Description

[Technical Field]

[0001] This invention relates to cosmetic products for dyeing and / or decolorizing keratin fibers. Furthermore, it discloses methods for decolorizing and / or dyeing. [Background technology]

[0002] Bleaching and dyeing processes have been a focus of interest for the past several decades, particularly in the cosmetics industry. The challenges associated with these processes, which still exist today, relate to damage, strength, and durability.

[0003] In particular, if keratin fibers have been previously damaged by chemical services such as perms or bleaching, direct dyes will have lower durability on keratin fibers. Chemical services can alter the internal structure of the hair, improving dye absorption compared to virgin hair, but at the same time, they can also cause direct dyes to wash out more easily. Therefore, consumers who have previously chemically treated their hair may experience a decrease in the durability of direct dyes, especially after several washes. Furthermore, while the color intensity weakens over several washes, the hair may also undergo undesirable color transfer depending on the different leaching rates of individual direct dyes.

[0004] In the daily operations of a hair salon, analyzing the pre-treatment damage to a client's hair is not always easy, even for professionals. Some pre-applied treatments may have already been washed away, and their effects are no longer visible. Assuming healthy hair is the basis for direct dyeing, the exceptionally low durability of the dye treatment can be a surprise to both the hairdresser and the client. Such an experience is disappointing for everyone involved.

[0005] In short, prior art has not adequately solved the above problems, and therefore there is a real need to develop a direct dyeing composition for keratin fibers that exhibits high dyeing strength and good durability regardless of the chemical treatment history.

[0006] The prior art does not fully solve this problem.

[0007] For example, Patent Document 1 focuses on the stability of the formulation, but does not focus on the chemical stability of the aqueous oxidation composition.

[0008] Xanthine and its derivatives are well-known components in dermatology and the food industry. Furthermore, caffeine-containing cleaning compositions are well-known (e.g., Mintel #6713099).

[0009] Patent Document 2 describes an aqueous oxidation composition containing 5% by weight or less of hydrogen peroxide and a purine derivative, particularly caffeine. It has been found that the purine derivative reduces damage to keratin fibers.

[0218] The following examples illustrate the invention and are not intended to limit it. Example 1

[0219] Composition A wt% Hydroxyethyl cellulose 3 EDTA tetrasodium 2 Sodium carbonate 1 Ammonium persulfate 11 Potassium persulfate 36 Sodium metasilicate 10 Mineral oil 8 Up to 100 of diatomaceous earth

[0220] Composition B Weight % Cetearyl alcohol 4.0 Sodium lauryl sulfate 0.8 Appropriate amount of phosphoric acid until pH 1.5 EDTA tetrasodium 0.05 Hydrogen peroxide 6.0 Up to 100.0 of water

[0221] Composition C Weight % Caffeine 100

[0222] Composition A and B were mixed at a weight ratio of 1:1.4, and Composition C was added (to obtain 0.004 wt% - 0.4 wt% of caffeine in the mixture prepared at the time of use).

[0223] It was found that it had the following damage reduction value while maintaining the same degree of lightening.

[0224]

Table 1

[0225] The following Composition C was prepared.

[0226]

Table 2

[0227] Composition A and B were mixed at a weight ratio of 1:1.4, and Composition C was added (to obtain 0.08 wt% - 0.404 wt% of caffeine in the mixture prepared at the time of use).

[0228] method Hair bleaching Human hair strands (21 cm, 2 g per strand) were coated with 12.1 g of the ready-to-use composition, mixed as described above, and left to stand at 40°C for 30 minutes. The hair strands were then rinsed with lukewarm water, shampooed with Goldwell Deep Cleansing Shampoo (a commercially available shampoo), and blow-dried. The color was measured as outlined below.

[0229] Assessment of hair damage To assess damage, each of the 25 hair samples was measured under wet conditions using a Diastron tensile testing machine, and stress-strain curves were obtained. The post-yield region, which may be due to the effects of sulfur bonds, was weakened due to oxidation during the decolorization process and was therefore considered an indicator of oxidative damage. The post-yield gradient was calculated and compared to the post-yield gradient obtained using the same decolorization mixture but without the activator from composition C.
