Sandalwood Shampoo Formulation - Sulfate free shampoo
Introduction: Why Choose Sulfate-Free Shampoos?
Sulfate-free shampoos are gentle on hair and scalp, making them ideal for all hair types, especially color-treated or sensitive hair. They use mild surfactants that cleanse without stripping natural oils, while conditioning agents and hydrolyzed proteins nourish and repair hair.
This guide explains how to create a clear, sulfate-free sandalwood shampoo using natural surfactants, conditioning ingredients, and carefully balanced additives for a mild, effective hair care solution.
Key Ingredients and Their Functions
1. Mild Surfactants (Phase A)
| Ingredient | Type | Function |
| Sodium Lauroyl Sarcosinate | Anionic surfactant | Mild cleanser with good foaming properties |
| Coco Betaine | Amphoteric surfactant | Boosts foam, increases viscosity |
| Coco Glucoside | Non-ionic surfactant | Enhances mildness; alternative: Decyl glucoside |
2. Conditioning Agents (Phase B & D)
| Ingredient | Type | Function |
| Glycine | Amino acid | Moisturizes, conditions, makes hair look healthy |
| Glycerin (optional) | Humectant | Adds moisture to hair |
| Polyquat 7 | Cationic polymer | Reduces frizz, increases shine |
| Hydrolyzed Proteins (Rice, Wheat) | Protein | Repairs damaged hair; alternatives: oat protein, milk protein |
| Olivem 300 | Emollient & foam enhancer | Adds mild conditioning and foam stability |
3. Fragrance, pH Adjusters & Preservatives (Phase C & D)
| Ingredient | Function |
| Sandalwood Fragrance Oil | Provides pleasant scent; ratio with Polysorbate 80 must be tested to avoid cloudiness |
| Polysorbate 80 | Solubilizer |
| Sodium Gluconate | Chelating agent |
| Lactic Acid | pH adjuster |
| Geogard ECT | Preservative |
| Salt | Thickener |

Equipment required:
- 100ml glass beakers
- Stirring rods and spatulas
- Heating mantle or double boiler
- Glass bottle or serum container
- Precision weighing scale (0.01g)
- Measuring cups
- Gloves
Step-by-Step Procedure
1. Measure and prepare phases:
- Phase A (surfactants + water)
- Phase B (glycerin, glycine, sodium gluconate, salt)
- Phase C (Polysorbate 80 + fragrance oil)
- Phase D (Olivem 300, Polyquat 7, Hydrolyzed proteins, preservative, lactic acid)
2. Mix Phases B & C: Stir well to ensure complete dissolution.
3. Combine phases: Slowly add Phases B, C, and D into Phase A while stirring gently.
4. Adjust pH: Use lactic or citric acid to reach pH ~5.5. Adjust thickness by adding up to 0.5% more salt if needed.
5. Final packaging: Pour the shampoo into a clean bottle.
Tips for Best Results
- Use transparent fragrance oils to maintain clarity.
- Avoid over-heating surfactants; it may reduce foam.
- Test any substitution of proteins or surfactants for compatibility.
- Store shampoo in a cool, dry place.
Common Substitutions & Variations
| Ingredient | Alternative | Notes |
| Coco Glucoside | Decyl Glucoside | Foam may differ |
| Hydrolyzed Proteins | Oat, Milk Protein | Adjust % based on protein type |
| Lactic Acid | Citric Acid | Adjust carefully to pH 5.5 |
| Salt | Xanthan Gum / Carbomer | For natural thickening |
FAQs
Q1: What makes this shampoo sulfate-free?
A1: It uses mild surfactants like Sodium Lauroyl Sarcosinate and Coco Glucoside instead of harsh sulfates, making it gentle on hair and scalp.
Q2: Can I replace wheat and rice proteins with other proteins?
A2: Yes, proteins like oat or milk protein can be used. Foam and texture may vary slightly.
Q3: How can I make a clear shampoo without cloudiness?
A3: Ensure the fragrance oil is properly solubilized with Polysorbate 80. Test ratios before mixing into the shampoo.
Q4: How do I adjust shampoo thickness?
A4: Salt can be increased slightly (up to 0.5%) or natural gums like xanthan gum can be used.
