Definitions

  • ANTIPERSPIRANT COSMETIC COMPOSITIONS USE OF THE ANTIPERSPIRANT COSMETIC COMPOSITION, AND PROCESS FOR MANUFACTURING AN ANTIPERPIRANT COSMETIC COMPOSITION
  • the present invention is directed to an antiperspirant cosmetic composition which combines exfoliant peeling agents, emollients, and aluminum salts to achieve a stable antiperspirant cosmetic composition that provides sweat and unpleasant odor protection. Additionally, the present invention is directed to the use of an antiperspirant cosmetic composition and process for manufacturing an antiperspirant cosmetic composition.
  • Sweating though a natural bodily function, results in the formation of wet patches on human skin and/or clothing. Moreover, the sweat secreted from sweat glands has a tendency to form a malodorous due to its interaction with the many microorganisms which reside on the skin surface, particularly the skin of the underarm. These two phenomena are deemed to be undesirable for consumers.
  • Antiperspirant products possess ingredients which inhibit/suppress sweating, whereas deodorant products possess ingredients that mask the malodors caused by sweat. Many products address both phenomena simultaneously.
  • Antiperspirant active agents generally consist of salts or complexes of aluminum and/or zirconium, such as aluminum chloride and aluminum hydroxy halides. These substances help to reduce the flow of sweat.
  • antiperspirant products are available in the market, such as powders, liquids, gels, emulsions, soft solids and sticks.
  • antiperspirant active agents To achieve a satisfactory antiperspirant effect, it is needed to use high concentrations of antiperspirant active agents. Such high concentration of antiperspirant active agents affects the stabilization of the cosmetic composition in view of the interaction with the other ingredients, as well as can cause irritation to the skin.
  • Such stabilization of antiperspirant cosmetic composition is also impacted when the composition comprises exfoliant peeling agents such as salicylic acid derivatives.
  • exfoliant peeling agents such as salicylic acid derivatives.
  • Such compounds occur in crystalline form and are not soluble in water or in oils traditionally used in the cosmetic field. Consequently, they tend to remain crystalline within various compositions, which significantly reduces the bioavailability of the compound and the cosmetic composition.
  • the presence of crystalline salicylic acid derivatives provides formulations which are unstable due, for example, to settling, and which are unpleasant regarding texture and appearance from consumer’s viewpoint.
  • Document CA2138110 discloses to solubilization of salicylic acid derivatives in vegetable oils, like flowers and fruit oils, using a process that involves the rising of temperature to achieve the solubilization.
  • those oils are complex mixtures of many different classes of compounds, and it may impact on the stability and the cost of formulas.
