A hair conditioner base is a simple cream built from water, a cationic (positively charged) conditioning agent such as behentrimonium chloride, a fatty alcohol for body, and a preservative, adjusted to a slightly acidic pH of about 4 to 5. The positive charge is what makes it a conditioner rather than a lotion: it is attracted to the negatively charged hair surface, so it stays behind after rinsing and makes hair look smoother and comb more easily. Once the base works, you customize it with humectants, proteins and light oils for your hair type.
This guide gives you a complete rinse-off base formula in grams with the supplier use rates behind each ingredient, the method, and a customization chart. If you would rather start with a ready-made base you only need to adjust, my companion guide on creating your own hair conditioner base covers that route.
Why conditioners work: charge and pH
Hair has a low isoelectric point, which means its surface carries a negative charge in normal use. A review by Gavazzoni Dias and colleagues (2014, International Journal of Trichology) explains that this negative charge increases friction between fibers, which shows up as tangles and frizz. The same review tested the pH of 123 commercial shampoos and found most were above the pH of the hair fiber. A slightly acidic conditioner, around pH 4 to 5, helps offset that.
Cationic conditioning agents carry a positive charge. They are drawn to the negatively charged surface of the hair, form a thin, smooth film, and reduce static and drag during combing. That is the single most important part of the formula. Oils alone soften the feel, but they do not detangle the way a cationic agent does.
The building blocks, with supplier use rates
| Role | Ingredient (INCI) | Supplier use range | What it does |
|---|---|---|---|
| Main conditioning agent | Behentrimonium Chloride | 0.01 to 5% | Softer, smoother hair that is easier to detangle; antistatic |
| Alternative conditioning agent | Cetrimonium Chloride | 0.5 to 2.5% | Strong antistatic effect, better wet and dry combing |
| Natural-origin conditioning polymer | Guar Hydroxypropyltrimonium Chloride | 0.005 to 2% | Detangling and smoothing, derived from guar beans |
| Body and creaminess | Cetearyl Alcohol (fatty alcohol) | formulator's choice, usually 3 to 6% | Thickness and cushion; not drying |
| Conditioning additive | Panthenol (98%) | 0.5 to 5% | Humectant, conditioned feel |
| Protein | Hydrolyzed Rice Protein | 0.5 to 5% | Supplier lists it for an antistatic, cared-for feel |
| Humectant | Glycerin | 1 to 3% in conditioners | Softness and flexibility |
| Preservative | Leucidal SF Complete | 2 to 4% | Protects the water-based formula; works from pH 3 to 8 |
Use ranges for the conditioning agents, panthenol and rice protein are from the Spec-Chem Ingredients Catalogue (supplier data). The Leucidal range and pH window are from my Leucidal supplier notes.
The recipe: a 100 g rinse-off conditioner base
Each conditioning and care ingredient is at the top of its supplier range, per my house rule of using the manufacturer's highest recommended rate.
| Phase | Ingredient | % | Grams |
|---|---|---|---|
| A (water, heated) | Distilled water | 73% | 73.0 g |
| A (water, heated) | Glycerin | 2% | 2.0 g |
| A (water, heated) | Behentrimonium Chloride | 5% | 5.0 g |
| B (oil, heated) | Cetearyl alcohol | 5% | 5.0 g |
| B (oil, heated) | Jojoba seed oil | 1% | 1.0 g |
| C (cool-down) | Panthenol (98%) | 5% | 5.0 g |
| C (cool-down) | Hydrolyzed rice protein | 5% | 5.0 g |
| C (cool-down) | Leucidal SF Complete | 4% | 4.0 g |
| C (cool-down) | Citric acid solution (10%) | as needed to pH 4 to 5 | drops |
| Total | 100% | 100 g |
Method
- Sanitize beakers, a stick blender, a spatula and your bottle with 70% isopropyl alcohol.
- Heat phase A (water, glycerin, behentrimonium chloride) to 70 to 75°C (158 to 167°F).
- Heat phase B (cetearyl alcohol, jojoba) to the same temperature until fully melted. Hold both phases at temperature for about 10 minutes.
