Hair dye in the form of a creamy permanent foam or a stably foamed dye cream

The invention relates to a hair dye in the form of a creamy permanent foam or in the form of a stably foamed dye cream.

In addition to the product services they primarily expect, cosmetic products are subject to special requirements with regard to the sensory properties transmitted to the user. Hair colorants are often in the form of creamy emulsions or dispersions and consist of an aqueous, hydrophilic phase and a hydrophobic phase containing oil or wax substances. A disadvantage of these conventional emulsion or dispersion-shaped hair coloring products is their sensors, in particular their haptics. The products often feel too heavy, greasy and greasy. In addition, relatively high amounts of dyes or dye precursors are required to achieve a sufficient dyeing result. In addition, an improved spreadability on the hair is desirable.

Hair colorants in the form of temporary, unstable foams foamed immediately before use are known. These are aerosol products which are foamed to form an unstable foam when they are removed from a pressure container using a propellant gas (foam tints). Such temporary foam-forming products have the disadvantage that the foam 4-1

and after storage for at least one week at room temperature (20 ° C), the density is still less than or equal to 0.95 g / ml.

In the agents according to the invention, the masses are stably foamed with air or an inert gas up to a degree of foaming of typically at least 5% and up to 500%, preferably between 10 and 200%, particularly preferably between 10 and 50%. The degree of foaming in the sense of the present invention represents the volume ratio and is calculated from the densities of the composition before and after foaming as follows:

[(D ₀ / D) -1] * 100% where D ₀ denotes the density before foaming and D the density after foaming. In addition to air, gases which are particularly suitable for foaming are inert gases, for example nitrogen, carbon dioxide, nitrogen oxides, noble gases or mixtures of the gases mentioned. The use of inert, oxygen-free gases such as nitrogen or carbon dioxide for the production of foamed products containing oxidation-sensitive substances, for example oxidation-sensitive dye precursors, is particularly advantageous.

The terms 'stable foamed' or 'permanent foam' refer to product masses which are characterized in that a gaseous substance in the form of gas bubbles is homogeneously distributed in them and in this homogeneous distribution over a period of at least one week, preferably at least 1 Month, particularly preferably at least 6 months when stored at room temperature (20 ° C.), ie the density is still less than or equal to 0.95 g / ml, preferably is still less than or equal to 0.90 g / ml. Gas bubbles with a size of preferably between 0.0001 and 10 mm, particularly preferably between 0.01 and 1 mm, are contained in the foamed product masses. The average diameter of the gas bubbles is preferably from 0.1 to 0.8 mm, particularly preferably from 0.2 to 0.4 mm.

To produce the agents according to the invention, liquid, viscous, foam-forming and at least at room temperature (20 ° C.) have a yield point

Suitable compositions. These can be dispersions consisting of a hydrophilic and a hydrophobic phase or of single-phase compositions containing a thickener or a hydrocolloid.

The agent according to the invention can be prepared by (A) introducing a liquid, foamable composition which has a flow limit at room temperature (20 ° C.) and contains at least one direct hair dye or at least one oxidation dye precursor and (B) subsequently or simultaneously Whipping or foaming the composition with air and / or an inert gas to a density of less than or equal to 0.95 g / ml.

Agents according to the invention can in particular be produced by (A) either presenting a liquid, foamable

Composition containing a hydrophilic phase, a hydrophobic phase, at least one surfactant and at least one substantive hair dye or at least one oxidation dye precursor, the hydrophobic phase containing at least one substance which is solid at room temperature (20 ° C.) or by presenting a liquid, foam-forming aqueous composition containing a combination of at least one thickener and at least one surfactant and subsequently or simultaneously

(B) Whipping or foaming the composition with air and / or an inert gas, the introduced air and / or the introduced inert gas or the bubble structure produced even when stored for at least one month at room temperature

(20 ° C) remains stable in the mass.

The invention also relates to a correspondingly manufactured product, i.e. a hair dye in the form of a creamy permanent foam or in the form of a stably foamed cream, which has a hydrophilic phase, a hydrophobic phase, at least one surfactant, at least one direct hair dye or at least one oxidation dye precursor and at least one gas stably introduced into the composition or at least contains a thickener, at least one surfactant, at least one substantive hair dye or at least one oxidation dye precursor and at least one gas stably introduced into the composition.

Preferred agents have a content

(a) water,

(b) at least one wax or fat-like substance that is solid at room temperature (20 ° C.), (c) at least one surfactant,

(d) at least one foam stabilizer and

(e) at least one substantive hair dye or at least one oxidation dye precursor. Hydroph le phase

The term 'aqueous phase' or 'hydrophilic phase' encompasses water and mixtures of water with water-soluble, cosmetically compatible, organic solvents such as e.g. lower mono- or polyhydric alcohols, especially polyhydric C2 to C alcohols such as Ethylene glycol, diethylene glycol, butylene glycol or glycerin. Because of their foam-inhibiting effect, lower monohydric alcohols such as ethanol or isopropanol should either not be present or should only be present in very small amounts which do not interfere with foam formation.

