Description

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

The DIY (Do It Yourself) trend has also boomed in the beauty industry and many products have been launched over the past few years. On the other hand, many consumers are looking for healthy, clean and safe cosmetics. So the so-called “natural cosmetics” trend offers a lot of possibilities at the intersection of DIY and healthy, clean and safe cosmetics. Do-it-yourself cosmetic preparation gives consumers greater confidence in the health benefits, cleanliness, and safety of cosmetics.

Consumers need to prepare cosmetic products that appear edible. For example, some consumers desire to prepare their own cosmetic products that have an uneven, uneven or inhomogeneous appearance, similar to smoothies. The smoothie-like appearance can be explained by the presence of air bubbles, particles, small agglomerates, or any combination thereof. A smoothie-like aspect can further strengthen the concept of healthy, clean and safe cosmetics, because smoothies have multiple benefits in popular cultures such as detoxification, hydration, and revitalization. This is because it is well known that it is a health drink.

Kits according to the present invention can be prepared by those skilled in the art based on conventional packaging techniques. A kit according to the invention comprises at least first and second containers, each container separately containing the first and second compositions, respectively.

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

The kit may comprise dispensing or dispensing 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 contain 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 expelling the first and/or second composition. be able to.

The propellant is a liquefied gas, such as dimethyl ether (DME); Hydrogen, for example the compounds sold under the trade names Freon® and Dymel® by the company Dupont de Nemours, in particular the monofluoro sold especially under the trade name DYMEL 152A by the company DUPONT 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.

The propellant may or may not contact the first or second composition. If the propellant does not contact the first or second composition, it is possible to separate the first or second composition from the propellant with a film or sheet. For example, the first or second composition may be contained within a flexible bag located in the first or second container, while the propellant is contained in the flexible bag and the first or second container. can be included between

A non-uniform composition is prepared by mixing the first and second compositions 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:second composition that are mixed can vary from 0.1:99.9 to 99.9:0.1. The weight ratio of the first composition to the second composition to be mixed is from 1:99 to 50:50, more preferably from 3:97 to 40:60, even more preferably from 5:95 to 30:70. Sometimes it is preferable to have

A kit according to the invention may preferably comprise at least one mixer, such as a static mixer. A mixer can effectively mix the first and second compositions. However, even if the kit according to the invention does not include a mixer, the user of the kit may, for example, by hand mix the first and second compositions dispensed or dispensed from the first and second containers, respectively. As such, non-uniform (ie, heterogeneous or heterogeneous) compositions can be prepared. Alternatively, the user can use a shaker to mix the first and second compositions. A 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. Alternatively, a user of the kit can transfer the second composition from the second container to the first container containing the first composition and then shake to prepare a non-uniform composition. . Mixing is preferably carried out in the presence of air.

A non-uniform (ie, heterogeneous or heterogeneous) composition can be characterized by the presence of air bubbles, particles, small agglomerates, or any combination thereof. The appearance of uneven compositions may be similar to that of so-called smoothies.

A non-uniform composition may contain air bubbles having a size of at least 2 mm to 5 mm. Also, the bubble size may be less than 2 mm, or in some cases up to 5 mm. If present, the foam is present in complete mass with a non-homogeneous distribution such that some parts may have more foam than others.

A heterogeneous composition 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 in some cases up to 2 mm. When present, the particles are present in complete clumps with a homogenous distribution, giving a frosty appearance akin to smoothies and slushy drinks.

A non-uniform composition may comprise aggregates having a size of at least 2 mm to 5 mm. Aggregate size may be less than 2 mm, or in some cases up to 5 mm. When present, aggregates are present in complete mass with a heterogeneous distribution such that some parts may have more aggregates than others.

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

The hydroxyalkyl-modified starch may be in powder form. 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.

Hydroxyalkyl modified starches are based on base starch. Base starch, as used herein, is intended to include all starches derived from any natural source, any of which may be suitable for use herein. A native starch, as used herein, is one found in nature. Also preferred are plant-derived starches obtained by standard breeding techniques including crossbreeding, rearrangement, transposition, transformation, or any other method of genetic or chromosomal engineering to include variations thereof. be. In addition, starches derived from plants grown from artificial mutations and mutations of the above global starches that can be produced by known standard methods of mutation breeding are also suitable herein. be.

