Pet Skin Comfort Gel — Product Development Playbook
The problem this playbook solves: pet skin comfort after procedures and hotspots runs on generic antiseptics — a documented EV comfort gel for the clinic channel is the entry product the category lacks.
01 · The problem
Post-procedure and hotspot care in pets runs on generic antiseptics and cone-of-shame patience. The clinic-channel entry product the category lacks is a documented comfort gel: characterized EV material in a lick-tolerant base, positioned for post-procedure skin comfort under veterinary guidance — the single-program entry before platform expansion.
02 · Scientific rationale
Topical EV application for skin comfort is the most published corner of the EV literature (2026 systematic review of 19 human studies [3]; transposing it to companion animals is a formulation and regulatory exercise, not new science.). The gel base is fragrance-free and formulated to tolerate incidental licking; COAs carry microbial and endotoxin panels for veterinary use.
03 · Program documentation
Program documentation follows TONGNIAN's internal veterinary-protocol files; the human topical evidence base (systematic review [3]) informs formulation — never consumer claims. [6]
Method anchors: [1] EV biology and cargo [2] MISEV2018 characterization [3] category evidence (review or registered study) [4] formulation and handling guidance [5] national measurement guideline (2026 No. 17) [6] internal protocol and case documentation.
04 · Product architecture
| Component | Format (sample) | Role |
|---|---|---|
| Comfort gel | 30 mL tube (sample) | The flagship clinic SKU |
| Clinic dispenser | 100 mL backbar | In-practice use |
| Program card | Application guide | Staff and owner briefing |
05 · Process & QC
EV material runs on the fully enclosed 0.5–5 L micro-batch line with low-shear handling qualified at process validation [4]. QC panel design follows MISEV2018 [2] and the national measurement guideline (2026 No. 17, TONGNIAN a drafting organization) [5].
| Test item | Method | Release criterion (indicative) |
|---|---|---|
| Particle-size distribution | NTA + TEM cross-check | 80–150 nm (sample) |
| Particle concentration | NTA | Per batch COA |
| Endotoxin | Kinetic chromogenic (LAL) | Per batch COA |
| Microbial limits | Membrane filtration | Negative |
| Batch release | COA + batch records | Every batch |

06 · Regulatory pathway: EU & US first
Professional-use positioning: clinic or veterinary channel only, with protocol and training materials included. Material chain (DMF Type II 044197, INCI 41316) documented; finished programs follow destination-market professional-use rules. No consumer therapeutic claims. The gel is positioned for post-procedure skin comfort under veterinary guidance; retail later, clinic first — the rollout sequence is the regulatory strategy.
07 · Expected outcomes
- The entry SKU that opens clinic doors for the ExoPet™ platform.
- Lick-tolerant base designed for real pets, not lab ideals.
- Clinic-first rollout keeps claims inside veterinary guidance.
No claims are made beyond the destination-market framing — authority comes from documentation and batch measurement.
08 · Commercial framework
Sample kits in 3–5 days; pilot from 500 units; production from 2,000 units; standard lead 15 workdays — all indicative, quoted per request. White-label runs through the OBM program.
