Abstract

Hair preparations containing a conditioning care component comprising dimethicone or dimethiconol and a mixture of MIPA-Laureth Sulfate, Laureth-4 and Propylene Glycol.

Description

Hair washing plays a central role in human body care. The cleaning of the hair and scalp of the body's own fat, Hautabschilferungen, dirt and odors meets a basic need of man.

The hair consists of a hair shaft that protrudes freely from the skin. The hair shaft is keratinized (dead) and is the visible part of the hair. The invisible hair root is the living part and localized in the skin. The hair is formed in the hair root. The hair shaft is composed of three layers: a central part, the so-called Haarmark (medulla), which is regressed in humans and often completely absent, the marrow (cortex) and the outer, up to ten layers strong, cuticle (cuticle), which covers the whole hair.

Until the 20th century, soap was used to cleanse people, and also to cleanse their hair. However, soap is poorly tolerated by the scalp and ocular mucosa due to its alkaline pH. There are often left deposits of lime soap in the hair. In the thirties of the 20th century, the first alkyl sulphate shampoos were launched. Since the mid-sixties, alkyl ether sulfates and other surfactants are preferably incorporated into shampoos. With them, the disadvantages of soap-containing preparations can be avoided. Nowadays, modern shampoos not only have to cleanse the hair and be well-tolerated, they are also designed to nourish and enhance hair styling and visual attractiveness.

Hair shampoos contain a variety of different components to meet the individual product requirements:
Surfactants, such as anionic, amphoteric and nonionic surfactants, are surface-active compounds. These substances are responsible for the cleaning performance of shampoo preparations. Surfactants also ensure the foaming power of the hair cleanser. In addition, their insensitivity to water hardness, their biodegradability, their compatibility with other components of the preparation, and their price are important in the selection of surfactants. For example, a widely used shampoo surfactant is alkyl ether sulfate.

In addition, shampoos contain a number of consistency regulators (hereinafter referred to as thickeners), which give the preparation the desired viscosity. These thickeners cause an enlargement of the surfactant micelles or a swelling of the water phase of the preparation. Thickeners can be selected from chemically very different substance classes. So u. a. Electrolytes (eg sodium chloride), alkanolamides (for example fatty acid monoethanolamides), low ethoxylated fatty alcohols (eg diethylene glycol monolauryl ether), highly ethoxylated ethers, esters and diesters and also polymeric thickeners. The polymeric thickeners include, for example, cellulose ethers. In addition, polyacrylates and hydrocolloids are also used as thickeners.

Hair shampoos are also added different types of drugs. In addition to UV absorbers, vitamins or plant extracts, these also include so-called hair conditioners (English conditioner), which maintain the hair, improve its combability and grip, and increase its gloss. Conditioners, unlike most other shampoo ingredients, will attract hair and stay there after rinsing. This means that conditioners can form a film on the hair surface. For example, due to their molecular structure, they can attach to the damaged areas of the cuticle of the hair and thereby smooth the hair. In this way, the hair is less rough and brittle, it is easier to comb; In addition, the hairstyle gets much more shine. Also, the hair becomes less sensitive to electrostatic charging. One group of hair-conditioning substances are the cationic surfactants. Another group of hair-conditioning substances are, for example, polymeric quaternary ammonium compounds, generally in the form of cationic polymers. It is also possible to use cationic cellulose derivatives and polysaccharides. An important group of hair conditioning substances are silicone compounds. They are particularly useful in shampoo formulations because no adverse interactions with the commonly used anionic surfactants are observed.

Silicones also have the chemical name poly (organo) siloxanes. It is a group of synthetic polymers in which silicon atoms are linked via oxygen atoms. Silicones consist of individual siloxane units consisting of silicon atoms connected via an oxygen bridge.

The general formula is R _n SiO _{(4-n) / 2} (n = 0, 1, 2, 3), ie, a siloxane unit may have a further one to four substituents.
Siloxane units can therefore be mono-, di-, tri- and tetrafunctional. In symbolic notation, this is represented by the following letters:
M (mono), M corresponds to R ₃ SiO _1/2 ,
D (di), D corresponds to R ₂ SiO _2/2 ,
T (tri), T corresponds to RSiO _3/2 and
Q (quatro), Q corresponds to SiO _4/2 .

