Trans fats, when eaten, increases one's risk of coronary heart disease by raising LDL ("bad") cholesterol and lowering HDL or "good" cholesterol.

In order to emulsify the oils and other ingredients with water, companies should hydrogenate instead of using synthetic emulsifiers such as PEG, which also have very negative health effects. During this process, companies should ensure that the oil is completely hydrogenated so that NO TRANS FATS are produced. Hence hydrogenated oils in products will not affect levels of LDL or HDL if consumed.

Most hydrogenated oils reviewed on the Skin Deep database have a safety ranking of 0 (low hazard).
