Use of organomodified siloxane block copolymers as a care active substance for the care of human or animal body parts

Field of the invention

The present invention relates to the use of organomodified Siloxanblockcopolymere as Pflegewirk- substance for the care of human or animal body parts.

State of the art

Organomodified siloxanes are used in a wide variety of applications. Their properties can be adjusted, among other things, by the type of modification as well as by the modification density.

Thus, for example, organophilic or non-reactive hydrophilic groups can be bound to a silicon moiety with allyl polyethers. Such compounds are used, for example, as polyurethane foam stabilizers, as defoamers in fuels or as additives in paints and coatings.

Thus, e.g. DE 102005001041 functionalized polyorganosiloxanes and their use as fuel defoamers. Optionally, the allyl polyethers in the siloxanes represented herein may be replaced by modification of the hydrocarbon radical synthesis.

In general, siloxanes can be linked by reaction with, for example, α-olefins with hydrophobic groups. The Silicone waxes obtained in this way are used, for example, as an additive in personal care applications.

It is evident in many fields of application that the effect of the siloxane depends decisively on the compatibility with the corresponding formulation.

Suitable as a cosmetic emulsifier are, for example, siloxanes which carry polyethers in addition to aliphatic groups based on α-olefins. A typical example of this is the sales product ABIL EM 90 from Evonik Goldschmidt GmbH (Germany), which is characterized in particular by excellent stabilization of water-in-oil (W / O) emulsions.

EP 1125574 describes the use of relatively hydrophobic polyether siloxanes as O / W emulsifiers in which the polyether groups are α-ω or terminal siloxane backbones. These structures are characterized in particular by a velvety silky feel on the skin, which they are able to incorporate into cosmetic emulsions.

US 5474712 describes the use of prior art polyethersiloxanes in animal conditioning shampoos.

WO 02/053111 describes the use of silicone polyether block copolymers with (AB) _n structures in aqueous, surface-active body cleansing compositions which have good cosmetic properties especially for the volume, combability and shine of hair. No. 5,879,671 describes the use of aqueous, surface-active body cleansing compositions containing mixtures of amino-functional siloxanes and polyethersiloxanes according to the prior art as care active ingredient. These mixtures cause a permanent improvement of the dry and wet combability of the hair.

DE 19603357 describes the use of polyether-modified MQ resins (polyetherdimethylsiloxysilicate) in cosmetic formulations as care active ingredients. These cause a promotion of the gloss and the retention of curls.

As a care active substance for hair and skin are in the article "Les Copolymeres Polysiloxanes polyethers comme additifs dans les formulations cosmetiques" (Dr. Kollmeier, perfumes, cosmetiques, aromes; 51; 1983; 67-72) siloxanes, the polyether groups and / or worn sideways, described.

Commercially available siloxane-based skin care ingredients are, for example, ABIL B 8842, ABIL B 88183 and ABIL B 8832

(Evonik Goldschmidt GmbH), Belsil DMC 6031, Belsil DMC 6032 and Belsil DMC 6033 (Wacker-Chemie). The sales product ABIL B 8832 (Evonik Goldschmidt GmbH) is a siloxane modified laterally with polyether groups, which is used as a care agent for hair and skin in surfactant solutions and nourishing cosmetic formulations. The laterally modified with polyether groups siloxanes are a powerful class of care agents that cause a pronounced conditioning effect on skin and hair from cosmetic formulations. Further, these pendant siloxanes have lather enhancing properties. Shanks. However, the lateral polyethersiloxanes have the disadvantage that they have a strong viscosity-reducing effect even at low use concentrations.

Examples of moderately polyether-modified siloxanes are ABIL B 8851 and ABIL B 8842 (Evonik Goldschmidt GmbH). These effect a less pronounced conditioning effect on the skin and hair from cosmetic, aqueous, surface-active formulations in comparison with the silicones which have been modified with polyether groups and have been modified laterally. Furthermore, these moderately modified with polyether groups siloxanes also have the disadvantage of having viscosity-lowering properties.

An object of the present invention was therefore to provide organomodified siloxanes which overcome the aforementioned disadvantages of the prior art as a care active ingredient.

Description of the invention

It has surprisingly been found that the use of organomodified siloxane block copolymers, prepared by a process described in claim 1 as a care active substance for the care of human or animal body parts, is capable of accomplishing this task.

