Description

Fragrance additives for fabric softeners, and fabric softeners separately including the fragrance additives and the fabric softener base TECHNICAL FIELD OF THE ART OF SOLUBLE FRAGRANCE ADDITIVE FOR FABRIC SOFTNER

The most basic components constituting the fabric softener are cationic surfactants and fragrance components.

The cationic surfactant performs basic functions such as improving the flexibility of the fiber and preventing static electricity, and the fragrance component is a component that gives a function of masking odors or changing mood when wearing clothing.

In conventional fiber softeners, products have been released in a state in which these cationic surfactants and aroma components are mixed, but often have a fatal effect on each other's components when time passes with these components mixed. As an example, the original fragrance is altered to show an unintended odor or by cationic surfactants, especially cationic surfactants having ester bonds, are hydrolyzed and separated into fatty acids, thereby acting as a cationic surfactant. When it is lost and severe, it can cause serious contamination of clothing.

On the other hand, consumer demand for aromas in fabric softeners has increased, and in accordance with the trend of well-being culture, the aromas preferred by consumers have become very diverse. Accordingly, consumer demand for various fragrances such as perfume type, natural extract-based fragrance, herbal fragrance, and aromatherapy fragrance has been expressed. Sometimes, products with a weak flavor are preferred, but consumers are difficult to use other than the manufacturer's customized products. It is reality.

Hereinafter, preferred embodiments of the present invention will be described. However, the following examples are only preferred embodiments of the present invention, and the present invention is not limited by the following examples.

Currently, the commercially available fiber softener composition has a problem in that the content of water is 80% or more, and the ester bond of the cationic surfactant is easily hydrolyzed. While this hydrolysis phenomenon affects the decomposition of fragrance, the fragrance also accelerates hydrolysis. To confirm this phenomenon, samples such as Comparative Examples 1 to 3 below were prepared.

Comparative Example 1 (Fiber softener containing a cationic surfactant and a fragrance component)

A fabric softener containing fragrance was prepared by mixing 6% by weight of a cationic surfactant, 2% by weight of a fragrance+nonionic surfactant+solvent, and 92% by weight of distilled water.

Comparative Example 2 (Fiber softener containing no fragrance component)

A fiber softener containing no fragrance was prepared by mixing 6% by weight of a cationic surfactant and 94% by weight of distilled water.

Comparative Example 3 (cationic surfactant emulsification system)

A cationic surfactant emulsification system was prepared by mixing fragrance + nonionic surfactant + 2% by weight of solvent and 98% by weight of distilled water.

For the samples of Comparative Examples 1 to 3, the content and odor of fatty acids produced by standing at 50° C. for 0 days, 15 days, 30 days, 45 days, and 60 days were measured, and the results are summarized in Table 1 below. Did.

Stability test (50 ℃) Comparative Example 1 Comparative Example 2 Comparative Example 3 0 days Fatty acid content 0.07% - 0.06% Odor (5 point scale, sensuality) 4.0 4.0 - 15th Fatty acid content 0.4% - 0.3% Odor (5 point scale, sensuality) 3.8 4.0 - 30 days Fatty acid content 0.8% - 0.6% Odor (5 point scale, sensuality) 3.0 4.0 - 45 days Fatty acid content 1.4% - 1.1% Odor (5 point scale, sensuality) 2.4 3.8 - 60 days Fatty acid content 2.8% - 2.3% Odor (5 point scale, sensuality) 1.2 3.8 -

As shown in [Table 1], it was found that the cationic surfactant and fragrance of the ester bond inhibited long-term storage stability of each other.

It is shown that as described above, aldehydes and ketones, one of the main components of the fragrance, cause decomposition of the cationic surfactant, and the decomposed cationic surfactant ingredient causes decomposition of the perfume ingredient.

In addition, the hydrolyzed cationic surfactant emulsion has a bad smell, which greatly affects the preference of the final product.
