Odor elimination and environmental cleanup are important tasks that are urgently needed in daily life. It is a known fact that feasts have been used to mask unpleasant odors and body scents since similarities. Deodorization, deodorization, deodorization, and the like have been achieved by physical methods (absorption, adsorption, coating) and biological methods (sterilization, microorganisms, enzyme treatment).

In general, masking means enclosing odors using aromatic components, and it has been called to include odor neutralization and deodorization by chemical change. However, masking in the present invention turns out to be not odor due to odor neutralization or chemical change. The odor can be interpreted as meaning that the fragrance ingredients are surrounded. Odor masking by fragrance is performed by the following method. First, the odor physiological stimulus is changed by adding an aromatic component having a threshold value smaller than that of the odor component. Second, by using a perfume that has a stronger physiological stimulation than the odor component, it reduces the sense corresponding to the odor. Third, by using a fragrance having a high vapor pressure compared to the malodorous component to change the "nature of the fragrance", that is, to change the overall vapor component, and to reduce the vapor partial pressure of the malodor.

Generally, sunscreens are formulated with "ultraviolet blockers" to prevent UV penetration. These sunscreens use inorganic materials, such as titanium dioxide, and UV-scatters that prevent UV from penetrating into the skin by physical scattering, and organic materials such as octyl di-methyl PABA. There is a UV absorber that absorbs ultraviolet light by the chemical method to extinguish it.

Normally, sunscreens contain not only the above-mentioned UV light scattering agents but also UV absorbers. Because UV scattering agent has a limit that can scatter, organic sunscreen is used in parallel. These UV scattering agents have excellent blocking effect and have no side effects such as contact dermatitis, but because they are opaque, they have a disadvantage in that they are mixed with creams or lotions. Or an unpleasant odor occurs.

In order to solve this problem of raw material odor, fragrance is generally used, but the fragrance is easily volatilized in nature, so it is difficult to maintain it for a long time and it does not show enough effect in actual use due to deviation in sunscreen manufacturing process and prolonged shelf life. Is often there.

Therefore, the present invention, by adding a masking fragrance to the sunscreen base to cover the smell of the sunscreen base in the manufacturing process or use, to reduce the problems caused by the weakening of the fragrance and to provide a good fragrance to the consumer to give the sunscreen material more emotionally There is a need to provide a fragrance composition for sunscreen base masking and a sunscreen base composition comprising the same.
