Definitions

  • brine solutions are used for various applications and these can frequently result in damage, or at least, irritation to the skin of a user if skin contact occurs.
  • brine is used throughout the specification to refer to solutions of various types of salts, typically but not exclusively, solutions of calcium chloride, calcium bromide, zinc bromide, zinc chloride, formates and/ or acetates or blends or mixtures thereof, and including what are called “heavy brines" being “super-saturated” solutions.
  • brine When brine is in contact with human tissue, it is believed to attack that tissue in a number of ways. Firstly, brine may act as an acid initially, as a hydrogen donor, attacking the tissue by altering its pH. Secondly, the brine can act as an astringent and de-moisturiser with long exposure. Thirdly, in extreme cases, the brine can act as an emulsifier of the fats and oil in skin tissue to complexes which are removed with the brine when the exposed skin tissue is washed.
  • an object of the present invention to provide an additive for brine and/or a method of treating brine which will avoid or at least obviate the above problems in the use of brine, or which at least will provide the public with a useful choice.
  • a method of treating brine which will at least alleviate its effect on human skin tissue comprising adding to the brine an epidermically effective amount of a surfactant, polymer and/or oil.
  • the method as immediately above defined includes epidermically effective amounts of at least two of the said surfactant, polymer and/or oil.
  • the method includes epidermically effective amounts of a surfactant, polymer and oil.
  • a method as defined in the paragraph immediately above includes, by volume;
  • one or more surfactants approximately 83 % to approximately 84%
  • one or more polymers approximately 6% to 7%; the above percentages being based on the total active ingredients.
  • an additive for brine to alleviate the effect of brine (as herein defined) on human skin tissue comprises an epidermically effective amount of a surfactant, polymer and/or oil.
  • the additive as defined immediately above includes at least two of the said surfactant, polymer and/or oil.
  • the additive as defined in either of the two paragraphs immediately above includes a surfactant, polymer and oil
  • an additive as defined in the paragraph immediately above has by volume and based on the total volume of the active ingredients:
  • one or more surfactants approximately 83% to 84%;
  • one or more polymers approximately 6% to 7 % .
  • an additive for brine as defined in any one of the eleven immediately preceding paragraphs is in the form of a cream, lotion, spray, liquid, cleanser or the like.
  • brines are used in various strengths, depending on the uses to which they will be put.
  • the brines will typically have an adverse effect on any human skin tissue with which they come into contact, which effect can range from merely skin irritation, erythema, producing redness, through to edema where the skin is ulcerated and swollen.
  • erythema producing redness
  • edema where the skin is ulcerated and swollen.
  • degrees of effect as well, so that a brine can produce severe erythema with beet redness and with eschar formation, or with severe edema producing swelling which can be more than 1 mm and can extend well beyond the initial area of exposure.
  • the present invention provides in one embodiment an additive which when applied to human skin tissue, is able to prevent or at least alleviate damage to human skin tissue with which it comes into contact.
  • the term "epidermically effective" as used throughout this specification has this meaning.
  • the additive of the present invention is believed to buffer 0 the brine insofar as it reduces or eliminates the pH effect on the skin, provides the skin with a moisturiser or at least prevents or limits the effect of the brine until it is able to be removed.
  • the additive of the present invention may be added ⁇ • ⁇ directly to the brine to protect against accidental or work-related exposure to the brine. Additionally or alternatively, the additive of the present invention, may it is envisaged, be used as a barrier, cream or lotion for workers to apply to their skin which would increase their protection when the additive may already have been used in the brine itself. Such cream or lotion may be - u recommended for workers who may be overly sensitive to the effect of brine. Additionally, such a cream or lotion or other liquid could, it is envisaged, be used to protect the outerwear of workers, particularly leather wearing apparel which is subject to severe attack by brine.
  • the additive of the present invention could be provided in a spray form which could be in individual containers for use by workers or perhaps could be used as a body spray in a shower unit.
  • the additive of the present invention could be used in a cleanser used for cleaning any skins which may have been exposed to brine.
  • brines may have substantially different formulations and be of substantially different strengths
  • the additive of the present invention may have a specific formulation which may be specifically adapted for use with a particular brine.
  • the additive is required to have high water solubility so that even in a super-saturated heavy brine, the additive may be accepted.
  • Glycoaminoglycans (and Hydrolised); Saiclic acid and derivatives; Cucumber extract; and Witch Hazel extract.
  • ingredients may have some action in more than one category, e.g. some of the polymers will also be surfactants and some of the oils may be polymeric in nature.
