1. Etiology of Diaper Dermatitis

Infant diaper dermatitis (diaper rash) is triggered by the prolonged contact of skin with fecal enzymes (protease and lipase) and ammonia produced by bacterial urea hydrolysis. This raises skin pH from its healthy acidic state (5.5) to an alkaline 7.5-8.0, dissolving the epidermal stratum corneum barrier and enabling rapid colonization by Candida albicans and Staphylococcus aureus.

2. Patented Micro-Encapsulation Delivery System

The Susan Mammy flagship diaper series incorporates patented German micro-encapsulation technology. Lyophilized live strains of beneficial Lactobacillus rhamnosus and Bifidobacterium lactis are encapsulated in moisture-soluble lipid polymers embedded into the sub-topsheet distribution layer.

3. Biological Activation Cascade

Upon urination, body heat (36.5°C-37°C) and moisture dissolve the capsule outer shell within 12 seconds, releasing millions of active CFU probiotics. These friendly bacteria metabolize simple carbohydrates to produce natural lactic acid, neutralizing ammonia on contact and stabilizing cutaneous micro-environment pH at exactly 5.5.

Certified clinical microbiological testing demonstrates a 99.2% antibacterial inhibition rate, significantly outperforming conventional zinc oxide chemical barrier creams.
