General Description

Yellow liquid.

Air & Water Reactions

Contact with water or moist air generates toxic and flammable gases (amine and CO2).

Reactivity Profile

Isocyanates and thioisocyanates, such as 2,2,4-trimethylhexa-1,6-diyl diisocyanate , are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat. Acids and bases initiate polymerization reactions in these materials. Some isocyanates react with water to form amines and liberate carbon dioxide. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence, [Wischmeyer(1969)].

COSMETIC OR DERMATOLOGICAL COMPOSITION COMPRISING A POLYMER BEARING JUNCTION GROUPS, AND COSMETIC TREATMENT PROCESS

The present patent application relates to a cosmetic or dermatological composition comprising, in a cosmetically or dermatologically acceptable medium, a polymer comprising: (a) a polymer backbone that may be obtained by reaction: of a polyol comprising 3 to 6 hydroxyl groups;of a monocarboxylic acid containing 6 to 32 carbon atoms;of a polycarboxylic acid comprising at least two carboxylic groups COOH, and/or of a cyclic anhydride such as a polycarboxylic acid and/or of a lactone comprising at least one carboxylic group COOH; and(b) at least one junction group linked to the said polymer backbone and capable of establishing H bonds with one or more partner junction groups, each pairing of a junction group involving at least three H (hydrogen) bonds. The patent application also concerns a cosmetic treatment process using the said composition.

Preparation of biureto polyisocyanates

Clear, precipitate-free, storage-stable biureto polyisocyanates, well adopted for paint applications, are prepared by reacting at least one aliphatic, alicyclic or arylaliphatic monomeric diisocyanate with water, at a temperature of at least 70° C. and under an absolute pressure of at least 1.2 bar, including a partial pressure of carbon dioxide of at least 0.2 bar.
