Patent application number | Description | Published |
20080306144 | Hydroxybenzyl or hydroxypyranonemethyl esters as tyrosinase inhibitors - Method for the preparation of ester compounds for use as skin brightening agents and compositions for brightening skin containing the ester compounds. | 12-11-2008 |
20090042271 | Esters of long-chain alcohols and preparation thereof - Disclosed are esters and a process for the preparation of the esters represented by formula 1: | 02-12-2009 |
20090203779 | ESTERS OF LONG-CHAIN ALCOHOLS AND PREPARATION THEREOF - Disclosed is a composition and methods of treating a skin condition. The ester includes an ester and a dermatologically acceptable carrier. The ester is represented by the general formula 1: | 08-13-2009 |
20100076077 | ESTERS OF 4,5-DISUBSTITUTED-OXY-2-METHYL-3,6-DIOXO-CYCLOHEXA-1,4-DIENYL ALKYL ACIDS AND PREPARATION THEREOF - Esters of 4,5-disubstituted-oxy-2-methyl-3,6-dioxo-cyclohexa-1,4-dienyl alkyl acids were prepared chemically and/or enzymatically. Depending upon the ester, improved melanocyte cytotoxicity was achieved. Improved cytotoxicity characteristics are consistent with ester analogs being more physiologically compatible and less irritating to skin than their corresponding acids. | 03-25-2010 |
20110129430 | HYDROXYBENZYL OR HYDROXYPYRANONEMETHYL ESTERS AS TYROSINASE INHIBITORS - Method for the preparation of ester compounds for use as skin brightening agents and compositions for brightening skin containing the ester compounds. | 06-02-2011 |
20120029198 | ESTERS OF O-SUBSTITUTED HYDROXY CARBOXYLIC ACIDS AND PREPARATIONS THEREOF - Esters of O-substituted hydroxy carboxylic acids are provided having Formula 1, or 2, or both Formulas 1 and 2: | 02-02-2012 |
20120059056 | CARBONATE DERIVATIVES AS SKIN CARE - Carbonates of anti-aging ingredients, in particular anti-oxidants and skin illuminating phenol ingredients, have been prepared as derivatives of these ingredients with enhanced physical properties. It has been demonstrated that these carbonates will hydrolyze under enzymatic catalysis to release the parent ingredient. In contrast, esters of the phenolic groups in many cases do not hydrolyze under the same conditions. | 03-08-2012 |
20120215024 | HYDROXYALKANOIC ACID AND HYDROXYALKANOICE ACID OLIGOMER ESTERS OF RETINOL - Retinyl hydroxyesters and retinyl oligo-hydroxyesters were prepared using a chemoenzymatic process from retinol and short chain esters of hydroxycarboxylic acids or short chain esters of hydroxycarboxylic acids. The presence of the hydroxyl group on the acid can result in a mixture of esters from various oligomers of the hydroxycarboxylic acid. The retinyl ester products are readily enzymatically hydrolyzed in vitro, which indicates that application to the skin should result in release of the anti-aging ingredient retinol (without the inherent instability and irritation) along with the acid, which, if chosen appropriately, should also have desirable biological effects. This combination should be effective as an anti-aging skin care ingredient. | 08-23-2012 |
20120277324 | BETAINE ESTERS AND PROCESS FOR MAKING AND USING - A variety of betaine esters, including dial kylaminoalkyl cocoate betaines. These betaines were advantageously prepared in high yield and purity by a three-step chemoenzymatic process. These betaine esters have excellent surfactant properties. | 11-01-2012 |
20120302638 | ESTERS OF 4,5-DISUBSTITUTED-OXY-2-METHYL-3,6-DIOXO-CYCLOHEXA-1,4-DIENYL ALKYL ACIDS AND PREPARATION THEREOF - Esters of 4,5-disubstituted-oxy-2-methyl-3,6-dioxo-cyclohexa-1,4-dienyl alkyl acids were prepared chemically and/or enzymatically. Depending upon the ester, improved melanocyte cytotoxicity was achieved. Improved cytotoxicity characteristics are consistent with ester analogs being more physiologically compatible and less irritating to skin than their corresponding acids. | 11-29-2012 |
20130177951 | CHEMO-ENZYMATIC PROCESS FOR PREPARING QUATERNARY AMMONIUM ESTERS - A process for producing surface-active quaternary ammonium esters is provided. These esters are advantageously prepared in high yield and purity by a chemo-enzymatic process. These compounds have excellent surfactant properties. | 07-11-2013 |
20130273183 | 2-Pyrimidine Thioesters and Thiocarbonates as Skin Brightening Agents - 2-Pyrimidine thioesters and thiocarbonates are disclosed as effective skin brightening agents. These compounds may be formulated with dermatologically acceptable carriers to form skin brightening compositions. Methods for brightening skin and for inhibiting melanogenesis using these agents are also disclosed. | 10-17-2013 |
20140050687 | BETAINE ESTERS AND PROCESS FOR MAKING AND USING - A variety of betaine esters, including dialkylaminoalkyl cocoate betaines and dialkylaminoalkyl hydrogenated cocoate betaines are disclosed. These betaines can be advantageously prepared in high yield and purity by a three-step transiterification chemoenzymatic process or a two-step direct esterficiation chemoenzymatic process. These betaine esters have excellent surfactant properties. | 02-20-2014 |
20150025247 | ESTERS OF O-SUBSTITUTED HYDROXY CARBOXYLIC ACIDS AND PREPARATIONS THEREOF - Esters of O-substituted hydroxy carboxylic acids are provided having Formula 1, or 2, or both Formulas 1 and 2: | 01-22-2015 |
