?-Gels are often used as base materials for cosmetics and hair conditioners. ?-Gel-based commercial products typically contain many types of additives, such polymers, electrolytes, oily components, other surfactants, in addition to the three basic components. However, few systematic studies have been conducted on effect additives ?-gels. In this study, we chose surfactant an example initiate st...

To prepare an herbal ointment using ethanolic extract of Berberis aristata and assess the anti-psoriatic effectiveness finished product. We were able to make multiple ointments that each categorized as F-1, F-2, F-3 by adding varying concentrations stearic acid cetyl alcohol learning about various formulation types, such oil in water. The analysis many factors, including pH, viscosity, spreadab...

Several methods (e.g., UV/H2O2 oxidation, adsorption, flocculation-precipitation) are normally employed to remove dye from water. A new technique based on liquid/liquid extraction using reverse micelles is proposed whereby recovery of solvent and reuse of dye is possible. Experiments were conducted by mixing a known quantity of dye in aqueous phase and solvent-containing surfactants in a simple...

BACKGROUND Waxes are esters of long-chain fatty acids and long-chain alcohols. Their principal natural sources are animals (sperm whale oil) and vegetables (jojoba) which are expensive and not easily available. Wax esters synthesized by enzymatic transesterification, using palm stearin as raw material, can be considered as an alternative to natural ones. RESULTS Palm stearin is a solid fracti...

The isolation of intact, high-molecular mass genomic DNA is essential for many molecular biology applications including PCR, endonuclease digestion, southern blot analysis, and genomic library construction. Many protocols are available for the extraction of genomic DNA from plant tissue, and all the protocols have used expensive and hazardous chemical-liquid nitrogen for grinding plant material...
