Formula H has the perfume compound carrying capacity of 5% on hydrotropic agent, uses 28 parts of diglycol stearates to 12 parts of Steareth-2.
Interpretation of result
Control sample:
Under the low dosage of 0.15%, perfume compound can not be detected in the drying stage from sense of smell, this is not unexpected.Under low perfume compound dosage, any free perfume compound adhering to fabric after complete wash(ing)cycle will be MIN and expection can not have impact to drying fabric.
Formula C:
Perfume compound after rinsing on fabric faintly perceives.In this, the performance of this formula is not as control sample.Weak owing to showing perfume compound performance after rinse stage, therefore unexpectedly the external drying stage can't detect perfume compound from sense of smell.
Formula D:
After rinse stage, formula D and control sample have equal performance, and good in drying stage outline, and perfume compound still faintly can perceive from sense of smell.
Formula C and D compares with control sample:
The water-soluble height of formula C ratio formula D, because it has the water soluble ingredient polyoxyethylene glycol of more a large amount.In the drying fabric of formula D perfume compound sense of smell on exist and show to have the deposition level slightly higher than the perfuming particulate of control sample or formula C.Therefore the advantage of the release postponing perfume compound in wash(ing)cycle is had, particularly when discharging under the existence of perfume compound in detergent active.
But although water-soluble lower than control sample, the performance of formula C is not as control sample.Therefore, the mechanism of wash(ing)cycle has effect.The perfuming particulate of the D that there is realistic possibility that some perfuming particulates lose at bleeding stage and this possibility is also applicable to fill a prescription.Perfuming particle loss amount assuming that fill a prescription in wash(ing)cycle between C and formula D is similar, then the amount being discharged into the perfume compound in wash(ing)cycle by lower than 0.15% control sample.
Under the existence of detergent active, the perfume compound of control sample release 0.15% is in the washing stage.A part for this perfume compound of 0.15% will be lost as emulsified substance matter and lose in bleeding stage due to detergent active.Therefore, in this perfume compound of 0.15%, only a part will deposit on fabric.
Water-soluble low than control sample of perfuming particulate of formula C, therefore under detergent active exists, the release of perfume compound postpones to the centre of washing stage or ending phase.The a part of perfume compound discharged in this stage is by by detergent active (that is, be not attached to other detergent active) from the emulsification dirt of the fabric institute's emulsification dissociated.It is expected that, some perfuming particulates can not will utilize at rinse stage physics to discharge perfume compound in bleeding stage loss.Because the performance of the C that fills a prescription after rinse stage is not as control sample, therefore be enough to show that the amount of the perfume compound be deposited on fabric is lower.Therefore, the C that fills a prescription is lost to the semi-invariant of detergent active and bleeding stage more than control sample.
Formula D is than formula C water-soluble low and sense of smell shows better than control sample.Due to still can perception perfume compound (this is contrary to the C that fills a prescription control sample) in drying fabric, therefore fabric deposited the perfume compound of higher amount.Assuming that loss and can not to utilize with the amount of release through encapsulating the micro-material of perfuming of perfume compound for formula C and formula D at rinse stage physics be similar (being used in detergent powder with identical dosage because of them) in bleeding stage, then the amount that will be as being lost by the emulsified substance of detergent active institute emulsification of difference.The release that perfume compound is more late under the existence of detergent active compared to formula C makes the amount as being lost by the emulsified substance of detergent active institute emulsification lower.Therefore, the perfume compound of higher amount discharges at rinse stage, and now, the concentration of detergent active is significantly lower.
Formula E:
With the drying stage after rinse stage, the performance of formula E is all better than control sample, formula C and D, shows have the perfume compound of higher amount to be deposited on fabric.
Formula E is similar in amount and the composition of encapsulating material with the D that fills a prescription.But the perfume compound carrying capacity on hydrotropic agent is 10% of 5% instead of formula D.Therefore, for making perfume compound be 0.1%, in detergent powder, the amount of perfuming particulate is 1.4% of 2.8% instead of formula D.
Mechanism due to wash(ing)cycle had been discussed and had been similar for formula E and the D that fills a prescription, therefore the amount of perfuming particulate that difference will be to lose in bleeding stage.Loss each perfuming particulate for formula E for containing 5% perfume compound and for formula D for containing 10% perfume compound.If loss perfuming particulate quantity for formula E and formula D be similar, then accumulation get up, fill a prescription D will lose the perfume compound of higher amount in bleeding stage.Therefore, the E that fills a prescription will deposit the perfume compound of higher amount on fabric than formula D.
