The phenyl silicone oil, with its unique molecular structure, has initiated a technological revolution in the fields of antiperspirants and deodorants. Its high refractive index characteristic not only gives the product a natural luster, but also achieves dual functions by forming a breathable membrane with a 0.1-micron thickness: On one hand, the membrane layer can encapsulate ingredients such as chlorohydrin aluminum for antiperspirant purposes, extending the control sweat duration to 48 hours, while avoiding the irritation caused by direct contact of aluminum salts with the skin; on the other hand, the breathable membrane allows oxygen to freely pass through, maintaining the micro-ecological balance under the armpit and reducing the risk of redness and swelling. Experimental data shows that the antiperspirant with 5% phenyl silicone oil has a 37% reduction in the fluctuation range of skin pH value after use, and the residual rate after rinsing is less than 0.5%, completely solving the pain points of traditional products such as stickiness and false smoothness. 
In the anti-sweat and deodorant formula, the excellent compatibility between phenylsilicone oil and polar oils is crucial. It can significantly enhance the dispersion stability of chemical sunscreens, powders and silicone oil, increasing the sun protection factor (SPF) by 15% to 20%. For instance, an international brand's "24-hour long-lasting makeup-protecting and sweat-stopping spray" achieves the combined effects of controlling sweat, providing sun protection and preventing hyperpigmentation through the synergistic action of phenylsilicone oil and microencapsulated aluminum salts. Within its first month on the market, it occupied 32% of the Asia-Pacific market share. Moreover, its oxidation resistance property reduces the degradation rate of active ingredients after the product is opened to one-third of that of traditional formulas, making it an ideal choice for sports scenarios.
