers, and barbers have shown great interest in using non-oxidative hair dyeing methods as an alternative to oxidative hair dyeing methods. In particular, users have shown unprecedented interest in “natural and safe” products—that is, products containing naturally derived compounds, especially those derived from plants, and containing as few synthetic chemical compounds, especially those derived from crude oil, as possible. There is also unprecedented interest in “simple and effective” products—that is, products with low levels of compounds without sacrificing effectiveness.

[0006] Natural dyes such as henna powder (Lawsonia inermis leaf powder) and powders from indigo-producing plants (e.g., Indigofera tinctoria leaf powder) have been used for centuries to dye keratin fibers, especially hair. Other natural dye powders are also obtained from, for example, chamomile flowers, curcuma root, rhubarb, buckthorn bark, olive tree leaves, Canadian bloodroot, turmeric, yellowwood, redwood, logwood, madder root, black elderberry, and black chokeberry.

[0007] Coarse raw material powders are traditionally mixed with water, especially warm water, before being applied to hair as a coating agent. However, such coarse raw material powders usually contain granules of various sizes, making the mixing process with water to obtain a coating agent difficult and resulting in an uneven mixture. Fine powders have also been used. However, despite potentially being easier to mix with water, such fine powders generate a lot of dust. In addition, the resulting mixture can be difficult to wash off after application to the hair, potentially leading to uneven dyeing of keratin fibers. Furthermore, these coarse raw material powders may undergo separation of components with different densities during transport and storage. Therefore, heavier components tend to accumulate at the bottom of the container, while lighter components tend to accumulate at the top. Thus, the same amount of powder mixture may yield different compositions and consequently different dyeing results, which is undesirable to users.

[0008] Various formulations have been developed with the aim of providing dust-free hair dyeing compositions with satisfactory dyeing performance. For example, U.S. Patent No. 6,302,920 B1 specifically discloses a fluid, powdery decolorizing or dyeing composition coated or agglomerated by spraying a molten wax compound having a flow point between approximately 40°C and approximately 130°C. European Patent Applications EP 0806199 A1 and EP 0806200 A2 specifically disclose hair dyeing compositions in the form of suspensions, comprising powdered natural dyes and oils. International Applications WO 2013 / 083701 A1 and WO 2013 / 083702 A1 disclose hair dyeing compositions comprising natural dyes and oils and / or butters. International Application WO 2014 / 174113 A2 specifically discloses hair dyeing compositions comprising natural dyes, oils and sugars. These compositions may exhibit reduced dustiness and may provide satisfactory dyeing results. However, the presence of oil can negatively affect the miscibility of the hair dye composition with water, and even with hot water, potentially complicating the mixing and application processes to the hair. In addition, the presence of oil can leave residue on the hair, leaving it greasy even after the application agent has been washed off, potentially requiring excessive shampooing, which could worsen the hair's texture and weaken the color result.

[0009] Therefore, there remains a need for dust-free, non-oxidizing hair dye compositions that can be easily mixed with water before application to the hair. There is also a need for non-oxidizing hair dye compositions that consist mostly of natural compounds, especially plant-derived compounds, without sacrificing dyeing performance. There is also a need for simple non-oxidizing hair dye compositions, i.e., compositions that, as usual, contain small amounts of compounds but do not sacrifice dyeing performance. There is a need for fluid non-oxidizing hair dye compositions that, after mixing with water, can be applied to the hair as a coating agent with minimal or no dripping. There is also a need for hair dye compositions that provide an improved user dyeing experience and uniform hair dyeing, but without gloss and hair texture. There is also a need for hair dye compositions that provide improved gloss and hair texture. [Overview of the Initiative]
