An in-depth white paper on the chemistry, performance metrics, and supply chain of CAS 61789-32-0.
In the highly competitive daily chemical sector, consumer preference has definitively shifted away from harsh sulfates toward ultra-mild, bio-based alternatives. Among these, Sodium Cocoyl Isethionate (SCI), commonly referred to as "Baby Foam" due to its exceptional mildness, has established itself as the gold standard. SCI is an anionic surfactant derived from natural coconut oil fatty acids. It is characterized by high foaming capabilities, superior flash foam, and extreme mildness to skin and eyes.
For research and development directors at multinational personal care companies, purchasing high-quality SCI is not just a matter of sourcing a raw material; it is a critical step in ensuring formulation stability, skin barrier compatibility, and consumer trust. Unlike traditional surfactants like Sodium Lauryl Sulfate (SLS) or Sodium Laureth Sulfate (SLES), SCI maintains its performance in hard water and displays low skin-sensitization rates. This makes it the ideal core surfactant for solid cleansers (syndet bars), high-end liquid shampoos, and facial cleansers.
"The structural architecture of Sodium Cocoyl Isethionate provides a high hydrophobic chain length density coupled with a soft polar head. This unique molecular design prevents the surfactant monomer from penetrating the stratum corneum, effectively eliminating protein denaturation and subsequent skin irritation."
However, formulating with SCI presents unique chemical challenges. Because of its limited solubility in cold water, raw material quality (specifically particle size, free fatty acid content, and active matter purity) dictates the ease of dispersion. As a leading Sodium Cocoyl Isethionate factory and exporter, Suzhou Yuantairun Chemical Co., Ltd. resolves these issues by optimizing synthesis crystallization, providing global formulators with highly dispersible physical forms (granules, flakes, and fine powders) tailored to specific production parameters.
Quantifying our manufacturing capabilities and service scale to guarantee supply chain resilience.
Navigating the global shift toward solid formulations, clean-label compliance, and carbon footprint reduction.
The push for zero-waste packaging has triggered an exponential demand for syndet bars, solid conditioning bars, and powder facial washes. In these formats, SCI functions as the primary solid cleansing agent, providing structural integrity, stable foam under pressure, and rapid rinsing.
Global procurement teams prioritize vendors who offer integrated logistics, reliable container availability, and multi-tier quality control. A sudden change in purity can cause batch separation in industrial-scale runs. We mitigate this through automated process control and continuous GC analysis.
Leading cosmetic conglomerates audit factories based on carbon emissions, waste water treatment, and raw material sourcing. Our production plant is optimized for atom efficiency, utilizing direct condensation of coconut-derived fatty acids and sodium isethionate while recycling reaction water.
Our standard manufacturing specification limits for high-active Sodium Cocoyl Isethionate (85% and 95% grades).
| Test Parameter | YTR-SCI-85 Specification Limit | YTR-SCI-95 Specification Limit | Test Method |

| Free Fatty Acid (%) | 3.0% - 12.0% (Customizable) | ≤ 4.5% | Acid-Base Titration |
| pH Value (10% aq. solution) | 5.0 - 6.5 | 5.5 - 7.0 | pH Electrode Meter |
| Moisture Content (%) | ≤ 1.5% | ≤ 1.0% | Karl Fischer Titration |

| Heavy Metals (as Pb, ppm) | ≤ 10 ppm | ≤ 5 ppm | ICP-MS |
The free fatty acid content acts as a plasticizer in syndet bars. A level of 8-12% is often preferred for solid soap manufacturing, as it improves the extrusion flow and reduces cracking. Conversely, liquid formulations (such as sulfate-free baby shampoos and body washes) benefit from the YTR-SCI-95 grade, which has lower free fatty acids to prevent crystallization and cloudiness over time.
How our surfactants act as building blocks for modern skin, hair, and home care formulations.
Utilizing high-purity SCI in combination with Sodium Lauroyl Glutamate and Sodium Lauroyl Sarcosinate. This synergized system delivers high lather volumes while preserving the skin's natural lipid barrier.
Formulating with YTR-SCI-85 flakes, designed to withstand high industrial extrusion pressures. The high active content ensures long-lasting solid integrity and a smooth tactile feel.
Combining SCI with mild amphoteric co-surfactants like Cocamidopropyl Betaine. This combination suppresses the CMC (Critical Micelle Concentration) of standard surfactants, reducing potential eye sting.
Applying the high wetting capabilities of SCI to green home-care formulations. Highly active even in hard water, it cleans surfaces without leaving streaks or micro-abrasions.
Bridging pure organic synthesis with industrial eco-responsibility to protect global water ecosystems.
Modern consumers demand absolute raw material transparency. To support this, our production facility utilizes a highly refined, low-temperature direct esterification pathway. The raw materials used are derived from coconut trees that have not contributed to regional deforestation. Furthermore, the reaction parameters are monitored to control the synthesis of trace impurities such as free inorganic salts (primarily sodium isethionate residue), which can affect the hygroscopic nature and physical stability of the finished cosmetics.
Sodium Cocoyl Isethionate demonstrates rapid primary and ultimate biodegradability under both aerobic and anaerobic conditions, meeting the strict requirements of OECD 301. The breakdown products consist of simple fatty acids and sodium isethionate, both of which are readily utilized by wastewater treatment microorganisms. Unlike ethoxylated surfactants (which can release trace 1,4-Dioxane), SCI is inherently free from ethylene oxide adducts, ensuring safety for freshwater ecosystems.
