MARU ingredientEvergreen tree

Macadamia

Macadamia integrifolia

An Australian rainforest tree that became one of southern Africa's great orchard crops, and the light, palmitoleic-rich base oil of both MARU body oils.

Macadamia nuts beside pale macadamia seed oil

Native to Australia, not to Africa. Included because MARU uses South African macadamia oil; the map shows orchard country, not a native range.

Distribution

Where it grows.

Macadamia integrifolia is native to south-east Queensland and north-east New South Wales. In southern Africa it exists as an orchard crop, led by South Africa's Mpumalanga, KwaZulu-Natal and Limpopo provinces, with commercial plantings in Malawi, Mozambique and Zimbabwe. The highlighted countries are growing countries, not a native range.^[1][2][3]

Climate

The environmental envelope.

Rainfall

Managed orchards

A farmed crop; a wild rainfall envelope does not apply

Temperature

Hot subtropical

Described as ideal for production; cold snaps and late rains cut the 2025 crop

Altitude

Lowveld to coast

Mpumalanga Lowveld, the KwaZulu-Natal coast and midlands, Limpopo

These describe South African orchard conditions from an industry report, not the species' native rainforest envelope in Australia.^[2]

Harvest season

A March to July harvest

In South Africa flowering begins in July, nuts set by spring, oil accumulates through summer and harvest runs from March into June or July. Nuts are collected from the ground by hand or with sweepers, then de-husked and cured before processing.^[2]

Sustainability

A farmed oil with farmed questions

A plantation crop raises different questions from a wild harvest: land converted from other crops, input costs, and prices that fell by nearly half in 2023 before recovering. MARU's macadamia oil is South African; the ingredient guide covers sourcing, and this Atlas maps the crop, not the supplier.^[2]

Chemical composition

Kernel-oil fatty acids.

Ranges across 15 cultivars grown in China in one study. South African orchard oil will differ in detail, and the bars mark the middle of each range.^[4]

Oleic61.7–66.5%

Palmitoleic13.2–17.6%

Palmitic6.8–8.3%

Stearic2.5–4.1%

Eicosenoic2.2–3.2%

Linoleic1.2–2.5%

Wildlife interactions

Part of a living system.

An orchard, not a woodland

Orchards are managed systems. The report names the stink bug and the macadamia nut borer as key pests, and cold, heat and hail as the weather risks that shaped the 2025 crop. That is the ecology of a farmed tree.^[2]

Replacing other crops

Macadamias are increasingly replacing sugarcane and citrus on South African farms, with KwaZulu-Natal showing the fastest growth and many orchards younger than ten years.^[2]

Traditional relationships

Knowledge has context.

A short history on this continent

There is no long African tradition to record. Macadamia reached southern Africa as a plantation crop within living memory; the industry's own growth curve, from about 6,750 hectares in 2001 to over 81,000 in 2024, is the story here.^[2]

Food plant of eastern Australia

Kew records the species as a food and medicinal plant. Its deep human history belongs to the rainforests of eastern Australia, not to this region, and the Atlas does not borrow it.^[1]

Light, monounsaturated, low in linoleic

Very high oleic and palmitoleic content with little linoleic acid explains why macadamia oil feels light and absorbs quickly, and why formulators use it as a base that carries richer oils. It is a fatty-acid explanation, not a clinical claim.^[4]

Compositional evidence only

The Atlas found solid compositional chemistry for macadamia oil but cites no human topical study of the oil on skin. Claims that its omega-7 content makes it 'skin-identical' should be read as a chemical resemblance, not a demonstrated outcome.^[4]
