No. 111 is Bath Salt . Bath salt is a bath preparation that dissolves water-soluble salts such as magnesium sulfate and sodium chloride in bathwater to provide a bathing sensation, fragrance, and a soft feel on the skin. Although it is less greasy and leaves less of an oil film in the bath than No. 110 Bath Oil, its key features are complete dissolution rather than the skin's moisturizing film, a change in the sensation of the water, and a clean finish after bathing .
The mere fact that magnesium salts are included does not imply magnesium replenishment in the body or therapeutic effects for muscle pain. This product is defined as a cosmetic bath soak, not a medicinal mineral therapy.
The target consumers are those who want to make bathing a simple home spa routine but do not want the greasiness of bath oils or the slipperiness of the bathtub. It also includes demand for bathing after hotels, resorts, or fitness centers, as well as for gifting.
The main reasons for purchase are as follows.
- Simple single-use bath product that is easy to put in water
- A soft and clean bath sensation provided without an oil film
- A sensory bathing experience utilizing scent, color, and minerals
- Convenience of disposable pouches for travel and hotel use
- A product that reduces the burden of cleaning the bathtub after bathing
Buyers should prioritize the dissolution rate, bottom residue, skin and mucous membrane irritation, and hygroscopic and solidification stability over the origin or rarity of salts .
The global bath salt market is segmented into bulk Epsom salt, scented mineral salt, magnesium bath soak, and high-end botanical bath powder. Dr. Teal's offers bulk Epsom salts such as fragrance-free and lavender varieties, Kneipp combines rock salt with herbal scents, and Herbivore features magnesium and botanical themes.
The key targets are households with bathtubs, fitness and wellness consumers, and the hotel, resort, and gift markets. However, due to the heavy product weight and low technological barriers to entry, local distribution, hotel B2B, and high-value small packaging may be more advantageous than global D2C exports.
Key performance characteristics include rapid and complete dissolution in water, uniform fragrance and color expression, low residue, and a comfortable feel on the skin. The basic salts include magnesium sulfate, sea salt, rock salt, and sodium bicarbonate, while fragrances, plant powders, and moisturizing powders are applied optionally.
Formula Route | Design direction | Buyer's judgment |
|---|---|---|
| A. Fragrance-Free Mineral Soak — Hero | Centered on refined magnesium sulfate and sea salt, excluding flavors, colors, and plant fragments | Most advantageous for sensitive skin, hotel use, and NoChemiLife application, as well as for complete dissolution. |
| B.Low-Aroma Mineral Bath Salt | Application of reviewed low-intensity fragrance and uniform coating technology | High sensory appeal and gift value, but requires management of allergen and fragrance variations. |
| C. Botanical Spa Bath Soak | Enhances visual appeal and moisturization with plant powder, flower petals, oil, or milk powder | High premium value, but be careful of residue, drainage, microorganisms, and bathtub contamination. |
Hero Route minimizes the number of ingredients and manages particle size and purity to ensure they dissolve cleanly in water. Real flower petals and herb pieces can cause drain clogging and increase the burden of bathtub cleaning, outweighing any visual effect.
Although bath salts are diluted with water, they come into contact with the skin, eyes, and mucous membranes of the entire body. Excessively high salt concentrations or the presence of undissolved crystals can cause skin irritation and friction. Allergens in fragrances, essential oils, dyes, and plant powders, as well as impurities in the raw materials, must also be reviewed.

The U.S. FDA includes bath oils, tablets, and salts in the category of bath preparation cosmetics. U.S. FDA Cosmetic Product Classification
Magnesium absorption, muscle pain relief, toxin elimination, and insomnia improvement are excluded from basic cosmetic SKUs. If fragrance or color is included, not only skin safety but also bath discoloration and residue are verified under actual bath dilution conditions.
The recommended specification is a 50–80g single-use high-barrier pouch . It requires no weighing and is suitable for hotels, travel, and experiential sales. For home use, a 500–1,000g resealable pouch or jar may be used, but care must be taken to prevent repeated moisture ingress.
Bath salts can solidify and their scent and color may become uneven if they absorb moisture. The shelf life is determined by moisture-proof packaging, high-temperature and high-humidity stability, scent retention, and pouch sealing. Since the product price is low relative to its weight, overseas shipping costs, pouch damage, and powder leakage also directly affect business viability.
The recommended position is Clean Single-Dose Mineral Bath Soak . Rather than competing with large-volume raw Epsom salts, it sells refined ingredients, complete dissolution, and the convenience of single-use.
- Medium-sized large-capacity bath salt: Approx. US$8–18 per 1–2 kg
- Scented bath salt: Approx. US$15–30 per 500–850g
- Premium mineral/botanical soak: Approx. US$30–60 per 300–500g
- Single serving for hotels/travel: Approx. US$2–6 based on 50–80g
In global D2C, shipping costs are high, so 3- to 5-time gift sets, hotel amenities, and private labels for local distribution are more advantageous than single large-volume products.

The competitiveness of K-Beauty lies in small-package designs and the combination of Korean sea salt, hot spring, and herb stories with travel and hotel amenities. For NoChemiLife Hero, a Fragrance-Free Mineral Bath Soak is suitable, as it excludes artificial fragrances, dyes, and plant extracts, and verifies the purity and complete solubility of the ingredients.

Buyer RFQ includes the country of sale, consumer, hotel, and SPA channels, types and origins of salts, Formula Route, single-use amount and packaging, fragrance, color, essential oil, and botanical policies, comparison products, bath conditions, test scope, and initial and annual quantities.
The key to determining commercialization is as follows.
- Does the standard usage dissolve quickly in bathtub water and leave no bottom crystals or plant residue?
- Are skin, eye, and mucous membrane irritations, as well as bathtub discoloration and drainage issues, managed?
- Is there minimal freezing, fragrance deterioration, or pouch leakage even after distribution in high temperature and humidity?
- Can low technological barriers and high international shipping costs be overcome with a hotel and small package model?
Although the manufacturing of bath salts appears simple, the purity of the raw materials and the moisture resistance of the packaging determine the quality. The conditions for success are not excessive mineral efficacy, but complete dissolution, a clean bath, and a single-use experience that requires no measurement .
