Bar Soap Provides UV Protection

U.S. Patent No. 7,700,079 B2; Jamie Collins Doss of Santa Fe, NM has patented a soap bar that provides UV protection through normal washing and rinsing. It contains a natural soap base for cleaning the skin; titanium dioxide and zinc oxide for providing protection against UV rays, wherein said zinc oxide and titanium dioxide are in 2:1 ratio and are in ultrafine or microfine form; chlorophyll for promoting wound healing, detoxifying, deodorizing, and inhibiting bacterial growth; lemon juice for providing a mild exfoliant; healing balm of Gilead; aloe vera; one or more vitamins selected from the group consisting of A, C, D, L, K, B 1, B2, niacin, B6, B 12, folic acid and biotin; olive oil; one or more minerals selected from the group consisting of Ca, Fe, P, Mg, Zn, Se, and Cu; and amino acids. The balm of Gilead, chlorophyll, olive oil, aloe vera and lemon juice are present in ratio of 1:2:1:1:3 proportions, respectively.

Hockmeyer Earns 5th Patent On Immersion Milling

U.S. Patent No. 7,559,493; Hockmeyer Equipment has received its fifth patent covering immersion mill enhancement. The patent covers the deterrence of wear at a bearing construct in a basket media mill. The device involves the introduction of slots in the rotating peg hub within the basket, according to Hockmeyer.

As the hub rotates, centrifugal force pulls the media and feedstock away from the polymer-bearing construct within the peg hub. This results in two favorable conditions; extended bearing life regardless of the media type or size; elimination of micro media escaping through the clearance between the rotating drive shaft and the bearing construct. Bearing life (typically 6 months to 1.5 years) has been more than doubled. Micro media (typically smaller than .3mm) is no longer a containment problem. The centrifugal hub prevents micro media from escaping through the polymer-bearing construct and the auger in the upper feed tube into the mill prevents media from floating out as the mill is immersed into the feedstock.

The addition of this feature to existing Hockmeyer mill patents enhances their utility by allowing the use of micro media to disperse particles into the low nanometer range (120 nanometers and below) in a fraction of the time required for conventional horizontal milling technology, according to the company.

Hard Surface Cleaner Patented By Clorox

U.S. Patent No. 7,700,540 B2; The Clorox Company has patented an aqueous cleaning composition for hard surfaces. It contains a water-soluble or water-dispersible copolymer having a first monomer that is capable of forming a cationic charge on protonation and a second monomer that is acidic and that is capable of forming an anionic charge in the compositions; a third monomer that has an uncharged hydrophilic group; and optionally, a fourth monomer that is hydrophobic. It also contains an organic solvent, a surfactant and an adjuvant. The mole ratio of the first monomer to the second monomer ranges from 19:1 to 4:1 or from 1:4 to 1:10.

Coty Patents Water-Resistant Mascara

U.S. Patent No. 7,682,605 B2; Coty B.V., Haarlem, The Netherlands, has been awarded a U.S. patent for a waterproof mascara composition.

The composition contains an oil phase comprising 0.1 to 30% by weight of an oil, 1-50% by weight of a silicon-based film-forming agent, and 0.1-10% by weight of a gel-forming agent being a mixture of glyceryl behenate and stearyl behenate in a ratio of 1:2 to 1:4; 7-15% by weight of pigments, powders with pigment like effects, or mixtures thereof; a water phase; 0.1-10% by weight of a surface active agent; and further carrier substances, auxiliaries, active agents or mixtures thereof.

According to the patent literature, the composition is free of waxes and hydrocarbon solvents. The applied water-proof mascara composition exhibits no statistically increased amount of streaking, smudging or flaking after immersion in water.

LVMH Patents Cosmetic With Skin Tightening Effect

U.S. Patent No. 7,700,084 B2; LVMH Recherche, Paris, has patented a composition that has a skin-tightening effect.

It is made of a polysaccharide having a molecular weight of less than 600,000 Daltons, sorbitol, poly (vinyl alcohol) or polyvinylpyrrolidone, and cellulose or of a derivative of cellulose.

Colgate Patents Foaming Hard Surface Cleanser

U.S. Patent No. 7,700,536 B2; Colgate-Palmolive Co. has patented a foamable composition that contains triethanolamine lauryl sulfate; propylene glycol n-butyl ether; ethanol; a dispersant; and water. The composition has an improved run down time, according to the patent literature.

Galderma Patent Foaming Hair Care Treatment

U.S. Patent No. 7,700,081 B2; Galderma S.A., Cham, Switzerland, has been awarded a U.S. patent for a foaming hair care composition that treats ailments of the scalp.

It is comprised of clobetasol propionate, sodium lauryl ether sulphate, cocoyl betaine, polyquaternium 10, ethanol (95-96%), citric acid and sodium citrate in an amount required to adjust the pH of the composition and water.

The treatment is to be left in for 2.5-15 minutes and then rinsed with water.
