Step 1
Brief review
Buyers send product category, target market, ingredient direction, texture preference, packaging idea, quantity and sample deadline.
A useful R&D brief for ROUSHUN shampoo, DR.DAVEY body lotion or shower gel should include target country, sales channel, capacity, preferred bottle, fragrance direction, label language and first sample deadline. For buyers comparing a China shower gel factory, foam feel, viscosity, fragrance and bottle size should be included from the first message.
Example: ROUSHUN shower gel 1000ml for distributor channel, fresh fragrance, pump bottle, first sample needed before carton planning.
Step 2
Formula and packaging direction
The team checks whether the request fits a standard formula path, a custom development path or a packaging-first private label project.
ROUSHUN LAB can focus on shampoo, conditioner and shower gel feel; DR.DAVEY LAB can focus on lotion, serum, cream and body oil texture; King Metis LAB coordinates whether the product should start from an existing reference, a revised sample or a new private label direction.
Example: DR.DAVEY lotion 500ml with moisturizing texture, pump bottle, carton reference and document support where applicable.
Step 3
Sample preparation
Samples are prepared for review of texture, fragrance, color, foam, rinse feel, bottle compatibility and product presentation.
Sample preparation should not only check the formula. Buyers should also review whether the product works with the selected bottle, pump, cap, label size and carton direction. For shower gel, the sample review should include foam, rinse feel and fragrance retention; for lotion, it should include spreadability, absorption feel and pump compatibility.
Example: compare one shower gel sample, one body lotion sample and one shampoo sample together when planning a multi-SKU product family.
Step 4
Revision and approval
Buyer feedback is turned into a revision list before final sample approval, quotation and production planning.
The revision list should be practical: texture too thick or too thin, fragrance too strong or too light, bottle capacity change, carton direction, label language, sample quantity and target launch timing. After approval, King Metis can connect the sample direction to quotation, production lead time and document discussion.
Example: revise fragrance and viscosity first, then confirm label size, carton style, MOQ and final RFQ details.
