At Croda we offer a range of surfactants, solvents, solubilisers and stability enhancers within our product portfolio to support your over the counter (OTC) formulations, such as soft gels, topical creams, suppositories, transdermal patches and syrups.
OTC medicines are non-prescription drugs that are safe, and effective for the use by the general public without the need to seek treatment by a health professional. The benefits of using OTC drugs include easy accessibility, lower costs, convenience, and consumer-empowering properties.

Rectal and vaginal
Rectal and vaginal administration routes are used for local as well as systemic drug delivery and can offer some unique advantages. The rectal and vaginal routes belong to the transmucosal routes of drug delivery and thus offer the advantage of bypassing first-pass metabolism. They both have a use in systemic drug delivery when the oral route is not available, or where the drug under consideration is not well suited for oral administration, however these are relatively less popular due to their anogenital nature and privacy aspects.
Our range of Super Refined™ excipients are manufactured using a proprietary process, in which impurities are removed, in order to maximise the drug product value. They have been specially designed to enhance the stability, solubility and delivery of APIs through the rectal and vaginal administration routes.
Our excipient portfolio includes:
- Stability enhancers
- Viscosity modifiers
- Suppository bases
SEDDS and SMEDDS
SEDDS and SMEDDS drug delivery systems are mixtures of oils, surfactants, solvents, and drug substance that rapidly and spontaneously form oil-in-water emulsions or microemulsions when introduced into aqueous phases under gentle agitation.Learn more
Achieving API solubility is one of the big challenges faced by formulators, with many APIs having low solubility. Our range of Super Refined pharmaceutical solvents can address this challenge, providing a range of polar and non-polar solvents that not only provide solubility, but also excellent stability for APIs.Learn more
