2-Ethylhexyl salicylate also known as octisalate or octyl salicylate, is an organic compound used as an ingredient in sunscreens and cosmetics to absorb UVB (ultraviolet) rays from the sun. [1] It is an ester formed by the condensation of salicylic acid with 2-ethylhexanol. It is a colorless oily liquid with a slight floral odor.
Octyl Salicylate (INCI Ethylhexyl Salicylate) [23] Complexing avobenzone with cyclodextrins may also increase its photostability. [ 24 ] Formulations of avobenzone with hydroxypropyl-beta-cyclodextrin have shown significant reduction in photo-induced degradation, as well as decreased transdermal penetration of the UV absorber when used in high ...
Interactive Forms is a mechanism to add forms to the PDF file format. PDF currently supports two different methods for integrating data and PDF forms. Both formats today coexist in the PDF specification: [38] [53] [54] [55] AcroForms (also known as Acrobat forms), introduced in the PDF 1.2 format specification and included in all later PDF ...
The free acid is an odorless, white to off-white crystalline substance. [citation needed] Naproxen free base is lipid-soluble and practically insoluble in water, while naproxen sodium and many other salts are freely soluble in water, often soluble in methanol, and sparingly soluble in alcohol; check the specific solubility of each salt before use.
The ferric chloride test is used to determine the presence of phenols in a given sample or compound (for instance natural phenols in a plant extract). Enols, hydroxamic acids, oximes, and sulfinic acids give positive results as well. [1]
More specifically, optimal levels are generally close to a central tendency of the values found in the population. However, usual and optimal levels may differ substantially, most notably among vitamins and blood lipids, so these tables give limits on both standard and optimal (or target) ranges.
Maximum contaminant levels (MCLs) are standards that are set by the United States Environmental Protection Agency (EPA) for drinking water quality. [ 1 ] [ 2 ] An MCL is the legal threshold limit on the amount of a substance that is allowed in public water systems under the Safe Drinking Water Act (SDWA).
The cherimoya (Annona cherimola), also spelled chirimoya and called chirimuya by the Quechua people, is a species of edible fruit-bearing plant in the genus Annona, from the family Annonaceae, which includes the closely related sweetsop and soursop.
