Metal nanoparticle agglomerates in various forms may be utilized to promote infection control. Antiseptic substrates may comprise a base substrate and metal nanoparticle agglomerates adhered thereto. Metal nanoparticle agglomerates upon the antiseptic substrates may be contacted with a skin penetration, a skin injury, a burn, a site to be subjected to a skin penetration, or an active skin infection to provide infection control against at least one infective agent. The antiseptic substrates may also facilitate water purification in some cases. Antiseptic fluid formulations comprising a fluid medium having metal nanoparticle agglomerates dispersed therein may be configured for topical or oral use and may similarly afford infection control. Creams, ointments, balms, salves, gels, and liquids or liquid suspensions containing metal nanoparticle agglomerates may be effective for promoting infection control and/or for treating an active infection.

The invention relates to an oil-in-water emulsion containing 15.0 to 30.0 wt.-% ethanol.

Provided is a growth inhibitor for Clostridioides difficile. A growth inhibitor for Clostridioides difficile, comprising killed Enterococcus faecalis. Also provided are a parenteral pharmaceutical preparation, a bactericide, a disinfectant, an antibacterial agent, a sanitizer or a detergent for inhibiting the growth of Clostridioides difficile.

Provided a method of sterilization by ultraviolet irradiation whereby effects on the human body can be mitigated and an odor that arises after ultraviolet irradiation can be controlled. The sterilization method includes: a step (a) of irradiating a skin of a hand or arm with ultraviolet having a wavelength of 200 nm or more and 230 nm or less; and a step (b) of applying a topical skin preparation, cosmetic, or aqueous solution containing at least one amino acid or amino acid derivative selected from an amino acid group A to a region of the skin irradiated with the ultraviolet. The amino acid group A includes valine, leucine, isoleucine, glutamic acid, arginine, serine, aspartic acid, proline, and glycine.

Antimicrobial compositions and methods for inhibiting microbial growth are disclosed. The antimicrobial compositions can include an acyl lactylate, a glycol, and a carrier. The carrier can include water. Water can form at least about 90% by weight of the composition.

The present invention relates to disinfecting products and compositions and formulations. More specifically, the invention relates to antimicrobial compositions, formulations containing the compositions, products containing the compositions or formulations, methods of preparation, and processes for disinfecting surfaces with the compositions or formulations.

The purpose of the present invention is to provide: a virus inactivating agent that exhibits an effect at an amount that does not cause skin irritation; and an external skin preparation composition containing said virus inactivating agent. The present invention relates to: a virus inactivating agent containing, as an effective component thereof, at least one selected from mint oil, eucalyptus oil, rosemary oil, sage oil, tea tree oil, shell ginger oil, peppermint oil, lemongrass oil, cajeputi oil, niaouli cineole oil, lime oil, lemon oil, lemon verbena oil, St. John's wort oil, ravintsara oil, rosewood oil, Melissa/lemon balm oil, myrrh oil, mandarin oil, vetiver oil, frankincense oil, citronella oil, cardamom oil, Angelica oil, and cationized starch; and an external skin preparation composition containing the same.

This invention relates to oral care compositions comprising zingerone, bisabolol, a stannous ion source, zinc oxide, and zinc citrate, as well as to methods of using and of making these compositions.

A method for detaching, removing or otherwise disrupting bacteria or biofilm by applying with pressure an antimicrobial wash. The antimicrobial wash contains a biguanide compound or mixtures thereof.

An antiseptic composition comprising a multivalent cationic antiseptic present in an amount of 0.05 to 0.5 percent based upon the ready to use composition; an anionic compound which is water soluble in an amount of at least 0.1 grams in 100 grams water at 23 deg C., wherein the anionic compound is present at a concentration which would result in precipitation of the multivalent cationic antiseptic in the composition without a solubilizing surfactant present; wherein the composition, with the antiseptic, surfactant and anionic compound combined with each other, is free of precipitate.
