  • Patent number: 7238343
    Abstract: Hair removal, especially from armpits damages skin, for example by irritating it, and this can be exacerbated by the application of antiperspirants to control body odour generation. In the present invention, the deleterious effects of hair removal, eg shaving, and antiperspirancy can be ameliorated by employing antiperspirant compositions containing a natural oil and glycerol to a combined concentration of from 1.5 to 15% by weight and in a weight ratio of from 4:1 to 1:4.

  • Patent number: 7153495
    Abstract: A cost effective process is provided for making stable, efficacious, amino acid and polyhydric alcohol free concentrated aqueous aluminum zirconium salt solutions. Absence of amino acid, low iron content and low trace metal impurity levels improve compatibility with fragrances and minimizes the probability of the product color change and possibly fabric staining significantly. The novel aluminum zirconium actives also minimize iron contribution to underarm area that supports growth of microflora which is responsible for axillary malodour by the biotransformation of nonodorous precursors present in perspiration. The astringent complexes of the present invention may be obtained in solution or dry powder form. As a result, the complexes are satisfactory for use in any of wide variety of conventional antiperspirant forms.

    Abstract: A novel efficacious and less irritant aluminum-zirconium antiperspirant composition is provided by the addition of a small amount of AlCl3 and/or HCl to the activated aluminum component. After the heating of diluted basic aluminum chlorohydrate solution, cooling to room temperature, mixing with small amount of AlCl3 or HCl and then reacting with zirconium glycine complex, an aluminum-zirconium salt is produced with a maximum amount of depolymerization aluminum and zirconium species. The addition of a small amount of AlCl3 or HCl to the diluted and activated aluminum chlorohydrate solution accelerates the depolymerization of the activated ACH solution, and upon the addition of zirconium glycinate the solution is further depolymerized and results in the formation of less polymerized zirconium species.

  • Patent number: 6835374
    Abstract: Antiperspirant actives that produce practically no visible white residue, even against a black background is provided by the reduction of the particle size, using a refractive index modifier, to a point where the antiperspirant active on application provides no discernible whiteness. When formulated into an antiperspirant stick, the antiperspirant actives produce an improved combination of functional properties, including excellent antiperspirancy, smooth skin feel, nontacky, quick drying and leave no visible residue. The exceptionally high surface area of the antiperspirant active results in rapid and efficient delivery of the active to the sweat glands and possible absorption. The absence or reduced quantity of suspending and flow enhancing agents, of gellant and surfactant, is believed to improve the antiperspirant active's ability to physically reach the sweat glands and improve efficacy.
