Ingredient review
African Locust Bean Oil Complex
INCI: Pentaclethra Macroloba Seed Oil / Behenic Acid / Aminopropanediol Amides/Esters
A gentle conditioning ingredient that helps soften hair and skin without heavy greasiness.
In plain English
This ingredient is a lab-modified version of oil from the African locust bean (Pentaclethra macroloba). It is combined with behenic acid (a fatty acid from plants) and aminopropanediol (a small molecule) to create a compound that sticks to hair and skin, providing a smooth, soft feel without being overly oily. Think of it as a lightweight, modern conditioner that helps detangle hair and reduce frizz, while also making skin feel silky.

Quick decision guide
Useful, but context matters
African Locust Bean Oil Complex is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging African Locust Bean Oil Complex.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic conditioning agent created by reacting African locust bean seed oil with behenic acid and aminopropanediol. The result is a mixture of amides and esters that have both water-loving and oil-loving properties, allowing them to deposit on hair and skin surfaces.
How it works
The molecule has a fatty tail (from the oil and behenic acid) that adheres to the hair or skin surface, and a small polar head (from aminopropanediol) that helps it spread evenly. This coating reduces friction between strands, making hair easier to comb and less prone to breakage. On skin, it forms a thin, non-greasy film that locks in moisture and improves texture.
Pros
Gentle conditioning
Provides slip and softness to hair without the heavy, greasy feel of some oils, making it suitable for daily use.
Multi-surface benefit
Works on both hair and skin, improving texture and manageability in a single ingredient.
Cons and cautions
Potential buildup
On very fine or low-porosity hair, repeated use without clarifying shampoo may lead to product buildup over time.
Limited independent data
Most safety and efficacy data come from manufacturer studies rather than independent peer-reviewed research.
Best for
- People with dry or damaged hair seeking gentle conditioning
- Those who prefer plant-derived but effective conditioning agents
Use caution if
- Individuals with very fine or easily weighed-down hair who may experience buildup
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. Low irritation and comedogenic potential. No significant safety concerns reported in regulatory databases.
Research notes
Efficacy is supported by manufacturer data showing improved hair combability and softness. Independent peer-reviewed studies are limited, but the ingredient's components (behenic acid, aminopropanediol) are well-characterized and safe.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions known.
- Common uses
- Hair conditioners, Leave-in treatments, Skin creams, Lip balms
- Environmental note
- The African locust bean is a sustainable crop in West Africa, but the semi-synthetic processing may involve chemical reagents. Biodegradability data are not publicly available.
Good to know
- This ingredient is often used as a replacement for silicones in 'no silicone' hair products.
- Behenic acid is a natural fatty acid found in moringa and rapeseed oils.
