Why do candles drip less than they used to?

Question

It’s harder and harder to find drippy candles nowadays, most are drip-less. Is it cheaper to produce these? Is it a safety thing?

I’m writing this from the UK if that helps, as it might not be universal.

Answer 1

Even with regular wax, if a candles size (diameter) is correct for the size wick used, the candle will consume all of the available wax as the wick is consumed. That way there is no excess of wax to drip.
