Definitions
- Cosmetic consisting of a packaging material and a preparation containing 1,2-propanediol ester
- the present invention relates to a cosmetic made from a cosmetic preparation containing 1,2-propanediol ester and a packaging material made from HDPE, LDPE, PP or PET.
- Moisturizing and moisturizing of the skin are often added to them, which regenerate the skin and, for example, prevent and reduce its premature aging (e.g. the development of fine lines, wrinkles).
- Skin care products are usually packaged in bottles, tubes or
- crucibles consist mainly of glass (glass jars) or plastics such as high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP) or polyethylene terephthalate (PET).
- HDPE high-density polyethylene
- LDPE low-density polyethylene
- PP polypropylene
- PET polyethylene terephthalate
- these packaging materials In order to conserve natural resources, attempts are therefore being made to make these packaging materials as thin as possible and to recycle them after the preparation has been used.
- these thin-walled packaging materials have the disadvantage that, if the cosmetic preparation filled in them contains one or more oil components, they are not particularly stable in storage, but rather swell on contact with the oil, since the oil is "sucked up” and absorbed by the plastic.
- the products can oil out.
- the oil in the plastic means that the inscriptions printed on the packaging can smudge and become detached.
- the oil absorbed by the packaging makes it more difficult to recycle the plastic because the oil has to be separated from the polymer in a laborious process before new packaging can be made from the polymer plastic.
- oil-free preparations e.g. toothpaste
- packaging has to be coated or sealed on the inside facing the cosmetic, which is a complex process.
- protective barriers made of ethylene vinyl alcohol are known from the prior art, which are relatively expensive and also less easy to recycle than pure polyolefin packaging materials.
- a cosmetic consisting of a) a packaging material made of high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP) or polyethylene terephthalate (PET), and b) a cosmetic preparation containing 1,2-propanediol ester .
- HDPE high-density polyethylene
- LDPE low-density polyethylene
- PP polypropylene
- PET polyethylene terephthalate
- either one or more of these 1,2-propanediol esters can be used.
- these oil components of the prior art tend to be relatively strong in these packaging materials to migrate. Therefore, such products usually have a protective layer of, for example, ethylene vinyl alcohol on the inside, which is usually not or does not have to be declared on the packaging.
- the packaging means a is formed from high-density polyethylene (HDPE).
- HDPE high-density polyethylene
- the packaging a has a wall thickness (thickness) of 1 to 8 mm.
- the advantageous embodiments of the present invention according to the invention are characterized in that the packaging has no protective layer (e.g. made of ethylene vinyl alcohol) on the inside facing the preparation.
- the packaging has no protective layer (e.g. made of ethylene vinyl alcohol) on the inside facing the preparation.
- the 1,2-propanediol ester is propylene glycol dicaprate (INCI: Propylene Glycol Dicaprate), propylene glycol dicaprylate/dicaprate (INCI: Propylene Glycol Dicaprylate/Dicaprate), propylene glycol diheptanoate (INCI: Propylene Glycol Diheptanoate), propylene glycol dibenzoate (INCI: Propylene Glycol Dibenzoate ) and/or dipropylene glycol dibenzoate (INCI: Propylene Glycol Dibenzoate) is used.
- Embodiments of the present invention that are advantageous according to the invention are also obtained in that the preparation is free from dimethicone (INCI: Dimethicone).
- the preparation is free from silicone oil, mineral oil, paraffin wax, microcrystalline wax, shellac wax and polyethylene wax.
- the preparation is free from polyacrylates, crosslinked acrylate/C10-C30 alkyl acrylate polymers and vinylpyrrolidone/hexadecene copolymers and free from 3-(4-methylbenzylidene)camphor, 2-hydroxy-4-methoxybenzophenone (INCI: oxybenzone), 2-ethylhexyl 4-methoxycinnamate (INCI octyl methoxycinnamate), ethylhexyl 2-cyano-3,3-diphenyl acrylate (INCI: octocrylene), parabens (particularly methyl, propyl and butyl paraben), methylisothiazolinone, chloromethylisothiazolinone and DMDM hydantoin, polyethylene glycol ethers or polyethylene glycol esters
- the cosmetic preparation is in the form of an emulsion. It is preferred according to the invention if the cosmetic preparation is in the form of an oil-in-water emulsion (O/W emulsion). It is advantageous according to the invention if the cosmetic preparation contains 1,2-propanediol ester in a concentration of 1.0 to 15% by weight, based on the total weight of the preparation. A use concentration of 1 to 5% by weight, based on the total weight of the preparation, is preferred according to the invention. These use concentrations relate to the total amount of 1,2-propanediol esters used. If only a 1,2-propanediol ester (e.g.
- propylene glycol dicaprate (INCI: Propylene Glycol Dicaprate), propylene glycol dicaprylate/dicaprate (INCI: Propylene Glycol Dicaprylate/Dicaprate), propylene glycol diheptanoate (INCI: Propylene Glycol Diheptanoate), propylene glycol dibenzoate (INCI: Propylene Glycol Dibenzoate), Dipropylene glycol dibenzoate (INCI: Propylene Glycol Dibenzoate)) used, this is the advantageous or preferred use concentration for this one compound.
- the total amount of 1,2-propanediol esters in the oil phase of the preparation is at least 3% by weight, based on the total weight of the oil phase.
- the preparation contains one or more oils selected from the group consisting of the compounds octyldodecanol, caprylic/capric acid triglycerides (INCI: caprylic/capric triglycerides), coconut glycerides (INCI: cocoglycerides), tridecyl stearate (INCI: tridecyl stearate) , tridecyl trimelliate (INCI: Tridecyl Trimelliate).
- the preparation contains one or more oils selected from the group of compounds containing polycitronellol (INCI: polycitronellol), polycitronellol acetate (INCI: polycitronellol acetate), triolein, ethylhexylacetoxystearate (INCI: ethylhexyl acetoxystearate) and/or acetylethylhexylpolyhydroxystearate ( INCI: Acetyl Ethylhexyl Polyhydroxystearate).
- oils selected from the group of compounds containing polycitronellol (INCI: polycitronellol), polycitronellol acetate (INCI: polycitronellol acetate), triolein, ethylhexylacetoxystearate (INCI: ethylhexyl acetoxystearate) and/or acetylethylhexylpolyhydroxystearate ( INCI: Acet
- the preparation contains one or more oils selected from the group consisting of almond oil (INCI: Prunus Amygdalus Dulcis Oil) and/or sunflower oil (INCI: Helianthus Annuus Seed Oil), hydrogenated castor oil (INCI: Hydrogenated Castor Oil) contains.
- almond oil INCI: Prunus Amygdalus Dulcis Oil
- sunflower oil INCI: Helianthus Annuus Seed Oil
- hydrogenated castor oil INCI: Hydrogenated Castor Oil
- the preparation contains tocopherol and/or tocopherol acetate.
- the preparation contains ethanol and/or ethylhexylglycerol.
- the preparation according to the invention can contain the ingredients customary for cosmetics and be composed accordingly. comparison attempts
- the penetration of the following cosmetic oils into the packaging material HDPE was examined.
- the product “Hostalen ACP 5831 D” from Lyondellbasell was used as the HDPE.
- Weight increase (%) (m1 - mO) / mO
- the formula (m1 - m0)/m0 is used to determine the weight increase (%) of the raw material or cosmetic preparation that has migrated into the packaging material.
- the mean value [%] and standard deviation [%] of the triple determination are also calculated.
