The present invention also relates to methods of producing said product.
Further aspects of the present invention will arise from the description below, in particular from the examples, as well as from the attached patent claims.
It is a well-known problem that certain substances, in particular fragrance and/or flavouring substances and perfume oils contained in fragrance and/or flavouring compositions interact with the plastic packaging they are contained in for transport, handling and/or storage. Depending on the type of substances and their concentration, they diffuse into or through the plastic and disadvantageously may cause problems such as
It was further found that the damage to the plastic containers described above may be worsened by or occur more often in the presence of surface-active compounds such as tensides, solubilisers and emulsifying agents. This leads to the loss of valuable fragrance and/or flavouring substances from fragrance and/or flavouring substance compositions leading to an altered olfactory impression of the product over time. Moreover, labels on the plastic packaging may become illegible, which is particularly disadvantageous in the case of warning labels. Lastly, products comprising discoloured or deformed packaging are difficult to sell to customers leading to loss of value of the products and to customer complaints.
Plastic containers as mentioned above may, for example, be made from polyethylene (PE), polypropylene (PP) and polyethylene terephthalate (PET) or mixtures thereof. In particular with respect to these materials, there is an ongoing need for products comprising or consisting of plastics used for packaging purposes such as polyethylene (PE), polypropylene (PP) and polyethylene terephthalate (PET) and, in particular, fragrance and/or flavouring substances contained therein, whereby the composition of the fragrance and/or flavouring substances or comprising the same is such that the plastic packaging is neither altered nor damaged during the whole life cycle of the product. Preferably, the composition is such that one or more of the above described detrimental effects, preferably all of these effects, are avoided or at least reduced.
One prior art approach to solve the problem described above has been the use of combination systems of different types of plastics as containers such as, for example, intermediate bulk containers (IBC) made of PE/ethylene vinyl alcohol (EVOH). EVOH, however, despite its advantageous properties, is difficult to synthesise and thus containers comprising this type of plastic are more expensive to produce.
Therefore, the object of the present invention was to provide compositions that are compatible for storage in low cost standard plastic containers such as the ones made from PE and/or PP and/or PET.
Further objects underlying the present invention follow from the description below and the present patent claims.
According to a first aspect of the present invention, the stated object is achieved by a product comprising or consisting of
In the context of the own studies underlying the present invention, it was surprisingly found that if the compounds contained in composition (ii) are categorized as defined above and if the total amounts of compound(s) of group (A) and of group (B), if present, and of group (C) are restricted to the amounts in the composition as defined above, a particularly stable product may be obtained, wherein composition (ii) as defined above does not interact with the plastic of container (i) as defined above to a significant extent. In other words, one or more of the detrimental effects mentioned above can be avoided or at least reduced.
Furthermore, due to less interactions with the plastic of the container, especially less deformation, it is possible to reduce the wall thickness of the container and to reduce the amount of packaging material.
The water solubility of the compounds is preferably calculated via the molecular structure by the program “EpiWin” of Howard+Meylan. This calculated value describes the water solubility of a compound in mg/L at room temperature. The higher the value, the more of the compound is soluble in water.
In the context of the present invention a container (i) comprising or consisting of PE and/or PP and/or PET, preferably being made from PE and/or PP and/or PET, is meant to be for example a container that either comprises or consists of a single type of plastic selected from the group consisting of PE, PP and PET, or comprises or consists of layers or blends of two or three types of different plastics selected from the group consisting of PE, PP and PET.
Moreover, the term “polyethylene (PE)”, in the context of the present invention, includes all of the different forms of PE classified by their differing density and branching, such as ultra-high-molecular-weight polyethylene (UHMWPE), ultra-low-molecular-weight polyethylene (ULMWPE or PE-WAX), high-molecular-weight polyethylene (HMWPE), high-density polyethylene (HDPE or PEAD), high-density cross-linked polyethylene (HDXLPE), cross-linked polyethylene (PEX or XLPE), medium-density polyethylene (MDPE), linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), very-low-density polyethylene (VLDPE), chlorinated polyethylene (CPE), etc, preferably HDPE or LDPE.