The invention therefore relates to the use of organomodified siloxane block copolymers, prepared by a process described in claim 1 as care active ingredient for the care of human or animal Body parts, the formulations themselves and the use of this formulation in, for example, cosmetic applications.

Advantages of the use according to the invention are that the siloxanes, as powerful care active ingredients, have a pronounced conditioning effect on the skin and hair and can be used in aqueous, surface-active formulations, in particular in liquid body cleansing compositions, for example shower baths and hair shampoos, without a significant lowering of the Viscosity of the aqueous, surfactant formulation occurs.

Another advantage is that the siloxanes used are easy to process because they are liquid or easily liquefied at room temperature and can be combined with conventional ingredients of aqueous, surfactant formulations.

A further advantage is that the use according to the invention as care active ingredient contributes to improved foaming behavior, increased foam volume and better foam creaminess of the formulations.

A particular advantage of the use according to the invention is the excellent conditioning effects on the skin and hair of the care active ingredient. By means of this conditioning effect on, for example, the skin, a dry, brittle or rough condition of the skin after application of an aqueous, surfactant formulation can be prevented and a pleasant, velvety-silky skin feeling is achieved. Another advantage of the invention is that due to the reduced viscosity-lowering property, a significant reduction in required thickeners to adjust the formulation to the desired viscosity is achieved. This makes it possible to simplify the formulations, which take into account the resource-conserving aspect.

The invention is described below by way of example, without the invention being limited to these exemplary embodiments.

For the purposes of the invention, "aqueous formulations" are to be understood as meaning formulations containing, based on the total mass, at least 30% by mass, preferably at least 60% by mass, more preferably at least 80% by mass of water.

For the purposes of the invention, "aqueous, surface-active formulations" are to be understood as meaning formulations containing, based on the total mass, less mass percent of the oil component than the sum of the mass percentages of emulsifier, surfactant and, if appropriate, co-emulsifier.

Tab.l: Comparative Examples 5 to 7.

Comparative Example 5 corresponds to a side-by-side polyethersiloxane of the prior art.

Comparative Examples 6 and 7 correspond to prior art mediocre polyethersiloxanes.

Application examples:

All concentrations in the application examples are given in percent by weight. For the production of Formulations were used the usual formulation methods known to those skilled in the art.

Viscosity effect: To check the viscosity effects of the organomodified siloxane block copolymers 1 to 4 according to the invention and the polyethersiloxanes according to the prior art 5 to 7, these compounds were converted into a surfactant system with a conventional thickener Antil 171, Evonik Goldschmidt GmbH (INCI: PEG-18 Glyceryl Oleate / Cocoate ) tested.

The formulations were stored after preparation for 24 hours at 25 ⁰ C and then the viscosity using a Brookfield viscometer (Brookfield LVF, spindle 3, 5 rpm) at 25 ⁰ C measured.

As control formulation Oa, a formulation without the addition of a polyethersiloxane is used.

The results of the formulations Ia, 2a, 3a and 4a with the organomodified siloxane block copolymers according to the invention care active ingredients 1 to 4, the formulations V5a, V6a and V7a with the polyethersiloxanes according to the prior art 5 to 7 and the control formulation 0a without polyethersiloxane (test formulation) are summarized in Table 2. Tab.2: Measured viscosities when using PEG-18 Glyceryl Oleate / Cocoate (Antil 171, Evonik Goldschmidt GmbH) for thickening the aqueous, surfactant formulation.

In the comparative formulations V5a, V6a and V7a, according to the prior art, however, there is a strong decrease in the viscosity in comparison to the control formulation 0a.

2.) Testing the conditioning of skin (skin care performance) and foam properties by means of a hand wash test:

To assess the conditioning of skin (skin care performance) and the foam properties of the inventive organomodulated Siloxanblockcopolymeren care active 1 to 4 in aqueous, surfactant formulations sensory hand washing tests were performed in comparison to the comparative examples 5 to 7 according to the prior art.

Comparative Examples 5 to 7 are widely used in industry as care active ingredients and are considered to be highly effective P f 1 e w e r k s t o f f e in aqueous, surface-active formulations.

A group of 10 trained test persons washed their hands and evaluated foam properties and skin sensation on the basis of grades ranging from 1 (poor) to 5 (very good). The used products were each tested in a standardized surfactant formulation (Table 3).