• • Cyclische Polysiloxane sind ringförmig aus difunktionellen Siloxaneinheiten aufgebaut, D_n.
• • Lineare Polysiloxane sind folgendermaßen aufgebaut MD_nM, bzw. R₃SiO[R₂SiO]_nSiR₃, als Beispiel sei Polydimethylsiloxan genannt.
• • Vernetzte Polysiloxane sind ketten- oder ringförmige Moleküle, die mit Hilfe von tri- und tetrafunktionellen Siloxaneinheiten zu ebenen oder dreidimensionalen Netzwerken verknüpft sind. Der Aufbau hochmolekularer Silikone erfolgt über Kettenbildung und Vernetzung.
• • Verzweigte Polysiloxane weisen als verzweigende Elemente trifunktionelle oder tetrafunktionelle Siloxaneinheiten auf, M_nD_mT_n. Die Verzweigungsstellen sind dabei entweder in eine Kette oder einen Ring eingebaut.

As with organic polymers, the multitude of possible compounds is based on the fact that different siloxane units can be linked together in the molecule. Based on the systematics of organic polymers, the following groups can be distinguished:

• • Cyclic polysiloxanes are ring-shaped from difunctional siloxane units, D _n .
• • Linear polysiloxanes are constructed as follows MD _n M, or R ₃ SiO [R ₂ SiO] _n SiR ₃ , as an example polydimethylsiloxane mentioned.
• • Crosslinked polysiloxanes are chain or ring-shaped molecules linked to flat or three-dimensional networks by means of tri- and tetrafunctional siloxane units. The construction of high molecular weight silicones occurs via chain formation and crosslinking.
• Branched polysiloxanes have as branching elements trifunctional or tetrafunctional siloxane units, M _n D _m T _n . The branching points are installed either in a chain or a ring.

Silicones can be further classified according to the substituents attached to the silicon atom.

Silicones frequently used in hair preparations are, for example, amodimethicones. These are polydimethylsiloxanes having one terminal aminoalkyl group, ie cationic silicone polymers. Amodimethicones adhere well to proteins. This leads to an improvement in combability when this class of substance is used in hair conditioners or conditioners.

Stearyl methicones are dimethylpolysiloxanes in which a methyl group has been completely replaced by a specific alkyl radical, here stearyl radical. They have a waxy consistency and are used as bodying agents.

Cyclomethicones are silicone oils with a ring structure. They are practically insoluble in water. The name cyclomethicone refers to various dimethylpolysiloxanes, the best known are cyclopentasiloxanes (10-membered ring, 5 silicon atoms and 5 oxygen atoms), cyclotrisiloxanes (6-membered ring, 3 silicon atoms and 3 oxygen atoms) and cyclotetrasiloxanes (8-membered ring, 4 silicon atoms and 4 oxygen atoms). These are colorless, low-viscosity and (weakly) volatile liquids. Cyclomethicones have a spreading effect. They are often used together with highly viscous silicones. They reduce the stickiness and improve the skin feel. In hair care products, they act as conditioners to improve the combability and shine of the hair.

Dimethicones belong to the group of silicone oils. They cover a wide range of viscosity, from volatile to highly viscous. Linear polydimethylsiloxanes, polymers with different molecular sizes, are virtually water-insoluble, clear, colorless and odorless liquids. The simplest representative, the hexamethyldisiloxane, is used in hair care products to improve combability, as a conditioner and to increase the shine of the hair. The liquid and volatile dimethicones are spreaders and plasticizers, they are used to improve the wet combability of the hair.

Dimethiconol has hydroxyl groups. As a result, the silicone molecule obtains polar properties, whereby a good adhesion to the hair is achieved. Dimethiconol is highly viscous and is therefore often used together with the low-viscosity cyclopentasiloxane for hair conditioning, especially in hair tip fluids and as an anti-foaming agent.

Hydroxypropyl dimethicone, a dimethylpolysiloxane with partial, functionalized alkyl groups, has conditioning properties and hair fixing properties.

Phenyl Methicone contains methyl and phenyl groups. In addition to conditioning properties, these compounds also have a positive influence on the luminosity of the hair.

Phenyl Trimethicone is a silicone oil that improves combability and also acts as an antistatic agent, emollient and antifoam agent.

The hair preparations according to the invention, in particular the hair shampoos, may advantageously have a content of linear silicone oils. According to the invention, it is advantageous to use polydimethylsiloxanes. The polydimethylsiloxanes preferred according to the invention can be characterized by their viscosity values. Likewise, molecular weight is one way of characterizing the preferred polydimethylsiloxanes.

Dimethiconols can also be incorporated advantageously into the preparations according to the invention. Dimethiconols contain hydroxyl groups and are therefore well suited to adhere to the hair surface. Dimethiconols can also be characterized by their viscosity and their molecular weight.

The use of various silicones in hair preparations, even in shampoo preparations, is known per se. By way of example, the following documents of the prior art are listed.

