equilibrium system polymers has the potential to decrease the neat product odor intensity of the neat product (usually more so in the case of pre-loaded standard system). Deposition of such polymers may serve to “?atten” the release pro?le and provide increased longevity. As indicated above, such lon

The use of the present invention, Which combines FMOT and SMOT PDTs, may address the problem caused by the use of said SMOT or TMOT PDT that is intended to provide bene?t during or after

For example, cyclodextrin and/or SEA may be individually loaded With perfume and formulated into a granular laundry detergent, Which may provide a burst or bloom of perfume intensity upon product use.

For example, the encapsulation of perfume by a
polymer Wall or matrix alloWs the perfume to be protected from harsh product conditions and alloWs increased perfume

PDT(s) described herein. [0064] Another advantage of the present invention is that the release pro?le or release rate may be modi?ed by using combinations of FMOT and SMOT PDTs. A particular PRM may have properties that make it di?icult to provide a desired headspace level, for example, if the PRM has a loW vapor pressure When present With other formulation ingredients such as surfactant. The use of a FMOT PDT may alloW such

For some PMC systems, PRMs that leak most readily include those With loW CLogP value and/ or loW Kovats Index (KI) value, including PRMs that are referred to as “top notes”; PAD and AAD PDTs may be used to improve the delivery of such PRMs. Another option to leverage TMOT combinations is to add additional free PRMs, including top

notes, separately from the PMC, and use a PAD and/ or AAD
technology to improve the deposition of said separately added PRMs, in combination With a PMC system to improve the deposition and/ or release of other PRMs. The PAD and/or
AAD system that may be used to improve also the deposition of the PMC may be pre-loaded With perfume or added sepa
rately from the perfume to the product matrix, thus improving both deposition of free PRMs and PMC, and optionally modi fying the release pro?le of free perfume and/or encapsulated perfume from the situs. [0071] In addition to balancing the overall character and intensity by using combinations of TMOT PDTs to delivery different perfumes, perfume accords, or PRMs, another advantage to using combinations of TMOT PDTs is to
improve the overall deposition and release pro?le of PDTs. For example, cationic polymers and/or other additives may be used to increase the deposition of PMC on the situs. In addi tion such additives can modify the release pro?le of perfume
from PMC. Without being bound by theory, the perfume release may be modi?ed by the ability of the additive to increase or decrease the Wall porosity or modify the diffusiv ity of the Wall to the internal or external phase. Also, Without being bound by theory, the additive may serve as a perfume

character and intensity; hoWever, the release of only a feW PRMs can lead to a less complex scent character or even a
polarizing or unpleasant scent experience. This issue can be
addressed by balancing the scent character and intensity With PRMs delivered from other TMOT PDTs. For example, the use of a perfume microcapsule (PMC) and a pro-perfume may provide a scent experience that is superior to either PDT
that is used individually. [0076]
This invention also includes the use of TMOT PDT
combinations to provide greater scent intensity and improve scent character at different consumer touch points. For
example, the TMOT PDT combination may provide desirable scent soon after the situs is dry, and also at much later time
points. The problem With trying to address the need for sus tainedperfume release over long time periods is that too much perfume may be needed to achieve the desired results. This is especially the case if the PRMs are volatile and dissipate too quickly or have a high odor detection threshold (ODT) and have to be used at levels that are not practical given the
theoretical perfume loading limits of the PDT. This need is addressed through the use of TMOT PDT combinations in
Which perfume release is triggered at different time points. For example, a polymer-assisted delivery TMOT PDT may provide scent shortly after the situs is dry, and an enzyme triggered pro -perfume may release perfume from clothes that are stored in a hamper Waiting to be laundered. The use of PDT combinations also alloWs the formulator to hide or sup
sink for PRMs that are released from the PMC either prior to
press portions of the perfume until the release of said perfume
or after a triggered release.

In another aspect of the present invention, select
PRMs are able to diffuse through the Wall of the PMC. Such diffusion may be desirable to achieve sustained perfume release; hoWever, in other cases the release of such PRMs is considered too fast and results in a de?ciency of certain PRMs and a change in the preferred character or intensity. The use of
fume release is one means to achieve this goal, in Which the headspace of some PRMs carried by one of the TMOT PDTs
is suppressed, until release is imtiated by the desired trigger. [0077] Another example of a combination of tWo or more TMOT PDTs includes a starch-coated perfume-loaded Zeo

equilibrium system polymers has the potential to decrease the neat product odor intensity of the neat product (usually more so in the case of pre-loaded standard system). Deposition of such polymers may serve to “?atten” the release pro?le and provide increased longevity. As indicated above, such lon

