Coleus amboinicus Essential Oil, 500 ml

Coleus amboinicus oil, 500 ml for repeat manufacturing

Once a product built around Coleus amboinicus is on the market, the job shifts from discovery to consistency. This half-litre container serves that stage. The oil is distilled from the leaves of the herb also known as Plectranthus amboinicus or Cuban oregano. Its card states the INCI name Coleus Amboinicus Leaf Essential Oil and India as the country of production.

How far 500 ml goes

At 0.5 % in leave-on products, 500 ml of oil covers roughly 100 kg of finished goods. In rinse-off products dosed at 1 %, it covers about 50 kg. These figures make planning straightforward. You can estimate how many production cycles one lot will cover and schedule purchasing around your busy season instead of reordering in a hurry.

Good practice with a production lot

On opening a new container, draw a retention sample into a small labelled bottle and keep it for the shelf life of the products it goes into. If a customer ever queries the scent, you can compare against that reference straight away. Record the lot number on every batch sheet.

Typical production uses

Shower gels and shampoos

Premix the oil with a solubiliser in a side vessel and add it near the end of the process. Surfactant bases are available under wholesale surfactants.

Balms and body oils

Add the oil once the mass has cooled to 40 °C.

Home fragrance

In diffuser bases, dilute Coleus in a suitable solvent and confirm the ratio on a pilot run.

Scaling up without surprises

Large volumes heat and cool more slowly than lab beakers, so tie the point of addition to the batch temperature, not to the clock. Keep the familiar guideline of 0.2 to 0.5 % for leave-on and up to 1 % for rinse-off products, and let the safety assessment confirm final levels.

Documentation for the batch file

Gathering these papers when the container arrives is far easier than reconstructing them later.

Range partners

In production lines Coleus most often sits with rosemary, lemongrass, cedarwood and grapefruit. Floral partners are used sparingly. A common production pairing is Coleus with lemongrass in a fresh men's shower gel, or with cedarwood in a solid body balm, where the woody base rounds off the sharp herbal top.

Country of production India, INCI Coleus Amboinicus Leaf Essential Oil, pale yellow to greenish yellow, clear and of medium fluidity, pack size 500 ml.

Production example: shower gel, 10 kg

To 8.5 kg of shower gel base add 1.2 kg of water and 150 g of glycerin. In a side vessel mix 60 g of polysorbate 20 with 50 ml of Coleus oil and 30 ml of grapefruit oil, add this to the base, stir at low speed and adjust viscosity with salt. To trial a variation before a run like this, use the 50 ml bottle. The wider range is in wholesale essential oils, and emulsified products will need wholesale emulsifiers.

Storage

Store the container tightly closed in a cool, dark stockroom, and decant working quantities into a smaller glass bottle.

Planning a refill cycle

With 500 ml on the shelf, record the date the container was opened and the batches made from it. Comparing the scent of the third batch with the first shows whether the herbal top note is holding up. If it starts to flatten, decant the remainder into smaller amber bottles filled to the neck so that less air sits above the oil.

FAQ

How much product does 500 ml cover?

About 100 kg of leave-on products at 0.5 %, or 50 kg of rinse-off products at 1 %.

Why keep a retention sample?

It gives you a reference for the lot's scent if questions come up later.

Does the process change in large batches?

Yes. Add the oil based on the batch temperature rather than elapsed time.
