    专利说明:

    The present invention relates to peels, namely cosmetic cleaners that contain an abrasive component. The surfactants contained in the peels of the invention are biosurfactants. The abrasive component, the biosurfactants and other components of the peels of the invention are based on natural renewable raw materials.
    Cleaning and care of smooth, healthy skin that is free of impurities or low impurities is usually not a problem. On the other hand, cleaning impure or oily skin or mixed skin is problematic because many active ingredients that are used to fight against impure or oily skin, have a very strong degreasing effect, and can cause sebum production still faster. The problem of impure skin can thus be further strengthened.
    A variant of a cosmetic cleanser, particularly preferred by many consumers, intended to be applied to an impure skin is called a peel. Peels can increase the microcirculation of the skin, giving the skin a radiant appearance.
    Cosmetic products used as peels, which are known in the state of the art, generally contain abrasive particles such as polyethylene powder, nut shell powder, almond kernel powder or apricot ; the abrasive components essentially have the function of removing dead skin cells, but also sebum and fatty substances on the skin by friction. For example, DE 10201319209894 A1 discloses peels in which a combination of polylactic acid particles and other known abrasive particles is used as the abrasive component. WO 2011/149689 discloses foaming body peels which contain biodegradable polylactic acid particles as abrasive component. These usual cosmetic cleaners and others, including peels, contain because of their excellent cleaning and foaming mainly anionic surfactants, optionally mixed with small amounts of co-surfactants.
    A large number of commercially available anionic surfactants soften the skin during the cleaning process and remove lipids from the outer layers of the skin, which can dry, brittle and sometimes chapped the skin, which is particularly undesirable for peels. On the other hand, anionic surfactants often can not be completely replaced by softer surfactants, for example non-ionic, as their cleaning and foaming effect is reduced.
    In addition, effective personal care products are increasingly demanded by consumers, in particular products that are made from renewable raw materials, as far as possible natural and that are biodegradable.
    Biotensioactives are surface active substances of microbial origin that can be produced from vegetable oil or sugar substrates. These substrates may consist in part of agricultural waste such as rice husks or effluents of the sugar industry so that, in this case, no raw materials of food production are lost. Biotensioactives meet the requirements of sustainability because they are made from renewable resources. They are used both for household cleaners, laundry detergents and dishwashing detergents (eg US 5,520,839, DE 19600743 A1), as well as for various cosmetic cleaners (for example, WO 2014/095367 A1, WO 2013/098066 A2). However, biosurfactants alone usually have low foamability.
    EP 2037942 B1 (WO 2007 143006 A1) discloses the use of specific biosurfactants in cosmetic cleaners, which may contain abrasive components. A concrete peel composition is not disclosed.
    There is a need for skin-friendly peels that are produced primarily or exclusively from natural, renewable and biodegradable products and yet meet the requirements for foaming, cleaning and peel care currently available.
    It has surprisingly been found that such peels which contain mainly or exclusively biotensioactives as surfactants, abrasive natural components and in addition a natural thickener can be produced.
    The present invention relates to a cosmetic cleanser which contains the following components, each based on the percentage by weight based on the total weight: (a) 0.1 to 20% by weight of at least one abrasive component insoluble in the water of natural origin, (b) 1 to 50% by weight of at least one biosurfactant and (c) 0.2 to 3% by weight of at least one thickener of natural origin. The cosmetic agent of the invention may also be called "peeling" in the following and contains as essential ingredient at least one abrasive component. By abrasive component is meant a component which is adapted to eliminate, during the use of the cosmetic agent, fats and stains on the skin by friction or abrasion.
    According to the invention, an abrasive component of natural origin is used as abrasive component. By natural origin is meant according to the invention that the abrasive component should not be produced by synthesis, but natural materials are used which are optionally crushed beforehand. Organic and mineral materials are suitable for this purpose. Examples of naturally occurring organic abrasive components are cellulose (crystalline), jojoba wax (jojoba wax beads) as well as parts of pulverized and / or milled plants, such as peach cores apricot, walnut hulls, orange pips, bitter orange seeds, grape seeds (Grape Kemel Exfoliator), Lychee (Lychee Exfoliator) stones, almond rings, cherry pits , bamboo powder, cranberry seeds (Cranberry Exfoliator) and / or lotus seeds (Lotus Exfoliator), possibly defatted fruit pulp from almonds, coconut, jojoba fruits, walnuts macadamia and other nuts, almond bran, wheat bran, oatmeal, sawdust (wood flour) and nut shell meal, in particular nut shell or flour flour corn on the cob, ginger powder, green tea powder, heap seed powder biscus, star anise powder, loofah powder which have all been pulverized and / or crushed and milled together with pulverized and / or crushed algae which are available as lithothamnium, micronised fucus, micronized spirulina, as well as the coal. Jojoba wax, cellulose, pulverized plant parts, especially pulverized fruit cores and / or pulverized algae, and combinations thereof are particularly preferred.
    Suitable mineral abrasive components include, for example, clay, talc, zeolites, rhyolite, sand, sea sand, pumice, chalk, limestone powder and / or marble powder. Sand, silicon dioxide and titanium dioxide are particularly preferred. Marine sand is especially preferred.
