Abstract Skin moisturizing is important in dermatology and cosmetics. Raman microspectroscopy a well‐suited method to determine water concentration profiles the stratum corneum (SC) of untreated formulation‐treated skin vivo. Until now, SC was quantified using ratio proteins, other components were neglected. Here, we apply tailored multivariate curve resolution‐alternating least squares (tMCR‐A...

Acne is a cutaneous pleomorphic disorder of the pilosebaceous unit involving abnormalities in sebum production and is characterized by both inflammatory (papules, pustules and nodules) and no inflammatory (comedones, open and closed) lesions. Propionibacterium acnes and Staphylococcus epidermidis are common pus-forming microbes responsible for the development of various forms of, acne vulgaris....

The potential of arid/semiarid land plants a s sources of commercial products is illustrated by the following examples: candelilla (wax); jojoba (oil, protein); Acacia spp. (gum); Astragalus spp. (tragacanth gum); guayule (rubber); rabbitbrush (rubber, chemicals); sunflowers (rubber, chemicals); yucca (soap); and cresote bush (antioxidants, phenolic resins). co-evolutionary selection is a cause...

The C10-C18 unsaturated, acyclic, aliphatic compounds that contain an oxygenated functional group (alcohol, aldehyde, or acetate ester) are a major class of sex pheromones produced by female moths. In the biosynthesis of these pheromone components, the key enzyme required to produce the oxygenated functional groups is fatty-acyl reductase (FAR). This enzyme converts fatty-acyl pheromone precurs...

Field ionization (FI) and field desorption (FD) mass spectra of 35 aliphatic long-chain and branched long-chain compounds, representing the m ajor six classes of constituents of natural waxes, are examined. In the FI mode the molecular ions are usually formed at comparatively low levels, while in FD such species are almost exclusively generated. In addition, some fast atom bom bardm ent mass sp...
