Private Label Castor Oil – OEM/ODM Manufacturer

Direct answer: GUOCUI produces this item to order as a single-ingredient castor carrier oil – a 10 mL / 0.33 fl oz amber glass bottle closed with a black screw cap and packed in a folding carton. The fill is pressed from Ricinus communis seed and is supplied either as a private-label retail unit or as a bulk ingredient for a buyer’s own formula. The brand block is blank on the reference pack; nothing is printed until the buyer approves artwork.

The featured image is a real photograph from the product archive: the amber bottle standing beside its carton on a plain white ground, with castor seed pods and mottled seeds arranged as botanical context. The reference artwork prints YOUR LOGO as a placeholder together with CASTOR OIL, CARRIER OIL, Cold-Pressed, Plant-Based and 0.33 fl. oz. (10 ml). The carton side panel carries INGREDIENT: 100% Pure Castor Oil, the feature list Cold-Pressed / Plant-Based / Hexane-Free, a suggested-use line covering hair, skin, nails and body care, and a caution block. The two process words – cold-pressed and hexane-free – are supplier pack copy. They are not the output of a test run by GUOCUI, and they are treated below as claims the buyer must have the material supplier substantiate for the destination market before they are printed on finished goods.

Product positioning

A carrier oil is bought as an ingredient rather than as a finished look, and that changes the whole brief. Nobody selects castor oil for its carton; they select it because a formulator needs a specific emollient behaviour, or because a single-ingredient oil is the most honest claim a young brand can print. The buyer is weighing cost per kilogram, a documentation set and a fill size – not a shade card.

That makes this pack an unusual object: a 10 mL retail unit is a marketing format built on top of a commodity. It suits a brand that wants one recognisable hero product to open a market, and it suits a buyer badly if the oil is going into a base of their own, because the glass, the cap and the carton add cost a drum never carries.

What a 10 mL amber bottle commits the buyer to

Ten millilitres is a trial, travel and discovery size. It is wide enough for a listing image, cheap enough to bundle, and small enough that a first run does not lock up much cash in oil. The trade-offs are concrete: cost per millilitre peaks at this fill, the carton panel is barely wide enough to hold an ingredient line, a feature list, a use direction and a legal block, and an amber body hides the fill, so the customer cannot judge colour or clarity. A buyer who needs any of those should be looking at 30 mL, 60 mL or 120 mL, or at a clear container – fill and pack changes are feasibility questions, not fixed limits.

Single ingredient versus blend

The pack in the reference artwork is unformulated on purpose: one oil, nothing added. A blend is a different commercial decision rather than a larger version of this one. Adding a lighter carrier softens the feel and changes how fast the oil disappears into the skin, but it also lengthens the ingredient list, may pull in an allergen review once fragrance is involved, and removes the one-ingredient story from the front of the pack. Both routes are open; the buyer should choose the one the brand can actually stand behind.

Suitable buyers

This format tends to land with five groups.

Single-ingredient beauty brands. Startups that build the entire proposition around one recognisable oil and sell on transparency rather than on a claim.

Hair and scalp care ranges. Castor oil is a long-standing carrier in scalp and edge-care lines, used neat or as the heavier half of a blend with a lighter oil.

Nail and hand care lines. Small fills suit cuticle and nail oils, where a brush or roller closure is usually part of the brief.

Formulators and independent makers. Soap, balm, lip and body producers who buy the oil as a raw material and mix it into their own base.

Gift, travel and discovery programmes. A small bottle with a printed carton is an easy component in a set or an amenity line.

Two caveats belong in the same breath. The first is regulatory: an oil presented purely as a cosmetic ingredient is handled as a cosmetic, but the moment a claim about thickening or growing hair or lashes appears, most markets stop treating it as a cosmetic and start asking for the evidence that category demands. The claim list should be settled before artwork, not after. The second is commercial: a buyer who needs bulk ingredient should be quoting on a drum or IBC basis instead of on this retail pack, because the pack economics work against them.

SEO and buyer keywords

The phrases below are the vocabulary purchase teams and marketplace search actually use in this category. They are listed so a listing or an RFQ can be aligned with it – not to be repeated on the page.

private label castor oil, castor oil OEM manufacturer, cold pressed castor oil supplier, hexane free castor oil wholesale, castor carrier oil 10 ml, bulk castor oil for cosmetics, ricinus communis seed oil supplier, castor oil private label hair care, castor oil for soap making bulk, custom label carrier oil China.

Two search patterns are worth separating, because they produce different quotations. A formulator hunting an ingredient needs a specification, a lot certificate and a packed weight. A brand hunting a finished unit needs a fill size, a label route and a carton. The same oil answers both enquiries, but the enquiry has to say which one it is.

