Description

"Cosmetic face and body peeling"

The invention is in the field of cosmetics and relates to detergents which contain a special mixture of two abrasive components.

Washing, cleansing and caring for the human body is an important basic need, and cosmetic manufacturers are always trying to meet the ever-changing and evolving needs of consumers by providing novel and / or improved products.

A fundamental part of daily hygiene, for example, is the thorough cleansing of the skin, optimally while improving the appearance of the skin.

Cleaning and maintaining healthy, smooth skin with little or no blemishes usually causes no problems.

The cleaning of impure or oily skin or the combination skin, however, is problematic, as many

Active ingredients that are used to combat blemished or oily skin, have a very strong degreasing effect, and can provoke even faster sebum production. The problem of impure skin can be further aggravated.

Just as probiematic is the cleaning and care of large-pored skin, which is considered particularly in the face, on the neck and Dekoileteebereich and on the upper back as unpleasant and disturbing. In the prior art astringent agents for the refinement of skin pores are known. These pull the skin together on the surface and thus create the impression of a small-pored skin in a short time. At the same time, however, these agents deprive the skin of the moisture that is urgently needed to maintain a firm and wrinkle-poor skin.

There is therefore a need for cosmetic agents which are particularly suitable for the cleaning of large-pored, impure skin or the combination skin.

One of many consumers particularly preferred variant of cosmetic cleanser for use on blemished skin are so-called peels.

Cosmetic peeling products known in the art often contain abrasive particles such as polyethylene powder, walnut shell powder, apricot or almond kernel powder. These powders can cause skin irritation when used, as they do not change on skin treatment itself and often remain at least partially on the skin. Because of this irritant effect appropriate exfoliating formulations can not be used daily as a rule, but it must remain periods without application, in which the skin can regenerate. Moreover, it is often necessary, after the application of such products, to apply skin care creams to the treated skin in order to nourish and moisturize the skin attacked by the treatment.

Therefore, there is still a demand for improved peeling products which avoid the disadvantages of the known products.

WO 2011/149689 describes foaming body scrubs which contain biodegradable lactic acid particles as an abrasive component. The application states that the peels are more environmentally friendly with the same effectiveness than known body scrubs containing synthetic polymer particles.

Although the body scrubs described in the application are in principle suitable for removing sebum and dead skin cells, they can not adequately cover all consumer needs.

There is therefore still a need for skin-friendly peels, which are particularly suitable for the cleaning of large-pored skin and / or impure combination skin.

The object of the present invention was to provide mild, cosmetic peels which remove excess fat, sebum and dead skin cells without excessively drying and / or irritating the skin during and after cleansing. Another object of the invention has been to provide cosmetic peels which eliminate, reduce or refine blemishes and / or large pores of the skin and improve the overall appearance of the skin.

It has been found that the said tasks can be fulfilled by the combination of certain abrasive active ingredients in a cosmetic cleaning agent.

A first subject of the present application is therefore a cosmetic cleaning agent, the a) polylactic acid particles and

b) contains at least one further, different from a), organic or inorganic, water-insoluble abrasive component having absolute particle sizes in the range of 40 to 500 m.

The cosmetic cleansing compositions according to the invention preferably contain 0.5 to 20 wt .-%, more preferably 1 to 15 wt .-% and particularly preferably 1 to 8 wt .-% polymic acid particles! and

From 1 to 20% by weight, more preferably from 5 to 15% by weight and particularly preferably from 7 to 10% by weight of at least one further, organic or inorganic, water-insoluble abrasive component other than a),

wherein the quantities are based on the total weight of the cosmetic cleaning agent.

As a first essential ingredient, the detergents according to the invention contain polylactic acid particles.

Polylactic acid, also called polylactide or PLA, is a term for biodegradable polymers (polyesters), which are mainly accessible by the ionic polymerization of lactide, an annular combination of two lactic acid molecules.

At temperatures between 140 and 180 ° C. and the action of catalytic tin compounds (eg tin oxide), a ring-opening polymerization takes place. This produces plastics with a high molecular weight and strength. Lactide itself can be made by fermenting molasses or by fermenting glucose with the help of various bacteria.

In addition, high molecular weight and pure polylactides can be produced directly from lactic acid by means of the so-called polycondensation. In industrial production, however, the disposal of the solvent is problematic.

