      The Premier Supplier
      Augustus Oils Ltd, in harmony with nature - to present it at its best...
      A wealth of experience, expertise and knowledge has allowed Augustus to bridge the gulf in expectation and trust between growers and users of natural ingredients. The Company works in partnership with customers on the one hand, and growers, farmers and distillers on the other. Both users and producers can then focus on exactly what they do best, while skilled Augustus technicians closely monitor and control the delivered product. This ensures users can have the confidence that they will receive the best raw materials suited to their requirements. Augustus has invested in modern, well equipped laboratories to provide unparalleled control of quality, and a development environment that continues to produce innovative ranges of natural ingredients. The strength of the company is built on both its comprehensive knowledge base, and extensive stocks of raw materials for both fragrance and flavour use. To complement its range of conventional and Organic Essential Oils and Aroma Chemicals, Augustus also offers a steadily increasing range of its own, UK manufactured Natural Extracts, Absolutes, Resinoids and Natural Chemicals. These again are fully tested and certificated, and very tightly quality controlled. Augustus is committed to promoting the use of natural ingredients, wherever the potential lies and to provide an environment of support and trust to both our customers and suppliers.
