I'll repost an answer
to the same question that I just posted on Quora. I also have a couple of contacts who make feminine hygiene products if you'd like to reach out to me directly.
Finding the right contract manufacturer for skincare, beauty [and femininehygiene] products is a challenge. Your best bet: networking with people in the industry.
There are thousands of contract manufacturers and most have things that they specialize in (natural, OTC, skincare, color, etc.).
publishes a directory once a year. (I think it's available via their clunky website, too).ThomasNet
is also worth a search.
Directories are good for finding companies you probably haven't heard of, especially if you're looking for someone near you. But it's hard to get a good sense of what these manufacturers are good at.
Trade shows are also an option.Cosmoprof North America
andHBA New York
are two I've checked out and there are many more. (Trade show websites show lists of past and future exhibitors and speakers that are worth checking out, too).
As I said above, your best bet may be networking. But the beauty industry is definitely not as open as tech.
If you meet owners of beauty brands they'll often be reluctant to share with you who does their manufacturing. But if they won't share the name of their manufacturer, they often have a good Rolodex and may be willing to point you to others.
