Problems solved by technology

[0008] However, the choice of ingredients or combination of ingredients is difficult because they must not be detrimental to other cosmetic attributes such as ease and uniformity of application, rheological or viscosity properties and stability of the composition, color deposit and target color form, and / or cause further disadvantages such as increased damage to the hair or a more unhealthy appearance

Embodiment 1

[0279] The amounts of ingredients in the compositions / formulations described below are indicated in Table 1 in % by weight based on the total weight of the cosmetic composition / formulation.

[0280] Table 1:

QS

Diamine*CAS 7300-34-7

[0282] The cosmetic composition described above was prepared by adding (slowly) 4,9-dioxa-1,12-dodecanediamine*, hemeconium chloride and acid to glycerin while mixing the solution. Additional glycerol was added to QS the solution to 100 g. Prepare bleaching powder, 30V oxidizing agent and additives in a mixing ratio of 1:1:0.267 (such as 30g bleaching powder, 30g developer, 8g additive). The composition is applied to the hair.

[0283] Cysteine ​​sulfonic acid is reduced by about 15% compared to a bleach standard with the same boost.

Embodiment 2

[0285] Prepare a mixture comprising bleach powder to 30V oxidizer and additive in a mixing ratio of 1:1:0.267 (eg, 30 g bleach powder, 30 g developer, 8 g additive). The additives include monoethanolamine (MEA) and malonic acid. Apply 10 g of the mixture per 1 g of hair to dry hair and rinse after 45 minutes. Apply conditioner and rinse from hair. Hair is then washed with shampoo and conditioner. Hair is then blow-dried. Cysteine ​​sulfonic acid was reduced by about 16% compared to a bleach standard with the same boost but without additives.

Embodiment 3

[0287] Prepare a mixture comprising bleach powder to 30V oxidizer and additive in a mixing ratio of 1:1:0.267 (eg, 30 g bleach powder, 30 g developer, 8 g additive). The additives include MEA and malonic acid. Apply 10 g of the mixture per 1 g of hair to dry hair and rinse after 55 minutes. Apply conditioner and rinse from hair. Hair is then washed with shampoo and conditioner. Hair is then blow-dried.

[0288] Hair fiber integrity was assessed using the Dia-stron7 Miniature Tensile Tester (MTT). The results are shown in Table 2 below:

[0289] Table 2:

[0290]

[0291]

[0292] As shown in Table 2, the elastic modulus and stress at break were higher for the blends compared to the bleached standard (ie, no additive), indicating that treatment with the blend containing the additive improved the breakage resistance of the hair.

Abstract

The disclosure relates to systems and compositions comprising the systems for use in chemical treatment of keratinous substrates, such as the hair. The systems and compositions comprising the systemscomprise at least one active agent and at least one acid. Methods of treating keratinous substrates with the systems and compositions comprising the systems are also disclosed.

Description

technical field [0001] The present disclosure relates to systems and compositions for chemically treating keratinous substrates such as hair and nails. The systems and compositions comprise at least one active agent and at least one acid. Background technique [0002] It is well known that consumers desire cosmetic and personal care compositions that enhance the appearance of keratinous substrates such as hair, for example by altering the color, style and / or shape of the hair and / or by imparting various properties to the hair such as shine and conditioning. Many known compositions and methods for enhancing the appearance of hair involve chemical treatment of the hair. [0003] Methods of changing hair color, for example, may involve depositing artificial pigments on the hair to give the hair a different shade or color, and / or to enhance the color of the hair, such as lightening dark hair color to a brighter color. Methods of enhancing hair color (also known as lightening) ...
