Abstract

Cosmetic cleaning compositions which comprise a) from 0.50 to 50.0% by weight of at least surfactant, b) from 0.20 to 30.00% by weight of at least one vegetable oil, c) from 0.10 to 5.00% by weight % of at least one natural thickening agent and d) 0.10 to 5.00% by weight of microfibrillated cellulose (MFC) are distinguished by excellent skin care properties (smooth skin feel, maintenance of moisture balance). In addition, they are storage stable and have a pleasant texture.

Description

The invention is in the field of cosmetics and relates to cleaning compositions which comprise, in addition to surfactants, higher amounts of vegetable care oils and a mixture of natural thickeners and microfibrillated cellulose.

Cosmetic cleansing compositions typically contain surfactants. Due to their excellent foaming properties, the primary surfactants used are mostly anionic surfactants, but in higher amounts they can have the disadvantage that they soften the skin and remove lipids from the outer skin layers. As a result, the (sensitive) skin, in particular after frequent cleaning with commercial cleaning agents, become dry, brittle and sometimes cracked, unless it is returned to lipids in the form of creams, lotions and / or care baths after or during cleansing.

Many so-called combination preparations for simultaneous cleaning and care of the skin during the shower or bath process are known from the prior art. These forms of application, however, have considerable disadvantages, because they are based mostly on higher amounts of oily conditioning agents (for example silicones) and / or to achieve greater mildness to smaller amounts of anionic surfactants to achieve a satisfactory care effect. The consequences are often unsatisfactory stability and foaming properties which in the past have mostly been improved by the addition of synthetic thickeners (acrylic acid (derivative) and / or urethane based polymers) and / or foam stabilizers.

In recent years, however, there has been an increasing demand for mild, nourishing, stable cleaning compositions containing the highest possible level of active ingredients of natural origin.

In the patent application WO 2016/071190 For example, mild cosmetic shower lotions with a high oil content have been proposed which contain a specific mixture of four surfactants as cleaning agent and xanthan gum as thickening and / or stabilizing agent. The compositions have excellent foaming and conditioning properties as well as excellent viscosity stabilities. The absence of surfactants with foam-stabilizing and / or gel networks forming tendencies - especially in combination with anionic surfactants - but led to a significant deterioration of the foam properties and destabilization of the cleaning care system. Partial waiver of foam boosters and / or synthetic conditioning agents (such as cationic polymers) from such systems was therefore not possible without degradation and / or loss of the aforementioned product properties.

In the application EP 2307100 surfactant-containing, particulate suspended solids containing cleaning compositions have been proposed which preferably contain as a stabilizing system a mixture of microfiber cellulose and a thickener in addition to a skin moisturizing agent as a care component. However, to stabilize the suspended particles, the compositions have an extremely high gelatinous consistency, which is undesirable for commercial personal cleansing compositions. In addition, the compositions also contain foam boosters (CMEA) and / or polyacrylate thickeners.

It is an object of the present invention to provide mild, skin-care, cosmetic cleansing compositions with very good foaming properties which contain high amounts of vegetable care oils and as small as possible no synthetic thickeners, conditioners and / or foam boosters. The cleaning compositions should also have excellent texture as well as very good stability and storage properties. In addition, they should leave a good, well-groomed skin feeling after their application.

It has surprisingly been found that the above objects are achieved to a great extent by the provision of cosmetic cleansing compositions in which vegetable oils have been stabilized using a mixture of microfibrillated cellulose and a natural thickening agent in a surfactant and water containing base.

wobei sich die Mengenangaben auf das Gesamtgewicht der kosmetischen Reinigungszusammensetzung beziehen.A first subject of this application is a cosmetic cleaning composition containing:

• a) from 0.50 to 50.0% by weight of at least surfactant,
• b) 0.20 to 30.00% by weight of at least one vegetable oil,
• c) 0.10 to 5.00 wt .-% of at least one natural thickener and
• d) 0.10 to 5.00% by weight of microfibrillated cellulose

wherein the amounts are based on the total weight of the cosmetic cleaning composition.

