Patent Application
20200323757
The present disclosure concerns a kit for preparing a body treatment agent, in particular a hair treatment agent, and a mixing device for producing a liquid mixture, comprising such a kit.
In many areas of daily life there is a continuing trend towards personalized programs that respond to the individual requirements and needs of a customer or user. This is the case, for example, in the areas of nutrition or health care and also in the field of personalized cosmetics. This enables the consumer or user of cosmetic treatment products to receive individual treatment instructions and cosmetic treatment products that are specifically tailored to the individual needs of, for example, his hair or skin and thus enables a particularly high degree of effectiveness.
A hairdresser may determine the current hair condition (damaged, dull, brittle, etc.) of a customer with the help of his experience and/or with suitable analysis equipment. Usually, he then resorts to products available in the hairdressing salon when choosing the appropriate hair treatment product.
Conventional, commercially available hair treatment products are available as a limited product range for a given application. For example, each manufacturer of shampoos, deep conditioners or hair colors provides a limited range of products. Even though a user's hair condition may be known, it may be impossible to achieve an optimal treatment result, but usually only a result close to the desired result can be achieved.
It is therefore desirable to produce a cosmetic hair treatment product for the user on site, for example in a hairdressing salon or at a point of sale, on the basis of the determined hair condition and individually tailored to the hair condition.
However, manually mixing different hair treatment products, for example, components for a shampoo, conditioner, deep conditioner or hair dye, is a challenge for the hairdresser or the user himself. An optimal mixing result may only be achieved if the individual components are mixed exactly in their predefined proportions. For example, when manually mixing several components from bottles, a portion of one component may remain in the bottle excessively, so that the mixture may lack a portion of one component.
By employing a mixing device comprising a plurality of viscous liquid reservoirs containing body treatment product ingredients, a plurality of pumps for conveying the viscous liquids and a static mixer, it is possible to produce a desired body treatment product accurately and easily by mixing at least two liquids.
There are numerous requirements to be met by the liquids in the storage tanks: for example, they must be easy to mix, pump well and precisely and he stable in storage. In addition, they should be able to contain high concentrations of active ingredients and/or additives, such as oils, perfumes, so that even small quantities of the desired hair treatment product may be prepared, for example, for a single application.
Consequently, there is a demand for a kit comprising a plurality of liquids containing ingredients of body treatment products which, when used in a mixing device, enables an individual body treatment product, in particular a hair treatment product, to be prepared for a user in a standardized and objective manner.
This task is solved by a kit comprising at least two base liquids for the preparation of a body treatment product, each base liquid containing at least about 10% by weight of a surfactant mixture comprising or consisting of anionic surfactants, amphoteric surfactants and non-ionic surfactants.
It is particularly preferred that each base liquid contains at least about 10% by weight of a surfactant mixture comprising or consisting of alkyl ether sulfates, alkyl amido alkyl betaines and alkamide monoethanolamines.
In certain embodiments, a kit comprising at least two base liquids for the preparation of a body treatment composition is provided. In an exemplary kit, each base liquid contains at least about 10% by weight of a surfactant mixture comprising anionic surfactants, amphoteric surfactants and nonionic surfactants. In exemplary embodiments, the surfactant mixture comprises alkyl ether sulfates, alkyl amidoalkyl betaines and alkamide monoethanolamines.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
The following detailed description is merely exemplary in nature and is not intended to limit the disclosure or the application and uses of the subject matter as described herein. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.
Surprisingly, it has been discovered that base liquids with this surfactant mixture are very readily miscible with one another. In addition, various ingredients of body treatment products are compatible with these surfactants and may be introduced stably into the base liquids.
Preferred alkyl ether sulfates are selected from the group consisting of C4 to C24, preferably C6 to C18, particularly preferably C8 to C14 alkyl ether sulfates. The alkyl radicals may be linear or branched, linear alkyl ether sulfates being preferred.
The addition of an alkyl or alkenyl group with the suffix “eth” generally describes the addition of one or more ethylene oxide units. The number of ethylene oxide units is characterized by the addition of an integer.
Particularly preferred alkyl ether sulfates have a C12 alkyl group (lauryl group) and include ammonium laureth sulfates, ammonium laureth-5 sulfates, ammonium laureth-7 sulfates, ammonium laureth-9 sulfates, ammonium laureth-12 sulfates, DEA-laureth sulfates, magnesium laureth sulfates, magnesium laureth-5 sulfates, magnesium laureth-8 sulfates, magnesium laureth-16 sulfates, MEA laureth sulfates, MIPA laureth sulfates, potassium laureth sulfates, sodium laureth sulfates, sodium laureth-5 sulfates, sodium laureth-7 sulfates, sodium laureth-8 sulfates, sodium laureth-12 sulfates, sodium laureth-40 sulfates, TEA laureth sulfates and mixtures thereof. A particularly preferred alkyl ether sulfate is sodium laureth sulfate (sodium lauryl ether sulfate).
