Beyond the soap cherished by elders, modern options like scented soaps, body washes, bath salts, and bubble baths are readily available. Each product varies in ingredients and properties, making selection a nuanced choice.
Body washes may cause allergies
Body washes are chemically synthesized detergents containing 15%-35% surfactants.35%, plus detergent aids like phosphates, sodium carbonate, fragrances, and enzymes, along with foam boosters, stabilizers, thickeners, and complexing agents.
High-quality shower gels produce rich, stable lather, are gentle on skin and eyes, effectively cleanse without drying, and are popular among younger users.
Compared to soap, bath liquids have weaker degreasing power, though some individuals may develop allergies to certain additives. Rinse off promptly with bath liquid Most soaps and bath liquids are alkaline, while human skin is neutral to slightly acidic. Using appropriate bathing products during showers helps remove oils and dead skin cells, leaving a refreshing, comfortable sensation.However, these products also strip away natural sebum while cleansing, potentially causing dryness, tightness, or even itching. Skin possesses its own pH-balancing mechanisms, so mildly alkaline products generally pose no harm, with any temporary discomfort subsiding shortly after bathing.Frequent bathing or prolonged use of overly alkaline products, however, can damage the skin's protective barrier, accelerating moisture loss. This not only causes dryness and itching but may also lead to excessive keratinization of hair follicles. Therefore, unless skin is excessively oily, neutral-pH bath liquids and soaps are preferable. Highly alkaline products can irritate the skin and trigger allergic dermatitis.During use, minimize the time bath products remain on the skin and rinse off foam promptly.
Avoid Storing Bath Products for Extended Periods
Additionally, choose bath products with minimal fragrances or dyes to prevent prolonged skin exposure that could heighten sensitivity to UV rays. Unsaturated fatty acids in soap oxidize and rancidify easily, making prolonged storage inadvisable.
Avoid soap
Soap is arguably the most traditional bathing product in China. Made from animal and plant fats through chemical reactions, it is a higher fatty acid salt primarily composed of sodium stearate.Some soaps also contain water softeners like sodium phosphate, sodium carbonate, and sodium silicate, making them highly alkaline. This alkalinity can irritate skin and mucous membranes—for instance, soapy water splashed into the eyes causes pain, light sensitivity, and tearing. Thus, soap is better suited for laundry and should be minimized for bathing.
Particularly problematic is soap's tendency to irritate the urethra and vaginal mucosa, causing burning pain. Therefore, soap or body wash should never be used to wash a daughter's lower body. Women of all ages should also avoid such products. Under normal circumstances, clean water suffices for washing. If discomfort occurs, consult a doctor and follow medical guidance.
