Refined coconut oil 6501-98% (Ninol) is a high-purity nonionic surfactant with an active content of ≥98%. Its usage method is relatively simple, with the core principle being to add it in the later stage of formulation preparation. This is because 6501, as a co-surfactant, mainly serves to thicken, stabilize foam, and provide synergistic effects. Adding it too early may cause unnecessary competitive reactions with other raw materials. After addition, stir thoroughly to ensure uniform dispersion or dissolution in the system.
In practice, it is recommended to control the system temperature between 40~60°C when adding 6501, as the product has better fluidity at this range, making it easier to mix evenly. If the formulation is a cold-process system, it can also be added slowly at room temperature with extended stirring time. 6501 has excellent compatibility with anionic surfactants (e.g., AES, LAS), amphoteric surfactants (e.g., CAB), and other nonionic surfactants. Through synergistic effects, it can significantly improve the system's viscosity and foam stability.
Dosage varies greatly by application area: in personal care products (e.g., shampoo, body wash), the recommended dosage is typically 1%~5% to achieve ideal thickening and foam stabilization; in household detergents (e.g., dishwashing liquid), the dosage is generally 2%~8%, effectively improving degreasing ability and foam persistence; in industrial cleaners, it can be added at 1%~10% depending on formulation requirements. Before use, always conduct small-scale compatibility tests to ensure no precipitation, turbidity, or layering occurs with other components.

Personal Care Products: Add 1%~3% in shampoos, 1.5%~4% in body washes, 1%~3% in hand soaps, and 0.5%~2% in facial cleansers to achieve fine, dense, long-lasting foam while reducing formulation irritation.
Household Detergents: Add 3%~6% in dishwashing liquids to significantly enhance degreasing ability; add 2%~5% in liquid laundry detergents to effectively thicken at low active levels.
Industrial Cleaning and Textile Auxiliaries: Add 3%~10% in heavy-duty industrial cleaners as an emulsifying dispersant and viscosity regulator; add 2%~8% in textile scouring agents and detergents to help remove impurities and improve color fastness.
For all applications, it is recommended to determine the optimal dosage through gradient experiments to achieve ideal balance of thickening, foam stabilization, and cost.
