Description

Fragrance premix composition for longlasting of fragrance of liquid detergent having a fabric softening effect

The present invention relates to a fragrance premix composition for increasing the reverberation of a liquid detergent having a fiber softening effect and a liquid detergent composition comprising the same.

Generally, laundry detergents used for washing are classified into powder and liquid forms, and liquid detergents may be classified into surfactants and water-soluble organic builders or inorganic builders. Cationic polymer in quaternary ammonium salt form is used as a softening effect on the fiber. Such cationic polymers are known to adhere to clothing to exert a softening effect.

The fragrance used in the product is similar to the fatty acid group of the surfactant (aliphatic part) is characterized by being able to combine with the fatty acid group of the surfactant. The fragrance can be adsorbed by both anionic and cationic surfactants, but the anionic surfactant, which is a detergent component, is weaker than the cationic one because of its weaker adsorption on the fibers. When the fragrance is flavored in the state, the reverberation effect of the liquid detergent after washing appears to be lower than expected, and there is a limit in producing the same effect as the fabric softener. Therefore, most of the commercially available liquid detergent having a fibrous effect has a weak effect of reverberation.

Accordingly, an object of the present invention is to provide a perfume composition capable of sufficiently expressing the reverberation after washing in a liquid detergent in which an anionic surfactant and an amphoteric surfactant are used simultaneously, and a liquid detergent composition comprising the same.

To this end, the present invention provides a fragrance premix composition for increasing the reverberation of a liquid detergent having a fiber softening effect and a liquid detergent composition comprising the same.

As a result of our research, when fragrances are mixed with surfactants such as anionic surfactants, nonionic surfactants and amphoteric surfactants during the detergent manufacturing process, the perfumes are solubilized in micelles consisting of one or more large amounts of surfactants. However, it was found that it is difficult to obtain a large reverberation effect because it is more likely to be lost in the washing water rather than being adsorbed to the clothes during the washing process.

In contrast, if the fragrance is prepared in advance in the form of a premix with the cationic polymer and the amphoteric surfactant, most of the fragrance can be adsorbed to the cationic polymer and emulsified by a small amount of the added surfactant. When the fragrance premix composition thus prepared was added to the detergent base, it was confirmed that satisfactory reverberation was expected after washing as the fragrance was effectively delivered as the cationic polymer and the surfactant composite adsorbed in the washing process were adsorbed onto the garment.

The present invention therefore provides a perfume premix composition comprising a cationic polymer, an amphoteric surfactant and a perfume. The fragrance premix composition according to the present invention is to enhance the reverberation characteristics after washing of a liquid detergent containing an anionic surfactant and an amphoteric surfactant, and premixes a cationic polymer, an amphoteric surfactant and a fragrance which can be used in a liquid detergent. It is possible to achieve the desired effect of reverberation by preparing it in the form and injecting it into the manufacturing process of the liquid detergent.

The fragrance premix composition according to the present invention comprises a cationic polymer as an essential component.

In the present invention, in order to increase the reverberation of the fragrance components, the fragrance component is composed of a fragrance with excellent fiber and adsorption. The fragrance reverberation is performed by premixing the cationic polymer and the amphoteric surfactant. Improved sex.

In the present invention, the cationic polymer may be included in the range of 0.01 to 20 parts by weight based on 100 parts by weight of the fragrance premix composition.

If the amount is less than 0.01 parts by weight of coacervate is low, the adsorption of the fragrance is low, the reverberation effect is not sufficiently exhibited. If the amount exceeds 20 parts by weight, excessive performance of coacervate may interfere with the washing performance.

As such cationic polymer, it is conventionally used, for example, one or more selected from the group consisting of natural cationic polymer, synthetic cationic polymer and mixtures thereof can be used.

In the present invention, the cationic polymer is not limited thereto, for example, cationic guar (eg guar hydroxypropyltriammonium chloride, hydroxypropyl guar hydroxypropyltriammonium chloride), cationic cellulose ( Natural cationic polymers including, for example, polyquaternium-10); And dimethyldiallylammonium chloride polymer, acrylamide-dimethyldiallylammonium chloride copolymer, PVP-dimethylaminoethylmethacrylate copolymer, acrylic acid-dimethyldiallylammonium chloride copolymer, acrylamide-dimethylaminoethylmethacrylate methyl Chloride copolymer, trimethylaminoethylmethacrylate polymer, and one or more components selected from the group consisting of synthetic cationic polymers.

On the other hand, the fragrance premix composition of this invention contains an amphoteric surfactant. The amphoteric surfactant not only contributes to the reverberation of the fragrance in the fragrance premix composition of the present invention but also serves to provide a fiber softening effect.

