Uses of topical compositions comprising a 2-hydroxycarboxylic acid or related compound to alleviate or improve signs of skin, nail and hair changes associated with intrinsic or extrinsic aging are disclosed. 2-Hydroxycarboxylic acids and their related compounds include, for example, 2-hydroxyethanoic acid, 2-hydroxypropanoic acid 2-methyl 2-hydroxypropanoic acid, 2-phenyl 2-hydroxyethanoic acid, 2-phenyl 2-methyl 2-hydroxyethanoic acid, 2-phenyl 3-hydroxypropanoic acid, 2,2-diphenyl 2-hydroxyethanoic acid, 2-hydroxybutane-1,4-dioicacid, 2,3-hihydroxybutane-1,4-dioic acid, 2-carboxy 2-hydroxypentane-1,5-dioic acid, 2-ketopropanoic acid, methyl 2-ketopropanoate, ethyl 2-ketopropanoate, and gluconolactone. Topical application of compositions comprising 2-hydroxycarboxylic acid and/or related compounds has been found to alleviate or improve skin lines; blotches; blemishes; nodules; wrinkles; pigmented spots; atrophy; precancerous lesions; elastotic changes characterized by leathery, coarse, rough, dry and yellowish skin; and other skin changes associated with intrinsic aging or skin damages caused by extrinsic factors such as sunlight, radiations, air pollution, wind, cold, dampness, heat, chemicals, smoke and cigarette smoking. Topical applications of such compositions have also been found to improve the overall qualities of nail and hair affected by intrinsic aging or damaged by extrinsic factors.

Alleviating signs of dermatological aging with glycolic acid, lactic acid or citric acid

Methods and compositions are disclosed for delivering lutein or other antioxidant to target tissues such as the eye, in bioactive form, while protecting the antioxidant from degradation. The antioxidant is encapsulated in nanoparticles comprising a protein such as zein or a polymer such as poly(lactic-co-glycolic acid) (PLGA). Preferably a surfactant is associated with the nanoparticles as well, further helping to protect the antioxidant. After the nanoparticles are administered to the target tissue, bioactive antioxidant is released to the tissue over time. Optionally, the nanoparticles are admixed with a thermosensitive, bioadhesive gel to promote slow release of antioxidant. The methods and compositions are useful for treating or preventing conditions such as age-related macular degeneration or cataracts.

Delivery of bioactive, nanoencapsulated antioxidants

An object of the present invention is to provide an emulsification-stable pesticidal composition having ant-control, rotcontrol and mildew-control effects. Another object of the present invention is to provide a composition having pesticidal effects, and particularly antimicrobial effects, for protecting industrial materials such as wood, pulp, paper, fibers, adhesives, films subject to deterioration (rotting) and contamination by insects and particularly by microorganisms. A pesticidal composition is used that comprises an emulsification stabilizer selected from the group consisting of lactic acid, glycolic acid, citric acid, succinic acid, benzoic acid and a mixture thereof, a fungicide like 2-(thiazol-4ine)benzimidazole; a further triazole-based fungicide component, a pyrethroid insecticide component or a (thia) nicotinyl insecticide or another insecticide component, a mixed solvent comprising a glycol-based solvent and methyl pyrrolidone, and a surfactant.
