Examples

Perfume formulations for use in cleaning compositions are formulated in two parts. One part contained detergent-labile ingredients (designated as "Fragile") to be incorporated into the starch encapsulating formulation. Another part is to be added directly to the detergent composition base, which contains detergent-stable ingredients (designated as "firm (Robust)"). The proportions of the two part perfume are as formulated so that the combination of the two will provide a complete perfume.

The "brittle" components are shown in table 1, and the "robust" in table 2. The perfume content of the starch encapsulated fraction was 50% by weight of the individual particles.

TABLE 1

Starch encapsulated perfume parts ("fragility")

TABLE 2

Complete perfume ("fragility" + "firmness") -see sample d below-with olfactory description described as fruity, faint scent, pear scent, aldehydic, musk, sunflower scent.

Using the following formulation, an encapsulated perfume was prepared as follows.

The emulsion was prepared as follows:

to tap water (46.0 portions) was added octenyl succinic starch sodium E1450(22 portions) and mannitol 60(5 portions). The resulting mixture was first stirred manually with a stainless steel bar and then homogenized with an IKA T25 Ultra-Turrax homogenizer at 13,500rpm to obtain a homogeneous solution. To the resulting mixture was added essential oil (27 fractions). High shear mixing was then performed at 22,000 and 24,000rpm for 20-30 minutes using the same homogenizer to produce an emulsion.

The emulsion was spray dried using a LabPlant SD-06 spray dryer using the following parameters:

spray droplet size between 0.5 and 2 μm (controlled by dynamic light scattering)

Inlet temperature: 190 deg.C

Outlet temperature: 90 deg.C

Rotation speed of peristaltic pump: 485 mL/h

Air flow rate: 3.7m/s

The resulting spray was a dry powder.

(a) Preparation of detergent compositions

The base material formula comprises: a powder detergent base ("PD base") was prepared as follows:

name of Compound	CAS	Composition by weight (%)
			Sodium Linear alkyl benzene sulfonate	68411-30-3	14
Sodium aluminosilicate	1344-00-9	15
			Sodium sulfate	7757-82-6	QS to 100
Sodium carbonate	497-19-8	13

This base was used to prepare the following detergent compositions to compare the findings of the two groups.

Group 1:

sample a PD base incorporates 0.72% by weight of a starch encapsulated "brittle" component-since the encapsulated material contains 50% perfume, this gives a loading of "brittle" perfume of 0.36%

Sample b: PD samples were spiked with 0.36% of unencapsulated "friable" component

Group 2:

sample c: PD base incorporates 0.72% starch encapsulated "friable" component + 0.04% of "firm" component

Sample d: the PD base stock incorporates 0.36% of the unencapsulated "friable" component + 0.04% of the "firm" component

Note: sample d corresponds to the entire perfume (mixture of "brittle" and "firm" components)

The sample preparation method comprises the following steps:

group 1:

sample a: to the PD base (99.28% by weight of the total mixture) 0.72% starch encapsulated "friable" was added and mixed thoroughly to homogenize.

Sample b: to the PD base stock (99.28% by weight) was added 0.36% unencapsulated "friable" and mixed thoroughly to homogenize.

Group 2:

sample c: to the PD base (99.24% by weight of the total mixture) 0.72% starch encapsulated "fragile" + 0.04% "firm" was added and mixed thoroughly for homogenization.

Sample d: to the PD base (99.24% by weight of the total mixture) 0.36% unencapsulated "friable" + 0.04% of "firm" was added and mixed thoroughly to homogenize.

Samples were prepared and kept immersed at room temperature for 5 days. One set of samples was maintained at 45 ℃ and evaluated on day 30. To check the performance of the perfume, the cloth was washed with detergent according to the following protocol:

(b) testing of detergent compositions:

detergent wash test solutions were prepared as follows:

(i) the wash mixture is:

group 1: sample a and sample b

Group 2: sample c and sample d.

Wash test evaluation the sample preparation protocol was performed as follows:

(ii) taking 4 bowls with the capacity of about 3-4 liters;

(iii) 6g of samples a, b, c and d were added to 1.5ltr in the bowl and mixed by hand;

(iv) adding two small towels into each of the 4 bowls, and allowing the bowls to be soaked for 30 minutes;

(v) the towel was manually rubbed 10 times in the wash solution in such a way that someone removed the stain from the fabric.

(vi) One towel of each pair was rinsed and then rubbed 5 times in 1.5L of clear water (simulating the hand wash described in (v)). This step is then repeated.

(vii) The rinsed towels are squeezed out, while the towels that have not been rinsed remain in the bowl.

The unwashed towel in the bowl was lifted from the bowl by pliers for testing by a panel of experts. The aroma intensities of the two were compared and a range of 0-5 was used, where 0 means no perfume detected, 3 means good and 5 means very strong. Furthermore, olfactory qualities were also evaluated compared to the complete perfume.

It is noteworthy that not only was the fragrance of the sample using starch encapsulated perfume stronger than that of the unencapsulated perfume, but the sample using starch encapsulated retained much more of the olfactory qualities of the complete perfume.
