Sodium palm kernelate is the sodium salt of palm kernel fatty acids. It doesn't have a single, specific chemical formula because palm kernel oil is a mixture of various fatty acids. However, we can represent it as:

C₁₅H₃₁COONa

This is a general representation of the sodium salt of a typical fatty acid found in palm kernel oil, with a 15-carbon chain. It's important to remember that this is a simplification and the actual composition of sodium palm kernelate varies depending on the source and processing methods.