DE 4229922 discloses conditioners for hair containing quaternary ammonium compounds and alkyl polyglucosides non-volatile silicones. These silicones may be dimethicones or dimethiconols. However, there is no disclosure for adjusting certain viscosity values in the preparations.

DE 10 2005 049 493 discloses surfactant-containing cleaning formulations containing a water-insoluble silicone component. These cleaning preparations are stabilized with the aid of hardened castor oil. There is no description of other stabilizing substances.

However, the use of dimethicones or dimethiconols, the preferred care components in the present invention lead to products according to the invention having too low a viscosity and thus being too thin. Such products are hardly accepted by the customer.

The object of the present invention was to provide products containing dimethicones or dimethiconols, which have a sufficient viscosity to no longer be perceived by the customer as having low viscosity. The viscosity values of the final product should be ≥ 3000 mPa · s.

In addition, the products according to the invention should link to the care performance of shampoos already on the market, containing comparable silicone compounds, ideally having improved care performance.

Surprisingly, the above objects are achieved by the use of selected thickeners. It has been found that the sole use of thickeners of the prior art, such as NaCl or cocamide DEA, did not lead to satisfactory products.
Therefore, the abovementioned objects are achieved by hair preparations, in particular hair shampoo preparations and, in particular, hair shampoo care preparations containing
at least one anionic surfactant,
at least one amphoteric surfactant,
at least one conditioning care component comprising dimethicone or dimethiconol and
a blend of MIPA Laureth Sulfate, Laureth-4 and Propylene Glycol.

It was not foreseeable by those skilled in the art that an anhydrous mixture of MIPA-Laureth Sulfate, Laureth-4 and Propylene Glycol, which is normally used as a surfactant mixture for anhydrous oil baths or oil showers, develops a thickening effect in the formulations according to the invention. In this way, preparations having the desired viscosity values (3000 to 6000 mPa.s) could be made available.

The present invention also provides for the use of a mixture of MIPA-Laureth Sulfate, Laureth-4 and Propylene Glycol for setting a viscosity of 2000 to 8000 mPa · s, preferably from 3000 to 6000 mPa · s in the hair formulations according to the invention, wherein the viscosity measurement with a Rheomat R 123, measuring body 1 at 25 ° C.

Likewise provided by the present invention is the use of a mixture of MIPA-Laureth Sulfate, Laureth-4 and Propylene Glycol, to increase the care performance in hair shampoo preparations.

According to the invention, it is preferred if the anionic surfactants, which mainly contribute to the cleaning action in the preparations according to the invention, are selected from the group alkyl sulfates and alkyl ether sulfates, it is particularly preferred if the anionic surfactants are alkyl ether sulfates. It is further preferred if the anionic surfactant is sodium laureth sulfate. The anionic surfactants are present with active contents of 1.0 to 20.0 wt .-%, preferably 5.0 to 15.0 wt .-% and particularly preferably with a content of 8.0 to 12.0 wt .-%, based on the total content of the preparation. These contents do not include the content of MIPA-Laureth Sulfate, the anionic surfactant in the thickener mixture.

As amphoteric surfactants, preference is given to surfactants which contain betaine as the basic substance, for example alkylbetaines and / or alkylamidopropylbetaines. It is particularly preferred if the amphoteric surfactant is a cocoamidopropyl betaine.

The amphoteric surfactants are present with an active content of 0.1 to 10 wt .-%, preferably 0.5 to 5.0 wt .-%, particularly preferably 1.0 to 3.0 wt .-%, based on the total weight of Preparation before.

It is preferred if the dimethicones are selected from dimethicones having a viscosity of from 50 to 100,000 mPa.s, preferably from 1,000 to 50,000 mPa.s, very particularly from 6,000 to 20,000 mPa.s, these viscosity data being based on the viscosity of the raw materials refer to manufacturer's instructions. A dimethicone compound which is advantageous according to the invention is obtainable, for example, from Dow Corning under the trade name Xiameter MEM-7139 emulsion. The dimethicones which are suitable according to the invention are used in active concentrations of from 0.1 to 15.0% by weight, preferably from 0.5 to 10.0% by weight, particularly preferably from 1.0 to 5.0% by weight, based on Total weight of the preparation used.

