  • the self-foaming cleansing compositions include a surfactant, a humectant, a nourishing agent, and a chelator.
  • Personal cleansing compositions are popular for their ability to remove dirt, oil and debris from the skin or hair of the consumer.
  • Typical surfactant-based cleansers are formulated to provide a specific cleansing power, feel, mildness and lather volume. Each criterion is significant in the desirability of the cleansing product. For example, lather volume is significant as one factor in determining the efficacy and reach of the product.
  • personal cleansers should gently cleanse the skin or hair of the user without causing undesirable irritation or leaving the skin dry.
  • Other ingredients may be added to the surfactant-based composition to aid in the cleansing process.

  • the pH adjusters can comprise the alpha-hydroxy acids of citric acid, glycolic acid, lactic acid, malic acid, tartaric acid, or a combination thereof.
  • the pH values can be assessed with commercial instrumentation such as a pH meter made commercially available from Thermo Scientific®.
  • the pH adjusters can be present in an amount of 0.1 to 1.0% by weight of the total weight of the self-foaming cleansing composition, for example, 0.25 to 0.75% by weight, for example, 0.5 to 0.6% by weight of the total weight of the concentrated conditioning composition, including any and all ranges and values subsumed therein.
  • Preservatives can desirably be incorporated into the self-foaming cleansing composition to protect against the growth of potentially harmful microorganisms.
  • Preservatives are antimicrobial ingredients added to maintain the microbiological safety of products. They act to inhibit the growth of microbes and so reduce the level of microbial contamination. As personal wash formulations such as those disclosed herein contain biodegradable ingredients, they can become unpleasant and unsafe if microbial breakdowns is not controlled. Microbial growth is water dependent, so preservatives must partition to some extent into the aqueous phase of a formulation. Commonly used preservatives can be categorized into the following five classes:
  • Parabens such as Methyl-, Propyl-, and Butylparaben and Germaben II are derived from parahydroxy benzoic acid. These materials are economical and effective against fungals and some Gram negative bacteria but need a second ingredient to control Gram positives. They also tend to partition more towards the oil phase in emulsion-containing formulations. They are widely employed at levels of 0.01-0.3% by weight and are generally considered safe - though there have been concerns over possible estrogenic activity and links to cancer.
  • Formaldehyde Releasers such as Germall Plus, DMDM Hydantoin, and Imadozolidinyl or Diazolidinyl Urea. This class of materials is effective against bacteria but offers only weak antifungal activity. They are used at levels of 0.1 -0.5% by weight in the pH range 3-8. The low levels of free formaldehyde released ensure microbial inhibition, but cause concerns as potential carcinogens.
  • Isothiazolinones such as methylcholoroisothiazolinone (MCI), methylisothiazolinone (Ml), and Kathon. Isothiazolinones offer broad spectrum effectiveness over a broad pH range, but they may cause skin irritation for some consumers. This class of materials is employed at low levels, on the order of 10’s of ppms.
  • Phenoxyethanol marketed as Optiphen or Optiphen Plus and NeoIone PH 100. Phenoxyethanol is often considered as a milder alternative to parabens or formaldehyde-donors but has a narrow spectrum of applicability to Gram negative bacteria.
  • caprylyl glycol sorbic acid/potassium sorbate, or EDTA to create broad spectrum efficacy. It is applicable over a wide range of pH, with a typical usage level of 1% or less. However, there are some concerns over possible carcinogenic activity.
  • Organic Acids such as Benzoic Acid/Sodium Benzoate, Sorbic Acid/Potassium Sorbate, Salicylic Acid/Sodium Salicylate, and Levulinic or Anisic Acids.
  • Organic Acids such as Benzoic Acid/Sodium Benzoate, Sorbic Acid/Potassium Sorbate, Salicylic Acid/Sodium Salicylate, and Levulinic or Anisic Acids.
  • the use of these acids is confined to aqueous applications in the pH range 2-6. They typically are used at higher levels than some of the above alternatives and have somewhat weaker efficiency against bacteria (which can be augmented by combination with diazolidinyl urea), though they are very good against fungi. This class of preservatives are generally considered as natural.
  • Preservatives for use in the cleansing compositions disclosed herein preferably include organic- acid based preservatives, preferably sodium benzoate, caprylyl glycol, or a combination thereof.
  • Traditional preservatives for use include hydantoin derivatives and propionate salts.

  • Other preservatives include sodium benzoate, sodium dehydroacetate, chlorophenesin, decylene glycol, methylchloroisothiazolinone, methylisothiazolinone, or a combination thereof.
  • the preservatives should be selected having regard for the use of the composition and possible incompatibilities between the preservatives and other ingredients in the cleansing composition. Also preferred is a preservative system with hydroxyacetophenone alone or in a mixture with other preservatives. Particularly preferred is sodium benzoate.
