preparation example Construction

[0118] Water used in the preparation of commercially suitable oral compositions should advantageously have a low ion content and be free of organic impurities. Water can comprise up to about 99% by weight of the aqueous composition. These amounts of water include added free water and water introduced by other substances, such as by sorbitol.

[0119] The present invention may also include alkali metal bicarbonates, which may serve a number of functions including grinding, deodorizing, buffering, and adjusting pH. Alkali metal bicarbonates are soluble in water and tend to release carbon dioxide in aqueous systems unless stabilized. Sodium bicarbonate, also known as baking soda, is a commonly used alkali metal bicarbonate. The compositions of the present invention may comprise from about 0.5% to about 30% by weight of an alkali metal bicarbonate.

[0120] The pH of the present compositions can be adjusted through the use of buffering agents. As used herein, a buffering agent...

Embodiment I

[0140] Example I: Essential Oil Blends

[0141] Compositions Ia to Ik shown below were prepared by blending the parent essential oil compound and one or more derivatives with other essential oils or extracts. These essential oil blends can be used as a base flavor or base fragrance in personal care compositions such as those exemplified herein.

[0142]

Embodiment II

[0143] Example II: Dentifrice Compositions

[0144] Dentifrice compositions according to the invention IIa-IIo are shown below, the amounts of ingredients being in % by weight. These compositions are prepared using conventional methods. In consumer sensory tests, oral care compositions according to the present invention are rated as having a pleasant, long-lasting, natural, lightly herbaceous taste and providing cleansing and refreshing of the oral cavity without a burning sensation and unpleasant aftertaste.

Abstract

Compositions containing one or more derivatives of essential oil compounds for use in personal care compositions, such as compositions for oral, throat and skin care are disclosed. These derivatives include acetals of parent essential oil aldehydes and ketones; esters or ethers of parent essential oil alcohols and phenolics; and esters of parent essential oil acids. Examples of parent essential oil aldehydes and ketones include citral, cinnamic aldehyde, anisaldehyde, vanillin, ethyl vanillin, heliotropin, carvone, and menthone. Examples of parent essential oil alcohols and phenolics include thymol, eugenol, isoeugenol, dihydroeugenol, carvacrol, carveol, geraniol, nerol, vanillyl alcohol, heliotropyl alcohol, anisyl alcohol, cinnamyl alcohol and ss-ionol. Examples of parent essential oil acids include anisic acid, cinnamic acid, vanillic acid and geranic acid.; The present compositions comprising essential oil derivatives are useful as base flavor or base perfume for incorporation into personal care products and to provide other benefits including antimicrobial efficacy. Optionally the compositions will contain additional antimicrobially- or anti-inflammatory-effective components including those also derived from plant essential oils or synthetic versions thereof.

Description

field of invention [0001] The present invention relates to compositions comprising chemical derivatives of one or more plant essential oil constituent compounds and their use in personal care products, such as oral, throat and nasal care products, to provide benefits, including antimicrobial active and pleasant flavor and aroma that enhance consumer acceptance of the finished product. Background of the invention [0002] Consumers routinely use oral care products such as tooth powders and mouthwashes as part of their oral care hygiene regimen to provide both therapeutic and cosmetic hygiene benefits. Therapeutic agent benefits include dental caries prevention, which is typically delivered through the use of various fluoride salts; gingivitis prevention, which is achieved through the use of antimicrobial agents such as triclosan, stannous fluoride, or essential oils; or allergy control, It is carried out through the use of ingredients such as stannous fluoride, strontium chl...
