Processing Methods & Reference Formulations
A. Shampoo
Optimize SLES concentration for effective cleansing while minimizing irritation, and to include moisturizing agents to offset potential dryness and enhance scalp comfort. Add it slowly under gentle stirring to minimize foam generation. Maintain formulation pH between 5.5–6.5 for scalp compatibility and stability.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Sodium Lauryl Ether Sulfate (SLES, 70%) | 8.00% |
| Cocamidopropyl Betaine | 5.00% |
| Glycerin | 3.00% |
| Citric Acid (Anhydrous) | 0.50% |
| Phenoxyethanol (Preservative) | 0.50% |
| Fragrance | 0.50% |
| Demineralized Water | 82.50% |
B. Body Wash
Always combine SLES with a milder co-surfactant like Cocamidopropyl Betaine (CAPB) to reduce skin irritation and boost foam quality. Add slowly under gentle stirring to avoid excessive foaming. Adjust pH to 5.0–5.5 for skin compatibility and optimal product performance.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Sodium Lauryl Ether Sulfate (SLES, 70%) | 10.00% |
| Cocamidopropyl Betaine | 5.00% |
| Glycerin | 3.00% |
| Sodium Chloride | 1.00% |
| Preservative (e.g., Phenoxyethanol) | 0.50% |
| Fragrance | 0.50% |
| Citric Acid (to adjust pH) | 0.50% |
| Demineralized Water | 79.50% |
C. Laundry Detergent Liquid
In detergent production, pre-dilute Sodium Lauryl Ether Sulfate (SLES) with deionized water before adding to the batch to prevent gel formation. Add it slowly under gentle stirring to maintain smooth consistency and avoid air entrapment.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Sodium Lauryl Ether Sulfate (SLES) | 9-10% |
| LABSA (96%) | 3-6.2% |
| Caustic soda | 0.2-0.83% |
| CDEA (70%) | 1-2% |
| AEO-9 | 1-4% |
| EDTA-2Na | 0.2-0.5% |
| Deionized water, | 50-60% |
| Fragrance, Dye, Preservatives, Salt (NaCl) |
D. Liquid Soap
Pre-dilute SLES (70%) with deionized water to ease incorporation and reduce foaming during mixing. In liquid soap production, add Sodium Lauryl Ether Sulfate (SLES) slowly to the water phase under gentle stirring to avoid excessive foaming. Combine with mild co-surfactants (e.g., CAPB) to enhance foam and skin feel.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Sodium Laureth Sulfate (SLES 70%) | 5% |
| Sodium Lauryl Sulfate (SLS 92%) | 1.5% |
| Cocamidopropyl Betaine | 5% |
| Cocamide DEA (CDEA) | 1% |
| Glycerin | 1% |
| EDTA-2Na | 0.1% |
| Salt | 2% |
| Deionized Water | 70-80% |
| Pigment |
