Embodiment

[0038] Hereinafter, the present invention will be described in further detail with reference to examples. However, the present invention is not limited to these Examples. Note that the amounts of each component listed in Tables 1-3 are % by weight.

[0039] 1. Evaluation of deodorants containing various surfactants

[0040]The components listed in Table 1 were added to deionized water corresponding to the amount of (C) aqueous solvent shown in Table 1 at room temperature. The mixture was stirred and deodorant was obtained without filtration. Each deodorant contains (A) zinc oxide, (B) organic acid and preservatives. The deodorant of Example 1 also contained betaine lauryldimethylglycinate, which is an amphoteric surfactant having a carboxylate group, as a surfactant. The deodorant of Example 2 further contained sodium lauryl diaminoethylglycinate, which is an amphoteric surfactant having a carboxyl group, as a surfactant. The deodorant of Comparative Example 2 further con...

Abstract

This deodorant contains (A) zinc oxide, (B) an organic acid, (C) an aqueous solvent and (D) an amphoteric surfactant having either a carboxylate group or a carboxy group.

Description

technical field [0001] This invention relates to deodorants. Background technique [0002] Generally, deodorants are used to reduce various odors generated in daily life, such as unpleasant odors caused by nitrogen compounds, sulfur compounds, short-chain fatty acids, and aldehydes. Furthermore, improvements in housing conditions in recent years, including greater airtightness, have made people more sensitive to unpleasant odors caused by, for example, chemical compounds from building materials. Therefore, there is a need for deodorants that can more effectively remove unpleasant odors. [0003] In addition, since deodorants may come into contact with the human body during use and be discarded after use, deodorants with low toxicity are required. [0004] JP 2001-190344A (hereinafter also referred to as "related art document") proposes a deodorant comprising zinc oxide and amino acid as a deodorant component and water as a solvent. In this deodorant, zinc oxide, which is ...
