8450259
The present application relates to benefit agent delivery compositions, compositions, packaged products and displays comprising such benefit agent delivery compositions, and processes for making and using such benefit agent delivery compositions and compositions, packaged products and displays comprising such benefit agent delivery compositions.
Benefit agents, such as perfumes, brighteners, insect repellants, silicones, waxes, flavors, vitamins and fabric softening agents, skin care agents are expensive and may be less effective when employed at high levels in personal care compositions, cleaning compositions, and fabric care compositions. As a result, there is a desire to maximize the effectiveness of such benefit agents. One method of achieving such objective is to improve the delivery efficiencies of such benefit agents. Unfortunately, it is difficult to improve the delivery efficiencies of benefit agents as such agents may be lost do to the agents' physical or chemical characteristics, such agents may be incompatible with other compositional components or the situs that is treated, or such agents may be lost during post application processes such as rinsing or drying.
Accordingly, there is a need for a benefit agent delivery composition that provides improved benefit agent delivery efficiency. While not being bound by theory, applicants believe that the benefit agent delivery compositions disclosed herein meet such need as such compositions have increased deposition and retention properties which result in the desired increase in benefit agent delivery efficiency.

Equal amounts a perfume composition and amine-terminated Hycar® ATBN1300X42 from Noveon are weighted and mixed for five minutes using a Ultra-Turrax as needed. The ingredients are put at 60° C. in warm water bath for 1 hour before use/mixing. After mixing the mixture is put in a warm water bath at 60° C. for ±12 hours. A homogenous, viscous and sticky material is obtained.
In the same way as described above different ratios between the components can be used:
A mixture comprising 50% of a perfume composition, 40% of carboxyl-terminated Hycar® 1300×18 (CAS#0068891-50-9) from Noveon, (put at 60° C. in warm water bath for 1 hour before mixing) and 10% of Lupasol® WF (CAS#09002-98-6) from BASF (put at 60° C. in warm water bath for 1 hour before mixing). Mixing is achieved by mixing for five minutes using a Ultra-Turrax T25 Basic equipment (from IKA). After mixing, the mixture is put in a warm water bath at 60° C. for ±12 hours. A homogenous, viscous and sticky material is obtained.
In the same way as described above different ratios between the components can be used:
A mixture comprising 50% of a perfume composition, 40% of carboxyl-terminated Hycar® CTBN 1300×18 from Noveon (put at 60° C. in warm water bath for 1 hour before mixing) and 10% of Lupasol® WF (CAS#09002-98-6) from BASF (put at 60° C. in warm water bath for 1 hour before use) is formed.
Mixing is achieved by mixing for five minutes using a Ultra-Turrax T25 Basic equipment (from IKA). After mixing, the mixture is put in a warm water bath at 60° C. for ±12 hours. A homogenous, viscous and sticky material is obtained.
In a first step of the preparation the Lupasol® WF (CAS#09002-98-6) from BASF 15% is used in combination with 35% of carboxyl-terminated Hycar® CTBN1300X18 and 17% of this polymer mix is diluted with 83% of Benzyl Benzoate to make a workable solution. The materials described above are put together, in the ratio's described above, in a glass jar at 80° C. on a hot plate with stirring using a magnetic stirrer. Next the polymer premix is mixed with a perfume composition in a 1:1 ratio. This polymer—perfume mix is than added to a fabric enhancer composition.
Starting from any of Examples 1 to 3 as described above:
The resulting homogenous, viscous and sticky material is held at 60° for ±2 hours before starting the agglomeration process. Next, a mixture comprising 40% of the viscous, sticky sample and 60% of melted TAE80 is formed by combining and mixing with an Ultra-Turrax T25 Basic equipment (from IKA) for 5 to 10 minutes. Then, 1 part of the TAE80/sticky sample is very slowly added to 0.6 parts of light soda ash using a Braun kitchen robot to form agglomerates. The resulting agglomerates are then used in a powder detergent.
Starting from any of Examples 1 to 3 as described above:
The resulting homogenous, viscous and sticky material is held at 60° for ±2 hours before starting the dilution process.
The viscous sticky material obtained as described in any of Examples 1-3 above are mixed at different ratios for five minutes using an Ultra-Turrax T25 Basic equipment (from IKA), at the levels listed in the table above, with benzyl benzoate before the resulting mixture is a added to a liquid detergent.
Addition of the different ingredients without premixing of the materials:
The following are mixed without premixing/premixtures being formed.
Non-limiting examples of product formulations containing a benefit agent delivery composition are summarized in the following table.
a N,N-di(tallowoyloxyethyl)-N,N-dimethylammonium chloride.
b Methyl bis(tallow amidoethyl)2-hydroxyethyl ammonium methyl sulfate.
c Reaction product of Fatty acid with Methyldiethanolamine in a molar ratio 1.5:1, quaternized with Methylchloride, resulting in a 1:1 molar mixture of N,N-bis(stearoyl-oxy-ethyl) N,N-dimethyl ammonium chloride and N-(stearoyl-oxy-ethyl) N,-hydroxyethyl N,N dimethyl ammonium chloride.
d Cationic high amylose maize starch available from National Starch under the trade name CATO ®.
f Copolymer of ethylene oxide and terephthalate having the formula described in U.S. Pat. No. 5,574,179 at col. 15, lines 1-5, wherein each X is methyl, each n is 40, u is 4, each R1 is essentially 1,4-phenylene moieties, each R2 is essentially ethylene, 1,2-propylene moieties, or mixtures thereof.
g SE39 from Wacker
h Diethylenetriaminepentaacetic acid.