The lactic acid (2-hydroxypropanoic acid) has an asymmetric carbon atom, so that the polylactic acid also has optically active centers in L (+) and D (-) configuration. The ratio of L to D monomer units determines the degree of crystallinity, the melting point and the biodegradability of the polymers.

Polylactic acids suitable according to the invention are L-polylactic acid, D-polylactic acid and L / D-polylactic acid and mixtures thereof. Because of its very good biodegradability, L-polylactic acid is particularly preferred. In a preferred embodiment of the present invention, the weight fraction of L-lactic acid monomer units in the polylactic acid is greater than 50% by weight, preferably greater than 80% by weight and in particular greater than 90% by weight.

The molar mass of the polylactic acid suitable according to the invention is preferably from 1000 to 1,000,000, preferably from 10,000 to 300,000, more preferably from 50,000 to 250,000 and in particular from 100,000 to 180,000 daltons. In a further preferred embodiment of the present invention, the polylactic acid is used in a form veneered with fillers. The use of larger amounts of filler helps to comminute the polymer into particles, increases biodegradability and internal specific surface area through porosity and capillarity. In particular, water-soluble fillers are preferred here, for example metal chlorides such as NaCl, KCl, etc, metal carbonates such as Na 2 CO 3, NaHCO b, etc., metal sulfates such as MgSO 4.

As fillers and natural raw materials can be used, for example, nut shells, wood or bamboo fibers, starch, xanthan gum, alginates, dextran, agar, etc. These fillers are biodegradable and do not degrade the good ecological properties of polylactic acid particles. Usually, the content of biodegradable fillers in the polylactic acid particles can be from 10 to 70% by weight, with amounts of from 20 to 60 being preferred, and those of from 30 to 50% by weight being particularly preferred.

Polylactic acid particles which are suitable according to the invention can be present both in spherical form and as irregular particles which have a certain circularity.

It is believed that irregular shapes can enhance the abrasive action of the polylactic acid particles, therefore, for some embodiments of the present invention, it may be advantageous for the polylactic acid particles to preferably have a circularity between 0.1 and 0.6.

On the other hand, polylactic acid particles of lower circularity may be preferred if a less abrasive, gentler abrasive action of the cleaning agent according to the invention is to be achieved.

The shape of the polylactic acid particles used according to the invention can be defined in various ways, in the context of this preferred embodiment of the present invention, the geometric proportions of a particle and - pragmatic - a particle population are determined.

Highly accurate newer methods allow the accurate determination of particle shapes from a large number of particles, usually more than 10,000 particles, preferably more than 100,000 particles. These methods allow accurate selection of the average particle shape of a particle population. The determination of the particle shapes is preferably carried out with an "Occhio Nano 500 Particle Characterization Instrument" using the software "Callistro version 25" (Occhio sa Liege, Belgium) .This instrument enables the preparation, dispersion, imaging and analysis of a particle population, preferably the instrument parameters be set as follows: White Requested = 180, vacuum time = 5000ms, sedimentation time = 5000ms, automatic threshold, number of particles counted / analyzes = 8000 to 500000, minimum number of replicates / sample = 3, lens setting lx / 1 .5x.

The polylactic acid particles which are used according to the invention preferably have sizes which, by their area equivalent diameter (ISO 9276-6: 2008 (E) section 7), are also called "Equivalent Circle Diameter ECD" (ASTM F1877-05 Section 1 1. The mean ECD of a particle population is calculated as the average ECD of each individual particle of a particle population of at least 10,000 particles, preferably more than 50,000 particles, more preferably more than 100,000 particles, after having particles of area equivalent diameter (ECD) below of 10 [im were excluded from the measurement.

In a preferred embodiment of the present invention, the polylactic acid particles have average ECD values of from 10 to 1000 [im, preferably from 50 to 500 [im, more preferably from 100 to 350 [im and in particular from 150 to 250 [im.

Regardless of the average particle size, cosmetic cleansing compositions according to the invention are preferred in which the polylactic acid particles have absolute particle sizes of from 1 to 1000 μm, more preferably from 1 to 850 μm, particularly preferably from 1 to 750 μm, very preferably from 1 to 500 μm [im and particularly preferably from 1 to 300 [im have.

In the context of the present invention, form descriptors are used, which are calculations from geometric descriptors or form factors. Form factors are relationships between two different geometric properties, which in turn

measuring the proportions of the image of an entire particle or measuring the proportions of an ideal geometric body enclosing the particle.