As a control formulation Whether a formulation without the addition of a polyethersiloxane is used.

Tab.3: Test formulations for hand washing test. The sensory test results are summarized in Table 4.

Tab.4: Results of the hand wash test

Table 4 shows the results of the hand wash test. Based on the measurement results, it can be seen that the inventive formulations Ib to 4b using the organomodified SiI oxanblockcopolymeren 1 to 4 according to the invention better skin smoothness and skin softness 3 minutes after application and a superior skin feel during washing compared to the comparative formulations V5b, V6b and V7b effect according to the prior art. The skin smoothness and skin softness directly after the application is also the same or superior to the measured values in the formulations according to the invention Vb, V6b and V7b in the formulations Ib to 4b according to the invention. Furthermore, it can be seen from the measurements that the pendant polyethersiloxane (Comparative Formulation V5b) is superior to the mediocre polyethersiloxanes (Comparative Formulations V6b and V7b) in skin conditioning.

Against this background, the results of the formulations Ib to 4b according to the invention are very good. Furthermore, based on the measured values it can be seen that the organomodified siloxane block copolymers 1 to 4 according to the invention in the formulations Ib to 4b bring about an improvement in the foaming properties, in particular the foaming creaminess.

3.) Hair conditioning by means of sensor tests:

For the performance assessment of the conditioning of hair, the organomodified siloxane block copolymers 1 and 2 according to the invention and the comparative product 5 were used in simple cosmetic formulations (shampoo and hair conditioner).

The application properties when used in a shampoo were tested in the following formulations:

Tab.5: Shampoo formulations for testing hair conditioning properties.

To evaluate the properties of the shampoo formulation, no post-treatment with a rinse was carried out in the test procedure.

The application properties when used in hair rinses were checked in the following formulations:

Tab.6: Hair conditioner Formulations for testing hair conditioning properties.

The pretreatment of the hair takes place in the case of property testing of hair rinses by a shampoo containing no conditioning agent. For the performance assessment, hair tresses used for sensory tests are predamaged in a standardized way by a permanent wave treatment and a bleaching treatment. For this purpose, hairdressing customary products are used. The test procedure, the basic materials used and the details of the evaluation criteria are described in DE 103 27 871.

Standardized treatment of previously damaged hair strands with conditioning samples:

The hair tresses previously damaged as described above are treated with the above-described shampoo or conditioner as described above:

The strands of hair are moistened under running, warm water. The excess water is gently squeezed out by hand, then the shampoo is applied and gently incorporated into the hair (1 ml / strand of hair (2 g)). After a residence time of 1 min, the hair is rinsed for 1 min.

If necessary, the rinse is immediately applied and gently incorporated into the hair (1 ml / strand of hair (2 g)). After a residence time of 1 min, the hair is rinsed for 1 min.

Before the sensory evaluation, the hair is dried in air at 50% humidity and 25 ⁰ C for at least 12 h.

Assessment criteria:

The sensory evaluations are based on grades awarded on a scale of 1 to 5, where 1 is the worst and 5 is the best rating. The individual test criteria each receive their own rating.

The teats are: wet combed, wet grip, dry combability, dry grip, appearance / shine.

The following table compares the results of the sensory evaluation of hairline treatment as described above with formulations Ic and 2c according to the invention, comparison formulation V5c and control formulation Oc (placebo without test substance).

Tab.7: Results of conditioning hair from shampoo formulation

The results show, surprisingly, that the inventive formulations Ic and 2c with the organomodified siloxane block copolymers 1 and 2 obtained significantly better ratings, as compared to the comparison formulation V5c with the reference compound 5 according to the prior art. Particularly noteworthy is the good evaluation of the gloss properties of all formulations according to the invention.

Table 8: Results of conditioning hair from hair conditioner formulations

Also in the application of hair rinse formulations of the invention Id and 2 d with the organomodulated siloxane block copolymers 1 and 2 in the sensory assessment very good cosmetic ratings. The already very good properties of Comparative Formulation V5d with Comparative Compound 5 were further enhanced by the inventive formulations Id and 2d with organomodified siloxane block copolymers 1 and 2.

A significantly better rating is also achieved in the gloss by the use of the formulations according to the invention Id and 2d.
