Description

Technical Field

[0001] The present invention relates to an aromatic composition, a pretreatment composition, a skin and / or hair treatment set, and a method for improving aroma persistence.

Background Art

[0002] Conventionally, various fragrances have been blended in types of detergents that are rinsed away, such as shampoos, conditioners, body soaps, and laundry detergents. By blending fragrances in this way, the fragrance remaining on hair, skin, clothes, etc. not only during but also after the use of the detergent can impart comfort not only to the user himself / herself but also to people around. Therefore, the fragrance used in products is required to be attractive during use and at the same time excellent in the persistence of the fragrance after use. However, due to the form of these detergents being rinsed away, it is not easy for the fragrance to remain on hair or skin, and it is not easy to make the fragrance last after use.

[0003] As a method for improving the residual fragrance property after rinsing, in hair care products such as shampoos and conditioners, a method of enhancing the residual fragrance property by combining a cationic surfactant, a saturated monohydric higher aliphatic alcohol, a specific amino-modified silicone, and a fragrance component, a method of improving the persistence of the fragrance by blending specific components in a certain ratio in the first agent and the second agent, etc. are known (see Patent Documents 1 and 2, etc.). However, with these conventional methods, the persistence of the fragrance after rinsing is not sufficient.

[0008] According to the present invention, by using the above-mentioned pretreatment composition on the skin or hair and then using the above-mentioned aromatic composition, the fragrance of lactone compounds and monoterpenoids can be strongly and continuously sustained on the skin or hair for a long time as compared with the case of using the aromatic composition alone.

Embodiments for Carrying Out the Invention

[0009] The present invention relates to a method for strongly and continuously sustaining the fragrance of lactone compounds and / or monoterpenoids in the above-mentioned aromatic composition on the skin or hair by using an aromatic composition containing specific lactone compounds and / or monoterpenoids and a gemini surfactant after using a pretreatment composition containing acyl hydrolyzed protein and / or its salt on the skin or hair. The present invention also includes the pretreatment composition and the aromatic composition used in this method, as well as a skin and / or hair treatment set containing the above-mentioned pretreatment composition and aromatic composition. The present invention will be described in detail below. In addition, the terms used in this specification are interpreted in the meaning usually used in the technical field unless otherwise specified.

[0010] <Method for Improving the Fragrance Persistence of Lactone Compounds and / or Monoterpenoids> The method for improving the fragrance persistence of lactone compounds and / or monoterpenoids of the present invention is characterized in that after using a pretreatment composition containing acyl hydrolyzed protein and / or its salt (hereinafter, also simply referred to as “component (A)”) on the skin and / or hair, (B) (B-1) a lactone compound and / or monoterpenoid represented by the following formula (I) (hereinafter, also simply referred to as “component (B-1)”), and (B-2) a gemini surfactant (hereinafter, also simply referred to as “component (B-2)”) (hereinafter, also simply referred to as “component (B)”) are used.

[0011] According to the method of the present invention, by using the above pretreatment composition on the skin or hair and then using the above aromatic composition, the aroma due to lactone compounds and monoterpenoids can be strongly and continuously maintained on the skin or hair for a long time compared to the case of using the aromatic composition alone. Hereinafter, the pretreatment composition and the aromatic composition used in the method of the present invention will be described.

[0012] [Pretreatment composition] The pretreatment composition in the present invention is a composition containing (A) acylated hydrolyzed protein and / or its salt.

[0013] 〈(A) Acylated hydrolyzed protein and / or its salt〉 The acylated hydrolyzed protein or its salt is a condensate of a protein hydrolyzate and a fatty acid or its salt. Since it is a protein-based surfactant, it is less likely to cause protein denaturation and has little penetration into the skin, hair, etc. Therefore, it has low irritation and is also excellent in the protective and softening effects on hair and skin, so it has become one of the important bases as a cleaning component in detergents. By containing this component, the pretreatment composition of the present invention can form appropriate foam and remove dirt while suppressing damage to hair and skin, so it is preferably used as a detergent.

[0014] Examples of the protein from which the acylated hydrolyzed protein or its salt is derived include keratin, collagen, silk (silk protein), elastin, conchiolin, milk casein, soy protein, wheat protein, etc. Among these, keratin, collagen, and silk are preferred, and keratin is particularly preferred.

[0057]

Table 3

[0058] Each composition was used on hair by the following method. (1) After lightly washing a bundle of hair (also referred to as a hair bundle, 10 cm in length and 1 g in weight) with warm water at 40°C, excess moisture was removed, and 0.5 g of the pretreatment composition (formulation A) was evenly applied to the hair bundle and kneaded in for 30 seconds. (2) The above hair bundle was thoroughly washed with warm water at 40°C, and excess moisture was removed. (3) 0.5 g of the aromatic composition (formulation B) was evenly applied to the above hair bundle and kneaded in for 30 seconds respectively. (4) The above hair bundle was lightly washed with warm water at 40°C, excess moisture was removed, and it was dried at room temperature for 1 day. (5) Five fragrance expert monitors evaluated the fragrance of the above hair bundle according to the following five-level criteria. The average value of the five people was calculated, and the sensory evaluation result was obtained according to the following criteria. The results are shown in Table 3.

[0059] Sensory evaluation score 5: The fragrance is felt very clearly 4: The fragrance is felt well 3: The fragrance is felt 2: The fragrance is felt slightly 1: The fragrance is not felt

[0061] As shown in Table 3, when using an aromatic composition containing component (B-2) after using a pretreatment composition containing component (A), the fragrance persistence was good.

[0062] As shown in Table 3, when using an aromatic composition containing component (B-2) after using a pretreatment composition not containing component (A) (Comparative Example 3), or when using an aromatic composition not containing component (B-2) after using a pretreatment composition containing component (A) (Comparative Example 2), the fragrance was weak or not felt, and the aromaticity was weak and did not persist. When using an aromatic composition containing component (B-2) after using a pretreatment composition containing component (A) (Examples a, Examples 1 to 6), the aromaticity was strongly persistent. The aromaticity also strongly persisted for the test examples in which the types of component (B-1) and component (B-2) were changed (Examples 7 to 8, Examples 9 to 14).

[0063] The following shows formulation examples of the composition of the present invention. Formulation Examples 1 and 2 are formulation examples of the pretreatment composition, and Formulation Examples 3 to 7, 9 to 10 are formulation examples of the aromatic composition.

Industrial Applicability

[0074] According to the present invention, by using the above pretreatment composition on the skin or hair and then using the above aromatic composition, the aroma due to the lactone compound or monoterpene can be strongly and continuously maintained on the skin or hair for a long time as compared with the case of using the above aromatic composition alone. The combination of the above pretreatment composition and the aromatic composition can be appropriately selected according to the purpose, such as shampoo (pretreatment composition) and conditioner (aromatic composition), body wash (pretreatment composition) and antiperspirant (aromatic composition), etc., and thus can be applied to various uses.
