The nPAS of the present invention are particularly suited for use in, inter cilia, natural, green, organic, sustainable, holistic, bio-degradeable, natureidentical homeopathic, eco-friendly, earth-friendly, environmentally safe, preservative-free, paraben-free and non-toxic products. And within those categories of products, the preservative alternatives of the present invention are particularly suited for use in, inter alia, personal care products, cosmetics, treatment, skin care and anti-aging products, cosmeceuticals, nutraceuticals, beauty foods, fragrance products, pharmaceuticals and food stuffs.
2. Related Art
This invention is related to the art of providing cosmetics with a preservative to suppress, in particular, microbiological growth on the cosmetics. While the preservatives of this invention can be used in virtually any cosmetic, this is particularly true of water-in-oil and oil-in-water preparations. They can be present as emulsions, gels or soft solids. Conventional lipsticks are examples of soft solids. Commonly employed preservatives include hydantoin derivatives and the family of compounds generally referred to as parabens. U.S. Pat. Nos. 5,037,843 and 5,965,594 are representative of patents I nthis field of cosmetic preservatives.
BACKGROUND OF THE TECHNOLOGY
The demand for organic/natural consumer products continues to increase world wide. This demand has paralleled the increasingly expansive recognition of the health benefits and environmental benefits of products falling into one or more of the categories including: natural, green, organic, sustainable, holistic, bio-degradeable, nature-identical, homeopathic, ecofriendly, earth-friendly, environmentally safe, preservative-free, paraben-free and non-toxic. For example, the natural & organic sector(s) has become one of the fastest growing in the North American personal care and cosmetics industries, with sales increasing by approximately 20% per year. Healthy market growth rates have been projected to increase the market share of natural & organic products at least 15-20% of the total sales for cosmetic & toiletry products in the coming years. Global sales of natural & organic cosmetics are rapidly increasing with some sources projecting projected revenues approaching US$7 billion in 2008.
Apart from an influx of new product launches, a major driver of market growth appears to be the mainstreaming of natural & organic products. Distribution in mainstream retailers is increasing as retailers react to market demand.
Increasing market demand and the absence of official standards have led to much consumer confusion within the marketplace as to what constitutes “natural” or “organic” products and the introduction of many pseudo-natural products. Nonetheless the proliferation of organic and natural personal care products is leading to increased consumer awareness and scrutiny of the ingredient composition. With this enhanced knowledge and understanding, the demand for products that contain increased concentrations of natural extracts, botanicals and ingredients derived from natural sources coupled with a reduction of (and if possible/practical, the elimination of) ingredients that are known or suspected health threats (e.g., pesticides, toxins, antibiotics, etc.). This consumer demand has recently led to the private sector establishment of ethical and certified organic ingredients. Indeed, a growing number of companies have recently initiated processes through which one can receive third-party certification of the “organic” character of products.
Similarly, exceptionally high market growth rates are pushing global organic food & drink sales towards US $40 billion per year. With demand outpacing supply, supply shortages have been experienced. Undersupply is most evident in the North American region where empty retailer shelves have become commonplace for some product categories. Several European countries are also experiencing supply shortages this year as consumer demand for organic foods has escalated.
Although there are very few consistent definitions for what constitutes “organic” or “natural,” there is a clear market demand for products that do not include chemicals that are not essential to the product functioning or character of the products in question and, where required, that the specific ingredients be non-toxic, environmentally friendly, bio-degradable, naturally derived, organic and/or derived from sustainable resources when possible.
Preservatives perform a key function in modern manufacture, marketing and retailing. Most pharmaceuticals, foods, fragrance products, cosmeceuticals, nutraceuticals, cosmetics, treatment, skin care and anti-aging products, personal care products, etc., commonly contain ingredients that are capable of supporting microbial growth and proliferation. Additionally, regardless of their use, these types of products typically contain water as one of the primary components. This water provides a medium in which microorganisms can survive and/or proliferate. Thus, these products by their very nature create an environment and viable medium for the proliferation of microbial organisms. Without the addition of some preservative agent, these types of products are susceptible to microbial contamination and proliferation.
By way of a representative non-limiting example, personal care products such as cosmetics and skin care products typically contain ingredient(s) (i.e., preservatives) which inhibit, or otherwise limit, microbial proliferation thereby protecting the product from, for example, degradation/putrefaction. In addition, these ingredients serve to protect the consumer from problems attending microbial contamination. Thus, preservatives provide a benefit to the manufacturer (e.g., providing a longer sustainable shelf-life) and a benefit to the consumer (e.g., stable products, reduction of contamination and/or infection and consistent product performance).
Emulsion systems (for example, oil-in-water (o/w), water-in-oil (w/o, multiple emulsions (for example water-in-oil-in-water (w/o/w) and oil-in-water-in-oil (o/w/o) systems), liposomal systems and aqueous-based liquid, gel or suspension systems are the major product forms used for topical delivery systems in cosmetic, skin care, personal care, OTC pharmaceutical, ophthalmic, otic, dermatological and other prescription pharmaceutical products. Each of these delivery systems contains water, as well as ingredients that can support and/or sustain the growth of microorganisms such as bacteria, yeast and molds. These products therefore typically contain preservatives to kill or at least inhibit the growth of microorganisms, usually in amounts intended to provide efficacy while hopefully avoiding any adverse effect on the user. Government regulatory agencies commonly regulate the concentrations of the preservatives employed, doing so to protect the consumer by reducing the potential for, inter alia, irritation and/or allergic sensitization.