In the present invention, the amphoteric surfactant may be included in the range of 0.5 parts by weight to 30 parts by weight based on 100 parts by weight of the perfume premix composition.

Amphoteric surfactants include structures in which anions and cations are present simultaneously in the molecular structure. For example, amphoteric surfactants contain acetic acid (-COOH) groups, sulfonic acid (-SO ₃ H) groups or sulfate (-O.SO ₃ H) groups as anions, and nitrogen groups in quaternary ammonium form as cations. It may contain. For example, as the amphoteric surfactants are the beta-carboxy doll (Carboxy betaine type ^{_{(RN + (CH 3) 2}} -CH 2 COO -) and beta sulfonate doll (sulfo betaine type ^{_{(RN + (CH 3) 2}} -CH ^{_{2 CH 2 CH 2 SO 3 -}} ) and the like can be used amphoteric surfactants, amine oxide-type amphoteric surfactants, amide amino acid-type amphoteric surfactant.

In one embodiment, the amphoteric surfactant consists of an alkylamidopropylbetaine having 8 to 22 carbon atoms, an alkyldimethylbetaine, an alkyl monoampoacetate, a coco ampocarboxy glycinate, a sacosinate and an alkyl ampodiacetate. It may be one or more components selected from the group. Preferably, alkyl amido propyl betaine having 8 to 22 carbon atoms can be used as the amphoteric surfactant.

On the other hand, in the fragrance premix composition of the present invention, the fragrance may be included in the range of 0.5 parts by weight to 20 parts by weight based on 100 parts by weight of the perfume premix composition.

Persistence of the perfume is determined by the clogP value and Vapor pressure associated with the water solubility of the perfume. clogP is a log of P, which represents the ratio of solubility of the single fragrance component in octanol and in water.The smaller the value of clogP, the more fragrant the hydrophilicity of the fragrance and the greater the clogP value. The fragrance is lipophilic, leaving a lot of reverberation. On the other hand, the fragrance is generally felt volatilized is characterized by the vapor pressure. This vapor pressure is inversely related to the boiling point of the material. In other words, the higher the boiling point of the fragrance, the lower the vapor pressure, there is a characteristic that the reverberation is increased.

In the present invention, by adjusting the solubility (Water solubility) and the vapor pressure (Vapour pressure) of the fragrance, the adsorption is good to the fiber, amphoteric surfactant, cationic polymer to set the fragrance characteristics enhanced reverberation characteristics.

As a result of the reverberant fragrance, clogP has a value of 3 or more, and a boiling point of less than 250 ° C and a boiling point of more than 250 ° C are preferably combined in a range of 9: 1 to 2: 8.

Thus, in one embodiment of the present invention, the fragrance is a combination fragrance, the combination fragrance has a clogP of 3 or more, a fragrance having a boiling point of less than 250 ℃ and a fragrance having a boiling point of 250 ℃ or more in the range of 9: 1 to 2: 8 It is characterized by being combined with. In a preferred embodiment, the combination fragrance may have a clogP of 3 or more, a perfume having a boiling point of less than 250 ℃ and a perfume having a boiling point of 250 ℃ or more in the range of 4: 6 to 6: 4. As can be seen in the following examples, it was confirmed that the effect of reverberation after washing was the best when using this combination fragrance.

Although not limited thereto, the fragrance having a boiling point of less than 250 ° C. used in the combination perfume is lavandine, lemon oil, orange oil, benzaldehyde, geraniol, Citronellal, phenyl ethyl alcohol, linalool, methyl anthranilate, alpha-methylionone, and para-tertiarybutylcyclo Hexyl acetate (p-tertiary butyl cyclohexyl acetate) may be one or more flavorings selected from the group consisting of. In addition, fragrances having a boiling point of 250 ° C. or higher are cedarwood, coumarin, coumarin, ethyl vanillin, lilial, p-tertiarybutyl α-methyl hydrocinnamic aldehyde, patchouli alcohol, Musk ketone, gamma-methylionone, and one or more flavors selected from the group consisting of galaxolide, methyl hydrojasmonate.

The addition of a nonionic surfactant to the detergent composition of the present invention can be expected to increase the basic cleaning power, as well as phase stability due to increased compatibility with other additives. When a nonionic surfactant is added to a mixture of anionic surfactant and cationic polymer, the nonionic surfactant forms a mixed micelle with the anionic surfactant and the cationic polymer. The mixed micelle thus formed becomes more stable and solubilizes the precipitates which do not form micelles, thereby reducing the settling area and increasing phase stability. Such nonionic surfactants may be included in the range of 0.1 to 50 parts by weight based on 100 parts by weight of the total liquid detergent composition of the present invention.
