Description

[Technical field]

[0001] The present invention relates to hair treatment compositions, in particular anti-dandruff shampoo compositions. [Background technology]

[0002] Dandruff is a problem that affects many people worldwide. The condition is caused by dead hair growing from the scalp. It appears as a white, cosmetically unpleasing mass of skin cells that have become shed. Dandruff is caused by certain members of the yeast genus Malassezia. To combat these, hair treatment compositions containing a variety of anti-dandruff actives are available. Piroctone compounds such as piroctone olamine have been developed to have such activity. It is one of the sexual agents.

[0003] A common problem with piroctone compounds is their deposition on the hair or scalp during the washing process. This is difficult to achieve with effective anionic chlorine ions such as sodium laureth sulfate. This is especially true when cleansing surfactants are present in the composition. When washing is performed, most of the piroctone is likely to be washed away along with the surfactant. Insufficient deposition correlates with low antidandruff activity, so the dandruff problem is hardly alleviated. To date, there have been no studies to increase the level of piroctone olamine in hair treatment compositions. Attempts have been made to offset this shortcoming by These include increased cost, potential instability of the formulation, and potential adverse effects on the sensory properties of the hair. This causes a variety of problems, and is therefore not an approach favored by the industry.

[0004] DE102012203240A1 contains anti-dandruff agents, which improve combability, shine and elasticity of hair. A hair treatment composition having improved strength is described. The composition contains zinc pyridinium. Thione, climbazole, octopirox, ketoconazole, selenium disulfide, selenium-containing an anti-fungal agent selected from the group consisting of plant oils, selenium-containing plant extracts, and cationic amino silicones; Examples include Octopirox (piroctone olamine). Shampoos and conditioners containing amino silicones and surfactants are also available. do.

These preparations exhibit improved sensory properties and sufficient microbiological stability.

[0006] EP0941061 discloses a surfactant, a polyethyleneimine, and a piroctone olamine. The presence of polyethyleneimine in the composition is believed to improve hair and It is said to enhance the deposition of active piroctone olamine into the skin.

[0007] From 2016 to 2019, "Ultra Doux" and "Nak" were sold in China. Various commercial products allegedly sold under the trade names, among others, lauryl ether sulfate surfactants, Betaine surfactant, piroctone olamine, polyquaternium-6 and amodimethicone However, particularly in the case of Nak products, the product is commercially available It is not clear whether this occurred before the priority date of this patent application.

The optional ingredients may be used in the composition, provided that they are physically and chemically compatible with the essential ingredients previously described herein. or otherwise unduly impair sensory, formulation rheology, and conditioning performance. The individual concentrations of such optional ingredients may range from 0.001% to 10% by weight of the total composition. Such components may be present in an amount of from 0.01% to 5% by weight. For example, fragrances, dyes and pigments, pH regulators, pearlescent agents or milk Whitening agents, viscosity regulators, preservatives, as well as botanical ingredients, fruit extracts, sugar derivatives and amino acids The composition may contain additional silicones not included in the oil-in-water emulsion phase. The additional silicone may be mixed with the silicone in the emulsion phase. They may be the same or different.

[0084] The composition includes pyridinethione salts, pine root tar, sulfur, salicylic acid, azoles, selenium sulfide, The composition may also contain additional anti-dandruff and / or antimicrobial agents, such as dandruff, ketones, glycerol ... stomach.

[0085] How to use The composition is used in a surface treatment method. An effective amount of the composition is applied to a surface, preferably moistened with water. The composition is applied to the desired surface selected from the hair and / or scalp. To achieve this, the agent is allowed to remain on the surface for a period of time, preferably in combination with massage, and then The predetermined time is preferably 20 seconds to 2 minutes, more preferably 30 The effective amount is typically in the range of 1 g to 20 g, preferably 2.5 g to 10 g. It is surrounded by.

[0086] The invention can be illustrated by the following non-limiting examples. EXAMPLES

[0087] The following examples were prepared:

[0088] Table 1 [Table 1]

[0089] 0.1 g / g of the composition of the embodiment was evenly applied onto the hair switch. After cleaning, the switches were placed in a drying cabinet (50°C) until dry. After drying, the switch was transferred to a jar containing 10 mL of ethanol. The jar was sealed and the bottle was Using a syringe, a sample of a suitable size for analysis was The solution was then removed from the flask, filtered through a syringe filter, and placed in a vial for analysis using HPLC-UV. Using the method, a series of standards containing known amounts of octopirox (μg / mL) in ethanol were The material was analyzed.

[0090] Table 2 - Octopirox Deposition [Table 2]

[0091] The examples of the present invention deposit octopirox more effectively into hair than the comparative examples. .

[0092] Example 2 As specified (by weight of composition): Sodium Laureth Sulfate 13.0%, Cocamide Propylene Glycol 1.0%, Pyrbetaine 1.5%, DC1788 Silicone Emulsion 2.0%, Carbopol 9 80 0.4%, Fragrance 0.75%, Piroctone Olamine 0.5%, Water up to 100%, Storage A shampoo composition containing a surfactant, citric acid, and sodium hydroxide was widely used at the following levels: Piroctone olamine deposition was investigated using a range of deposition polymers. The amounts listed were Deposition amounts are in ppm with standard deviations given in parentheses. [Table 3]

[0093] The deposition of piroctone olamine with polyquaternium-6 as a deposition polymer was similar to that of other Although relatively high compared to the polymers, beneficially, it also shows a dose response.