The increasing desire for natural and/or organic products creates and inherent conflict with the need to inhibit microbial growth and proliferation. Traditional and commonly employed preservative agents are, by their very nature, toxic. Some of the more commonly used preservatives in topically applied products include the following materials listed alphabetically according to their International Nomenclature for Cosmetic Ingredients (Na) name: Benzoic Acid (and salts), Benzyl Alcohol, 2-bromo-2-nitropropane-I,3-diol, Chlorhexidine, Chloroxylenol Dehydroacetic Acid (and salts), Diazolidinyl Urea, DMDM Hydantoin, Imidazolidinyl Urea, Isothazolinones, Paraben Esters, Phenethyl Alcohol, Phenoxyethanol and Quaternim-15.
The esters of p-hydrobenzoic acid are known as parabens, and include methyl, ethyl, propyl and butyl esters. Higher esters are even more active then the butyl esters, but decreasing solubility makes them less desirable to use. Benzoic acid may be used either as the acid, or as a salt such as sodium benzoate. There is an increasing consumer demand for products that do not contain paraben preservatives.
Formaldehyde has been another prominent and potent antimicrobial agent; other agents gradually donate or release formaldehyde. This category of preservatives includes, for example, imidazolidinyl urea, diazolidinyl urea, DMDM hydantion and Quatemim-15. Many of the topically applied products use either imidazolidinyl urea (Germall 115® from Sutton Labs) or diazolidinyl urea (Germall II® from Sutton Labs), alone or in combination with other agents such as parabens. Some countries, such as Japan, restrict the use of “formaldehydedonating” preservative agents, such as imidazolidinyl urea and diazolidinyl urea, and prohibit the use of “formaldehyde-releasing” preservative agents such as Quaternium-15 and DMDM Hydantoin. Other countries, such as the European Union, are not as restrictive about the types of preservative agents that can be employed, however, they limit the concentration of each agent included in a product. As with paraben compounds, there is an increasing consumer demand for products that do not contain formaldehyde donating/releasing preservatives.
The choice of preservative agents to incorporate into a product and/or formulation, and the amount of each agent required for efficacy, typically varies from one product/formulation to another. The effective amount is commonly determined empirically by preservative efficacy testing (e.g., storage studies, challenge tests, etc.). Despite the expertise and knowledge in the art of formulation, each combination of preservative agents and adjuvants used in a particular formulation should be tested for effectiveness against a broad range of microorganisms. This is because it is often not well understood why a particular combination of preservative agents and adjuvants will be effective within a given formulation, environment, etc. Moreover, given the potential for irritation and sensitization from preservative agents, an additional objective of the manufacturer/formulator is to create a preservative system that does not cause adverse reactions and/or complications.
An ideal preservative system has a broad-spectrum of activity against all types of microorganisms, including yeast and mold, and gram-positive and gram-negative bacteria. The preservative is also ideally effective at low concentrations, to minimize expense and avoid irritation and/or sensitization reactions. The ideal preservative should exhibit a good solubility profile in both oil and water phases of an emulsion to ensure that the preservative is present in that portion of the product where it can be effectively assimilated by the microorganisms.
The preservative should also be compatible with the other ingredients in the formulation, and not react with or otherwise be inactivated by those ingredients. The preservative is ideally colorless and odorless, and remains so throughout the intended shelf-life of the product. It should also be stable throughout the expected life of the product, because many microorganisms can lay dormant in the composition until conditions are later appropriate for growth. If a preservative was unstable and degraded over the shelf-life of the product, contamination could occur once the preservative concentration fell below the threshold necessary to inhibit the growth of the microorganisms. Furthermore, the preservative is ideally stable to any changes in temperature and/or pH encountered during the manufacturing and packaging process, as well as the storage conditions encountered both prior to and after sale to the end user.
The preservative should also be safe, without exerting undesired biological effects on human skin cells. Even at typical use concentrations, many preservatives have the capacity to cause irritation and/or sensitization. Furthermore, since the concentrated preservative agents must be handled and incorporated into the product during the manufacturing process, these materials must not present an insurmountable hazard to the production workers during the manufacture/formulation processes.
The preservative agents are preferably easy to handle in their bulk state, prior to incorporation into a formulation, and inexpensive to use. More expensive preservatives are ideally effective at lower concentrations for cost effectiveness criteria.
No single preservative agent fulfills all of these criteria, and the requirements become even more complex when regulatory requirements are added to the criteria, and entirely unmet with respect to the natural/organic requirement. Formulation scientists working in collaboration with microbiologists and analytical chemists continue to expend a significant amount of effort in developing adequate preservative systems in an attempt to satisfy both practical and regulatory requirements.
Developing a novel, safe, naturally derived I organic, and internationally acceptable preservative alternative is a complex problem that has been addressed by the present invention. The following description of the preservative alternative is meant to be representative of the overall technology. Anyone skilled in the art of formulation and/or microbiology will see variations and potential applications for this technology beyond the examples provided herein. Therefore, the present invention is not limited to the examples or specific formulations represented by these examples, but instead it will be understood that the examples and explanations disclosed herein are provided only for illustrative purposes and that in view of the instant disclosure, various modifications of the present invention will be apparent to those skilled in the art and are to be included within the spirit and purview of this application and the scope of the appended claims.