These results are descriptors that are similar to aspect ratios. In a preferred embodiment of the present invention, meso-form descriptors are used for particle characterization. These meso shape descriptors indicate to what extent a particle deviates from an ideal geometric shape, in particular from a sphere.

In a first preferred embodiment of the present invention, the polylactic acid particles can deviate from the typical spherical shape or sphere-like shapes such as granule particles (see above).

In this case, the particles preferably have sharp corners and edges and preferably have concave indentations. Sharp corners of non-spherical particles can be defined by a radius be defined below 20 μητι, preferably below 8 μιτι and in particular below 5 μιτι, wherein the radius is defined as the radius of an imaginary circle that follows the contour of the corner.

Circularity is a quantitative 2-dimensional image analysis and can be determined according to ISO 9276-6: 2008 (E) section 8.2. Circularity is a preferred meso-form descriptor and may be determined, for example, with the "Occhio Nano 500 Particle Characterization Instrument" described above using the "Callistro version 25" software (Occhio, supra, Liege, Belgium) or "Malvern Morphologi G3". Circularity is sometimes described in the literature as the difference between a particle and the perfect sphere. The values for circularity vary between 0 and 1, where 1 describes the perfect sphere or (in the two-dimensional image) the perfect circle:

C = [(4πΑ (/ ρ ² ] ^{, / ζ} where A is the projection area (the two-dimensional descriptor) and p is the length of the perimeter of the particle.

Within this preferred embodiment, polylactic acid particles having an average circularity C of from 0.1 to 0.6, preferably from 0.15 to 0.4, and in particular from 0.2 to 0.35, have been described in the context of the present invention proved particularly suitable. Here, the mean values are obtained by quotient formation from volume-based measurements and number-based measurements.

Solidity is a quantitative 2-dimensional image analysis and can be determined according to ISO 9276-6: 2008 (E) section 8.2. Solidity is also a preferred meso-form descriptor and can be determined, for example, with the "Occhio Nano 500 Particle Characterization Instrument" described above using the "Callistro version 25" software (Occhio, supra, Liege, Belgium) or "Malvern Morphologi G3". Solidity is a meso-form descriptor that describes the concavity of a particle or particle aggregate. The values for solidity vary between 0 and 1, where 1 describes a non-concave particle:

Solidity = A / Ac where A is the (image) area of the particle and Ac is the area of the convex hull enclosing the particle.

Within the first preferred embodiment, polylactic acid particles having an average solidity of from 0.4 to 0.9, preferably from 0.5 to 0.8 and in particular from 0.55 to 0.65 im Framework of the present invention proved to be particularly suitable. Here, the mean values are obtained by quotient formation from volume-based measurements and number-based measurements.

Particularly preferred polylactic acid particles of the first preferred embodiment preferably have an average circularity C of from 0.1 to 0.6, preferably from 0.15 to 0.4 and in particular from 0.2 to 0.35 and an average solidity of 0, 4 to 0.9, preferably from 0.5 to 0.8 and in particular from 0.55 to 0.65.

The "mean" circularities and solidities are averages from the measurement of a large number of particles, usually more than 10,000 particles, preferably more than 50,000 particles, and especially more than 100,000 particles, with particles of area equivalent diameter (ECD) below 10 μητι were excluded from the measurement.

After its preparation, the polylactic acid polymer can be converted to the desired particle size and shape, for example by milling, depending on which mold is needed for which purpose.

A particularly preferred process for preparing polylactic acid particles of desired circularity and solidity is to produce a foam of polylactic acid and subsequent grinding.

It is believed that a certain hardness may enhance the abrasive action of the polylactic acid particles, therefore, for some embodiments of the present invention, it may further be advantageous for the polylactic acid particles to cure from 3 to 50 kg / mm ² , preferably from 4 to 25 kg / mm ² and especially from 5 to 15 kg / mm ² on the HV Vickers hardness scale.

The hardness of the particles can be varied by the ratio of D to L monomers and the molecular weight.

Polylactic acid particles that can be used with preference in the inventive cleaning compositions are commercially available (for example, by the company Micro Powders, Inc. under the trade names Ecosrub ^®). Particularly preferred are the commercial products Ecosrub ^® 20PC, 50PC Ecosrub ^®, Ecosrub ^® 100PC, Ecoblue ^® 5025 and Ecogreen ^® 5025. Particularly preferred Ecosrub ^® 20PC and Ecosrub ^® 50PC are. As a second essential ingredient, the cleaning agents according to the invention contain at least one further, different from a), organic or inorganic, water-insoluble abrasive component having absolute particle sizes in the range of 40 to 500 μιη.

