Description

Hair shampoo with improved care performance containing silicones

Hair washing plays a central role in human body care. The

Cleaning the hair and scalp of the body's own fat, Hautabschilferungen, dirt and odors meets a basic need of humans.

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, however, and often completely absent, the medulla (cortex) and the outer, up to ten layers thick, cuticle layer

(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 deposits of

Lime soaps in the hair back. 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

Responsible for shampoo preparations. In addition, surfactants provide for that

Foaming power of the hair cleanser. In addition, their insensitivity to water hardness, their biological properties, are important in the selection of surfactants Degradability, its compatibility with other components of the preparation, as well as their price. 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 (e.g., sodium chloride), alkanolamides (e.g., fatty acid monoethanolamides), low ethoxylated fatty alcohols (e.g.

Diethylene glycol monolauryl ether), highly ethoxylated ethers, esters and diesters and polymeric thickeners used. 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 also include so-called hair conditioner (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 RnSiO ₍₄ -n) / 2 (n = 0, 1, 2, 3), ie a siloxane unit may have one to four further substituents.

Siloxane units can therefore be mono-, di-, tri- and tetrafunctional. In symbolic

Notation is represented by the following letters:

M (mono), M corresponds to R3S1O1 / 2,

D (di), D corresponds to R2S1O2 / 2,

T (tri), T corresponds to RS1O3 / 2 and

Q (quatro), Q corresponds to S1O4 / 2.

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, for example polydimethylsiloxane.

• 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 trifunctional or branching elements

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, if this substance class in hair rinses or

Conditioners is used. 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 denotes various dimethylpolysiloxanes, the best known are cyclopentasiloxanes (1 Oer ring, 5 silicon atoms and 5 oxygen atoms),

Cyclotrisiloxane (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 (low) volatile liquids. Cyclomethicones have a spreading effect. They are often used together with highly viscous silicones. They reduce that

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

Viscosity range from volatile to highly viscous. Linear polydimethylsiloxanes, polymers of different molecular sizes, are virtually water insoluble, clear, stain 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 becomes 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.

Advantageously, the hair preparations according to the invention, in particular the

Hair shampoos containing a content of linear silicone oils. According to the invention, it is advantageous to use polydimethylsiloxanes. The inventively preferred

Polydimethylsiloxanes can be characterized by their viscosity values. Likewise, molecular weight is one way of adding the preferred polydimethylsiloxanes

characterize.

Dimethiconols can also be used advantageously in the preparations according to the invention

be incorporated. Dimethiconols contain hydroxyl groups and are therefore well suited to adhere to the hair surface. Dimethiconols can also be used over their

Viscosity and its molecular weight can be characterized.

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

DE 4229922 discloses conditioners for hair, in addition to quaternary

Ammonium compounds and alkyl polyglucosides contain nonvolatile silicones. These silicones may be dimethicones or dimethiconols. However, there is no disclosure for adjusting certain viscosity values in the preparations.

DE 102005049493 discloses surfactant-containing cleaning preparations which have a

water-insoluble silicone component included. These cleaning preparations are stabilized with the aid of hardened castor oil. There is no description to others

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, in order to no longer be perceived as fluid at the customer. 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 dimethicones 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, exerts a thickening effect in the formulations according to the invention. In this way preparations with the desired viscosity values (3000 to 6000 mPa s) could be made available.

The present invention also relates to 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 inventive

Hair preparations, wherein the viscosity is measured 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 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 Preparation before. In these levels is the content of MIPA-Laureth Sulfate, the

anionic surfactant not included 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 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 the preparation before.

It is preferred if the dimethicones are selected from dimethicones having a viscosity of from 50 to 100,000 mPas, preferably from 1,000 to 50,000 mPas, more particularly from 6,000 to 20,000 mPas, these viscosity data being based on the viscosity of the raw materials Refer to manufacturer's specifications. An inventively advantageous

Dimethicone compound is available, for example, from Dow Corning under the tradename Xiameter MEM-7139 emulsion. The Dimethicone suitable according to the invention are in active concentrations of 0, 1 to 15.0 wt .-%, preferably 0.5 to 10.0 wt .-%, particularly preferably 1, 0 to 5.0 wt .-%, based on the 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 according to the manufacturer's instructions Respectively. 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 described in US Pat

Active concentrations of 0.05 to 15.0 wt .-%, 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.

The inventive thickener used is a combination of MIPA-Laureth Sulfate, Laureth-4 and Propylene Glycol, MIPA-Laureth sulfates having from 25 to 47.5% by weight, laureth-4 having from 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 antimycotic substances is known, which as

Antidandruff agents can be used in cosmetic formulations. These include u.a. Climbazole, ketoconazole, ciclopirox, piroctone olamine, 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. According to preferred antidandruff agents are Piroctone olamine or climbazole or a

Combination of both anti-dandruff agents. The antidandruff agents are present at levels of from 0.1 to 2.0% by weight, preferably from 0.4 to 1.0% by weight, based on the

Total weight of the preparation, before.

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 a preservation 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 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 by means of 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.

Uni to prove that the preparations according to the invention have improved care performance compared to the preparations of the prior art have been

Half-side experiments performed 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.

The shampoo according to the invention (Example 4) was tested in half-side comparison in the hair studio at 10 subjects of experts. A comparison was made of a silicone shampoo thickened with cocamide DEA (without thickener according to the invention, Example 8). At the

Half-side comparison, the hair is divided into a left and a right half. One side is treated with the shampoo according to the invention, the other with the

Compare shampoo. The rating was made by experts on the basis of a scale of ten.

Shown are the mean values from the expert evaluations of the 10 subjects.

FIG. 1 a shows that preparations according to the invention comprising dimethicones and the thickener according to the invention, a mixture of MIPA-Laureth sulfates, laureth-4 and propylene glycol (Example 4) performed better in all investigated parameters than the comparative example (Example 8). 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. FIG. 1 shows the results of an identically designed experimental batch, but a product according to Example 3 was used as the shampoo according to the invention. Example 3 differs from Example 4 in that the dimethicone amount is significantly reduced by 25%.

The shampoo according to the invention (Example 3), which contains 25% less dimethicones than Example 4, was also evaluated in a half-page comparison in the hair studio on 10 test persons from experts. As a comparison served with cocamide DEA thickened silicone shampoo (Example 8, without inventive thickener).

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, with the saving of 25% silicone, the same care performance as in a

Comparative shampoo with cocamide DEA to achieve thickener.
