molecules with novel skeletons, but also to identify the enzymes that catalyze diverse chemical reactions. Exploring the substrate promiscuity and catalytic mechanism of those biosynthetic enzymes facilitates the development of potential biocatalysts. SfaB is an acyladenylate‐forming enzyme that adenylates a unique building block, 3‐isocyanobutanoic acid, in the biosynthetic pathway of the diisonitrile
The present invention provides a cosmetic composition containing (A) a powder composed of one or more kinds of the N-medium-chain-acyl basic amino acid powder represented by the following formula (I), (B) an inorganic powder, and (C) an oil material:
wherein R is a saturated or unsaturated straight hydrocarbon group having 5-9 carbon atoms, and m is an integer of 1-4.
The present invention aims to provide a medium-chain acyl basic amino acid derivative which, when blended in a liquid 5 cosmetic such as skin lotion, skin milk and the like, suppresses gelation while maintaining affinity to the skin and the like and can afford a stable preparation.
The present invention relates to a compound represented by the formula (1)
wherein each symbol is as described in the DESCRIPTION, or a salt thereof.
The present invention provides a composition containing component (A): a compound represented by the formula (1)
wherein each symbol is as described in the DESCRIPTION, or a salt thereof, and component (B): an anionic water-soluble m polymer, which suppresses syneresis and aggregation over time, is superior in the maintenance of viscosity in a wide pH range even in the presence of electrolyte or alcohol, and suppresses stickiness and sliminess.
The present invention provides a composition containing component (A): a compound represented by the formula (1)
wherein each symbol is as described in the DESCRIPTION or a salt thereof, component (B): a water-soluble moisturizing component and component (C): water, as a stable composition which is superior in affinity and adhesion to the skin and hair, easily provides effects as a cosmetic, and is also superior in the sustainability of the effect.