For example, one combination option is to include the same FMOT PDT on different parts of the product but select dif
ferent perfume accords for different samples. For example, one FMOT PDT could contain a higher percentage of top notes With a Kovats index (KI) value in the range of 800 to 1200, Whereas another hot melt might contain more middle notes or PRMs With a Kovats index (KI) value in the range of
1200-1500, Whereas yet another might contain base notes With a Kovats index (KI) value>1500. This Would have the

including but not limited to, hair shampoos and conditioners, body Washes, including those With one or more separate
phases, bar soaps, antiperspirants, deodorants, and the like. For such products, the perfume bloom during the use of the product in its neat or Water-diluted form is important to the SMOT consumer experience. [0059] Using SMOT PDT or PDTs may provide increased
perfume intensity or perfume bloom during product use, including in cases in Which the perfume release is triggered by
perfume plastics, the system can be improved by selecting
moisture, such that the scent may be experienced, even ?lling the room, When the product package is not present or When the FMOT PDT is not providing su?icient scent in combination With the perfume associated With the neat product. [0060] Any of the PDTs described Within may be used in

The use of the present invention, Which combines FMOT and SMOT PDTs, may address the problem caused by the use of said SMOT or TMOT PDT that is intended to provide bene?t during or after
product use. For example, cyclodextrin and/or SEA may be individually loaded With perfume and formulated into a granular laundry detergent, Which may provide a burst or bloom of perfume intensity upon product use. The scent intensity and character of the neat product, hoWever, may be insuf?cient or distorted in such a Way as to decrease consumer

For example, the encapsulation of perfume by a
polymer Wall or matrix alloWs the perfume to be protected from harsh product conditions and alloWs increased perfume
deposition to the situs. Without being bound by theory, the encapsulation technology can suppress the perfume head

PDT(s) described herein. [0064] Another advantage of the present invention is that the release pro?le or release rate may be modi?ed by using combinations of FMOT and SMOT PDTs. A particular PRM may have properties that make it di?icult to provide a desired headspace level, for example, if the PRM has a loW vapor pressure When present With other formulation ingredients such as surfactant. The use of a FMOT PDT may alloW such

For some PMC systems, PRMs that leak most readily include those With loW CLogP value and/ or loW Kovats Index (KI) value, including PRMs that are referred to as “top notes”; PAD and AAD PDTs may be used to improve the delivery of such PRMs. Another option to leverage TMOT combinations is to add additional free PRMs, including top

technology to improve the deposition of said separately added PRMs, in combination With a PMC system to improve the deposition and/ or release of other PRMs. The PAD and/or
AAD system that may be used to improve also the deposition of the PMC may be pre-loaded With perfume or added sepa
rately from the perfume to the product matrix, thus improving both deposition of free PRMs and PMC, and optionally modi fying the release pro?le of free perfume and/or encapsulated perfume from the situs. [0071] In addition to balancing the overall character and intensity by using combinations of TMOT PDTs to delivery different perfumes, perfume accords, or PRMs, another advantage to using combinations of TMOT PDTs is to
improve the overall deposition and release pro?le of PDTs. For example, cationic polymers and/or other additives may be used to increase the deposition of PMC on the situs. In addi tion such additives can modify the release pro?le of perfume
from PMC. Without being bound by theory, the perfume release may be modi?ed by the ability of the additive to increase or decrease the Wall porosity or modify the diffusiv ity of the Wall to the internal or external phase. Also, Without being bound by theory, the additive may serve as a perfume

character and intensity; hoWever, the release of only a feW PRMs can lead to a less complex scent character or even a
polarizing or unpleasant scent experience. This issue can be
addressed by balancing the scent character and intensity With PRMs delivered from other TMOT PDTs. For example, the use of a perfume microcapsule (PMC) and a pro-perfume may provide a scent experience that is superior to either PDT
that is used individually. [0076]
This invention also includes the use of TMOT PDT
combinations to provide greater scent intensity and improve scent character at different consumer touch points. For
example, the TMOT PDT combination may provide desirable scent soon after the situs is dry, and also at much later time
points. The problem With trying to address the need for sus tainedperfume release over long time periods is that too much perfume may be needed to achieve the desired results. This is especially the case if the PRMs are volatile and dissipate too quickly or have a high odor detection threshold (ODT) and have to be used at levels that are not practical given the
theoretical perfume loading limits of the PDT. This need is addressed through the use of TMOT PDT combinations in
Which perfume release is triggered at different time points. For example, a polymer-assisted delivery TMOT PDT may provide scent shortly after the situs is dry, and an enzyme triggered pro -perfume may release perfume from clothes that are stored in a hamper Waiting to be laundered. The use of PDT combinations also alloWs the formulator to hide or sup

PRMs are able to diffuse through the Wall of the PMC. Such diffusion may be desirable to achieve sustained perfume release; hoWever, in other cases the release of such PRMs is considered too fast and results in a de?ciency of certain PRMs and a change in the preferred character or intensity. The use of
fume release is one means to achieve this goal, in Which the headspace of some PRMs carried by one of the TMOT PDTs
is suppressed, until release is imtiated by the desired trigger. [0077] Another example of a combination of tWo or more TMOT PDTs includes a starch-coated perfume-loaded Zeo
