A method of covalently bonding a modifier to a polymeric microcapsule wall, which wall comprises entities capable of reaction with acrylic moieties, comprising the provision on the wall of a linking compound to which the modifier is subsequently attached, the linking compound having the Formula I

##STR00001##

in which

n=1 to 30; R.sub.1, R.sub.2 and R.sub.3 are independently selected from the following moieties:

R.sub.1 and R.sub.3 are H and Me; and

X is selected from O and NH; and

R.sub.2 is selected from CH.sub.2, CH.sub.2CH(OH)CH.sub.2, and CH.sub.2,CH.sub.2.

Microcapsuies thus modified exhibit enhanced substantivity to substrates such as textiles when used in laundry preparations.

An improved cleaning composition in block form is described. The composition addresses the consumer issues of having a clear product that remains clear through the life of the product and also has favorable handling properties such as a high melting point and increased hardness. The improvements are the result of three essential ingredients of particular block copolymer nonionic surfactants, alkanecarboxylic salts, and particular solvents at restricted proportions in the overall composition that are molded into a cleaning composition in block form that exhibits a high melting point, hardness and high optical transmittance.

The present invention is directed to a method for producing advantageous microcapsules. Moreover, the present invention provides microcapsules obtained/obtainable by the method according to the invention.

Disclosed is a composition including controlled release particles, wherein each of the controlled release particles includes: (a) a core including at least one hydrophobic active ingredient; and (b) a wall at least partially surrounding the core and including: (i) an organofunctional silane; (ii) an epoxy; (iii) an amine; (iv) an isocyanate; (v) an epoxide curing agent; wherein the controlled release particles are effective to retain the at least one hydrophobic active ingredient upon exposure to water and effective to release the at least one hydrophobic active ingredient in response to friction. A method for preparing the composition is also disclosed.

The present invention relates to personal care compositions comprising malodor reduction compositions and methods of making and using such personal care compositions. Such personal care compositions comprising the malodor control technologies disclosed herein provide malodor control without leaving an undesireable scent and when perfume is used to scent such compositions, such scent is not unduely altered by the malodor control technology.