    The absolute particle sizes of the organic or inorganic abrasive components may preferably be in the range of 40 to 500 microns. The use of smaller particle sizes gives the cosmetic cleaners of the invention an effect which is generally poorer, because the abrasive components of particularly small particle size, especially when used on the skin at large pores, sometimes cause obstruction of the pores of the skin. Clogging of the pores of the skin can result in inflammatory reactions, which is undesirable. The use of larger particle sizes has also given the cleaners of the invention a poorer effect, since the abrasive effect of the particles is too strong and can cause minor skin irritation and injury.
    It is therefore particularly preferred to use particle sizes in the range of 40 to 400 μm, more preferably 50 to 300 μm, particularly preferably 60 to 250 μm, and most preferably 70 to 250 μm. at 200 pm.
    In the context of the present invention, the insolubility in water of the abrasive components of the compositions is important only if the cleaners of the invention comprise an aqueous or aqueous-alcoholic support in which the abrasive components must not be dissolved during the storage. In a preferred embodiment, the cleaners of the invention contain an aqueous carrier and should therefore be in the form of abrasive components insoluble in water. Other suitable and preferred natural abrasive components may contain polylactic acid particles. Polylactic acid, also known as polylactide or PLA, is a designation of biodegradable polymers (polyesters) that can be obtained primarily by ionic polymerization of lactide, which is a pooling of cycles of two lactic acid molecules .
    Ring opening polymerization occurs at temperatures between 140 and 180 ° C as well as under the action of catalytic compounds of tin (eg tin oxide). Plastics having a high molecular weight and fastness are thus produced. Lactide itself can be produced by fermentation of molasses or by fermentation of glucose using various bacteria.
    In addition, pure polylactides of high molecular weight can be produced using so-called polycondensation directly from lactic acid. In industrial production, however, solvent removal is problematic. Lactic acid (2-hydroxypropanoic acid) has an asymmetric carbon atom so that lactic acid has optically active centers in the L (+) and D (-) configuration. The ratio of monomer units L to monomer units D then determines the degree of crystallinity, the melting point and the biodegradability of the polymers.
    Suitable polylactic acids according to the invention are L-polylactic acid, D-polylactic acid and L / D-polylactic acid and mixtures thereof. Because of its excellent biodegradability, L-polylactic acid is particularly preferred. In a preferred embodiment of the present invention, the weight proportion of monomeric units of L-lactic acid in lactic acid is greater than 50% by weight, preferably greater than 80% by weight and in particular greater than at 90% by weight.
    The molecular weight of the appropriate polylactic acid according to the invention is preferably from 1,000 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 daitons.
    Suitable polylactic acid particles according to the invention can be spherical particles as well as irregular particles. It is believed that irregular shapes may enhance the abrasive effect of the polylactic acid particles. For more details on the shape and other characteristics of polylactic acid particles, reference is made to DE 102013209894 A1.
    The polylactic acid particles, which are used in the present invention, preferably have dimensions which are defined by their equivalent diameter area (ISO 9276-6: 2008 (E) section 7) also called "Equivalent Circle Diameter ECD" ( ASTM F1877-05 Section 11.3.2). The average ECD of a particle aggregate is calculated as the average ECD of each individual particle of an aggregate of particles of at least 10,000 particles, preferably more than 50,000 particles, in particular more than 100,000 particles, after excluded from the measurement of particles having an equivalent surface area diameter (ECD) of less than 10 μm.
    In a preferred embodiment of the present invention, the polylactic acid particles have average EDC values of 10 to 1000 μm, preferably 50 to 500 μm, more preferably 100 to 350 μm and more preferably 150 to 500 μm. at 250 pm.
    Regardless of the average particle size, the preferred cosmetic cleaners of the invention are those in which the polylactic acid particles have absolute particle sizes of 1 to 1000 μm, preferably 1 to 850 μm, particularly preferably preferred from 1 to 750 μm, even more preferably from 1 to 500 μm and particularly preferably from 1 to 300 μm.

Particularly preferred commercial products are Ecoscrub®20PC, Ecoscrub®50PC, Ecoscrub®100PC, Ecoblue®5025 and ECOGREEN®5025. Ecoscrub®20PC and Ecoscrub®50PC are particularly preferred.
    Particularly preferably, in the present invention, an abrasive component is a combination of polylactic acid particles having one or more inorganic or organic abrasive components of natural origin, in particular a combination of polylactic acid particles comprising sea sand or jojoba wax.
    The peel of the invention contains the abrasive component (s) in an amount of 0.1 to 20% by weight, preferably 1 to 15% by weight, more preferably 2 to 15 or 5 to 12% by weight, by weight. relative to the total weight of the peel. If several abrasive components are present, the percentages then refer to the sum of all the abrasive components contained. If polylactic acid particles are present, these are preferably contained in combination with another abrasive component; the polylactic acid particles are preferably present in an amount of 0.1 to 7% by weight, more preferably 1 to 5% by weight and the other abrasive components are preferably in an amount of 3 to 15% by weight more preferably 5 to 10% by weight.
    The cosmetic cleanser of the invention contains as another essential constituent one or more biosurfactants.
    By biotensioactives are meant substances which are formed by microorganisms and which are often also rejected from the cell. Biotensioactives are like conventional surfactants surface active substances that reduce the surface tension of liquids and thus promote the mixing of aqueous phases (hydrophilic) and hydrophobic phases (hydrophobic). Bio-based surfactants can be produced under mild production conditions that require low energy consumption. In general, they are easily biodegradable and their impact on the environment is very high. In addition, they are non-toxic and their production does not generate any toxic by-products.
