Production runs through a co-manufacturing system.
OKCLEAR is a people-and-pet health brand focused on cat allergen management. Founded by a team with a Zhejiang University pet-nutrition research background, it explores science-led solutions centered on specific IgY egg-yolk antibodies for allergens found in cat saliva, sebum and the coat environment.
Our starting point is simple: cat lovers should not have to choose between closeness and a comfortable home. Conventional approaches often separate diet, coat and environment into fragmented routines. OKCLEAR brings them together in one clear, lower-friction daily system.
To achieve this, we connect molecular-target research, IgY ingredient development, pet nutrition, formulation, grooming and real-home use. The result is more than a single SKU: it is a coordinated system across food, washing, wiping, spraying and litter care.
For China and global markets, OKCLEAR provides bilingual brand communication, product portfolios, technical dossiers and channel training, working long term with partners experienced in pet health, import registration and local education.
MANUFACTURING
Standardized production across seven pet-nutrition formats
Our manufacturing network develops and produces pet nutrition products across powders, tablets, pastes, drops, hard and soft capsules, and soft granules, supporting global brands with standardized R&D and manufacturing.
AUTOMATED LINE
Intelligent management from raw material to packing
Standardized clean workshops, automated production, low-temperature airflow micronization and microwave sterilization.
QUALITY CONTROL
62 testing indicators and HPLC capability
Testing spans composition, microorganisms and heavy metals, with batch-level raw-material and finished-product traceability.
R&D PLATFORM
Zhejiang University pet-nutrition research background
Research is advanced by a team with a Zhejiang University pet-nutrition research background, with Ragdoll cat observation facilities for in-vivo validation. The Fel d 1–8 patent strategy covers broad-spectrum IgY preparation, formulations and methods of use.

SCIENCE, EXPLAINED SIMPLY
How cat allergens move from coat to home
Cat hair is not the allergen itself. It is better understood as a vehicle. Following the mouth, coat and home explains why allergen management works best as a system.
Grooming: proteins reach the coat
During grooming, saliva-associated proteins can remain on the skin and coat.
Coat & dander: a transport route
Shed hair, dander and everyday contact can gradually move these fine particles beyond the cat.
Shared home: everyday accumulation
Sofas, bedding, clothing and indoor dust can become places where allergen particles settle.

Frequently asked questions
Can the AmiFree series treat my cat allergy?
No. The AmiFree series is designed for managing allergen load from cats and the home environment. It is not a medicine for human allergic disease and does not replace medical evaluation or treatment. Decisions about human symptoms, medication or living arrangements should be made with a qualified clinician.
Does it make my cat hypoallergenic or allergen-free?
No. Cats still produce allergens. The goal is to help reduce exposure, not to eliminate it entirely. No product can make a cat allergen-free.
What is Fel d 1 and why is it the core target?
Fel d 1 is a well-studied cat allergen protein found in saliva and skin secretions. Grooming moves it onto the coat, and dander and dust can carry it around the home. Fur itself is usually not the allergen. Fel d 1 has been associated with up to 96% of sensitization to cats in the literature and is the best-studied core component.
Reference: WHO/IUIS Allergen Nomenclature ↗Why egg-yolk IgY?
IgY is an egg-yolk antibody. Published laboratory studies show that anti-Fel d 1 IgY can bind the protein and reduce measured active Fel d 1. OKCLEAR uses this source-side approach; results from other tested products are not results for OKCLEAR.
Reference: Satyaraj et al., Journal of Immunology Research, 2021 ↗How do I use the Cat Allergen-Reducing Powder?
Mix the powder into the cat's regular dry or wet food, following the dose on the purchased product's label and the cat's weight. Directions can differ by SKU and cat weight; follow the label.
How long before I should evaluate results?
Follow the specific product directions and the measured endpoint. Published studies of a particular anti-Fel d 1 IgY cat diet observed changes in active Fel d 1 after about three weeks of continued feeding; that timeline is not an OKCLEAR powder result or promise. Dietary, grooming and home-care endpoints differ.
Reference: Satyaraj et al., Immunity, Inflammation and Disease, 2019 ↗Can it replace antihistamines or medical advice?
No. It is a pet- and home-side routine. Decisions about human symptoms, medication or living arrangements should be made with a qualified clinician. Seek urgent medical care for breathing difficulty, blue lips or face, severe wheezing, or rapidly worsening throat symptoms.
What does the "1 day" indicator mean?
Under defined product test conditions, target-allergen indicators changed in as little as one day. This is not a promise of human symptom relief in a day. The statement applies only to the powder + spray + shampoo combination test, not to individual products or human symptom improvement. Dietary, grooming and home-care endpoints differ.
- Separate measurable indicator change from household experience: the latter is also shaped by exposure load, individual sensitivity and the home.
- Published IgY-cat-food research observed significant active Fel d 1 reduction from week 3; it is a reference for sustained source management, not a universal timeline for every product.
Is it only Fel d 1, or Fel d 1–8?
Fel d 1 is one of the best-studied cat allergens and is associated mainly with saliva and sebaceous secretions. But cat allergy is not a one-component condition: Fel d 2, 4 and 7 can also contribute to different molecular sensitization profiles. OKCLEAR uses Fel d 1–8 as an R&D and testing framework so product design can consider multiple exposure pathways across the source, coat and home.
- A multi-target approach does not mean every home must address eight components at once; it means R&D should not reduce real exposure to one marker.
- For partners, it provides a more complete language for product development, testing and training.
Where does the research background come from?
The brand was started by a team with a Zhejiang University pet-nutrition research background. This statement describes the team research background; it does not mean OKCLEAR is an official Zhejiang University product, produced by Zhejiang University, or endorsed by Zhejiang University.
Which cats need a vet check before use?
Read the actual product label first. If your cat has special dietary requirements, a health condition or uses other supplements, consult a veterinarian. Directions can differ by SKU. Kittens, pregnant or nursing cats, and cats with chronic conditions should be evaluated by a vet before use.
Do you work with distributors and business partners?
Yes. OKCLEAR works with distributors, pet-health channels, specialty retail, e-commerce platforms, pet-food brands and research partners. We value partners who can review technical materials, communicate responsibly and support the channel over time.
- For a first discussion, share your company website, current channels, SKUs of interest, estimated initial volume and review questions.
- Partnership availability is assessed by product, project scope and applicable requirements.
