Personal care product preservation systems and methods comprise the use of wasabi and a co-preservative, such as pentylene glycol or a mixture of undecylenoyl glycine and capryloyl glycine to preserve a personal care product. The wasabi provides a natural preservative effect that inhibits the growth of microbes that can otherwise flourish in personal care products. The personal care products can be in the form of emulsions, gels, serums, solutions, and c88g vehicles suitable for use with personal care products, such as toners, lotions, creams, and the like.
Personal care product preservation systems and methods may also comprise the mixture of undecylenoyl glycine and capryloyl glycine to preserve a personal care product. For purposes of disclosure, the foregoing application is incorporated herein in its entirety. The Field of the Invention .
The present invention relates generally to all-natural compositions and methods for preserving personal care products. More particularly, the invention c8b to the use of wasabi and it derivatives as a preservative for personal care products. The Relevant Technology . Water-based personal care products, such as lotions and toners, provide an hospitable environment for microbial growth. How quickly the microbes grow and render the product unsuitable for use is a function of various factors, including the susceptibility of individual products to microbial growth, the presence or absence of preservatives, and the storage condition of the personal care product after the microbial contamination first occurs.
As a result, personal care products have defined shelf lives to ensure a product’s quality. These shelf lives typically include two critical dates: For example, a product may have a two year expiration date after a product is opened by a consumer, subject to an absolute shelf life of three years. Obviously, the longer a product’s shelf life the greater its value, both to a manufacturer concerned about product quality and maintaining inventories and to a consumer concerned about lipacidr quickly a product must be consumed.
Lipcide is therefore a constant need to develop effective methods to deter microbial growth and thereby extend product shelf lives.
Typically, artificial preservatives are used to extend product shelf lives. There is a growing consumer awareness and fear, however, that artificial preservatives may contain damaging chemicals whose effect on users or the environment may be harmful, either individually over time or in a cumulative effect with other chemicals.
There is therefore also a need for products that preclude microbial growth without c8v use of artificial preservatives. One x8g effective approach is to carefully package a product in sanitary conditions and then hermetically seal the product to prevent the introduction of microbes. This only prevents product degradation prior to consumer use, however, as an un-preserved product may quickly degrade after an initial consumer use, such as after microbial-laden fingers contact the product.
Alternatively, intricate product dispensing systems, such as pumps, may provide effective methods to delay contamination but cannot slow microbial growth once contamination occurs.
The isothiocyanate compounds may be manufactured synthetically or isolated from natural plant matter. In view of the foregoing, there is a continuing need for more organic and natural systems and compositions to preserve personal care products.
Wasabi has been found to provide a natural preservative effect that inhibits the growth of microbes that can otherwise flourish in aqueous based personal care products. The personal care products can be in any desired form, including emulsions, gels, serums, solutions, and other vehicles suitable for use with personal care products, such as toners, lotions, creams, cleansers, refiners, and the like.
Unlike artificial preservatives, including synthesized compounds and single compounds isolated from natural products, wasabi is a true natural product. Accordingly, in one personal care product preservation system according to the invention, a personal care product is blended with a preservative composition comprising wasabi and pentylene glycol.
One preferred form of wasabi is wasabia japonica root extract. Suitable concentrations of the preservative may vary according to the personal care product formulation being preserved.
For example, the concentration of water is often an important variable because microbial growth generally follows water concentrations.
The pentylene glycol provides a co-preservative effect. According to another embodiment of the invention, a personal care product preservation system comprises a personal care product and a preservative composition comprising wasabia japonica, undecylenoyl glycine, and capryloyl glycine.
The undecylenoyl glycine and capryloyl glycine are collectively believed to provide a co-preservative effect. The use of other organic co-preservatives, including variations and derivatives of the foregoing, is also contemplated by the invention.
Similarly, a method according to the invention for inhibiting microbial growth in a personal care product comprises mixing a personal care product, a wasabia root japonica extract, and at least one additional co-preservative selected from the group consisting of pentylene glycol, undecylenoyl glycine, and capryloyl glycine.
These and other advantages and features of the present invention will become more fully apparent from the following description and appended claims, or may be by the practice of the invention as set forth hereinafter. The wasabi provides a natural preservative without the use of undesirable artificial preservatives. When used in selected concentrations and pH ranges and with appropriate co-preservatives, the wasabi can be an effective preservative. The optional co-preservative, for example pentylene glycol or a mixture of undecylenoyl glycine and capryloyl glycine, helps preserve the personal care product and ensure that only safe levels of wasabi need to be used.
The use of a co-preservative is important because certain personal care products may require high preservative concentrations to prevent all microbial growth. Because high concentrations of wasabi may cause skin irritation, the present invention uses co-preservatives to allow effective microbial growth control at low wasabi concentrations.
According to another embodiment of the invention undecylenoyl glycine and capryloyl glycine can be used without wasabi to inhibit microbial growth in personal care products.
These two compositions have been found to have a synergistic effect that can provide an effective approach to inhibiting microbial growth. The personal care products can be in any desired form including emulsions, gels, serums, solutions, and other vehicles. Such vehicles are commonly used in consumer products such as toners, lotions, creams, refiners, cleansers, and the like. In addition to the surprising effectiveness of wasabi as a preservative for personal care products, wasabi has the advantage of being an all-natural product.
