Description

  The present invention relates to a kit for preparing a non-uniform composition comprising a first and a second composition, wherein the first composition comprises at least one hydroxyalkyl modified starch. The invention also relates to a method for preparing the non-uniform composition comprising the first and the second composition.

  The DIY (Do It Yourself) trend has become a boom in the beauty industry and many products have been launched in the past few years. On the other hand, many consumers are looking for healthy, clean and safe cosmetics. Therefore, the trend of so-called "natural cosmetics" brings many possibilities at the intersection of DIY and healthy, clean and safe cosmetics. The self-made cosmetic preparations give consumers greater confidence in the health benefits, cleanliness and safety of the cosmetics.

  There is a need for consumers to prepare cosmetics that appear to be edible. For example, some consumers, like smoothies, want to prepare their own cosmetics with a non-uniform, non-uniform or non-homogenous appearance. The smoothie-like appearance can be explained by the presence of air bubbles, particles, small aggregates, or any combination thereof. The smoothie-like appearance can further strengthen the concept of healthy, clean and safe cosmetics, because smoothies have various benefits such as detoxification, hydration, increased energy and so on in general culture It is because it is known that it is a health drink.

  One skilled in the art can prepare a kit according to the present invention based on conventional packaging techniques. The kit according to the invention comprises at least a first and a second container, each container separately comprising a first and a second composition.

  The first and second containers may have outlets for dispensing or evacuating the first and second compositions from the first and second containers.

  The kit may comprise dispensing or drainage means, such as a pump, capable of removing the first and second compositions from the first and second containers, respectively.

  Optionally, the first container and / or the second container may comprise at least one propellant. The propellant can apply pressure from the first and / or second container to the first and / or second composition to facilitate dispensing or discharging the first and / or second composition. be able to.

  The propellant may be a liquefied gas, such as dimethyl ether (DME); volatile carbonizations such as n-butane, propane, isobutane, and mixtures thereof, optionally with at least one chlorinated and / or fluorinated hydrocarbon. Hydrogen, for example the compound sold under the trade names Freon® and Dymel® by Dupont de Nemours, in particular the monofluorocarbon sold by DUPONT under the trade name DYMEL 152A, in particular It may be selected from trichloromethane, difluorodichloromethane, tetrafluorodichloroethane, and 1,1-difluoroethane. The propellant may be a compressed gas such as carbon dioxide, nitrous oxide, nitrogen and / or air.

For example, the first or second composition may be contained in a flexible bag located in the first or second container, while the propellant may be contained in the flexible bag and the first or second container May be included between

  The nonuniform composition is prepared by mixing the first composition and the second composition dispensed or discharged from the first and second containers.

  The mixing ratio between the first composition and the second composition is not limited. For example, the mass ratio of the first composition to the second composition mixed can vary from 0.1: 99.9 to 99.9: 0.1. The weight ratio of the first composition to the second composition: the second composition is 1:99 to 50:50, more preferably 3:97 to 40:60, and even more preferably 5:95 to 30:70. It may be preferable.

  It may be preferred that the kit according to the invention comprises at least one mixer, such as a static mixer. The mixer allows the first and second compositions to be effectively mixed. However, even if the kit according to the present invention does not include a mixer, the user of the kit mixes the first and second compositions, respectively discharged or dispensed from the first and second containers, for example by hand. Thus, non-uniform (ie, non-uniform or non-homogeneous) compositions can be prepared. Alternatively, the user can mix the first and second compositions using a shaker. The user of the kit can transfer the first composition from the first container to a second container containing the second composition and then shake to prepare a non-uniform composition. Also, the kit user can transfer the second composition from the second container to the first container containing the first composition and then shake to prepare the non-uniform composition . The mixing is preferably carried out in the presence of air.

  Non-uniform (i.e., non-uniform or non-homogeneous) compositions may be characterized by the presence of air bubbles, particles, small aggregates, or any combination thereof. The appearance of the non-uniform composition may be similar to that of a so-called smoothie.

  The non-uniform composition may comprise air bubbles having a size of at least 2 mm to 5 mm. Also, the size of the air bubbles may be less than 2 mm, or even up to 5 mm in some cases. If present, the bubbles are present in a complete mass having a non-homogeneous distribution such that some portions may have more bubbles than other portions.

  Non-uniform compositions may comprise particles having a size of at least 1 mm to 2 mm. The size of the particles may be less than 1 mm, or even up to 2 mm in some cases. When present, the particles are present in complete chunks with a homogenous distribution, giving a frosty appearance close to smoothies and Slushed links.

  The non-uniform composition may comprise aggregates having a size of at least 2 mm to 5 mm. The size of the aggregates may be less than 2 mm, or even up to 5 mm in some cases. If present, aggregates are present in complete chunks with a non-homogeneous distribution such that some portions may have more aggregates than other portions.

(First composition)
The first composition comprises at least one hydroxyalkyl modified starch. While a single type of hydroxyalkyl modified starch may be used, two or more different types of hydroxyalkyl modified starch may be used in combination.

  The hydroxyalkyl modified starch may be in the form of a powder. In other words, the hydroxyalkyl modified starch may be in the form of particles. In this case, the particle size of the hydroxyalkyl modified starch is not limited.

  The hydroxyalkyl modified starch is based on base starch. Base starch is intended herein to include all starches derived from any natural source, any of which may be suitable for use herein. Natural starch is herein found in nature. Further preferred are starches derived from plants obtained by standard breeding techniques including crossbreeding, transposition, transposition, transformation, or any other method of genetic or chromosomal engineering to include variations thereof. is there. In addition, starches derived from plants grown from artificial mutations and mutations of the above generic starches, which can be produced by mutational breeding, a standard method known in the art, are also suitable herein. is there.

