The present invention relates to a coalescing agent and a coating composition containing the coalescing agent as represented in structure (I); ##STR00001##
wherein; n is integer from 1 to 8; R.sup.1 and R.sup.2 independently represents group selected from alkyl, alkenyl, alkynyl, phenyl, or benzyl groups; and X represents group selected from hydroxy or amine. The coalescing agent according to this invention contains low amount of volatile organic compounds, has no pungent odour, and environmental friendly. Moreover, it provides good efficacy when being used as coating component.

A thermochromic pigment composition including compounds of formula (I):

##STR00001##

in which: X represents CHR.sub.2, O, OCO or CHCH; Y represents O, COO, or OCOO; R.sub.1 represents H or (CH.sub.2).sub.pCH.sub.3; R.sub.2 represents phenyl or H; m=12-18; n=0-14; p=12-18; and on the condition that, if n=0, X represents CHR.sub.2 or CHCH.

The thermochromic pigment compositions having compounds of formula (I), include thermochromic pigment microcapsules. The thermochromic pigment capsules are useable for thermochromic pigment compositions in ink which may be used writing instruments.

This invention relates to the field of contaminated plastic waste decomposition. More specifically, the invention comprises methods and systems to decompose contaminated plastic waste and transform it into value-added products.

This invention relates to the use of polycarboxylic acid compounds, aqueous compositions comprising the same, cosmetic compositions comprising the same, in particular, hair care compositions, and their use for the treatment of hair, and a process for the treatment of hair comprising the use of said cosmetic compositions.

There are provided ester polyols prepared from the esterification of ozone acids and branched primary polyols. There are also provided ester polyol esters prepared from an ester polyol of the invention and further esterifying the ester polyol with at least one carboxylic acid to produce at least one ester polyol ester. There are also provided rigid or flexible foams prepared using the ester polyols and/or ester polyol esters of the invention. There is also provided a coating prepared from the ester polyols and/or ester polyols esters of the invention.

This invention relates to a process for the purification of dicarboxylic acids obtained from the hydrolysis of carboxylic acid triglycerides having more than one acid functional group. The process comprises in particular the separation of at least some of the glycerine from the hydrolysis product in an aqueous phase, evaporating and/or distilling the resultant organic phase and recovering at least some of the evaporated and/or distilled dicarboxylic acids through at least one crystallisation operation.