Preferred alkyl amido alkyl betaines comprise in particular C4 to C24, preferably C6 to C18, particularly preferably C8 to C14 alkyl amido propyl betaines. The alkyl radicals may be linear or branched, linear alkyl amido propyl betaines being preferred.

It is preferred that the amount of alkyl ether sulfates is from about 7 to about 15% by weight, the amount of alkyl amidoalkyl betaines is from about 1.5 to about 4% by weight and the amount of alkamide monoethanolamines is from about 1 to about 2% by weight, in each case based on the total amount of base liquid.
It is also preferred that the surfactant mixture contains sodium lauryl ether sulfate (INCI: Sodium Laureth Sulfate), cocamidopropyl betaine (INCI: Cocamidopropyl Betaine) and N-(hydroxyethyl) coconut fatty acid amide (INCI: Cocamide Monoethanolamine).
Accordingly, it is particularly preferred that the surfactant mixture contains from about 7 to about 15% by weight of sodium lauryl ether sulfate, from about 1.5 to about 4% by weight of cocamidopropyl betaine and from about 1 to about 2% by weight of N-(hydroxyethyl)coconut fatty acid amide, in each case based on the total amount of base liquid.
Base liquids containing the triple combination of selected surfactants are structurally viscous and thus very easy to pump. The base liquids may also be dosed well and precisely. This makes it possible to prepare individual body treatment products in commercially available quantities ranging from a few ml for single use to several hundred ml, especially about 250 ml or about 400 ml.
In various forms, at least one base liquid also contains a substance selected from dialkyl sulfosuccinates and dialkyl methyl sulfosuccinates.
Preferably dialkyl sulfosuccinates and/or dialkyl methyl sulfosuccinates contained in the at least one base liquid are selected from the group consisting of dialkyl sulfosuccinates and/or dialkyl methyl sulfosuccinates in which the alkyl radicals each have 4 to 24, preferably 6 to 18, particularly preferably 6 to 14 carbon atoms. The alkyl radicals may be linear or branched, branched ones being preferred. Different or identical alkyl radicals in a molecule may be dialkyl sulfosuccinate and/or dialkyl methyl sulfosuccinate where identical ones are preferred.
Alkali metal cations, alkaline earth cations or ammonium ions, especially sodium, may preferably be used as counter ions to the sulfonic acid group. In particular, dialkyl sulfosuccinates are contained in the base liquids. The preferred dialkyl sulfosuccinates are selected from the group consisting of diethylhexyl sodium sulfosuccinates, dinonyl sodium sulfosuccinates and di-isononyl sodium sulfosuccinates, dioctyl sodium sulfosuccinates, diheptyl sodium sulfosuccinates, dihexyl sodium sulfosuccinates, dineopentyl sodium sulfosuccinates, diisoamyl sodium sulfosuccinates, dipentyl sodium sulfosuccinates, diamyl sodium sulfosuccinates, dibutyl sodium sulfosuccinates, diisobutyl sodium sulfosuccinates, dicapryl sodium sulfosuccinates, didecyl sodium sulfosuccinates, diundecyl sodium sulfosuccinates, dilauryl sodium sulfosuccinates, dicocoyl sodium sulfosuccinates, ditridecyl sodium sulfosuccinates, dipropylheptyl sodium sulfosuccinates, dicyclohexyl sodium sulfosuccinates, ammonium diethylhexyl sulfosuccinates, ammonium dinonyl sulfosuccinates, ammonium disononyl sulfosuccinates, ammonium dioctyl sodium sulfosuccinates, ammonium diheptyl sulfosuccinates, ammonium dihexyl sulfosuccinates, ammonium dineopentyl sulfosuccinates, ammonium diisoamyl sulfosuccinates, ammonium dipentyl sulfosuccinates, ammonium diamyl sulfosuccinates, ammonium dibutyl sulfosuccinates, ammonium diisobutyl sulfosuccinates, ammonium dicapryl sulfosuccinates, ammonium didecyl sulfosuccinates, ammonium diundecyl sulfosuccinates, ammonium dilauryl sulfosuccinates, ammonium dicocoyl sulfosuccinates ammonium ditridecyl sulfosuccinates, ammonium dipropylheptyl sulfosuccinates, ammonium dicyclohexyl sulfosuccinates, diethylhexyl potassium sulfosuccinates, dinonyl potassium sulfosuccinates, diisononyl potassium sulfosuccinates, dioctyl potassium sulfosuccinates, diheptyl potassium sulfosuccinates, dihexyl potassium sulfosuccinates, dineopentyl potassium sulfosuccinates, diisoamyl potassium sulfosuccinates, dipentyl potassium sulfosuccinates, diamyl potassium sulfosuccinate, dibutyl potassium sulfosuccinate, diisobutyl potassium sulfosuccinate, dicapryl potassium sulfosuccinate, didecyl potassium sulfosuccinate, diundecyl potassium sulfosuccinate, dilauryl potassium sulfosuccinate, dicocoyl potassium sulfosuccinates, ditridecyl potassium sulfosuccinates, dipropylheptyl potassium sulfosuccinates, dicyclohexyl potassium sulfosuccinates, with diethylhexyl sodium sulfosuccinates being particularly preferred.
