Definitions

  • the present invention relates to an anti-microbial composition comprising a silver compound. More specifically, the present invention relates to an anti-microbial composition comprising a silver compound that can be used in personal care or home care compositions.
  • Silver has long been known to be anti-microbial. For instance, newborns were routinely swabbed with silver nitrate to prevent blinding eye infections until the past decade when nitrates were indicated to cause other problems. Silver is a broad-range anti-microbial agent that has proven effective against most harmful microorganisms present in everyday life such as E. coli, P. aeruginosa, S. aureus, P. acnes, A. niger, C. albicans, M. furfur. Silver sulfadiazine is commonly used as an antibiotic burn dressing in the form of a topical cream containing 1% silver sulfadiazine in micronized form.
  • US5688981 discloses novel silver chelating agents and surfactants that exhibit photosensitivity and anti-microbial activity.
  • the silver is chelated with ethylenediaminetriacetic acid (ED3A) or with N-acyl ED3A.
  • ED3A ethylenediaminetriacetic acid
  • N-acyl ED3A N-acyl ED3A.
  • Anti-microbial activity is exhibited even at very low silver levels.
  • EP2986698 discloses soap bars, in particular, high pH soap bars that provide improved biocidal activity against Gram-positive and Gram-negative bacteria in the relatively short contact times typical of bar use.
  • EP3099773 discloses cleansing compositions comprising a surfactant, an oligodynamic metal, a chelating agent, and a polymer having a group comprising a site having one or more lone pair of electrons.
  • the compositions disclosed provide improved biocidal activity against Gram-positive and Gram-negative bacteria in a relatively short contact time.
  • EP3099772 discloses an aqueous composition comprising an oligodynamic metal or ions thereof, a chelating agent, and free alkali less than 1 wt%.
  • JP5377003 discloses silver oxide mixed with phytic acid and a chelating agent such as ethylenediaminetetraacetic acid to improve the stability of the formulation and avoid discolouration due to UV radiation.
  • Phytic acid also called inositol polyphosphate, produces phytate anion at physiological pH. Both phytic acid and phytate ion have strong binding affinity to dietary minerals like zinc, calcium and iron inhibiting their absorption and leading to precipitate formation.
  • the present invention provides an anti-microbial composition comprising at least one silver compound, at least one amino acid, at least one fatty acid, and water.
  • the present invention provides the use of an anti-microbial composition as described herein in a personal care or home care composition, preferably as an anti-microbial agent.

  • the present invention provides a process for preparing an anti microbial composition as described herein, wherein the composition is prepared by mixing at least one silver compound, at least one amino acid, at least one fatty acid, and water.
  • Silver, zinc, copper and other metals are widely used in anti-microbial cleansing / cleaning compositions.
  • their oxides and some salts, especially that of silver are sensitive to pH, heat and light. Under such conditions, the active metal tends to discolour to form brown, gray or black particles. The particles are prone to settling and/or agglomeration.
  • most silver oxides and salts are poorly soluble in water.
  • Silver-based anti-microbial agents have very good anti-microbial effect. However, their efficacy often tends to gradually diminish over time, especially in the alkaline environment of a cleansing / cleaning composition.
  • the present invention thus provides a stable, non-toxic anti-microbial composition and a process for preparing the anti-microbial composition which is cost-effective and can be scaled up for commercial production.
  • the following definitions apply unless specifically stated otherwise. Unless otherwise stated, all percentages are by weight (w/w) of the respective component or the total composition, respectively.
  • wt.-% means percentage by weight; “vol.-%” means percentage by volume; “mol-%” means percentage by mole. Unless otherwise stated, all ratios are weight ratios (weight per weight). Preferably, references to ‘parts’ e.g. a mixture of 1 part X and 3 parts Y, is a ratio by weight. +/- indicates the standard deviation. All ranges are inclusive and combinable. Unless otherwise stated, all measurements are understood to be made at 23 °C and at ambient conditions, where “ambient conditions” means at approximately 1 atmosphere (atm) of pressure and at about 50 % relative humidity. “Relative humidity” refers to the ratio (stated as a percent) of the moisture content of air compared to the saturated moisture level at the same temperature and pressure.