The use of abrasive components b) of smaller particle sizes leads to an overall poorer effect of the cosmetic cleansing compositions according to the invention, since abrasive components b) of a particularly small particle size - in particular when used on large-pored skin - sometimes led to clogging of the skin pores. Clogging of the skin pores can result in inflammatory reactions, which is undesirable.

The use of abrasive components b) of larger particle sizes also led to a detrimental effect of the inventive detergent, since the abrasive action of the particles was too strong and led to irritation and minor damage to the skin.

Particularly preferred abrasive components b) therefore have particle sizes in the range from 40 to 400 μm, more preferably from 50 to 300 μm, particularly preferably from 60 to 250 and very preferably from 70 to 200 μm.

In the context of the present invention, the water insolubility of the abrasive components b) is important if the cleaning agents according to the invention have an aqueous or aqueous-aoic carrier in which the abrasive components are not to be dissolved during storage; in a preferred embodiment, the inventive detergents have one aqueous or aqueous Aikohoiischen carrier, therefore, water-insoluble components are required as Abrasivkomponenten b).

Particularly suitable abrasive components b) can be selected from organic or inorganic substances.

Suitable organic substances are, for example, polymer particles, in particular polyethylene and / or polyamide-1 1 particles, crystalline cellulose, hardened jojoba oil! (Jojoba-beads) as well as crushed and / or ground plant parts, such as crushed and / or ground peach, apricot, wainuss, almonds and / or cherry kernels, if necessary, defatted flesh of almonds, coconuts, jojoba fruits, acadamia nuts and other nuts, almond bran, wheat bran, oatmeal, sawdust (wood flour) and nut shavings flour, in particular walnut shell mehi or corn cob meal.

Suitable inorganic substances are, for example, clay, sea sand, glass dust, pumice, chalk, shell limestone and / or marble flour. Particularly preferred cosmetic cleansing compositions according to the invention are characterized in that they contain an inorganic, water-insoluble abrasive component b), which may preferably be selected from alumina, sea sand, glass dust, pumice, chalk, Muscheikaikmehi and / or marble flour. Sea sand is extremely preferred.

In a second particularly preferred embodiment, inventive cosmetic cleaning agents therefore contain

a) Polymiichsäure particles of an absolute Teslchengröße in the range of 1 to 850 μηπ, preferably from 1 to 750 μηι, more preferably from 1 to 500 μιη and most preferably from 1 to 300 m, and

b) Seesand particles of an absolute particle size in the range from 40 to 400 μm, preferably from 50 to 300 μm, more preferably from 60 to 250 μm and most preferably from 70 to 200 μm.

In addition to the abrasive properties of the inventive cleaning agents should continue to be mild to the skin and have a good cleaning and care effect.

Due to their excellent cleaning and foaming power, conventional cosmetic cleaners contain predominantly anionic surfactants, optionally in the mixture with small amounts of co-surfactants.

A variety of commercially available anionic surfactants soften the skin during the cleaning process and remove lipids from the outer skin layers. As a result, the skin may become dry, brittle and sometimes cracked, which is undesirable, especially with peels. On the other hand, anionic surfactants often can not be completely replaced with milder - for example, nonionic - surfactants because it reduces the cleaning and foaming action of the compositions.

It has been found that particularly mild detergents according to the invention can be prepared if the abrasive components a) and b) are incorporated in a suitable carrier which contains not more than 15% by weight of at least one mild anionic, amphoteric / zwitterionic and / or zwitterionic surfactant.

In a further preferred embodiment, the cosmetic Reinigungsmättei invention therefore contain 0.5 to 15 wt .-%, more preferably 1 to 13 wt .-% and particularly preferably 2 to 12 wt .-% of at least one anionic, amphoteric / zwitterionic and / or nonionic surfactant, preferably at least one amphoteric surfactant. The quantities are based on the total weight of the cosmetic cleaning agent. A suitable cosmetic carrier is preferably understood as meaning an aqueous or aqueous-alcoholic carrier.

The support preferably contains at least 50% by weight, more preferably at least 55% by weight and particularly preferably at least 60% by weight of water.
