Definitions

  • the invention relates to skin-care compositions and methods for treating and/or preventing minor skin irritations containing a vitamin B 3 compound.
  • rashes are, generally, caused by allergies, exposures of the skin to periods of cold weather, or exposure to hot, humid conditions, such as washing dishes or the like, or exposure to irritating materials in topical products or ingredients (e.g., retinoiod, hydroxy acids, keto acids). These rashes can also be caused by excessive dryness of the skin without adequate skin moisturization.
  • an objective of this invention to provide a method for alleviating the symptoms of minor skin eruptions, redness, itchiness, dryness, rashes, and chapping in mammals, especially humans.
  • Another object of the present invention is to provide topical skin preparations for alleviating the symptoms of minor skin irritations comprising a safe and effective amount of a vitamin B 3 compound.
  • the present invention relates to methods of treating minor skin irritations comprising the steps of administering a safe and effective amount of a skin care composition comprising: a), at least above 2.5% of an anti-irritant skin agent selected from the group consisting of vitamin B3 compounds and mixtures thereof; and b). a dermatologically acceptable carrier for said vitamin B3 compound.
  • the present invention also relates to methods of treating minor skin irritation by applying a safe and effective amount of the skin care composition.
  • the present invention further relates to articles of manufacture comprising a skin care composition comprising from about 0.1% to about 40% of a vitamin B 3 compound in a package for said skin care composition in association with the information about and/or instructions on the use of vitamin B 3 compounds to treat minor skin irritations.
  • anti-irritant skin agent means an agent useful in alleviating the symptoms associated with minor skin irritation. Examples of such symptoms include, but are not limited to, pruritus, inflammation, contact dermatitis, minor rashes, burning, sunburning, stinging, redness, sensitivity, flaking/scaling, and the like.
  • Contact dermatitis specifically, is an inflammatory skin condition resulting either from the primary irritant effect of a substance or from sensitization to a substance coming in contact with the skin.
  • rashes are rashes due to occlusion, such as occurs on skin under a diaper, a feminine hygiene pad, an incontinent pad, a bandage, transdermal or cosmetic patches, etc.
  • Rashes can also occur in response to the adhesive(s) in bandages and similar devices. Additionally, rashes can occur in response to physical, biological or chemical insults to the skin such as from plants (e.g., Rhus genus of plants such as poison ivy, poison oak, poison sumac, and the like), plant materials (e.g., thorns, nettles, and the like), insects (e.g., bee stings, mosquito bites, fly bites, as well as bites from fleas, lice, mites, ticks, ants, and the like), spider bites, jelly fish stings, microbes, enzymes, extremes of pH, detergents, surfactants, fragrances, perfumes, preservatives, irritating cosmetic products, high levels of salts or metals such as nickel; some of these conditions occur on the skin (including the anal and genital tissue) in a diaper or incontinent pad environment, in which the contents and/or breakdown products of urine and feces contribute much of the biological and chemical insult
  • safe and effective amount means an amount of a compound or composition sufficient to significantly induce a positive benefit, preferably a positive skin appearance or feel benefit, including independently the benefits disclosed herein, but low enough to avoid serious side effects, i.e., to provide a reasonable benefit to risk ratio, within the scope of sound judgment of the skilled artisan.
  • compositions of the present invention comprise a safe and effective amount of a natural or synthetic vitamin B3 compound as the anti-irritant skin agent.
  • compositions of the present invention preferably comprise from about 0.1% to about 50%, more preferably from about 5% to about 40%, and still more preferably from about 5% to about 30%, most preferably from above 10% to about 30%, of the vitamin B3 compound.
  • vitamin B3 compound means a compound having the formula:

  • nicotinic acid material which is rubifacient at higher doses could be used at a lower dose to reduce the rubifacient effect.
  • Non-rubifacient esters of nicotinic acid include tocopherol nicotinate and inositol hexanicotinate; tocopherol nicotinate is preferred.
  • derivatives of the vitamin B3 compound are derivatives of niacinamide resulting from substitution of one or more of the amide group hydrogens.
