Sodium Cocoyl Isethionate (SCI) for Mild Cleansing & Shampoo Bars

Bulk Sodium Cocoyl Isethionate for shampoo bars, syndet bars, facial cleansers and sulfate-free personal care formulations.

Sodium Cocoyl Isethionate, commonly known as SCI, is a mild anionic surfactant valued for its dense, creamy foam and comfortable skin feel.

It is especially popular in solid shampoo bars and syndet cleansing bars, but it can also be used in facial cleansers, body wash, baby care and other mild cleansing systems.

Tanmu Biotech supplies Sodium Cocoyl Isethionate for commercial production, with technical documentation, samples and international shipment support available for professional buyers.

Sodium Cocoyl Isethionate Specifications

Please refer to the latest COA and TDS for the current batch specification.

What Is Sodium Cocoyl Isethionate?

Sodium Cocoyl Isethionate (SCI) is a mild anionic surfactant derived from fatty acids and isethionate chemistry.

In personal care formulations, SCI is used to provide cleansing and rich foam while helping formulators create milder cleansing systems than those based entirely on traditional high-detergency surfactants.

Because of its characteristic dense and creamy lather, SCI has become particularly well established in:

• solid shampoo bars
• syndet cleansing bars
• facial cleansers
• body cleansers
• sulfate-free cleansing formulations

It is sometimes referred to in the industry as “Baby Foam”, reflecting its long-standing use in mild cleansing applications.

Why Is SCI Popular in Shampoo Bars?

SCI has become one of the most widely used surfactants in modern solid shampoo bars.

The reason is not simply foam.

A well-formulated shampoo bar needs to balance cleansing performance, foam density, bar structure, processing characteristics and after-feel.

SCI can contribute:

• rich and creamy lather
• mild cleansing
• a dense bar structure
• good sensory properties
• compatibility with other mild surfactants
• flexibility in sulfate-free formulations

For formulators developing premium shampoo bars, SCI is often used as a primary surfactant or as part of a blended surfactant system.

Main Applications of Sodium Cocoyl Isethionate

Shampoo Bars

SCI is especially well known as a surfactant for shampoo bars.

It creates dense foam and works well in solid cleansing systems when combined with suitable co-surfactants, conditioning ingredients, oils and structuring agents.

Syndet Bars

SCI is widely used in synthetic detergent bars where formulators want a milder alternative to conventional soap-based cleansing systems.

Facial Cleansers

Its mild cleansing profile makes SCI suitable for powder cleansers, solid facial cleansers and selected cream or paste cleansing systems.

Shampoo

SCI can be incorporated into mild shampoo systems, although processing requirements depend on the product format and total surfactant blend.

Body Wash and Body Cleansers

SCI can be used together with other surfactants to create creamy foam and a softer cleansing profile.

Baby and Sensitive-Skin Cleansing Products

SCI is widely associated with mild personal care formulations. The suitability of any finished product for babies or sensitive skin should always be confirmed through appropriate formulation and safety evaluation.

SCI Granules vs SCI Powder

One of the most common questions from commercial buyers is whether to choose SCI granules or SCI powder.

Neither form is automatically “better.”

The most suitable choice depends on your equipment, formulation and manufacturing process.

If you are unsure which SCI form is suitable for your production line, send us your application and required quantity when requesting a quotation.

SCI vs SLSA

Both Sodium Cocoyl Isethionate (SCI) and Sodium Lauryl Sulfoacetate (SLSA) are used in mild cleansing formulations, but they are not interchangeable in every application.

For shampoo bars and syndet cleansing bars, SCI is one of the most established choices.

For bath bombs and products where high foam volume is important, SLSA is often preferred.

Some formulators use both surfactants in different products within the same personal care range.

SCI vs SLMI

SCI and Sodium Lauroyl Methyl Isethionate (SLMI) belong to the broader family of mild isethionate surfactants, but their formulation behavior differs.

SCI is particularly well established in solid shampoo bars and syndet bars.

SLMI generally offers greater flexibility in some liquid cleansing systems.

A manufacturer choosing between SCI and SLMI should consider:

• finished product format
• required foam profile
• processing temperature
• water compatibility
• viscosity target
• manufacturing equipment
• desired sensory profile

For some formulations, combining mild surfactants can provide a better result than relying on a single surfactant.

How Is Sodium Cocoyl Isethionate Used?

SCI is normally incorporated into a surfactant phase or solid cleansing base according to the formulation process.

Because SCI is a solid surfactant, processing is different from simply adding a liquid surfactant directly into water.

The appropriate method depends on:

• SCI particle size
• formulation type
• co-surfactants
• water content
• processing temperature
• mixing equipment
• desired final texture

For industrial production, pilot testing is recommended before increasing batch size.

Typical SCI Use Level

The appropriate SCI concentration depends strongly on the finished product.

Solid shampoo bars and syndet bars may contain substantially more SCI than liquid cleansing formulations.

Rather than relying on a universal percentage, formulators should determine the level according to:

• total active surfactant matter
• cleansing target
• product format
• co-surfactants
• skin and hair feel
• stability
• processing conditions

Please consult the current technical documentation when developing a commercial formulation.

Is Sodium Cocoyl Isethionate Sulfate-Free?

Yes. Sodium Cocoyl Isethionate is commonly used in sulfate-free personal care formulations.

SCI should not be confused with Sodium Lauryl Sulfate (SLS) or Sodium Laureth Sulfate (SLES).

The similarity of some surfactant names can cause confusion, but SCI belongs to a different chemical class.

This is one reason SCI is frequently selected for modern sulfate-free shampoo bars and mild cleansing products.

Bulk Sodium Cocoyl Isethionate Supply

For commercial manufacturers and ingredient distributors, purchasing SCI usually involves more than comparing a price per kilogram.
