  • Patent number: 5463098
    Abstract: A residue free, antiperspirant gel stick composition is disclosed which comprises an antiperspirant compound which is soluble in a diol, a normally liquid, water soluble diol, a gelling agent and a zinc glycinate in amount sufficient to control the pH of the gel stick at about 4.1 to about 5.0, the glycine to zinc mole ratio of the zinc glycinate added being about 2.0/1 to about 3.0/1. The process for preparing a diol soluble antiperspirant active useful in preparing the residue free gel stick is also disclosed and comprises reacting an antiperspirant compound with a water soluble, normally liquid diol in a water solution by heating for about 1 to about 100 hours at a temperature of about 50.degree. C. to about 110.degree. C.; adding a zinc glycinate to the reaction mixture and removing the water to recover a powdered antiperspirant active.

  • Patent number: 5453267
    Abstract: The invention relates to titanium dioxide sunscreen compositions containing 0.025 to 30% by weight of phosphate anions. Phosphate anions, preferably in the form of salts, have been found to prevent or reduce the rate of discolouration of titanium dioxide-containing sunscreen compositions caused by light catalysed reduction of titanium (IV) to titanium (III). Discolouration caused by the presence of parahydroxybenzoic acid esters or para-aminobenzoic acids, esters or derivatives thereof in such compositions has also been found to be reduced by the incorporation of phosphate salt.Titanium dioxide particles having a mean primary particle size of less than 100 nm, each of the particles being substantially coated with phosphate anions are also described for use in sunscreen compositions.