It is preferred if the dimethiconols are selected from dimethiconols having a viscosity of from 1 to 1000 mPa.s, preferably from 2 to 100 mPa.s, very particularly from 5 to 75 mPa.s, these viscosity data being based on the viscosity of the raw materials refer to manufacturer's instructions. A dimethiconol compound which is advantageous according to the invention is obtainable, for example, from Momentive under the trade name Silsoft EM-160 A. The dimethiconols which are suitable according to the invention are in active concentrations of 0.05 to 15.0% by weight, preferably 0.1 to 7.5 Wt .-%, particularly preferably 0.2 to 5.0 wt .-%, based on the total weight of the preparation used.

The hair formulations of the invention may also contain polymeric quaternary ammonium compounds. Preference is given to hair conditioning substances in the form of cationic polymers. Examples of these are cationic cellulose derivatives, preferably polyquaternium-10 and polysaccharides.

As a thickener according to the invention, a combination of MIPA-Laureth Sulfate, Laureth-4 and Propylene Glycol is used, with MIPA-Laureth sulfates having 25 to 47.5% by weight, laureth-4 having 25 to 47.5% by weight. % and propylene glycol are contained at 1 to 5% by weight. Such a combination is available, for example, from Zschimmer & Schwarz under the trade name Lumerol K 5229. The MIPA-Laureth Sulfate contained in the thickener according to the invention is in active contents of 0.2 to 10.0 wt .-%, preferably from 0.5 to 5.0 wt .-%, particularly preferably from 0.75 to 2.5 wt .-%, based on the total weight of the preparation before.

The hair preparations according to the invention may contain anti-dandruff agents. From the literature, a variety of antimycotically active substances is known which can be used as anti-dandruff agents in cosmetic formulations. These include u. a. Climbazole, ketoconazole, ciclopirox, piroctone oilamines, zinc pyrithione and selenium disulfide. Climbazole, in particular, is known as an antifungal agent and is often used in anti-dandruff products. The incorporation of climbazole into cosmetic or dermatological preparations can be improved by Laureth-9. Anti-dandruff agents preferred according to the invention are piroctone oleamines or climbazole or a combination of both anti-dandruff agents. The antidandruff agents are present at levels of 0.1 to 2.0% by weight, preferably 0.4 to 1.0% by weight, based on the total weight of the preparation.

The preservation of the preparations according to the invention can be carried out in the manner customary for cosmetic preparations. However, preference is given to preserving with benzoic acid and / or a salt of benzoic acid, with salicylic acid and / or a salt of salicylic acid and / or with sorbic acid and / or a salt of sorbic acid. Particularly preferred is the preservation with sodium benzoate. The preferred preserving substances are present at levels of from 0.1 to 1.0% by weight, preferably from 0.3 to 0.6% by weight, based on the total weight of the preparation.

The adjustment of the pH can be carried out in a manner customary for cosmetic preparations. However, preference is given to adjusting the pH with citric acid.

The viscosity of the hair preparations was measured using Rheomat R 123. Measuring body 1 was used. The device is a rotational viscometer in which a motor rotates a body in a liquid. While turning, the required torque is measured. From this, as well as from the exact geometry of the rotating body used and the outer vessel, as well as the rotational speed, the dynamic viscosity of the liquid can be determined. Viscosity measurements were made at 25 ° C.

In order to prove that the preparations according to the invention have an improved care performance compared with the preparations of the prior art, half-side tests were carried out in the hair studio. For this, the hair is divided into two equal halves. One half is treated with a preparation according to the invention, the other half with a comparative preparation. The comparative preparation contained no thickener according to the invention, but Cocamide DEA, a thickener which can be used according to the prior art as a thickener of silicone-containing hair preparations. 1a shows that formulations according to the invention containing dimethicones and the thickener according to the invention, a mixture of MIPA-Laureth sulfates, laureth-4 and propylene glycol (Example 4) performs better than the comparative example (Example 8) in all the parameters investigated. It turns out that after application of the product according to Example 4 improved Pfegeleistung is achieved. The difference in the parameters of lubricity during rinsing and in dry hair, as well as structure of wet hair is significant. The difference is 0.5 - 1.0 point on the tens scale. Despite the same amount of care substances, here dimethicones, Example 4 has a significantly higher care performance than Example 8. Since the formulas differ significantly by the thickener, the thickener according to the invention can be regarded as essential for improving the care performance.

1b shows the results of an identically constructed experimental batch, but a product according to Example 3 was used as a shampoo according to the invention. Example 3 differs from Example 4 in that the dimethicone amount is significantly reduced by 25%. The differences in the care performance are not significant in this comparison, but at most for an expert felt. It is with the help of the thickener of the invention, the mixture of MIPA-Laureth Sulfate, Laureth-4 and propylene glycol, so possible to achieve the same care performance as a comparison shampoo with Cocaraid DEA thickener, saving 25% silicone.
