What Is Capryloyl Pea Amino Acids?
Capryloyl Pea Amino Acids is a plant-derived ingredient created by joining octanoyl chloride, a fatty acid derivative, with the naturally occurring amino acids found in peas. The result is a gentle surface-active molecule that combines the nourishing traits of pea protein with the softening feel of a lightweight oil. Pea proteins have been used for decades in hair and skin care as mild alternatives to animal proteins, and chemists later discovered that attaching a short-chain fatty acid like caprylic acid could improve their spreadability and conditioning power. The manufacturing process starts by hydrolyzing pea protein into individual amino acids, then reacting them with octanoyl chloride under carefully controlled temperatures and pH. After purification and drying the final powder or fluid is ready for formulation.
You will most often find Capryloyl Pea Amino Acids in rinse-off and leave-on conditioners, shampoos, co-wash products, hair masks, curl-defining creams, facial cleansers, lightweight moisturizers, after-shave balms, anti-aging lotions and soothing masks geared toward sensitive skin.

Comedogenic Rating
Rating: 1 out of 5
Capryloyl Pea Amino Acids is primarily water soluble and forms an ultra thin breathable film rather than a heavy waxy layer. The short caprylic chain adds a touch of emollience but is not long enough to trap large amounts of oil or debris in pores. Most finished formulas use it at low to moderate percentages so buildup is unlikely. Because of this minimal occlusive behavior the ingredient is considered suitable for people prone to acne or breakouts.
