A Japanese personal care brand approached Elintree because they wanted to expand their product range and develop a new product line for the premium household market.

The customer was looking for a reusable household wipes solution that could provide better durability, cleaning performance, and a more sustainable user experience compared with traditional disposable wipes.

They needed an OEM partner who could support the whole development process, including material selection, product structure, formula adjustment, and packaging design.

Understanding the Product Requirements

For the Japanese market, the customer wanted the product to balance:

• Premium appearance
• Soft and comfortable touch
• Reusable performance
• Effective household cleaning ability

Based on these requirements, Elintree started the product development process.

Initial Product Development

The first sample was developed with:

• 40GSM spunlace nonwoven
• Plain pattern structure
• 35% viscose + 65% polyester blend

The material combination was selected to balance softness and durability:

• Viscose provides better softness and liquid absorption
• Polyester improves wet strength and durability during use

The packaging was designed with a minimalist premium style:

• White background with brand color elements
• Flip-top packaging for convenient repeated use
• Better sealing performance to maintain moisture after opening

Product Testing & Improvement

During sample evaluation, the customer was satisfied with the overall softness and daily cleaning experience.

However, after repeated washing tests, we identified areas that needed further improvement:

• The wipes maintained good performance after several washes
• After repeated washing, small fibers started appearing on the surface
• Cleaning performance, especially for oil stains, gradually decreased

Based on the test results, Elintree continued optimizing the material structure and formula.

Material Structure Upgrade

To improve durability and cleaning performance, we upgraded the material solution.

The improved product uses:

• 100GSM spunlace nonwoven
• Plain pattern structure
• Cross-lapping technology

Compared with the first version, the upgraded structure provides:

• Higher wet strength
• Better fiber stability after washing
• Improved liquid absorption
• Stronger cleaning performance for household use

The product was tested under repeated washing conditions and showed stable performance for long-term household reuse.

Formula Optimization for Better Cleaning Performance

To better match household cleaning needs, Elintree also optimized the liquid formula.

The upgraded formula added natural plant extracts:

The formula upgrade helps:

• Remove daily household stains
• Improve oil stain cleaning ability
• Provide a more pleasant cleaning experience

Final Product Solution

After optimization, the final product combined:

Material Performance

• 100GSM spunlace structure
• Stronger durability
• Better absorbency
• Improved washing performance

User Experience

• Soft touch
• Premium appearance
• Convenient flip-top packaging
• Suitable for repeated household use

Product Positioning

A premium reusable household wipes solution designed for consumers who value:

• Sustainability
• Quality
• Long-term usability

Project Outcome

Through multiple rounds of testing and adjustment, Elintree helped the customer transform an initial product concept into a market-ready reusable household wipes solution.

This project demonstrated Elintree's ability to support brands from:

Product Concept → Material Selection → Formula Development → Packaging Design → Mass Production
