Sure - Schulke, (former Dow) Microbial Control, Lonza, Emerald Kamala.
To new classes - no. For perspective, a major effort was mounted a 4 or 5 years back organized by Green Chemical and Commerce Counsel (“3G”) and funded by the major companies - P&G, Unilever, etc. to find new preservatives. It was a complete bust - nothing identified worked. Here’s the very political report observing how well industry played together, completely ignoring the total failure of the effort.
I was contracted couple of years backas technical review by a major company for submissions responding to a similar search. Again nothing new of substance.
Development of novel solutions/chemicals clearly need critical financial and technical mass not found in academic and startup entities.
