Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to improvements in surfactant compositions colored using colorants (pigments).

[Prior art]

In cosmetics, one color tone and one fragrance tone have a large weight in terms of commercial value, and stabilization of these has traditionally been a major issue. In general, sunlight has a large effect on the fading and discoloration of surfactant compositions containing colorants, and conventionally various UV absorbers such as oxybenzone have been incorporated into cosmetics, and appropriate UV absorbers have been incorporated into cosmetics. Although methods such as adding it to container materials have been used, the effects have not been fully satisfactory. In particular, it has been extremely difficult to prevent fading or discoloration of surfactant compositions containing a coloring agent and a fragrance.

〔the purpose〕

An object of the present invention is to provide a surfactant composition containing a coloring agent and a fragrance, which overcomes the drawbacks of discoloration and discoloration described above.

〔composition〕

According to the present invention, in a surfactant composition containing a coloring agent and a fragrance, the surfactant is characterized in that a fragrance component having at least an aldehyde group among the fragrance is blended as an easily destructible encapsulated product. A composition is provided.

The present invention is characterized in that, among the flavor components that are blended into the surfactant together with the colorant, a flavor component having at least an aldehyde group is used as an easily breakable encapsulated product. The present inventors have conducted various studies on the influence of fragrance components on the stability of dyes in surfactant compositions containing colorants and fragrances. It was discovered that this substance has a large effect on stability. Therefore,
The inventors of the present invention found that when a fragrance component having an aldehyde group was blended with a surfactant in the form of an encapsulated product together with a colorant to prevent direct contact with the colorant (pigment), fading and discoloration of the product were significantly reduced. I found that it can be improved.

The fragrance component to be encapsulated in the present invention has an aldehyde group, and includes terpene-based,
These include aromatic and aliphatic aldehydes, and specific examples include terpene aldehydes such as citral, citronellal, hydroxycitronellal, perilaldehyde, and aromatic aldehydes such as benzaldehyde. , phenylacetaldehyde, α-amylcinnamic aldehyde, α-hexylcinnamic aldehyde, anisaldehyde, heliotropin, cyclamenaldehyde, P-tert-butyl-α-methylhydrocinnamic aldehyde, etc. Among aldehydes, n-heptylaldehyde, n-octylaldehyde, n-nonylaldehyde, n-decylacylaldehyde, n-undecylaldehyde, undecylaldehyde, dodecylaldehyde, methylnonylacetaldehyde, n-tridecylaldehyde, n-tetra Examples include decylaldehyde and n-hexadecylaldehyde.

In the present invention, one or more of these fragrance ingredients may be encapsulated as they are in the capsule, or if necessary, these fragrance ingredients may be dissolved in one or more oils in which they are soluble. It may also be encapsulated in a capsule.

The oil in this case is preferably liquid at room temperature, and includes vegetable oil, animal oil, hydrocarbon oil, ester oil, silicone oil, etc. Specific examples thereof include, for example:
Vegetable oils include grapeseed oil, safflower oil, soybean oil, sesame oil, corn oil, rapeseed oil, sunflower oil, cottonseed oil, avocado oil, almond oil, olive oil, sasanquat oil, camellia oil, persic oil, castor oil, peanut oil,
Jojoba oil, etc.; Animal oils include tar oil, mink oil, etc.; Hydrocarbon oils include liquid paraffin, squalane, etc.; Ester oils include isoprobyl myristate, isopropyl balmitate, butyl stearate, hexyl laurate, isononylisononanate, isotridecylnonanate, 2-ethylhexylno(lumitate,

The capsule of the present invention is insoluble or sparingly soluble in water and oil, and is intended to separate the contained flavor component and the oil component in which the flavor component is solubilized from the continuous phase of the surfactant composition. When using the product, it can be easily destroyed with fingers, palms, etc. Such capsules and encapsulation techniques are conventionally known. The particle size of the capsule is 5μ to 10mm, preferably 30μ to 511+1. In the present invention, gelatin-based capsules prepared by a coacervation method are preferably used as capsules, but in addition,
Any capsule that is insoluble or poorly soluble in water and oil and can be easily destroyed by manual stress such as fingers or palms can be used as the capsule of the present invention. Also,
In the present invention, even for water-soluble capsules, an electrolyte is added to the surfactant composition, or a solvent such as alcohol that is a poor solvent for the capsule wall material is added to dissolve the capsule wall material. Defense J! :, can be used by. In the case of the present invention, it is not necessary to encapsulate all of the fragrance components having an aldehyde group, and trace components that do not particularly promote discoloration or fading of the product may be present in the composition in an unencapsulated state. good.