The cleaning compositions according to the invention have very good stability and care properties: they leave a non-greasy, smooth skin feel after use and, in particular, maintain the moisture balance of the skin during and after cleansing. A further advantage of the compositions according to the invention is that the combination of vegetable care oils and microfibrillated cellulose is already sufficient for achieving a very good care performance of the compositions. An addition of other care substances - especially purely synthetic care agents such as purely synthetic cationic polymers such as Polyquaternium-6 or Polyquaternium-7 - is not required. The attractive appearance and haptics of the compositions according to the invention provide a further advantage: usually a clouding agent is added to cosmetic cleansing agents in order to achieve an attractive, lotion-like appearance of the compositions. This is not necessary in the preparation of the compositions according to the invention since they already have a white, creamy appearance without the addition of any opacifiers (such as, for example, synthetic styrene-acrylate copolymers). Finally, the combination of microfibrillated cellulose and a natural thickening agent in the compositions of the invention resulted in products with a very pleasant feel. Earlier, predominantly based on natural thickening products often had a gel-like consistency, which is not desirable in cleaning-care combination preparations.

The cleaning compositions of the invention may preferably be formulated as liquid or flowable cleaning compositions such as liquid soaps, shower gels, shower creams, shower baths, shower balms and / or cream baths. In this case, they preferably contain the active ingredients a) to d) in a suitable cosmetic carrier. For the purposes of the invention, this is preferably understood to mean an aqueous carrier which (based on the total weight of the cosmetic cleaning compositions) is preferably at least 60% by weight, more preferably at least 65% by weight, particularly preferably at least 70% by weight and particularly preferably contains at least 75 wt .-% water. Furthermore, the cosmetic carrier may contain 0.01 to 30 wt .-%, preferably 0.05 to 20 wt .-% and in particular 0.1 to 10 wt .-% of at least one alcohol. Suitable alcohols are, for example, ethanol, ethyldiglycol, 1-propanol, 2-propanol, isopropanol, 1,2-propylene glycol, 1,3-propylene glycol, 1-butanol, 2-butanol, 1,2-butanediol, 1,3-butanediol, 1,4-butanediol, 1-pentanol, 2-pentanol, 1,2-pentanediol, 1,5-pentanediol, 1, hexanol, 2-hexanol, 1,2-hexanediol, 1,6-hexanediol, glycerol, polyethylene glycol, Sorbitol, sorbitan, benzyl alcohol, phenoxyethanol or mixtures of these alcohols. Preference is given to the water-soluble alcohols, such as ethanol, 1,2-propylene glycol, glycerol, sorbitol, benzyl alcohol and / or phenoxyethanol and mixtures of these alcohols. Particularly preferred are glycerol and / or sorbitol.

A fourth essential component of the cleaning compositions according to the invention is microfibrillated cellulose (MFC) d) in a weight fraction of the total weight of the cleaning compositions of from 0.01 to 5.00% by weight.

Cellulose fibers are composed of fibril bundles, which in turn consist of even smaller elements, the microfibrils. Through special fibrillation processes, a high number of hydroxyl groups are made accessible in the cellulose fibers, creating three-dimensional networks of microfibrils of an ultra-high surface, the so-called microfibrillated cellulose (MFC). The fibrillation process gives crystalline MFC which has a very high water retention capacity and is outstandingly suitable as a natural rheology modifier in cosmetic compositions.

MFC shows pseudoplastic (non-Newtonian) behavior.

An example of a particularly suitable microfibril (MFC), which can be used in the present invention is available under the trade designation Exilva ^® from Borregaard.

The proportion by weight of the microfibrillated cellulose d) in the total weight of the cleaning compositions according to the invention is from 0.01 to 5.00% by weight, preferably from 0.05 to 4.00% by weight, more preferably from 0.10 to 3.00% by weight, and in particular 0.50 to 2.00 wt .-%.

It has been found that products of particularly good stability and with very good rheology properties can be obtained if the at least one natural thickening agent c) is present in a certain weight ratio to the microfibrillated cellulose d). Particularly advantageous is a weight ratio c): d) in the range of 0.5: 1 to 1: 1.5, preferably from 0.65: 1 to 1: 1.25: 1 and in particular from 0.80: 1 exposed to 1: 1.
