Embodiment 1～10、 comparative example 1～6

[0087] Non-aqueous antiperspirant and deodorant stick compositions of the compositions shown in Table 1 and Table 2 were manufactured, and evaluated for dry feeling, stickiness, smoothness and white residue. The results are shown together in Table 1 and Table 2.

[0088] (preparation method)

[0089] Mix higher alcohol, wax, volatile oil agent, non-volatile oil agent, higher alcohol and wax are heated and stirred at melting temperature (about 80° C.) to form a single liquid phase. Keep at a temperature slightly higher than the freezing point of the system (about 65°C), add the remaining components other than component (D) while stirring, and then add component (D). After fully stirring, flow into the container and solidify at room temperature.

[0090] (Evaluation method)

[0091] (1) Three specialized participants applied an appropriate amount of each bar evenly to the wrists, and sensory evaluation of dryness, stickiness, and smoothness based on the following criteria. T...

Abstract

An anhydrous antiperspirant / deodorant stick composition containing the following ingredients (A), (B), (C) and (D): (A) from 15 to 30 wt % of a higher alcohol having from 12 to carbon atoms, (B) a polypropylene glycol having an average molecular weight from 400 to 2,000, (C) a volatile cosmetic oil, and (D) an antiperspirant agent or deodorant agent.

Description

technical field [0001] The present invention relates to non-aqueous antiperspirant and deodorant compositions in stick form. Background technique [0002] Stick-type antiperspirant deodorants are widely used, and aluminum salts, zirconium salts, higher alcohols, volatile silicones, and the like are generally combined. However, such antiperspirant and deodorant sticks cannot satisfy the feeling of use, and attempts have been made to improve the effect of antiperspirant and deodorant and to improve the feeling of use. [0003] For example, in US Pat. No. 4,725,432, a long-chain fatty alcohol having 20 or more carbon atoms is used to improve the hardness of a solid stick. In addition, in US Pat. No. 5,932,199, an attempt is made to improve the feeling of use by using a fragrance carrier material and blending a paste containing a moisturizing agent such as glycerin. [0004] However, a more excellent antiperspirant and deodorant stick composition has been desired in terms of u...
