  • Oxidative hair dyes and related topical compositions
    Patent number: 7686849
    Abstract: An oxidative hair dye system comprises a hair dye, an organometallic compound and an oxidising agent. The organometallic compound is preferably an organotitanate compound, particularly a tetraalkyl titanate or a titanate chelate. Such compounds are also useful for enhancing the substantivity of topical compositions applied to the body, which comprise one or more cosmetic and/or therapeutic benefit agents, a bonding agent having hydrolysable or exchangeable ligands, and a carrier.
    Type: Grant
    Filed: April 6, 2006
    Date of Patent: March 30, 2010
    Assignee: The Boots Company PLC.
    Inventors: Neil Robert Forbes, Edward Galley, Christine Sheard

  • Nail lacquers
    Patent number: 5330750
    Abstract: A nail lacquer composition which comprises 0.05 to 10% by weight of crystalline inorganic fibers having an aspect ratio of at least 2:1 is described. Preferred inorganic fibers are calcium salts such as calcium metasilicate and calcium sulphate. The use of such fibers has been found to give nail lacquer compositions with excellent wear and adhesion properties.

  • Depilatory compositions
    Patent number: 4981682
    Abstract: A depilatory composition comprising a depilatory compound, in particular potassium thioglycolate, and a tertiary amine of general formula INR.sub.1 R.sub.2 R.sub.3 Iwherein R.sub.1 represents a long chain fatty moiety having 8 to 36 carbon atoms and R.sub.2 and R.sub.3 each independently represent a fatty moiety having 1 to 36 carbon atoms. The composition has pH of between 11.5 and 12.7. The softening effect of the tertiary amine avoids the growth of stiff stubble and does not reduce the efficacy of the depilatory compound.