In this, what is interesting is and notice, by reducing the perfume compound carrying capacity on perfuming particulate, in the perfume compound deposition on fabric, have appreciable beneficial effect.This deviates from mutually with the method for prior art, and the encapsulating process of prior art concentrates on increases perfume compound carrying capacity on capsule to usual 20% to higher than in the scope of 40%.In wash(ing)cycle, when the perfuming capsule that perfume compound load is 20% to 40% loses in bleeding stage, it represents the loss of this perfume compound of 20% to 40%, the perfume compound carrying capacity of this and perfuming particulate be 5% to 10% the present invention form contrast.Similarly, when perfuming capsule designs is dissolving or disintegration immediately in presence of water, it will discharge perfume compound and therefore will have higher amount by the emulsification of detergent active institute under the existence of detergent active.
Formula F:
Formula F is similar to formula E, and hydrotropic agent has the perfume compound carrying capacity of 5%, but replaces water soluble ingredient polyoxyethylene glycol with nonionic Ceteareth-12.Show similar to control sample and similar to formula C part.Therefore, formula F is applicable to about control sample and the mechanism of the wash(ing)cycle of formula C.
Formula G:
Formula G is similar to formula F, but replaces nonionic Ceteareth-12 to have compared with low water solubility degree or compared with another nonionic Steareth-2 of low hlb.Outperform formula F and control sample, after rinsing, all have good Olfactive evaluation with drying stage.
The mechanism of wash(ing)cycle is identical, and difference is attributable to the non-ionic use of lower HLB, and it reduces the water-soluble of perfuming particulate.As previously discussed, the water-soluble aft section of hang-over n. to wash(ing)cycle making perfume compound of reduction.
Formula H:
Formula H is similar to formula G, but with the component stearyl alcohol that diglycol stearate replacement can not be water-soluble or hydrophobic.Show similar to formula G, therefore, the impact that the change of hydrophobic components does not have the change of water soluble ingredient to show it on the impact that it shows is large.
Embodiment 7
Carry out according to formula below the experiment introducing cation activity thing according to the program in embodiment 1 and 2.
As the control sample of the existence of anionic-cationic mixture in confirmation detergent solution, prepare two beakers with 1 premium on currency.The cation activity thing Rewoquat WE15 of 5 grams of not spiced detergent powders and 1% is added in a beaker.5 grams of not spiced detergent powders are added in contrast in another beaker.By mechanical stirrer at ambient temperature continuously stirring within 30 minutes, make the detergent powder in two beakers dissolve.Then by detergent solution in left at ambient temperature two hours.At the end of during this period of time, insoluble builder such as zeolite is deposited in the bottom place of beaker.Relatively showing of these two kinds of detergent solutions, compared with the control sample of no cationic actives, the detergent powder with the cation activity thing of 1% wants how muddyly and have more precipitation, see Fig. 1 at the bottom place of beaker.
Machine-washing according to embodiment 6 with identical not spiced detergent powder basis used in control experiment with the particulate that formula PFC and formula FC are formed.
Detergent formulation:

Detergent formulation 1 cationic active matter content is 0.1%, close to 1% in detergent formulation 2.
Washing test is analyzed:
Detergent formulation 1
Although cation activity thing content is low, to fabric slightly ramollescence, show fabric to deposited cation activity thing.Fabric there is no the particle of anionic-cationic mixture.
Detergent formulation 2
Similar to the control experiment of the existence confirming anionic-cationic mixture close to the cation activity thing content of 1% in formula, therefore, in wash(ing)cycle, form the possibility of anionic-cationic mixture higher than detergent formulation 1.But through washing any existence of fabric not shown anionic-cationic mixture.
Under normal conditions, fabric softening agent or fabric softener add when the last rinsing of laundry cycles.This method will prevent cation activity thing from forming anionic-cationic mixture because the last time in rinsing the content of Anionic Active significantly reduce.The particulate with cation activity thing formed in detergent formulation 2 is under the main washing stage is the existence in Anionic Active, but it occurs in the comparatively latter stage of wash(ing)cycle from the release of formed particulate, and now the content of Anionic Active reduces.Therefore, the cation activity thing the same comparatively latter stage in wash(ing)cycle under normal conditions that coexists is introduced and is not formed anionic-cationic mixture.
Detergent formulation 3
This formula cationic active matter content is about 3%.The dosage of 3% cation activity thing is suitable with the median doses of fabrics in general tenderizer or softener.Due to the cation activity agent amount that it is higher, therefore its possibility forming anionic-cationic mixture in wash(ing)cycle is higher than detergent formulation 1 and 2.But any existence of anionic-cationic mixture is not shown through washing fabric.
Therefore, the present invention illustrates, can postpone the release of cation activity thing under dosage higher in detergent powder.