Hydrophobic phase The term 'hydrophobic phase ¹ comprises a phase with a content of hydrophobic, water-insoluble wax, fat or oil substances. These can be liquid or solid at room temperature, preferably containing at least one hydrophobic substance which is in solid form at room temperature (20 ° C.), since this increases the stability of the foamed product.

The hydrophobic substances, which are in solid form at room temperature (20 ° C.), are either added in the molten state or they are added in the solid state to the hydrophilic phase which has been heated to above the melting point. These can be waxes or wax-like substances, e.g. natural, renewable waxes (insect, animal and plant waxes), fossil waxes (petroleum, brown coal, peat waxes or ozokerites), synthetic waxes (Fischer-Tropsch -, polyethylene or amide waxes), higher-melting paraffins, esters, fats, long-chain carboxylic acids or long-chain (CIO to C22) alcohols, each with melting or solidification points above room temperature (20 ° C).

In addition to the hydrophobic solid, the hydrophobic phase can also contain hydrophobic substances present in liquid form at room temperature. These can be oils or oily substances, e.g. around naturally occurring, renewable oils (vegetable and animal fatty oils), synthetic oils, silicone oils, mineral oils, essential oils, water-insoluble, branched or linear aliphatic hydrocarbons, linear or branched alcohols, in particular liquid fatty alcohols and long-chain ethers or esters, the substances mentioned preferably have at least 8 carbon atoms. Suitable hydrocarbons are e.g. liquid paraffins, squalane or squalene. Also suitable are esters of trihydric and polyhydric alcohols, especially vegetable triglycerides such as e.g. Olive oil, almond oil, peanut oil, sunflower oil and synthetic triglycerides such as C8-C10-trifatty acid glycerol ester or jojoba oil.

Also suitable as a hydrophobic substance are mono- or diesters of the formulas R ¹ - (C = 0) OR ² , R ¹ - (C = 0) OR ³ - 0 (C = 0) R ¹ and R0 (C = 0) - R ³ - (C = 0) OR ² , where R ^{1 is} a C8 to C22 alkyl group, R ^{2 is} a C3 to C22 alkyl group and R ^{3 is} a C2 to C16 alkylene group.

Naturally occurring monoester or

Wax ester mixtures, e.g. present in jojoba oil or sperm oil and branched primary alcohols, as they are known under the name Guerbet alcohols.

Also suitable as hydrophobic substances are substances which are usually used as opacifiers in cosmetic agents are used, in particular those of the formula R ^x -COO- (CHR ⁴ CHR ⁵ 0) _n -COR ^6, wherein R ¹ represents a C8 to C22 alkyl group, R ⁴ and R ⁵ - ^ RUER hydrogen or methyl and R ^{6 represents} hydrogen or R ¹ and n represents a number between 1 and 12, preferably 1, 2, 3 or 4. Preferred are glycol difatty acid esters and polyethylene glycol difatty acid esters, which are in solid form at room temperature.

The proportion of the hydrophobic phase in the unfoamed dispersion depends on the requirements of the end product to be produced. It can be from 5 to about 50% by weight. The hydrophilic phase then makes up from 50 to 95% by weight. However, it is advisable to choose the type and amount of the dispersed substances so that, as described in more detail below, there is a sufficiently high viscosity and a yield point for both the non-foamed and the foamed compositions.

Ten ide

The hydrophilic and hydrophobic phases can be homogenized without an emulsifier. However, at least one surfactant is preferably used as a dispersing aid. This then results in a fine-pored foam when foaming. The surfactant can be present in amounts of 0.1 to 30% by weight, preferably 0.2 to 5% by weight, based on the unfoamed composition. Non-ionic, anionic, cationic, amphoteric or zwitterionic surfactants are suitable as surfactants. Suitable surfactants are, for example, those in the 'International Cosmetic Ingredient Dictionary and Handbook', 7th edition, volume 2 in the section 'Surfactants', especially in the Subsection 'Surfactants - Emulsifying Agents' listed surfactants.

