Science
Mechanism of Action
This ingredient operates by delivering vital amino acids, which are integral for cellular restructuring and maintaining skin integrity. It also acts as a humectant, forming a delicate, moisture-retentive film on the stratum corneum, thereby preventing transepidermal water loss and sustaining optimal hydration. The inherent amphiphilic nature of its amino acids may additionally contribute to a mild cleansing effect by interacting with surface impurities.

Dusting Analysis
No data suggests that Hydrolyzed Lactalbumin is commonly 'dusted' or used misleadingly at sub-effective concentrations in formulations.
The Formula
Formulation
Stability
Lactalbumin hydrolysate maintains stability within a narrow pH range of 6.5-7.5. As a protein derivative, exposure to extreme pH values or elevated temperatures can induce denaturation, leading to a loss of efficacy.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Hydrolyzed Lactalbumin, along with other bovine milk proteins and their derivatives, is safe for cosmetic applications. Comprehensive studies indicated no significant ocular or dermal irritation, nor sensitization in animal or human subjects. The Panel determined that Type I sensitivity induction from cosmetic exposure to bovine milk proteins is highly improbable. The FDA further confirms these highly processed ingredients pose no risk of infectious agent transmission in cosmetic products.