In contrast, conventional preservatives typically comprise synthetic chemical compounds, and are therefore disfavored by many consumers for their potential health and environmental risks. The use of wasabi as an alternative preservative to synthetic chemical compositions provides not only reduced health and environmental risks, to the extent that such exist, but also satisfies the consuming public’s demand for natural products.
Additional advantages of the present invention will become readily apparent to those skilled in the art from the following detailed description, wherein currently preferred embodiments of the invention are shown and described in the disclosure. As will be realized, the invention is capable of other and different embodiments, and its several details are capable of modifications in various obvious respects, all without departing from the invention.
Accordingly, the description is to be regarded as illustrative in nature, and not as restrictive. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be obvious, however, to one skilled in the art that the present invention may be practiced without these specific details. In other instances, well known aspects of personal care products have not been described in particular lipacidw in order to avoid unnecessarily obscuring the present invention.
The wasabi plant grows about knee high, is semi aquatic, and produces a thickened stem in a similar fashion to a small brussel sprout. As the stem grows the lower leaves fall off.
This stem has a very pungent smell and flavor when made into a paste, which is commonly used as a condiment for sushi. Wasabi can be produced both as a ground grown or water grown plant, although water-grown plants generally produce a higher quality product than the ground grown plants. Like its relatives in the cabbage family, wasabi owes its pungency to isothiocyanates. In addition, two glucosinolates have been identified in the root: Further trace components are 6-methylthiohexyl isothiocyanate, 7-methylthioheptyl isothiocyanate and 8-methylthioocytl isothiocyanate.
These lpacide are generally classified as omega-methylthioalphyl isothiocyanates. One preferred form to include wasabi in the formulations of the present invention is wasabia japonica root extract, which can be obtained from Active Concepts, LLC in S.
The wasabia japonica root is extracted using a method proprietary to Active Concepts that involves the following general methods: Other methods of manufacturing wasabi extract include enzymatic extraction or sequentially macerating plant matter in water or other solvents and then lioacide the plant matter in a solvent extraction process.
Despite the effectiveness of wasabi as a preservative, it has been determined that it is most effective when utilized in x8g with at least one co-preservative. The use of a co-preservative is advantageous because it enables the use of lower wasabi concentrations than might otherwise be lipacise to control microbial growth. When high wasabi concentrations are required to preserve a product, skin irritation with clinical manifestations, e. Cg use of co-preservatives thus allows the selection of an optimized wasabi cg that balances the desired preservative action with minimized skin irritation.
One such co-preservative is pentylene glycol C  5 H 12 O 2an organic compound that is commercially available from Dragoco, Inc.
Although pentylene glycol has been used in combination with chemical preservatives, such as parabens, its synergistic co-preservative effect with natural substances has not been heretofore established.
Another co-preservative is the combination of capryloyl glycine and undecylenoyl glycine.

Glycines are amino acids commonly found in plants, and capryloyl glycine C  10 H 19 NO 3 is the acylation product of glycine with caprylic acid chloride. Undecylenoyl Glycine is the acylation product of glycine with n-undecylenoyl chloride.
Other suitable natural co-preservatives, including variations and derivatives of the foregoing, may also be used and are compatible with the present invention. Suitable concentrations of wasabi to preserve personal cg products ranges from a low of about 0. In the case of low water content formulations, which generally has a lower susceptibility to microbial growth or where wasabi c8f be used to boost the effect of other preservatives or co-preservatives, a lower range of wasabi is also effective, preferably from about 0.
Suitable concentration ranges for co-preservatives will vary depending on the selected co-preservative, the concentration of wasabi, and the product being preserved.
The systems of the invention can employ various vehicles, or mediums, depending on the particular form of personal care product. Common vehicles include solutions, emulsions, gels, and serums, each of which can be used to provide the desirable form for consumer products, such as toners, lotions, creams, cleansers, refiners, and the like. These varied vehicles enable the present invention to be used in the wide range of personal care products that are commercially available.
Gels and serums are similar vehicles, the main difference being that gels tend to have a high viscosity whereas serums have a low viscosity. Oil and water emulsions can be either oil-in-water emulsions or water-in-oil emulsions, either one being suitable for use with consumer care products.
However, the ratio of oil-to-water can greatly affect the concentration of preservatives required. This is because microbes tend to flourish or die, depending on the amount of water present in a formulation. Typical components of the herein discussed vehicles solutions, gels, serums, and emulsions vary depending on the particular formulation, but may include water, emulsifiers, co-emulsifiers, thickeners, surfactants, gellants, humectants, moisturizers, botanicals, solubilizers, acidulents, neutralizers, emollients, organic sunscreens, inorganic powders, astringents, chelating agents, solvents, detergents, essential oils, and colorants.
In addition, it has been determined that the vehicles of the herein disclosed systems will preferably have a pH value in a range from about 2 to about 8, more preferably from about 3 to about 7, and most preferably from about 5 to about 6.
Methods of preserving personal care products involves the application of the foregoing teachings regarding the use of wasabi preservative compositions to inhibit microbial growth in personal care products. Hence, the methods involve mixing the appropriate amounts of wasabi and the desired co-preservative into the chosen vehicle of the personal care product, such as solutions, gel, serum, or emulsion.
Other packaging techniques sealed containers, sanitary pumps may also assist in inhibiting microbial growth. The following examples are given to illustrate the present invention, and are not intended to limit the scope of the invention.