Nonionic surfactants are, for example, ethoxylated fatty alcohols, ethoxylated nonylphenols, alkyl polyglycosides, fatty acid mono- and diglycerides, ethoxylated and hydrogenated or non-hydrogenated castor oil, fatty acid alkanolamides, and ethoxylated fatty acid esters. Cationic surfactants are, for example, long-chain quaternary ammonium compounds such as are known under the CTFA designations "Quaterium", such as alkyltrimethylammonium salts or dialkyldimethylammonium salts with C8 to C22 alkyl groups. Suitable cationic surfactants can be represented by the general formula (I), N '^ R'R'R'R ⁴ X (I) where Rl to R4 independently of one another are aliphatic groups, aromatic groups, alkoxy groups, polyoxyalkylene groups, alkylamido groups, hydroxyalkyl groups , Aryl groups or alkaryl groups each having 1 to 22 carbon atoms, at least one of the radicals R 1 to R 4 having at least 8 carbon atoms and X ^{(_) being} a cosmetically acceptable anion, for example a halogen, acetate, phosphate, nitrate or alkyl sulfate , preferably a chloride. In addition to the carbon atoms and the hydrogen atoms, the aliphatic groups can also contain cross-links or other groups such as further amino groups. Examples of suitable cationic surfactants are the chlorides or bromides of alkyldimethylbenzylammonium salts, alkyltrimethylammonium salts, for example cetyltrimethylammonium chloride or bromide, tetradecyltrimethylammonium chloride or bromide, alkyldimethylhydroxyethyϊammoniumchloride or bromide, for example, dialonyl bromide, pyridium bromide, or dialkyldomidium, or bromide, dialkyldomidium, or bromide, dialkyldomidium, or bromide, for example, or cetylpyridinium chloride, alkylamidoethyltrimethylammonium ether sulfates and compounds with a cationic character such as amine oxides, for example alkylmethylamine oxides or alkylaminoethyldimethylamine oxides. Cetyltrimethylammonium chloride is particularly preferred. Suitable cationic surfactants are also the so-called esterquats, for example C8 to C18 alkyl esters of betaine, for example palmityl betaine chloride.

Suitable anionic surfactants are selected from

Alkali or alkaline earth metal salts of the CIO to C18 alkyl sulfates, the CIO to C18 alkyl sulfonates, the CIO to C18 alkyl benzene sulfonates, the CIO to C18 xylene sulfonates and the CIO ethoxylated with 1 to 10 ethylene oxide units - to C18-alkyl ether sulfates, the ethoxylated sulfosuccinic acid semiesters of the formula R- (OCH ₂ CH ₂ ) _m -0 ₂ C-CH ₂ -CH (S0 ₃ M) -COOM where R is a C10- to C18-alkyl radical, M represents an alkali or alkaline earth metal cation and m represents a number from 1 to 10 and the alkyl ether carboxylates of the general formula

The agents have the advantage that they are easy to distribute on the hair, are easy to apply even on inclined surfaces, do not run off and do not drip. The coloring result of the colorants according to the invention is at least equivalent to that of a conventional, non-foamed colorant when using the same volumes per application. This means a significant cost saving, since with the colorants according to the invention, less dye is used per application due to the reduced density than when using conventional, non-foamed products.

Examples

Example 1: Hair dye cream

A dispersion is produced from the following components:

14.5 g cetearyl alcohol

5.0 g glyceryl stearate 2.8 g sodium lauryl ether sulfate

2.0 g of glycol distearate

1.93 g ammonia

1.84 g lanolin alcohol

1.61 g sodium lauryl sulfate 0.6 g 2,5-diaminotoluenesulfate

0.46 g sodium cocoyl isethionate

0.4 g isopropanol

0.4 g sodium sulfite

0.3 g ascorbic acid 0.29 g resorcinol

0.1 g disodium EDTA

0.03 g of 6-amino-m-cresol

0.03 g of 2-methylresorcinol

Ad 100 g water The homogenization is carried out with a commercially available homogenizer. At 35 ° C, compressed air was introduced into the suction with the homogenizer running (2600 rpm) and finely distributed by the homogenization. The density of the coloring mass drops from 0.985 g / ml to 0.853 g / ml after 4 minutes of air entry. The degree of foaming is 15.5%. The foamed product has a more cosmetic, pleasant impression. The mass is lighter and softer. Coloring on strands of hair with an oxidizing agent provides the same good coloring result as the non-foamed cream when using the same volumes and therefore lower amounts of dye. A separation or enlargement of the air bubbles was not found even after several days.

Example 2: Hair dye cream

A dispersion is produced from the following components:

5.0 g stearyl alcohol

5.0 g petrolatum

3.8 g glyceryl stearate

2.5 g cetyltrimethylammonium chloride

1.5 g isopropanol

0.95 g ethanol

0.2 g ceteareth-20

0.07 g Basic Blue 7

0.045 g Basic Violet 14 q.s. Preservative, perfume

Ad 100 g water

The homogenization is carried out with a commercially available homogenizer. At 50 ° C with a slight vacuum (0.8 bar abs.) Compressed air (2.5 bar abs.) into the suction while the homogenizer is running (2700 rpm) and finely distributed by the homogenization. The suction time is 1 min. The density of the coloring mass drops from 0.966 g / ml to 0.750 g / ml with unchanged viscosity. After 4 weeks of storage at 20 ° C, only very slight changes can be determined, the density is then 0.795 g / ml and the degree of foaming is 21.5%.

Coloring on strands of hair provides an equally good

Coloring result like the non-foamed cream when using the same volumes and therefore lower amounts of dye.
