Problems solved by technology

[0006] Perfume delivery performance of known detergent compositions remains unsatisfactory
Additionally, a disadvantage of laundry compositions containing cationic polymers is that such compositions cause yellowing (greying) of fabrics
[0007] It remains a challenge to provide a system capable of delivering fragrance or fragrance to substrates such as fabrics that maintains fragrance levels and does not involve concomitant loss of fragrance raw material due to insufficient initial delivery
It remains a challenge to provide a laundry system that is universal to all fabric types and all fabric washing conditions and does not alter the structure or appearance of the fabric

example 1

[0188] Fabric pretreatment:

[0189] -Washing machine model: Samsung Top Load(WA90F5S9)

[0190] - Detergent: Detergent without Ai Hui washing fragrance

[0191] -Dosage of detergent: 80g / 80 pieces of PECO towels

[0192] - Washing temperature: room temperature

[0193] All fabrics were washed and tumble dried in a dryer (Elba Sensordry Dual Heat EB422) to ensure that the fabrics were odor free before further use.

[0194] The liquid laundry detergent base is pre-prepared using the following recipe and procedure:

[0195] 1. Add fragrance (0.5 wt% of detergent base) to a fragrance-free liquid detergent base and allow to age overnight. First, guar gum was dispersed in water by adding guar gum powder to distilled water while stirring was continuously provided. Then, add the calculated amount of perfumed detergent base and guar gum solution to the basin for washing. For example, when 1 g of detergent base is added to a wash tub with 500 ml of water, and in this case guar ...

[0215]Following the procedure as described in Example 1, it is desired to replace the oil fragrance with the encapsulated fragrance. Fragrance intensity assessments were also performed as described in Example 1, except that the fabric was hand rubbed 5 times by a panelist before smelling the fragrance intensity.

[0216] The recipes and results are shown in Table 2 below:

[0217] Table 2

[0218]

[0219] Spice 2 is an encapsulated spice.

[0220] The results show that the amphoteric guar gum according to the invention leads to a significantly stronger fragrance on the treated fabrics.

[0222] washing program

[0223] 1. Spice and guar powder were added and dispersed in the detergent base, then 1 g of the mixture was added to a basin with 500 ml of water for washing.

[0224]

[0225] 2. After washing, remove from fabric and squeeze dry.

[0226] 3. To rinse, return the textile swatch to the clean basin with 500 mL of water. Place the pot back into the water resistance tester and spin for 3 minutes to rinse.

[0227] 4. After rinsing, remove from fabric and squeeze water dry.

[0228] 5. Dry the fabric overnight on aluminum foil at room temperature.

[0229] Fragrance Intensity Evaluation:

[0230] Fragrance intensity assessments are performed without disturbance in a clean, odor-free environment. Fragrance intensity was assessed by a panel of experts (8). The fabric was hand rubbed 5 times by the panelist before the panelist smelled the fragrance. Fragrance intensity was scored by the panelists on a scale from 1 to 10, with 1 representing the l...
