This is a product profile, not a new product announcement, performance ranking, or firsthand test report. On September 28, 2026, the protected product record was confirmed, and the EPHYONyun Sensory Underwear Bubble Mousse is in stock, with a public specification of 300g/bottle and a liquid dosage form; the current detail images show the foam pump head and hand washing process.

The current detailed illustration shows a four-step usage sequence: first, put the clothing into water to wet it; then apply an appropriate amount of product to the stains and let it sit for 3 to 5 minutes; rub evenly by hand for 2 to 3 minutes while it is half-wet; finally, rinse thoroughly with clean water. This article expresses the complete process accordingly and does not treat 'foam mousse' as a product that allows skipping rinsing.

The detailed images and packaging also feature promotional words such as 'sterilization rate,' 'pH,' 'no fluorescent agents,' 'no phosphorus,' and 'no bleaching,' but the currently disclosed product records do not include supporting inspection reports, testing conditions, or label version explanations that can be publicly verified. This document does not treat these words as hard facts, nor does it extend claims of hypoallergenic properties, suitability for children, intimate health, or no-rinse requirements based on them.

Before starting to wash, first check the garment care label. GINETEX explains that care information reflects the maximum treatment intensity the fabric can withstand, and it is also necessary to consider sensitive parts such as dyeing, finishing, buttons, zippers, and decorations. Although underwear is small in size, the tolerance of fabrics, straps, underwires, lace, prints, and elastic components may vary, so it cannot be treated uniformly just by the 'underwear' category.

The FTC's care label rules also emphasize that labels should indicate hand wash or machine wash, temperature, drying, and necessary warnings, and that the care information should have a reasonable basis. It describes hand washing as the process of using water and detergent and gently squeezing, while defining thorough rinsing as removing detergent, soap, or bleach multiple times. The care principles are cited here, without directly treating U.S. rules as regulations for the Chinese market.

If the clothing label states that it can only be hand washed, do not switch to machine washing just because the product is a foam type; if the label indicates it cannot be washed with water or requires professional care, you also cannot replace it with spot foam treatment on your own. Woolmark's public guidance on wool similarly requires following the care label first and, when hand washing is allowed, using a gentle detergent, rinsing thoroughly, and drying appropriately.

Stain treatment should be limited to the washing range allowed by the garment's label. According to the current detailed instructions, first moisten the area before applying; do not extend the resting or rubbing time, and do not use brushes, hot water, or additional detergents to 'enhance' the effect. For light and dark colors, easily faded items, or garments with prints or decorations, test on an inconspicuous area first; stop if discoloration, pilling, or structural distortion occurs.

After rinsing with clean water, dehydration and drying should still follow the garment label. Clothes with underwire or molded cups should not be forced to remove water by twisting; whether they can be dehydrated, hung, laid flat, or tumble dried should be based on the specific garment instructions. The steps for using detergent cannot replace the subsequent care requirements provided by the fabric and garment manufacturers.

Safety boundaries are equally important. The American Cleaning Association recommends reading the full labels and warnings before using laundry products, keeping the original packaging, not mixing with other household cleaners, and storing them immediately after use, out of reach of children and pets. The pump structure makes it convenient to use, but it does not mean that children can operate it or that the product can be transferred to unlabeled containers.

The verifiable facts about EPHYON in this file are the currently available 300g liquid cloud-sensing lingerie mousse, foam pump heads, and the steps clearly shown in the current detail images: moistening, applying, resting, rubbing, and rinsing with clean water. This article does not claim that the product is suitable for all lingerie materials, nor does it make any claims about sterilization, hypoallergenic, no-rinse, or comparative effects.

Applicable Scope: The current complete label on the physical item in hand takes precedence over the webpage overview; if there is a conflict between the physical label, webpage images, or garment care instructions, usage should be paused and confirmed with the product provider or clothing brand. All times, dosages, temperatures, rinsing, and drying methods must not exceed the explicit instructions.
