Filed:

Jun 29, 1988

Appl. No.:

7/212778

Inventors:

Walter F. Voyt - Joliet IL

Assignee:

Amoco Corporation - Chicago IL

International Classification:

C02F 330

US Classification:

210605

Abstract:

Methods for controlling sludge bulking in aerobic waste treatment processes are presented in which nitrogen metabolism is controlled and a steady seed of facultative nonfilamentous bacteria is provided to an aerobic waste treatment process.

US Patent:

49752723, Dec 4, 1990

Filed:

Mar 18, 1987

Appl. No.:

7/027416

Inventors:

Walter F. Voyt - Joliet IL

International Classification:

A61K 740
A61K 742
A61K 744
A61K 748

US Classification:

424 59

Abstract:

A method of and composition for the prevention of solar radiation absorption-induced formation of carcinogenic skin lipid degradation products, particularly malonaldehyde, consisting of the application, prior to exposure of the skin to natural or artificial sources of solar radiation, of a composition comprising an ultraviolet screen--effective amount of an ultraviolet absorbing compound selected from the group consisting of a salicylate, a para-aminobenzoate, an alkyl ester of para-dialkylaminobenzoic acid, a benzophenone, a cinnamate, a napthoate, an acid-esterified gallate and mixtures thereof; at least one non-hindered, non-acid esterified, oil soluble, phenolic substituent-bearing latent oxidation inhibitor compound, such as the tocopherols, alcoholic esters of gallic acid, nordihydroguaiaretic acid, and mixtures thereof, the total concentration of said inhibitor present constituting a pro-oxidant-effective amount sufficient to demonstrate pro-oxidant properties, said inhibitor concentration further being insufficient to constitute an ultraviolet screen-effective amount demonstrating ultraviolet screening properties; and an inert carrier vehicle for said compounds comprising an oil soluble component, the vehicle being non-toxic and non-irritating to the skin. Utilization of an oil soluble ultraviolet absorbing compound obviates the necessity for a separate oil soluble component-containing carrier vehicle.

Appl. No.:

5/740646

Inventors:

Walter F. Voyt - Elwood IL

International Classification:

A61K 742
A61K 744
A61K 31355

US Classification:

424 59

Abstract:

A method of and composition for preventing erythema of the skin caused by the absorption of burning ultraviolet radiation resulting from exposure to natural or artificial sources thereof while concomitantly allowing tanning of the skin is provided, consisting of the application of a sunscreen composition demonstrating selective ultraviolet radiation absorption in the 295-315 nanometer wavelength range prior to exposure of the skin to said radiation source, said composition comprising a sunscreen-effective amount of an ultraviolet-absorbing tocopherol compound selected from the group consisting of alpha tocopherol, beta tocopherol, gamma tocopherol, delta tocopherol, epsilon tocopherol, zeta tocopherol, eta tocopherol and mixtures thereof, and an inert carrier vehicle, said vehicle being non-toxic and non-irritating to the skin.
