How to dequeue script on woocommerce product?

I’m trying to dequeue some scripts on woocommerce product, but for some reason I can’t find a way to check for a single product.

is_singular('product') doesn’t work for some reason. The dequeue itself works without the checks, e.g.:

add_action( 'wp_enqueue_scripts', 'my_custom_scripts', 100 );
function my_custom_scripts()
{
    wp_deregister_script( 'wp-mediaelement' );
    wp_deregister_style( 'wp-mediaelement' );
}
