Abstract: A personal care composition includes an ozone-stressed yeast lysate; and a preservative, in which the preservative is selected from phenoxyethanol, isopropyl alcohol, benzyl alcohol, propylene glycol, butylene glycol, pentylene glycol, methylparaben, propylparaben, butylparaben, benzalkonium chloride, Quaternium 15, methylisothiazolinone, methylchloroisothiazolinone, DMDM hydantoin, imidazolidinyl urea, diazolidinyl urea, butylated hydroxytoluene, tocopherol, triclosan, chlorohexidine digluconate, and combinations thereof, and the ozone-stressed yeast lysate is produced by a method including exposing growing yeast to ozone by aerating the yeast for a time period of between five minutes and seventy-two hours with an aeration gas having an ozone concentration of from 0.0001 millimolar (mM) to 1.

Abstract: A method of producing yeast-polyphenol ferment extract includes growing the cells of a yeast of pichia genus in a growth media to late-logarithmic growth phase, in which the carbon source in the media is exhausted; exposing the cells to a non-cytotoxic dose of polyphenol; and extracting cytoplasmic and extra-cellular components of the exposed yeast cells from the growth media.

Abstract: A composition having effective broad spectrum preservation activity comprising benzyl alcohol, salicylic acid, sorbic acid and a compound selected from the group consisting of 1,3-propanediol, glycerin and combinations thereof.

Abstract: Compositions comprising metabolized conditioned growth medium and/or metabolized cell extract and methods of use are described. The metabolized conditioned growth medium and metabolized cell extract compositions may be formulated with an acceptable carrier into injectable or topical formulations, for example, as a cream, lotion or gel, and may be used in cosmeceutical or pharmaceutical applications. The metabolized conditioned growth medium and metabolized cell extract may also be further processed to concentrate or reduce one or more factors or components contained within the metabolized conditioned growth medium or metabolized cell extract. The growth medium may be conditioned by any eukaryotic cell. The metabolized conditioned growth medium and metabolized cell extract may be used to prevent or treat a condition, for example, a skin condition.

Abstract: Disclosed is a yeast/polyphenol ferment extract, and a personal care composition including the yeast/polyphenol ferment extract. Also disclosed is a method for preparing and using the yeast/polyphenol extract and the personal care composition.

Abstract: Disclosed is a cosmetic composition comprising prenylated isoflavonoid and a carrier, wherein the prenylated isoflavonoid is from about 0.0000001% to about 10%, preferably from 0.00001% to 1%, most preferably from 0.01% to 1%, by weight, based on the total weight of the composition. The active agent prenylated isoflavonoid induces a statistically significant upregulation of collagen 1A1 and elastin genes in normal human dermal fibroblasts. The composition is effective to stimulate the production of collagen and elastin and improve the appearance and condition of the skin.

Abstract: A personal care composition comprising leghemoglobin and at least one preservative selected from the group consisting of alcohols, glycols, parabens, hydantoins, quaternary nitrogen-containing compounds, isothiazolinones, aldehyde-releasing agents, and halogenated compounds. Preferably, the leghemoglobin is a nitrogen fixation root nodule extract providing a leghemoglobin concentration in the composition of between 0.0001% and about 10% based upon the total weight of the composition. Also disclosed is a method for preparing the personal care composition.

Abstract: Provided is a process of and product resulting from adding a sub-lethal amount of a peroxide, or said peroxide in combination with sub-lethal ultra violet radiation, to a growing culture of a yeast; observing the change in absorbance of the culture at 256 nm as a measure of the injury occurring to the yeast cells, and upon reaching a predetermined absorbance value, purifying the water-soluble yeast extract from the peroxide containing yeast culture. The resulting product has at least 1.5 respiratory units per mg dry weight and has significantly increased amounts of 15, 25 and 55 kilo Daltons (kD) molecular weight products compared to a Live Yeast Cell Derivative as determined by SDS slab gel electrophoresis. This product can be combined with a cosmetically acceptable carrier to provide a composition suitable for topical application to the skin.