Typical starch sources are cereals, tubers, roots, pods and nuts. Natural sources include corn (maize), peas, potatoes, sweet potatoes, bananas, barley, wheat, rice, oats, sago, amaranth, tapioca (cassava), arrowroot, canna, and waxy varieties of sorghum and their low It can be amylose and high amylose variants. As used herein, the term "low amylose" starch is intended to include starches containing no more than about 10%, particularly no more than 5%, more particularly no more than 2%, by weight amylose. As used herein, the term "high amylose" starch is intended to include starches containing at least about 50%, particularly at least about 70%, more particularly at least about 80% by weight amylose. High amylose starch may be preferred.

Hydroxyalkyl-modified starch may be pregelatinized. Pregelatinization and techniques for achieving pregelatinization are known in the art and are disclosed, for example, in US Pat. See also Chapter XXII--"Production and Use of Pregelatinized Starch", Starch: Chemistry and Technology, Vol. The term pregelatinized is intended to mean expanded starch particles that have lost birefringence and/or the Maltese cross during polarized light. Such pregelatinized starch derivatives are substantially soluble in cold water without cooking. In this context, "soluble" does not necessarily imply the formation of true molecular solutions, but can also imply colloidal dispersions. In one embodiment, the starch is fully pregelatinized.

Pregelatinized hydroxyalkyl-modified starches are easily and rapidly soluble, even in cold water.

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

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

In one embodiment, the starch is predominantly native starch granules. Aqueous dispersions of pregelatinized starch derivatives having a predominantly pristine granular structure are typically more uniform than aqueous dispersions of starch without granular structure, which can have a slightly gritty feel. It has a smooth texture. For pregelatinized starches that have a pristine granular structure, the natural internal structure of hydrogen bonding is disrupted, but the contour or morphology is maintained.

Hydroxyalkyl-modified starches may be crosslinked. Cross-linking of starch chains can be achieved by suitable cross-linking agents, i.e. bifunctional compounds. In one embodiment, the cross-linking 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 cross-linking sites aids the emulsion stabilizing action of the starch used according to the invention. In another embodiment, the cross-linking method employs C ₄ -C ₁₈ alkane or alkenedicarboxylic acids, including but not limited to C ₄ -C ₈ alkane dicarboxylic acids, exemplified by adipic acid. Alkane or alkenedicarboxylic acids link two starch chains via an ester bond. It may be in the form of straight or branched chains. Derivatives can be obtained, for example, by reacting starch with mixed anhydrides of dicarboxylic acids 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, which is attached to the starch backbone via an alkyl group such as 2 to 6 carbon atoms in the alkyl group, is not critical and may be alpha to omega positions. In one preferred embodiment, the degree of substitution for hydroxyalkylation is about 0.08 to 0.3. The degree of substitution is the average number of substituted OH groups of the starch molecule per anhydroglucose unit. Hydroxyalkylation of starch can be effected by reacting native starch with an alkylene oxide having the appropriate number of carbon atoms, such as, but not limited to, hydroxypropylation by reacting starch with propylene oxide. . Starches used in accordance with the present invention may also contain multiple hydroxyl groups 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 can be performed in either order. However, those skilled in the art will appreciate the benefits of a particular order. For example, hydroxypropylation is typically considered to occur prior to cross-linking when starch is cross-linked using phosphorus oxychloride because the typical hydroxypropylation process is , is believed to destroy some of the cross-linking achieved.

Examples of hydroxyalkyl-modified starches that are preferably used in the present invention include:
Hydroxypropyl starch phosphate (pregelatinized corn starch), marketed as Structure ZEA and XL by Akzo Nobel, and
Modified (hydroxypropylated, pregelatinized, high amylose) cornstarch marketed as AMAZE by Akzo Nobel.

Without being bound by any theory, it is believed that the use of hydroxyalkyl-modified starch in the first composition can be achieved by mixing the first composition with the second composition described below. It is believed to be important in producing a non-like final composition because upon mixing the first and second compositions, the hydroxyalkyl-modified starch incorporates air into the final composition. , because it promotes the formation of bubbles and the like and can give the final composition an uneven appearance similar to a smoothie.
