Description

Cosmetic composition containing hydrophobic flakes Technical field
The present invention belongs to the cosmetic field， and specifically relates to a cosmetic composition， a transparent packaging containing the cosmetic composition， hydrophobic flakes and use of alcohol (s) in production of the hydrophobic flakes.
Technical background
A beautiful and attractive appearance is a desire for many people. Therefore， an essential part of the daily personal care of humans is focused on their skin. For that purpose， cosmetic compositions in form of creams， lotions and/or oils are topically applied to the human skin. Within cosmetic compositions active ingredients are contained to reduce wrinkles， moisturize the skin， protect the skin from UV-radiation or generally to improve the appearance of the skin.
The problem of active ingredients not being soluble in water is often addressed by diluting the insoluble components in a lipophilic phase which can be suspended in an aqueous outer phase. Such compositions are often referred to as oil-in-water (O/W) -emulsions. However， those systems often have the disadvantage that the suspended lipophilic droplets are mostly very small and often not visible for the customer. Therefore， for some consumers the appearance of O/W-emulsions is rather boring.
Even though the suspended lipophilic droplets are visible by eye to the customer， these droplets have a round and/or micellar shape. This is most likely due to the use of surfactants which promote the formation of the oil droplets in an aqueous phase. However， in order to provide the  customers with sensory attractive cosmetic compositions， it is desirable to form hydrophobic flakes with a unique and irregular shape suspended in an outer aqueous phase. Thereby， active ingredients should be contained in the hydrophobic flakes. Preferably， the hydrophobic flakes melt and/or are spread upon application on human skin such that the active ingredients may be released.
It is also desirable to provide an improved cosmetic composition with hydrophobic flakes， wherein the flakes feel soft and smooth when applied to the skin.
WO 2012177757 A2 describes a personal care composition comprising irregular shaped particles. These particles can be made from a range of organic and inorganic materials， such as silica， carbonate-derived salts and polymeric compounds. The described particles are solid and do not melt or/and are spread upon application.
WO 2006048115 A1 discloses aqueous liquid cleansing compositions comprising gel flakes formed from hydrophilic polysaccharides， such as gellan gum， xanthan gum， pectin， gum arabic and other polysaccharides.
US 6117419 A discloses a method of preparing hydrophobic flakes which may contain active ingredients. The flakes are formed by pumping a liquid phase of waxy material onto a surface of a stirred hydrophilic gel， wherein the hydrophobic gel is an aqueous solution containing substances such as cellulose gums， cellulose gum esters， alginate gums， acrylic acid polymers， poly vinyl methyl ether/maleic anhydride decadiene crosspolymer， carbomer or hyaluronic acid.
However， following the described production method disclosed in US  6117419 A the hydrophobic flakes formed vary significantly in size. This variance is a disadvantage for cosmetic companies who try to produce cosmetic products with comparable appearance within a single product as well as across a whole product range.
Summary of Invention
The present invention is to provide a cosmetic composition comprising hydrophobic flakes with improved properties. In particular， it was the objective of the present invention to provide a cosmetic composition with hydrophobic flakes， wherein the variance of the size of the hydrophobic flakes is reduced in comparison to the hydrophobic flakes known from prior art. It was another objective of the present invention to provide a method of producing hydrophobic flakes with reduced variance in size. These objectives were surprisingly solved by the present invention.

All percentages and ratios used herein are by weight of the total composition， unless otherwise designated.
All measurements are understood to be made under ambient conditions， which means at a temperature of 25℃ ， at an atmospheric pressure of 1013 hPa and at 50％relative humidity， unless otherwise designated.
The term “flake” refers to a solid or semisolid material， which is homogeneous and which is suspended in an aqueous phase.
The term “hydrophobic flake” means a flake which contains water insoluble hydrophobic molecules and the hydrophobic part of amphiphilic molecules.
In the case the hydrophobic flake contains the hydrophobic part of amphiphilic molecules the formed layer of the amphiphilic molecules is not considered as wall of a capsule.

The term “hydrophobic flake” does also explicitly not refer to a capsule. Capsules are substances with a wall and a core， wherein the core comprises fragrances or active ingredients. Hence， capsules are not homogeneous.
The term “the hydrophobic flake contains/comprises” means that either a molecule is fully contained or at least partly contained in the hydrophobic flake.
The term “transparent packaging” refers to a packaging which allows at least one wavelength in the range from 390 nm to 700 nm to be transmitted through the packaging by 5％of the incident light.
The term “free from” means that the concentration of the substance is less than 0.1％by weight of the total composition.
The term “variance in size” or “variance of the size” means the variance determined for the particle length analyzing a population of at  least 200 hydrophobic flakes， wherein the particle length of the hydrophobic flakes analyzed is in the range from 0.01 mm to 50 mm， preferably from 0.1 mm to 50 mm.
The term “particle length” refers to the distance between the most apart edges of each particle. This distance can easily be determined using a microscope and/or a photography of the hydrophobic flakes in the cosmetic composition.
The term “fatty alcohols” refers solely to primary alcohols containing 12 to 36 carbon atoms.
The term “fatty acids” refers to a carboxylic acid with a saturated or unsaturated hydrocarbon chain containing 8 to 36 carbon atoms.
The term “synthetic or chemically modified waxy material” refers explicitly not to natural waxes such as beewax， carnabau wax， lanolin， shellac wax， castor wax， ouricury wax， rice bran wax soy wax， candelilla wax， bayberry wax or other naturally occurring waxes.