- Combine by pouring phase B into phase A and blending in short bursts for 1 to 2 minutes.
- Cool while stirring. The base thickens as it cools below about 50°C.
- Add phase C below 40°C (104°F): panthenol, rice protein and Leucidal SF Complete. Stir until smooth.
- Adjust pH to 4 to 5 with a few drops of 10% citric acid solution, checking with a strip or meter after each addition.
- Bottle and rest for 24 hours before judging the final thickness.
How to use it: after shampooing, squeeze out excess water, work a palmful through the lengths and ends, leave 2 to 3 minutes, then rinse well.
Customize the base for your hair
| Hair type or goal | Adjustment | What to avoid |
|---|---|---|
| Fine hair that goes limp | Drop jojoba to 0% and cetearyl alcohol to 4%, adding the difference as water | Butters and heavy oils |
| Coarse, dry or curly lengths | Raise jojoba to 3% and add 1% shea butter to phase B, lowering water by 3% | Very light, fast-rinsing bases that leave hair bare |
| Frizz on humid days | Keep pH at the low end (about 4) | High-pH additives |
| Thicker, richer cream | Raise cetearyl alcohol to 6% and lower water by 1% | Adding gums, which can turn the base stringy |
| Scented version | Up to 0.5% essential oil in phase C | Fragrance on a sensitive scalp |
The 10% rule for extras
Every liquid you add on top of the formula thins the base and dilutes the preservative. If you add more than about 10% of extra liquids such as aloe juice or hydrosols, reduce water by the same amount instead of stacking them on top, and keep the preservative at 4% of the total.
Leave-in conditioners are a different formula
Do not simply leave a rinse-off base in your hair. Leave-on products use lower levels of cationic conditioners because they stay on the scalp and skin all day, and some cationic ingredients have lower limits for leave-on use in certain markets. Build a leave-in as its own lighter formula, and keep it preserved: my Leucidal supplier notes specifically list leave-in conditioners as a product that needs a preservative, since they sit on hair and scalp for hours.
Preservation, storage and safety
- Always preserve. Conditioners are mostly water and are used in a warm, wet bathroom, which is ideal for microbial growth. Our Leucidal SF Complete at 4% is added in the cool-down phase.
- Use a pump or squeeze bottle, not an open jar, so wet fingers stay out.
- Shelf life: follow your preservative's guidance. Discard the batch if its smell, color or texture changes.
- Patch test on the inner arm for 24 hours if you have a sensitive scalp, and keep the conditioner out of your eyes.

Troubleshooting
| Problem | Likely cause | Fix |
|---|---|---|
| Hair still tangles | Too little cationic conditioner | Keep behentrimonium chloride at the top of its range |
| Hair feels coated or flat | Too much oil or fatty alcohol for your hair type | Use the fine-hair adjustment above |
| Base is thin or watery | Fatty alcohol not fully melted, or too many added liquids | Hold both phases at 70 to 75°C for 10 minutes and follow the 10% rule |
| Base separates | Phases at different temperatures when combined | Check both with a thermometer before mixing |

Frequently asked questions
What is the difference between a conditioner base and a lotion base?
The conditioning agent. A lotion uses a non-ionic emulsifier, while a conditioner uses a positively charged ingredient such as behentrimonium chloride that is attracted to the hair surface.
Is behentrimonium chloride natural?
It is usually made from plant-derived fatty acids, but it is processed, so most certifiers do not classify it as natural. Guar hydroxypropyltrimonium chloride is a natural-origin alternative, though it gives less slip on its own.
Can I use coconut oil as a conditioner instead?
Oil softens the feel of hair but does not provide the antistatic, detangling effect of a cationic conditioner, and it can be hard to rinse out.
Why is pH important in a conditioner?
A slightly acidic pH of about 4 to 5 helps hair feel smoother. It also keeps the formula inside the working range of preservatives such as Leucidal, which is pH 3 to 8.
Can I add peptides to my conditioner?
Water-soluble boosters can be added in the cool-down phase below 40°C. Keep the claims cosmetic: conditioners support the look of shinier, smoother, fuller-looking hair.
