Embodiment 1

[0031] The formula of the emulsion deodorant in the present embodiment is as follows: (weight %)

[0032] A. Constituting the oil phase part:

[0033] Emulsifier: polyoxyethylene (2) stearyl ether 3%

[0034] Polyoxyethylene (21) stearyl ether 2%

[0035] Dispersed Phase: Isohexadecane 10%

[0036] Cyclomethicone and Polypropylene Glycol (15) Stearyl Ether 8%

[0037] B. Constituting the water phase part:

[0038] Emollient: polyoxyl hexacene (30) sorbitan ether 4.0%

[0039] Thickener: xanthan gum 0.2%

[0040] Antiseptic: Methylparaben 0.3%

[0041] Propylparaben 0.5%

[0042] Moisturizer: Squalane 5.0%

[0043] Solvent deionized water: the balance, the weight ratio with the above-mentioned emulsified oil phase is: emulsified oil phase: water=1:5;

[0044] C. Deodorant actives fraction:

[0045] Nano Zinc Oxide Glycerin Dispersion 7.0%

[0046] D. Additive part:

[0047] Antibacterial agent: Sodium N-lauroylorganate plus 0.05%

[0048] Fr...

Embodiment 2

[0058] The preparation steps of this example are exactly the same as those of the above-mentioned Example 1, the difference is: ① In the part B that constitutes the water phase, glycerin is used as the moisturizing agent instead of squalane; ② In the third step of the preparation step, a water bath is used The heating temperature was 70°C. Finally, an emulsion deodorant is produced.

[0059] The emulsion deodorant prepared in this example has slightly poor rollability and relatively high viscosity, but has a good deodorizing effect at room temperature. After high temperature and low temperature stability test, its stability performance is good without delamination. Good touch to the skin, no special irritation.

Embodiment 3

[0061] This embodiment is proposed as a comparative test of the comparative example.

[0062] The preparation steps of this embodiment are basically the same as the above-mentioned embodiment 1.

[0063] The difference is: ① The emulsifier in part A uses polyoxyethylene (2) stearyl ether, the dosage is 5%; ② in part B, the moisturizing agent uses glycerin instead of squalane; ③ deodorant In the active material part C, the nano-zinc oxide is not ground together with glycerin to form a dispersion, but the nano-zinc oxide is directly added to the oil phase to disperse in the oil phase, and then added to the water phase for emulsification. ④ In the third step of the preparation step, the heating temperature in a water bath is 70°C.

[0064] The emulsion deodorant prepared in the comparative example of this embodiment has a poor form, and fine granular substances can be seen on the surface of the product. The emulsion deodorant composition has stable performance at normal temperat...

Abstract

The invention discloses an emulsion deodorant and its preparation process, wherein the composition comprises nano zinc oxide as the main deodorizing active compounds, an oily phase portion including emulsifying agent and grease discontinuous phase, an aqueous phase portion including emollient, thickening agent, preservative agent, humectant and solvent deionized water, as well as a small amount of addition agents such as antibacterial agent and condiment.

Description

field of invention [0001] The invention relates to an emulsion deodorant, which is an emulsion composition with nano-zinc oxide as the main deodorant active substance; in particular, it relates to an oil / water type deodorant composition and its preparation method. It belongs to the technical field of preparation of cosmetic and skin care chemical preparations. Background of the invention [0002] It is generally believed that human body odor is caused in part by irritating fatty acid compounds produced by the interaction of microorganisms with sweat gland secretions, and one method of controlling this odor, in addition to washing, is the topical application of deodorant compositions on the body. [0003] Deodorants are preparations that are used to mask odors or to prevent the development of odors by reducing the local microbial population. In the deodorant market, products based on aluminum salts or zirconium salts are dominant. These products are used to prevent or contr...
