(EN) SUNLESS TANNING COMPOSITION AND METHODS FOR USING
(FR) PREPARATION AUTOBRONZANTE ET METHODES D'APPLICATION
Abstract
(EN) A sunless tanning composition is provided according to the invention. The sunless tanning composition includes an effective amount of a tanning active component to provide a darkening effect of skin tissue after exposure to the skin tissue, a polymer component, water, an effective amount of an acidifying agent to provide the composition with a pH of less than about 5, and wherein the composition has the viscosity of at least about 3,000 cSt. The polymer component can be characterized as a skin bonding polymer component to hold the tanning active component in exposure to the skin tissue when applied to the skin tissue. The polymer component can be characterized as a polymer having an average molecular weight of about 2,000 to about 500,000. A method of applying a sunless tanning composition to skin tissue is provided.
(FR) La présente invention décrit une préparation autobronzante. Ladite préparation autobronzante inclut une quantité active d'un composant autobronzant actif qui permet d'obtenir un effet bronzant sur la peau lorsque cette dernière est exposée audit composant autobronzant actif, un composant polymère, de l'eau, une quantité active d'un agent acidifiant conférant à la préparation un pH inférieur à environ 5, ladite préparation présentant une viscosité d'au moins environ 3000 cSt. Le composant polymère peut être caractérisé en ce qu’il présente des propriétés de liaison avec la peau, ceci afin de retenir le composant autobronzant actif en contact avec la peau lorsqu'il est appliqué sur la peau. Le composant polymère peut être caractérisé en ce qu'il s'agit d'un polymère de masse moléculaire moyenne comprise entre environ 2000 et environ 500 000. La présente invention décrit en outre une méthode d'application d'une préparation autobronzante.
