Our Position
Not a catalogue. A knowledge partner.
The best OEM relationships start with mutual understanding — of ingredients, regulations, and the science behind the claims.
Most factory websites show you MOQs and lead times. We show you the chemistry. MastraCare was built on a simple conviction: professional buyers — formulators, brand developers, procurement specialists — deserve access to the same depth of technical knowledge that lives inside our R&D team.
So we wrote it down, structured it, and published it. Every document in this knowledge base reflects real formulation decisions we make every day in our GMP-certified, ISO 22716 facility in Guangzhou.
Knowledge Architecture
Three dimensions of formulation expertise

How the knowledge base works for you
Research your ingredient or concern
Every topic page covers mechanism, formulation parameters, concentration ranges, stability considerations, and regulatory context — in one place, written by our R&D chemists.
Understand the regulatory landscape
Whether you’re targeting the EU, US, or Chinese market, our regulatory guides walk through NMPA, FDA MoCRA, and EU Annex requirements specific to cosmetic OEM brands.
Build your brief with confidence
Arrive at sourcing conversations with a clear formulation brief — the actives, the percentages, the format, and the claims you can substantiate.
Connect with our team
When you’re ready to develop, our GMP-certified facility and ISO 22716 processes are ready for your project — from MOQ planning through stability testing and export documentation.
Who We Serve
Built for professional beauty buyers
Independent & Indie Brands
Building your first or fifth product line? The knowledge base helps you speak the language of formulation before you walk into any factory conversation — protecting your IP and accelerating development.
Retail & Private Label
Evaluating OEM partners for a retail private label program? Our technical documentation gives you the specification depth to evaluate proposals with scientific rigour, not just samples.
In-House R&D Teams
Looking to outsource specific product categories or augment your internal pipeline? Our formulation technology guides align our capabilities with your existing technical standards.
Compliance & Market Access
Our regulatory market guides — covering NMPA, EU, and FDA — are written for professionals who need the technical substance behind compliance requirements, not marketing summaries.
Our Philosophy
Transparency is the new credential
The cosmetic manufacturing industry has a trust problem. Buyers can’t see inside factories. They can’t interrogate the science behind supplier claims. They can’t verify whether a formulation is truly built on clinical evidence or marketing language. So they rely on samples, audits, and reputation — all of which take time and money they often don’t have.
We decided to solve this differently. If we publish the science openly — the mechanisms, the concentrations, the stability challenges, the regulatory limits — then buyers can evaluate our competence before they ever send an enquiry. The knowledge base is our credential.
Somewhere between a scientific reference library and a formulator’s workbook, MastraCare’s knowledge hub exists to raise the standard of OEM sourcing conversations. We think the industry gets better when buyers know more — and when buyers know more, they find us.