Custom formula directions

On a single-ingredient oil, customisation is mostly about presentation and pack, though blends are available. What can move, and what cannot be stated here, is set out plainly.

What can be changed

Fill size and container: 10 mL as shown, or a larger fill in glass, PET or aluminium with a screw cap, dropper, pump or roller closure. Carton or no carton. Label route: a printed wrap label or direct decoration, in one language or several. Blend direction: castor oil paired with a lighter carrier or a botanical extract where a softer feel or a different product story is wanted. Fragrance, where the destination market’s allergen labelling is planned for from the beginning rather than retro-fitted.

What this page cannot answer

Concentration figures, lot composition, peroxide and acidity values, the origin of the seed and any process certification are all specific to a supplier and a lot. GUOCUI does not publish them here and does not invent them. They come from the documentation for the material actually offered, and the buyer should hold that documentation before a carton goes to print.

Packaging options

The unit in the photograph is a 10 mL amber glass bottle with a black screw cap inside a printed carton. Around it, the usual alternatives are a clear or frosted bottle where the fill needs to be visible, a dropper or roller closure for targeted use, a PET bottle where weight and breakage decide the choice, or a larger glass format for a professional or refill position.

Cartons are optional rather than automatic. Removing one lowers unit cost and shipping volume, but it also removes the surface that carries the ingredient line, the use direction and the caution text – and in most markets that text has to appear on the product or its immediate packaging. Panel space is the genuine constraint at 10 mL: brand block, product name, ingredient statement, fill statement and the legal block will fill it, so a second language has to be planned for rather than squeezed in at the end.

Sample and QC workflow

A carrier-oil project is short, and the order of the steps matters more than the speed of them.

1. Brief. Send the fill size, the pack direction, whether the oil is sold as-is or blended, the claim list you intend to use and the destination market.

2. Documentation review. The specification set for the offered material is reviewed with the buyer before anything is described as suitable – in particular any process claim such as cold-pressed or hexane-free, which has to be supported by whoever supplies that material.

3. Sample. A sample of the oil, and where a custom pack is involved a filled unit, is prepared for the buyer’s own evaluation and market testing.

4. Artwork. Label and carton files are approved, including the claim list settled earlier in the brief.

5. Bulk and inspection. Production is checked against the agreed specification, and the inspection scope – what is examined, on what basis, and by whom – is fixed in writing beforehand instead of assumed afterwards.

Where a destination market requires third-party testing, stability work or a safety assessment, that work is commissioned for that market and sits alongside routine production checks. GUOCUI does not present a supplier’s printed claim as a test result of its own.

MOQ and quotation

Minimum order quantity, unit price and lead time are quoted against the enquiry rather than published as standing figures, because all three move with the fill size, the pack, whether artwork is supplied or developed, and the order volume. Nothing on this page is a fixed price or a fixed MOQ.

For a usable quotation, include the destination market; the fill size and pack format; whether the oil is sold as-is or blended; whether artwork is supplied or needs developing; the claim list you intend to use; whether import or marketplace testing is required; and the expected volume, with a note if the first run is a market test.

Buyer FAQ

Is this oil cold-pressed and hexane-free?

Those words appear on the supplier’s reference artwork as pack copy. GUOCUI does not make the material and will not repeat a process claim it has not been given in writing. Before either word is printed on finished goods, ask for the specification or certificate that supports it from the party supplying the oil, and confirm it still applies to the lot being shipped.

What is the ricinoleic acid content?

Castor oil is characterised by a very high ricinoleic acid fraction, but the exact figure is lot-specific and is not published on this page. A number printed on a website is not evidence, and a buyer building a formulation or a label on a figure we invented would be badly served. Request the current specification for the material on offer.

Can the fill size be changed?

Yes. Ten millilitres is the size in the photograph and the one best suited to a trial or travel position. Larger fills, and a different container or closure, are a feasibility question to raise in the brief, since the closure, the panel space and the cost per unit all change with the fill.

Can the oil be blended or fragranced?

Blends and fragranced variants are possible, and they change the brief. A blend lengthens the ingredient list, and a fragrance brings an allergen declaration with it in most markets. If either is planned, say so before the artwork is drawn, because both affect what has to fit on a 10 mL panel.

Can I sell this as a hair growth or lash growth product?

That decision sits with the destination market, not with the pack. A claim that a product grows or thickens hair or lashes generally takes it out of the cosmetic category and into one that requires evidence a cosmetic file does not contain. The safe route is to keep the presentation to what the oil is and how it is used, and to have any growth-type claim assessed for the market it will be sold in.

What should a buyer send to start?

The destination market, the fill size and pack direction, whether the oil is sold as-is or blended, the claim list, whether artwork exists, whether testing is required, and the expected volume. With those, feasibility, a sample and a quotation can be scoped.
