Choosing Your First Soap Oils: A Canadian Maker's Guide

The most common question in beginner soap groups: "What oils should I start with?"

The honest answer: four oils is plenty for your first six months. Most experienced makers still rotate through a core six. Here's what each major soap oil actually does, and how to combine them into something balanced.

How soap oils contribute

Every oil brings a fatty acid profile that produces a different soap behaviour. Saturated fats (lauric, myristic, palmitic, stearic) make hard, cleansing, bubbly bars. Unsaturated fats (oleic, linoleic, ricinoleic) make softer, conditioning, creamy bars. Real soap is a balance of both.

Use the soap calculator's quality scores to see this live — Hardness/Cleansing/Bubbly come from saturated fats; Conditioning/Creamy come from unsaturated.

The core four oils

1. Olive oil — the workhorse conditioning oil

Olive oil is the foundation of most beginner bars. High in oleic acid (~70%), it produces a mild, creamy, slow-tracing soap that's gentle on skin.

• Quality contributions: Hardness 17, Cleansing 0, Conditioning 82, Bubbly 0, Creamy 17
• Typical use: 30–80% of your oil weight
• Notes: Pomace grade is fine for soap — you don't need extra-virgin. Cures slowly, gets better with time.
• Where to buy: Costco, any grocery store, or Canadian soap suppliers in 4 L tins.

2. Coconut oil 76° — the cleanser and bubbler

Coconut oil is the cleanser. High in lauric and myristic acids, it produces big bubbles, hardness, and oil-cutting power. Too much and it's drying.

• Quality contributions: Hardness 79, Cleansing 67, Conditioning 10, Bubbly 67, Creamy 12
• Typical use: 15–30% in regular bars. 60–80% in salt bars (with high superfat).
• Notes: "76°" refers to the melt point in °F. The default kind. Refined is unscented; unrefined smells like coconut.
• Where to buy: Costco bulk tubs, Canadian Tire, or soap suppliers.

3. Palm oil — the hardener and stable bar builder

Palm oil splits the difference between coconut's hardness and olive's conditioning. It's why so many recipes use it. Sustainability concerns are real — look for RSPO-certified sourcing.

• Quality contributions: Hardness 50, Cleansing 1, Conditioning 49, Bubbly 1, Creamy 49
• Typical use: 15–30% if using it
• Palm-free alternatives: Shea butter (45 hardness, 53 conditioning) or cocoa butter (61 hardness) substitute well at similar percentages

4. Castor oil — the lather booster

Castor oil is mostly ricinoleic acid (~90%) — unique among soap oils. It dramatically boosts lather and adds a creamy stability to bubbles. Use sparingly.

• Quality contributions: Hardness 16, Cleansing 0, Conditioning 85, Bubbly 95, Creamy 1
• Typical use: 3–8% — over 10% makes the bar soft and slow to trace
• Notes: Drugstore castor oil is fine for soap. Don't pay artisan-supplier prices for it.

Suggested first-batch ratio

The Balanced Beginner Bar:

• 50% Olive oil
• 25% Coconut oil 76°
• 20% Palm oil (or 20% shea butter for palm-free)
• 5% Castor oil

This lands every quality score in the recommended range, traces at a comfortable speed, and yields a bar that's mild, lathery, and beginner-forgiving. Open it in the calculator to play with the numbers.

When to add a fifth oil

After three or four batches with the core four, you're ready to add character oils. Best beginner-friendly additions:

Shea butter (palm replacement / luxury feel)

• Quality: Hardness 45, Conditioning 53, Creamy 45
• Use: 10–20% — replaces palm or adds creamy luxury
• Notes: Refined is unscented; raw has a smoky-nutty smell

Sweet almond oil (light luxury)

• Quality: Hardness 9, Conditioning 90, Creamy 9
• Use: 5–15% — adds a silky after-feel
• Notes: Pricier than olive but a small percent goes a long way

Avocado oil (rich, vitamin-A bonus)

• Quality: Hardness 20, Conditioning 79, Creamy 20
• Use: 5–15%
• Notes: Refined avocado is yellow-pale; unrefined is dark green and adds colour to the bar

Cocoa butter (hardness + faint chocolate scent)

• Quality: Hardness 61, Conditioning 38, Creamy 38
• Use: 5–15% — partial palm substitute
• Notes: Deodorised cocoa butter avoids the chocolate smell when you don't want it

Oils to avoid until you're more experienced

• Stearic acid at over 5% — accelerates trace dramatically and can seize a batch in seconds
• Beeswax — extremely slow trace, finicky temperatures
• Hemp seed and flaxseed oil at over 10% — high linolenic acid causes rapid rancidity (DOS) without ROE
• Pomegranate, raspberry seed, blackcurrant — all fine in tiny amounts (1–3%) but expensive and not where beginners should spend money

Reading the calculator's quality scores

Open any recipe in the calculator and you'll see eight quality scores:

• Hardness (29–54 range): how firm the bar feels and how long it lasts in the shower
• Cleansing (12–22): how much oil/grease the bar strips. Higher = drier skin.
• Conditioning (44–69): moisturising feel from unsaponified oils
• Bubbly (14–46): big, frothy bubbles
• Creamy (16–48): dense, lotion-like lather
• Longevity (54+): how long the bar lasts in normal shower use
• Iodine (41–70): stability — lower is more shelf-stable, higher fights DOS
• INS (136–165): combined index of overall bar quality

If a score lands outside the recommended range it's not always a problem — high-coconut salt bars are intentionally over-cleansing, Castile is intentionally low-bubbly. But the ranges tell you where the trade-offs are.

Buying oils in Canada

A few suppliers Canadian indie makers regularly mention (we maintain a grouped-by-province directory):

• New Directions Aromatics (Mississauga, ON) — broadest range
• Voyageur Soap & Candle (Surrey, BC) — west coast
• Saffire Blue (Woodstock, ON) — supplier-friendly minimums
• Coop Coco (Montreal, QC) — Quebec
• Windy Point Soap Making Supplies (Calgary, AB) — prairies

For everyday oils (olive, coconut, palm) Costco bulk pricing usually beats specialty supplier pricing. For specialty oils, suppliers are unbeatable.

Cross-reference SAP values with your supplier's spec sheet. A 1% lye error is the difference between a great bar and a lye-heavy harsh one. Always run new oils through the calculator before committing to a full batch.
