What Hydrogenated Vegetable Oil does

Firms up and thickens formulas
Adds slip and a smooth glide
Helps stop the oil from going rancid
Softens the feel of hair and skin

Hydrogenated vegetable oil starts as a plant oil, such as soybean or canola. Under heat, pressure and a metal catalyst, hydrogen is added to some double bonds in its fatty acids. That turns a liquid oil into a firmer fat.

Formulators use it to add body and structure. In shampoo it helps build a creamy texture and smooth feel. In lip care it helps balms hold their shape and glide easily. Its more saturated fats also resist going rancid, so products keep their feel longer.

Good for

Suits shampoos and lip care that need a firm, stable texture and a smooth glide across lips and hair.

Frequently asked questions

Is hydrogenated vegetable oil the same as trans fat?

Not quite. Trans fats are a food nutrition concern, and the word can sound alarming. In skin and hair products the oil is used for texture, not eaten. Lip balm is the one place a little may be swallowed.

Does hydrogenated vegetable oil feel heavy on oily skin?

It is a rich fat, so it can feel heavy on very oily or acne-prone skin. Try a lighter formula if it feels too heavy, and patch test new products first.
