Name

Caprylhydroxamic Acid

Has some considerations

Description

Caprylhydroxamic acid is used as a chelating agent and preservative in cosmetics. This means it helps prevent minerals in water from reacting with soaps or other ingredients to form soap scum or other undesirable compounds. Caprylhydroxamic acid is made by reacting either methyl caprylate or ethyl caprylate with hydroxylamine through transamidation process to form ethyl acetate. Caprylhydroxamic acid is then isolated and purified via recrystallization.

Benefits

Helps prevent soap scum formation. NOT found to be a mutagen or teratogen.

Considerations

• Contamination Concerns In very high or very low pH conditions (below 5 or above 8), it can break down and form hydroxylamine, which is toxic. However, most cosmetic items would not have these pH extremes necessary for this to happen. • Skin Irritation May cause mild skin irritation or skin sensitization at higher concentrations.
