Hydrolyzed Sponge are based on its biological origin, chemical hydrolysis process, micro-/nano-structure, and physicochemical interactions with tissues or environments.
1. Biological and Structural Basis
Hydrolyzed Sponge is typically derived from marine sponges, which possess a natural skeletal system composed mainly of siliceous spicules and collagen-like proteins.
Key structural features:
- Microneedle-like spicules (silica-based)
- Highly porous, three-dimensional structure
- Large surface area
Scientific principle:
The sponge’s natural microstructure enables mechanical stimulation, adsorption, and controlled delivery when hydrolyzed and processed into fine particles.
2. Hydrolysis Mechanism
What hydrolysis does:
- Breaks down large sponge proteins and matrices into low-molecular-weight fragments
- Improves dispersion, bioavailability, and compatibility with formulations
Scientific principle:
Hydrolysis uses chemical (acid/alkali) or enzymatic cleavage of peptide bonds, transforming insoluble macromolecules into water-dispersible functional components.
3. Transdermal Penetration Enhancement
One of the most important principles, especially in cosmetic science.
Mechanism:
- Micro-spicules create temporary micro-channels in the stratum corneum
- Stimulate local microcirculation
- Enhance permeability without permanent tissue damage
Scientific principle:
This follows mechanical transdermal delivery theory, where physical micro-disruption reduces skin barrier resistance, increasing diffusion of active ingredients (Fick’s law of diffusion).
4. Biostimulation and Cell Response
Hydrolyzed Sponge can trigger biological responses in skin cells.
Cellular effects:
- Activates fibroblast proliferation
- Promotes collagen and elastin synthesis
- Enhances cellular metabolism
Scientific principle:
Mild, controlled mechanical stress induces a wound-healing cascade, activating growth factors such as TGF-β and stimulating extracellular matrix remodeling.
5. Adsorption and Carrier Function
Due to its porous structure, Hydrolyzed Sponge acts as a functional carrier.
Capabilities:
- Adsorbs sebum, impurities, and toxins
- Binds and stabilizes active ingredients
- Enables gradual release
Scientific principle:
Based on physical adsorption, van der Waals forces, and capillary action within micro-pores.
6. Biocompatibility and Biodegradability
Material characteristics:
- Naturally derived
- Non-synthetic
- Biodegradable
Scientific principle:
Protein-based and silica-based components are recognized by biological systems, minimizing immunogenicity and allowing enzymatic degradation over time.
7. Exfoliation and Renewal Dynamics
Hydrolyzed Sponge provides controlled exfoliation.
Mechanism:
- Removes corneocytes
- Accelerates epidermal turnover
- Improves skin texture
Scientific principle:
Combines mechanical exfoliation with biochemical signaling, leading to faster keratinocyte renewal.
8. Safety and Dose-Response Principle
- Effects depend on particle size, concentration, and exposure time
- Overuse may cause irritation due to excessive mechanical action
Scientific principle:
Follows dose-response theory, where optimal stimulation yields benefits, while excessive stimulation may cause adverse reactions.
