Abstract
A process for preparing a composition, said composition comprising a fabric softening active, an encapsulated perfume and a non-confined perfume, wherein the process comprises the step of dispersing the encapsulated perfume in water before the addition of the fabric softening active to the water, leads to dispersibility and visual benefits without damage to the encapsulates.
Description
Technical field
The present invention relates to be prepared in the method for the encapsulated spices in the fabric softener composition.
Background technology
The advantage of the encapsulated perfume composition (capsule) of use in fabric conditioner is that it can improve the storage of spices and perfume composition and sends.Through in capsule, protecting spices to overcome the problem of perfume loss in drying process, this technology has the flavor delivery than the free spice oil improvement of routine.
Capsule self is frangible relatively and comprises exhaustive volatile perfume composition when capsule wall breaks.Therefore, in typical preparation method, capsule is added in the activated mixture to protect them in said preparation technology's later stage.Usually, add the trace ingredients of hot water and for example skimmer and sanitas, will soften activeconstituents simultaneously and melt separately.Before cooling, the fusion activeconstituents is under agitation joined in the hot water then.Only just encapsulated spices and any free spice oil are joined in the said mixture together after this.Thisly add capsular sequence of steps later on again the fusion activeconstituents being joined aqueous phase, help to protect frangible capsule and will to these relatively the destruction of fragile component reduce to minimum.
But the problem of existence is the poor dispersion of capsule in the finished product, causes condensing.The result is that visual appearance is poor, and unstable properties.
Still need capsule be added the method in the compsn of fabric finishing agent composition for example, this method makes that capsule being separated in final composition is acceptable.
Unexpected, we have been found that now add the fusion activeconstituents mutually before, capsule is added aqueous phase has obtained good dispersion and corresponding good visual performance and stable high-performance, simultaneously capsule is not produced any significant damage.
Summary of the invention
In first aspect of the present invention; A kind of preparation method for compositions is provided; Said composition comprises quaternary ammonium salt fabric-softening activeconstituents, encapsulated spices and the not limited spices that ester connects; Wherein, said method is included in the fabric-softening activeconstituents is dispersed in the step in the water with encapsulated spices before being added to the water, and said compsn does not contain calcium chloride and benzalkonium chloride.
In second aspect of the present invention, a kind of compsn that can be obtained by the method according to first aspect present invention is provided.
Embodiment
Method
In the method for the invention, before adding the fusion activeconstituents, said encapsulated spices is joined aqueous phase.Said water also can comprise minor component, for example sanitas and skimmer.
It is about 20 to 100% that the ratio that before adding the fusion activeconstituents, joins the encapsulated spices of aqueous phase should be, and is preferably 50 to 100%, and more preferably 80 to 100%, most preferably be 100%.
After with said activeconstituents and water mixing and cooling, not limited spice oil is added in a usual manner.
A preferred method of the present invention comprises the steps:
1) with flavor capsule and optional trace ingredients for example sanitas mix with hot water with the formation water with skimmer;
2) the fabric-softening activeconstituents is melted the formation melt;
3) mix said water and said melt;
4) make the cooling of gained mixture; And
5) any not limited spice oil is joined in the said cooled mixture.
The fusion activeconstituents is added into aqueous phase, and wherein said water comprises flavor capsule.Preferably 100% fusion activeconstituents was added in this stage, a small amount of fusion activeconstituents is joined aqueous phase before adding capsule though the present invention also is encompassed in.Refer on a small quantity, for example, 0.0001 to 25 %, for example 20 or 10%.

The useful component of spices comprises the material in natural and synthetic source.They comprise simplification compound and mixture.The specific examples of these compositions can find in present document, Fenaroli's Handbook of Flavor Ingredients for example, 1975, CRC Press; M. the Synthetic Food Adjuncts of B. Jacobs work, 1947, Van Nostrand compiles; Or the Perfume and Flavor Chemicals of S. Arctander, 1969, Montclair, N.J. (USA).These materials are known as far as the technician in the following field: make the consumer's goods be full of fragrance, in the consumer's goods, add spices and/or add the field of fragrance to the consumer's goods; Promptly; Give a kind of smell of the consumer's goods and/or the fragrance or the taste of fragrant traditionally or fragrance, or the field of improving the smell and/or the taste of the said consumer's goods.
In this article, spices not only refers to the product perfume of complete formula, and refers to the selected component of said perfume, those components that are easy to lose particularly, for example so-called " top is fragrant ".
The top is fragrant by Poucher (Journal of the Society of Cosmetic Chemists 6 (2): 80 [1955]) define.The fragrant instance in known top comprises citrus oil, linalool, linalyl acetate, lavandula angustifolia, dihydro myrcenol, rose oxide and suitable-3-hexanol.The fragrant 15-25%wt that accounts for flavor compositions usually in top, and in fragrant those embodiments in the top that comprises increasing amount of the present invention, there is 20%wt at least in imagination in capsule.
Advantageously encapsulated perfume composition (promptly will distribute those components that get in the water) with low Clog P preferably has the Clog P less than 3.0.These materials with low relatively boiling point and low relatively Clog P are called as " late blooming " perfume composition, and comprise following material:

The preparation of compsn 1
1. under agitation heat water to 65 ℃.
2. add skimmer and sanitas.
3. then the capsule slip is joined aqueous phase and stirred 2 minutes.
4. join aqueous phase with the fusion of fabric-softening activeconstituents and in 3-5 minute.
5. add hydrochloric acid then to required pH, and dyestuff is added in the mixture.
6. grind products therefrom then until reaching required viscosity.
7. then product is cooled to 45 ℃.
8. then free spice is joined in the cooled product.
The preparation of Comparative Examples A
1. under agitation heat water to 65 ℃.
2. add skimmer and sanitas.
3. join aqueous phase with the fusion of fabric-softening activeconstituents and in 3-5 minute.
4. add hydrochloric acid then to required pH, and dyestuff is added in the mixture.
5. grind products therefrom then until reaching required viscosity.
