Laundry StainPretreatment Sheet

• US Patent No. 7,973,003 B2; Dirty Laundry, LLC, Cleveland, OH, has patented a laundry stain and soil pretreatment sheet comprising a water soluble or water dispersible carrier layer, a removable separator layer and a layer of cleaning agent composition between said carrier layer and said separator layer. The cleaning agent composition is at least 50% (by weight)surfactant, and prior to use, the separator layer adheres to the composition layer by the stickiness of the composition layer. The separator layer is peelable and releasable from the composition layer prior to application of the sheet to a stained or soiled fabric.

Boston Cosmetics Patents Nanoscopic Hair Care Products

• US Patent No 7,968,084 BS; Boston Cosmetics LLC, Cambridge, MA, has patented a method of treating hair. It entails applying a hair treatment preparation to an individual’s hair. The preparation is comprised of liquid and a payload in an intimate relationship to a polymeric nano-structure, the polymeric nanostructure capable of being reactive to hair, or capable of being immobilized onto or in the hair; the polymeric nanostructure and the payload not being attached to the hair. Then applying an agent to the individual’s hair; the agent comprising at least one of a polymer and an ionic species, the agent interacting with the polymeric nanostructure such that the payload and nanostructure are attached to the hair under non-oxidizing conditions. The payload and nanostructure are not capable of detachment from the hair by water rinsing.

Shake-To-CleanCleaning Formula

• US Patent 7,956,024 B2; Gustavo M. Gonzalez, Pembroke Pines, FL, has been awarded a patent for a shake-to-clean composition that is a stable liquid-solid, two-phase cleaning composition including abrasive grains of inorganic salt in crystalline form suitable for removing organic deposits from interior surfaces of a substrate. The cleaning composition is comprised of a water miscible solvent; an inorganic salt selected from the group consisting of sodium chloride, sodium bromide, magnesium bromide, magnesium chloride, potassium chloride, potassium bromide and zinc chloride, and water. The inorganic salt is present in an amount of at least 20% of the total composition by weight, with at least some of the salt existing in crystalline form at 20°C, to about 70% of the total composition by weight in crystalline form at 20°C. The ratio of water miscible solvent:water is in the range of 9:1 to 2:1.

Kao Corp. PatentsTwo-Part Hair Dye

• US Patent No. 7,955,400 B2; Kao Corporation, Tokyo, has patented a two-part hair dye composition.

Hair Care Patents Awarded to L’Oréal

L’Oréal has been awarded a pair of patents related to its hair care business. In the first, US Patent No. US 7,972,387 B2, L’Oréal Paris, France, has been granted a patent for a composition that dyes keratin fibers. It is comprised of, in a suitable medium, at least one oxidation base, at least one coupler, and at least one polyoxyethylenated sorbitan ester. The polyoxyethylenated sorbitan ester is present in an amount ranging from 1% to 8% by weight relative to the total weight of the composition. The polyoxyethylenated sorbitan ester is chosen from sorbitan monolaurate oxyethylenated with 4 EO and sorbitan monostearate oxyethylenated with 4 EO.

In the second, US Patent No. 7,972,388 B2, L’Oréal S.A. has patented methods and kits to maintain the condition of colored hair.

The method is comprised of applying to the hair a pre-treatment composition comprising a humectant and at least one conditioning agent; combining a color-altering composition and a developer composition to form a mixture; applying the mixture onto the hair; removing the mixture from the hair; washing the hair with a shampoo composition; conditioning the hair with a conditioner composition; and applying a post-treatment composition onto the hair in order to inhibit color fading and/or impart both shine- and condition-enhancing properties. The post-treatment composition contains at least one conditioning agent and at least approximately 5% by weight of at least one oily component, based on the total weight of the post-treatment composition. The oily component is selected from the groups consisting of silicones, organic oils, synthetic oils and mixture thereof, according to the company.
