Conditioning Value Calculator — Blend Conditioning Index

A conditioning value calculator here means: assign each oil a relative conditioning score, then compute Σ(weight × score) ÷ Σ(weight). The scores are not universal constants—they are compact teaching anchors so you can rank blends consistently inside SoapLab. Always pair with the soap calculator for alkali.

Customers ask for “mild” or “moisturizing” bars—words that depend on fatty acids, superfat, and process. A higher modeled conditioning index often correlates with softer-profile oils, but cleansing oils can still dominate feel if percentages are high. Use the index to steer experiments, not to make medical claims.

Subscription box makers use indices internally to keep seasonal releases “on brand” while swapping what is affordable each quarter—document the oil story when price forces a substitution.

Shea and castor heavy: Index rises—watch softness vs hardness on the hardness calculator. Coconut heavy: Index may fall—pair with superfat tests via the superfat calculator.

• Optimizing index only and ignoring longevity.
• Confusing modeled conditioning with clinical moisturization.
• Skipping cure comparisons.
• Raising soft oils without checking hardness — bars can mush.
• Marketing “ultra mild” from an index alone — keep claims lawful.

Mildness talk on labels must stay cosmetic and truthful. Lye safety and GMP remain non-negotiable regardless of index.

If you compare your bar to syndets or detergents in marketing, keep comparisons factual and region-appropriate—this calculator does not measure synthetic surfactant performance.

When your conditioning story depends on a specific oil lot, log iodine and fatty acid specs from the COA alongside this index for audits.

Blend (940 g oils): sunflower 40% (376 g), avocado 30% (282 g), cocoa butter 15% (141 g), coconut 10% (94 g), castor 5% (47 g).

Reading: The conditioning index should lean softer than a coconut-heavy laundry bar—compare numerically to your previous SKU before you commit to a 20 kg order.

Next checks: Run cleansing value on the same grams, then set superfat in the superfat calculator after you like the tradeoff story.

Instead of quoting “index 62,” describe outcomes: rinses clean, leaves light skin feel, pairs with winter dryness marketing—always aligned with real tests. Keep a one-page chart that maps index ranges to your internal SKU tiers so new hires do not reinvent adjectives every season.
