Terms
Last updated 14 November 2026
The short version: this site is here to help you learn about my work and pick up some science along the way. Here's what that means in practice.
Using this site
Circular Scientist is run by Radha K, a cosmetic scientist based in Singapore. By using this site, joining a session or signing up to the newsletter, you agree to these terms. Use the site to learn about my services and free resources. Please don't copy it, scrape it or try to break it.
My content
Everything here, plus my Instagram posts, workshop slides and articles, is my work. You're welcome to share links and talk about it. You can't republish it, sell it, or present it as your own without my written permission.
Education, not formulation advice
My free content is general education. It isn't advice for your specific product, and it doesn't replace a safety assessment, stability testing or regulatory review. Before you launch anything, get it properly assessed. If you want advice for your product, that's what a discovery call is for.
Working together
Paid consulting is covered by a written proposal that we both agree before any work starts. That proposal sets out the scope, fees and who owns what. If it ever conflicts with this page, the proposal wins.
Talks, workshops and the newsletter
Sessions may move or be cancelled. If that happens, I'll let you know. The newsletter is for people who sign up, and you can unsubscribe any time from the link in every email.
Links to other sites
I link to places like Instagram, LinkedIn and booking tools. I'm not responsible for how those sites work or what they do with your data.
The legal bits
These terms are governed by the laws of Singapore. I may update them from time to time. The date at the top shows the latest version, and using the site after an update means you accept the changes.