It is preferred that the at least one base liquid also contains diethylhexyl sodium sulfosuccinate (sodium dioctyl sulfosuccinate), which is available from Evonik under the name Tego® Sulfosuccinate DO 75.
The amount of dialkyl sulfosuccinate, in particular of diethylhexyl sodium sulfosuccinate, is preferably from about 2 to about 20% by weight, more preferably from about 7 to about 15% by weight, each based on the total amount of base liquid.
In various forms, at least one base liquid may further comprise a substance with the INCI designation “Guar Hydroxypropyltrimonium Chloride”, which has a nitrogen content of from about 1.9 to about 2.4% and/or a molar mass average value in the range from about 15,000 to about 25,000 daltons.
Guar Hydroxypropyltrimonium Chloride is a quaternary trimethyl hydroxy propyl ammonium salt based on guar gum and is added to body treatment products, especially hair treatment products, as a care substance. Due to its cationic charge Guar Hydroxypropyltrimonium Chloride absorbs on hair or skin surfaces or flocculates together with present anionic surfactants on hair or skin surfaces. In both cases this leads to a smoothing of the surface and produces an increase in gloss, easier combing, an antistatic effect and an improved skin feel.
Conventional Guar Hydroxypropyltrimonium Chloride can only be incorporated in surfactant-containing compositions in small amounts (up to about 1% by weight). At higher amounts the resulting compositions show too high viscosities and are no longer pumpable or otherwise processible.
Surprisingly, it has been discovered that Guar Hydroxypropyltrimonium Chloride, which has a nitrogen content of from about 1.9 to about 2.4% and/or a molar mass average value in the range of from about 15,000 to about 25,000 daltons, may be incorporated into a surfactant-containing base liquid even in quantities of >1% by weight without having any adverse effects on the viscosity and thus on the further processability of surfactant-containing base liquid. Guar Hydroxypropyltrimonium Chloride with a nitrogen content of from about 1.9 to about 2.4% and a molar mass average value in the range of from about 15,000 to about 25,000 daltons is available from Solvay, for example, under the name Jaguar® Optima.
The amount of Guar Hydroxypropyltrimonium Chloride, which has a nitrogen content of from about 1.9 to about 2.4% and/or a molar mass average value in the range of from about 15,000 to about 25,000 daltons, amounts preferably to between about 0.02 and about 2% by weight and more preferably to between about 0.05 and about 1.1% by weight, in each case based on the total weight of the base liquid.
In various embodiments, at least one base liquid also contains at least about 1% by weight, based on the total weight of the base liquid, of a substance with the INCI designation “Guar Hydroxypropyltrimonium Chloride”, which has a nitrogen content of from about 1.9 to about 2.4% and/or a molar mass average value in the range from about 15,000 to about 25,000 daltons.
In various embodiments, the base liquids have a viscosity of >5000 mPas (Brookfield DV 2+, spindle 5, 20 rpm, 20° C. and 60 seconds). It is preferred that the base liquids each have a viscosity in a range of from about 5,000 to about 20,000 MPas.
It is particularly preferred that the base liquids have a pseudoplastic viscosity. Structurally viscous liquids are non-Newtonian liquids whose deformation behavior can no longer be described using Newton's law. The viscosity of non-Newtonian liquids changes in particular with shear rate and/or load duration.
In various embodiments, the kit contains at least about 4, more preferably at least about 8 and most preferably at least about 10 base liquids.
The more base liquids the kit comprises, the greater the variance in the body surface treatment agents that may be prepared with them. Accordingly, individual body treatment products may be prepared that are optimally adapted to the user's needs.
In various embodiments, the base liquids each contain at least one ingredient selected from the group consisting of oils, perfumes, inorganic salts, organic acids, anti-dandruff agents, care substances, preservatives and colorants.
Surprisingly, it has been discovered that in particular high concentrations of oil, perfume and/or skin care products may be stably incorporated into a base liquid without any adverse effects, such as greatly reduced viscosity, phase separation, or the like, preventing or greatly complicating further processing, for example mixing in a mixing device.
