Science
Mechanism of Action
This ingredient reduces surface tension, facilitating effective cleansing and foam generation. It also acts as a conditioning agent by interacting with the skin and hair, potentially forming a protective film that enhances their softness and appearance.

Stability
Optimal resolubilization of alpha-lactalbumin, a component of lactalbumin, is observed between pH 6.5 and 7.0, with high levels of resolubilization extending up to pH 10.0. Alpha-lactalbumin also demonstrates relative heat stability post-drying across neutral (6.7) and acidic (4.3, 4.6) pH values. For optimal stability in emulsions, it is recommended to incorporate this ingredient into the oil phase and utilize additional thickeners and co-emulsifiers, as it does not possess inherent thickening properties.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated Sodium Stearoyl Lactalbumin. However, the CIR has reviewed similar 'Alkyl Lactyl Lactate Salts,' including Sodium Stearoyl Lactylate, concluding they are safe for cosmetic use when formulated to be non-irritating and non-sensitizing. The FDA generally does not pre-approve cosmetic ingredients but considers milk or processed milk ingredients not to be risk materials for the transmission of infectious agents in cosmetic products (21 CFR §700.27).