  Typical starch sources are cereals, tubers, roots, pods and fruits. Natural sources include maize (maize), pea, potato, sweet potato, banana, barley, wheat, rice, oats, sago, amaranth, tapioca (cassava), mulberry, waxy varieties of sorghum and sorghum and their low It can be a variant of amylose and high amylose. As used herein, the term "low amylose" starch is intended to include starch containing about 10 wt% or less, in particular 5 wt% or less, more specifically 2 wt% or less of amylose. As used herein, the term "high amylose" starch is intended to include starch containing at least about 50% by weight, in particular at least about 70% by weight, more particularly at least about 80% by weight amylose. High amylose starches may be preferred.

  The hydroxyalkyl modified starch may be pregelatinized. Techniques for achieving alphalation and alphalation are known in the art and are disclosed, for example, in US Pat. Nos. 4,465,702, 5,037,929, 5,131,953 and 5,149,799. See also Chapter XXII-"Production and Use of Pregelatinized Starch", Starch: Chemistry and Technology, Vol. III-Industrial Aspects, R. L. Whistler and E. F. Paschall, Editors, Acadmic Press, New York 1967. The term pregelation is intended to mean puffed starch particles with loss of birefringence and / or Maltese cross in polarized light. Such pregelatinized starch derivatives are substantially soluble in cold water without cooking. In this context, "soluble" does not necessarily mean the formation of a true molecular solution, but may also mean a colloidal dispersion. In one embodiment, the starch is fully pregelatinized.

  Pregelatinized hydroxyalkyl modified starch can be easily and rapidly dissolved in cold water.

  Pregelatinization can be achieved by methods including, but not limited to, drum drying, extrusion and spray drying. In one embodiment, an extrusion method is utilized to simultaneously heat and dry the starch (see, eg, US Pat. No. 3,137,592). This method utilizes physical treatment of the starch / water mixture under high temperature and pressure which results in gelatinization of the starch and then swelling with sudden evaporation of water after leaving the nozzle.

  In one embodiment, the alphalation is completed to obtain good solubility and to remove undissolved particles that can give the composition an unpleasant sandy feel.

  In one embodiment, the starch is predominantly native starch granules. An aqueous dispersion of a pregelatinized starch derivative having a predominantly native particulate structure is typically more uniform than an aqueous dispersion of a non-particulate starch which may have a somewhat textured feel. It has a smooth texture. In the case of pregelatinized starch with a natural granular structure, the natural internal structure of the hydrogen bonds is broken but the external shape or form is maintained.

The hydroxyalkyl modified starch may be crosslinked. Crosslinking of the starch chains can be achieved by means of suitable crosslinking agents, ie difunctional compounds. In one embodiment, the crosslinking method used is a phosphorylation reaction, in which starch is reacted with phosphorus oxychloride, phosphorus pentoxide and / or sodium trimetaphosphate. Two starch chains are crosslinked by anionic PO groups. The anionic character of the crosslink sites aids in the emulsion stabilization action of the starch used according to the invention. In another embodiment, the crosslinking method uses a C ₄ -C ₁₈ alkane or alkene dicarboxylic acid, including but not limited to C ₄ -C ₈ alkanedicarboxylic acids, exemplified by adipic acid. The alkane or alkene dicarboxylic acid links the two starch chains by an ester bond. It may be linear or branched. The derivatives can be obtained, for example, by reacting starch with a mixed anhydride of dicarboxylic acid and acetic acid. In one embodiment, less than 0.1 wt% crosslinker is used based on dry starch. In another embodiment, about 0.06 to 0.1 wt% crosslinker is used based on dry starch.

  The alkyl portion of the hydroxyalkyl modified starch may have 2 to 6 carbon atoms, preferably 3 to 5 carbon atoms, more preferably 3 or 4 carbon atoms.

  The position of the hydroxyl group attached to the starch main chain via an alkyl group such as 2 to 6 carbon atoms in the alkyl group is not critical and may be from alpha to omega. In a preferred embodiment, the degree of substitution of hydroxyalkylation is about 0.08 to 0.3. The degree of substitution is the average number of substituted OH groups of starch molecules per anhydroglucose unit. Non-limitingly, as with hydroxypropylation by reaction of starch with propylene oxide, hydroxyalkylation of starch can be effected by reacting native starch with an alkylene oxide having a suitable number of carbon atoms . The starch used according to the invention can also contain more than one hydroxyl group per alkyl group.

  The hydroxyalkyl modified starch used in the present invention may be selected from the group consisting of hydroxyethyl starch, hydroxypropyl starch, hydroxyethyl starch phosphate, hydroxypropyl starch phosphate, and mixtures thereof.

  The methods used to prepare the hydroxyalkyl modified starch may be performed in any order. However, it is believed that one skilled in the art understands the benefits of the particular order. Hydroxypropylation, for example, is believed to occur prior to crosslinking, typically when the starch is crosslinked using phosphorous oxychloride, because the process of typical hydroxypropylation is , Because it is believed to destroy part of the achieved crosslinking.

The following may be mentioned as examples of hydroxyalkyl modified starches which are preferably used in the present invention.
Hydroxypropyl starch phosphate (pregelatinized corn starch) marketed by Akzo Nobel as Structure ZEA and XL, and
Modified (hydroxypropylated, pregelatinized, high amylose) corn starch marketed as AMAZE by Akzo Nobel.

  While not being bound by any theory, the use of the hydroxyalkyl modified starch in the first composition can be accomplished by mixing the first composition with a second composition described below. It is believed to be important in producing a non-identical final composition, because the hydroxyalkyl modified starch is believed to introduce air into the final composition when the first and second compositions are mixed. This is because it promotes the formation of bubbles and the like, and can make the final composition have a non-uniform appearance similar to a smoothie.
