Butylene glycol in skincare
Is 1,4 butanediol used in skincare or only the 1,3 butanediol isomer? Is the method of producing 1,3 butanediol very different from producing the 1,4 isomer?

1,3 is used. “Butylene glycol is prepared by catalytic hydrogenation of aldol in the presence of hydrogen and a hydrogenation catalyst.”
1,4 is for industrial purposes or for recreational drug abuse…I won’t ask why you are asking

I was asking because I was aware that 1,4 butanediol is also used for recreational drug abuse; I was trying to avoid this and buy the 1,3 butanediol only. I was also curious whether, during production of 1,3 butanediol, the 1,4 butanediol is an isomer ”byproduct”. Is this the case?
