  • Publication number: 20130298338
    Abstract: A skin conditioning program comprises a skin softening and repair step where a natural composition is applied to the skin; a hair extraction and follicle decongestion step where a natural composition is applied to the skin; a follicle detoxification step where a mineral composition is applied to the skin; and skin exfoliation step where a mineral composition is applied to the skin. These program elements are complementary. The skin softening and repair improves the exfoliation; improved exfoliation improves the penetration and efficiency of the follicle detoxification; and the improved detoxification improves paste penetration and sugaring efficiency. The skin conditioning program is designed to establish and to maintain improved skin and hair follicle condition in order to promote more effective hair removal.

  • Patent number: 7465321
    Abstract: Film, fibre, foam and adhesive materials are produced from soluble S-sulfonated keratins. Once formed, the films, fibres, foams or adhesives are treated to modify the properties of the materials, in particular to improve the wet strength of the materials. Treatments used include removal of the S-sulfonate group by treatment with a reducing agent, treatment with an acid or treatment with a common protein crosslinking agent or treatment with a reduced form of keratin or keratin protein. The films are made by solvent casting a solution of S-sulfonated keratin proteins, the foam made by freeze-drying a solution of S-sulfonated keratin proteins and the fibres made by extruding a solution of a S-sulfonated keratin protein.

  • Patent number: 6589293
    Abstract: The invention relates to the dehairing (depilating) of animal pelts, hides or skins, more specifically to depilatory paint and depilatory paint (depilation paint) thickener used in the depilation process in for example fellmongeries. The invention provides a depilatory paint thickener comprising a starch containing essentially only amylopectin molecules. Such thickener, is among other things, easily soluble in cold water; improves diffusion of chemicals (like sulfide or lime) throughout the skin; improves viscosity or resistance to shear of a paint, whereby less starch is needed to exert a similar effect; and increases the suspendability of a lime, allowing less time to be used which creates environmental advantages in waste disposal.

  • 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.

  • Patent number: 4842610
    Abstract: Hair removal compositions useful for cosmetic, medical and other purposes comprise 90 to 99.5% corn syrup and 0.5% to 10% added water by weight. The compositions can also include additives such as germicides, preservatives and opacifiers. The compositions are used by applying them to the surface of the skin in a hairy area, pressing a sheet of paper or other fibrous material against the area and subsequently lifting the sheet of fibrous material or peeling it off the skin surface. The compositions are also useful in removing blemishes and scaly, flaky or dry skin.

  • Patent number: 4832949
    Abstract: A depliatory composition for removal of hair from the human skin is made up of a mixture of honey, sugar and citric acid which mixture is heated to a predetermined temperature level, then allowed to cool so as to form a highly viscous, wax-like composition which can be applied manually in slender strips to the skin. The composition will firmly adhere to the hair with which it comes into contact and, by quickly drawing away from the skin, will cause the hair to be removed from its root but without causing undue irritation and swelling.

  • Patent number: 4156067
    Abstract: Polyurethane polymers characterized by a molecular weight above 6,000 and having lactone groups and hydroxyl groups in the polymer backbone are prepared by reacting a mixture of polyols, a polyfunctional lactone and a polyfunctional isocyanate proportioned so as to provide the desired polymer properties. The product is soluble in alkaline solutions and may be used for light sensitive photographic layers on films, paper or glass; in drug delivery systems, as burn dressings, in body implants such as vascular prosthesis, in molding compositions, and in the manufacture of catheters. The novel polymers also find use in the manufacture of artificial finger nails, finger cots, adhesives, and in protective and hdyrostatic drag resistant coatings. The water absorptivity of the polyurethane lactone polymers is above 10%, preferably in the range of about 20% to 60%, and these polymers may range in their physical properties from rigid solids to completely gel-like high water absorptive polymers.
