Bio Clean — Moisture-Lock Cleansing Oil

EVERY INGREDIENT, EXPLAINED

What's in the bottle

• MCT Oil (C8/C10)Base carrier oil

  INCI: Caprylic/Capric Triglyceride

  Fractionated medium-chain triglyceride — fast-absorbing, odourless, and exceptionally stable. Pulled from coconut, refined to isolate the C8 (caprylic) and C10 (capric) chains. Base oil of the formulation — its tactile smoothness and rapid absorption are why Bio Gold feels like a serum rather than an oil despite being entirely lipid-based.

  Sourcing: Coconut-derived.

• Polyglyceryl-4 OleateNatural-origin emulsifier

  INCI: Polyglyceryl-4 Oleate

  A plant-derived, natural-origin emulsifier. Its job inside Bio Clean is the trick that makes an oil cleanser rinsable: when you wet your hands during the second massage phase, Polyglyceryl-4 Oleate assembles the dissolved sebum, debris, and cleansing oils into a milky emulsion that lifts cleanly away with water. It is not a surfactant — it does not strip the skin's lipid barrier the way SLS, SLES, coco-betaine, and other foaming agents do. Structurally it is a tetra-glycerol backbone with a single oleic acid ester, which is what gives it a mild, skin-compatible HLB. The combination of solubilising power without stripping is why it sits at the heart of the Bio Clean system. It is also the reason we can formulate a cleanser with no preservatives, no synthetic surfactants, and no sulfates, and still deliver a thorough clean.

• Golden Jojoba Oil (virgin, deodorized)Sebum-mimetic carrier

  INCI: Simmondsia Chinensis Seed Oil

  Virgin-pressed and deodorized — it keeps the phytosterols and tocopherols, without the nutty smell of the raw oil. Wax-ester structure is a close match to human sebum — the skin recognises this as 'skin lipid' rather than occluding against it. Jojoba is technically a liquid wax, not an oil, and its ~98% long-chain wax ester structure gives it a stability and skin-recognition profile nothing else in the kingdom matches.

• Meadowfoam Seed Oil (refined)Stability anchor

  INCI: Limnanthes Alba Seed Oil

  The most oxidatively stable botanical oil routinely available. Approximately 95% of its fatty-acid profile is long-chain (C20 and above), with unsaturations at the ∆5 position rather than the more common ∆9 or ∆12. That geometric detail is why meadowfoam resists oxidation not only by its own chemistry but extends the stability of other oils it is blended with. The reason Bio Gold does not go rancid.

• Castor Oil (unrefined)Deep-pull cleansing and film-forming backbone

  INCI: Ricinus Communis Seed Oil

  The chemical reason castor oil is irreplaceable is ricinoleic acid — an unusual hydroxy fatty acid that comprises around 90% of castor triglycerides. Ricinoleic acid's hydroxyl group gives the oil a hydrophilic character unusual among vegetable oils, which is what lets it lift oxidised sebum and heavy debris from the pore without the stripping sensation of a surfactant. In Bio Clean it provides the 'pull' of the second massage phase. In Bio Glide it plays a different role — its high viscosity and mechanical film-forming ability create what we call the Castor-Grip: a thin, cohesive layer that the blade skates across rather than cuts through. This is the same mechanical principle at work in old-world barber preparations. We use the unrefined grade — the refined cosmetic version is more consistent in colour but loses the minor constituents that give the unrefined oil its tackier, more adhesive behaviour.

• d-alpha TocopherolAntioxidant (vitamin E)

  INCI: Tocopherol

  Natural vitamin E (d-alpha is the naturally occurring stereoisomer, as opposed to the synthetic dl-alpha). Protects the formula's oxidative stability in the bottle and contributes its own antioxidant behaviour on the skin. Works in combination with the tocopherol fraction of prickly pear to give Bio Gold a multi-pathway antioxidant profile without synthetic preservatives.

  Sourcing: Natural d-alpha, not synthetic dl-alpha.
