What Stearamide AMP does

Thickens the water and oil mix
Helps keep the formula blended
Adds a smooth, soft feel

Stearamide AMP is made by joining stearic acid with AMP, a small molecule also used to adjust pH in many formulas. Stearic acid is a common fatty acid found in plant and animal fats, so its starting materials are familiar to most formulators. The result is a waxy solid that melts with gentle heat and sets as a formula cools.

In lotion, formulators use it mainly for texture. It adds body, helps keep the oil and water parts of a formula blended, and leaves a smooth feel on the skin. As a fatty compound, it also helps soften the skin's surface. Its feel is cushioned rather than sticky.

Good for

Suits body lotions and creams that need a smooth texture and a stable blend of oil and water.

Frequently asked questions

Is Stearamide AMP safe for sensitive skin?

It is commonly found in body lotions and is generally well tolerated. Like any ingredient, it can bother a person with a specific sensitivity, so check the full label and patch test if your skin reacts easily.

Is Stearamide AMP the same as stearic acid?

No. Stearic acid is one of the two starting ingredients. Stearamide AMP is a separate compound formed when stearic acid joins with AMP. Because the chemistry changes, the two can behave differently in a formula.
