The catalytic pyrolysis of glucose over amphoteric metal oxide, ZnO or γ-Al2O3, was studied comparatively with direct pyrolysis. The effects of catalyst to glucose ratio on the yields of pyrolytic products and on the chemical composition of the liquid products were discussed. Compared with the ...
other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all instances by the term “about”. The present invention relates to a cosmetic system and process suitable for...
The surfactants present in the first part-composition and optionally the second part-compositions include in particular, anionic surfactants and nonionic surfactants, although cationic surfactants and amphoteric surfactants may also be useful. The anionic surfactants used are preferably one or more ...

Examples of hydrophilic organic solvents that may be included in the sunscreen compositions include: monohydric C1-C8 alcohols such as ethanol, propanol, butanol, isopropanol, isobutanol; Polyethylene glycols from 6 to 80 ethylene oxides such as propylene glycol, isoprene glycol, butylene glycol, ...
In this case, the surfactant(s) are chosen from nonionic, cationic, anionic and amphoteric surfactants and preferably from nonionic and anionic surfactants. However, according to one particular embodiment, emulsion (A) does not contain any nonionic surfactants other than that or those with an HLB ...
Preferably, said process comprises the CMP of a metal-containing substrate, that is a substrate comprising metal in the form of elements, alloys, or compounds such as metal nitrides or oxides. Said process comprises more preferably the CMP of a metal layer of said substrate, most preferably ...
A two-pack hair treatment composition comprising a first lotion containing a reducing substance (a) and a cationic polymer (b) and a second lotion containing an anionic surfactant or amphoteric surfac
The at least one coloring agent component may also comprise at least one adjuvant conventionally used in hair coloring compositions. For example, the at least one adjuvant may be chosen from anionic, cationic, nonionic, amphoteric and zwitterionic surfactants; anionic, cationic, nonionic, amphoteric ...