The term “polypropylene (PP)”, in the context of the present invention, also includes all of the different possible types of PP such as isotactic PP, syndiotactic PP, atactic PP, high crystalline PP (HcPP), random copolymers (RACO) of PP, block copolymers (HECO) of PP, uniaxially or biaxially oriented PP (BOPP), etc.
The term “polyethylene terephthalate (PET)”, in the context of the present invention, includes the different types of PET, such as polyethylenterephthalate and polyethylenterephthalate glycol.

For the determination of the category and the behavior of the compounds, the influence of each compounds on the tree different plastic types LD-PE, PP and PET-G were investigated.
Plastic Items:
Each plastic item of 13 mm×43 mm×2 mm was weighted and stored for 4 weeks at 40° C. in a 10 mL glass jar filled with a 10% solution of the single test compound in DPG. After the storage, the plastic item was taken out of the jar and carefully rinsed by dipping in ethanol. The rinsed plastic item was dabbed gently with a paper towel and immediately weighted. The weight of the plastic item before the storage and after the storage was compared and the percentage weight increase or decrease determined.
Furthermore the appearance of the plastic item was evaluated. The different evaluation qualities of the plastic items were classified as follows:
Category A compounds showed a weight increase of 5 wt. % and more, and/or colour changes after 4 weeks at 40° C.
Category B compounds showed a weight increase in a range of from 2 wt. % to less than 5 wt. % and/or other changes of the appearance, like texture changes, form changes and opaque.
Category C compounds showed a weight increase of less than 2 wt. % and no changes of the appearance.
Table 1 below shows the results of several compounds and their assigned categories A and B, while the results of several compounds of category C are shown in table 2 below:
Heat water to about 35° C. Sprinkle kelzan onto water while stirring and maintain agitation for another 30 min. to complete hydration. Add and dissolve the remaining components in the given order. Use of either blade or propeller mixer should yield good results.
The production takes place in a Becomix.
For production of phase A, the glycerin and Surfhope® C1216 are put into the Becomix and are stirred at −0.5 bar with 0.3 m/s, then they are homogenized with the aid of a Turrax at 3 m/s for 4 minutes. When the Surf Hope® C1216 is completely dissolved, the Surf Hope® C1616 is added, whereby the stirring is continued at 0.3 m/s. The subsequent homogenization takes place at 3 m/s for 4 minutes with the aid of a Turrax. Then water is added and again homogenized with the aid of a Turrax at 3 m/s for 6 minutes. This mixture is heated to 80° C. under stirring at 0.3 m/s, then brought to 50° C. and again homogenized with the aid of a Turrax with 3 m/s for 2 minutes. Subsequently, the temperature is raised to 80° C. and a pressure of −0.6 bar is adjusted.
The production of phase B takes place at 80° C. At a temperature of 80° C., the components of phase B are very slowly and consecutively mixed with each other and then stirred at 0.5 m/s as well as homogenized with the aid of a Turrax at 3 m/s for 2 minutes. When one quarter of the oil has been put into the boiler, a homogenization step takes place with the aid of a Turrax at 5 m/s for 4 minutes. After half of the oil has been added, it is homogenized again with the aid of a Turrax at 5 m/s for 4 minutes and the stirring speed is raised to 0.8 m/s. When three quarters of the oil have been added, a homogenization step with the aid of a Turrax at 5 m/s for 4 minutes and an increase of the stirring speed to 1 m/s follow. Then the remaining amount of the oil is added and stirred at 1.2 m/s.
After addition of phase C, the pressure is raised to −0.8 bar and it is homogenized with the aid of a Turrax at 5 m/s for 4 minutes. The preparation is cooled under stirring at 0.5 m/s to 25° C., whereby the stirring speed is reduced. Then phase D is added at 40° C.
