Dimethicone 100 cSt 250 g

Lightweight Non-Volatile Silicone for Skin, Hair & Cosmetic Formulations

Dimethicone 100 cSt is a clear, non-volatile silicone fluid widely used in skincare, hair-care, makeup and personal-care formulations.

Compared with higher-viscosity grades such as Dimethicone 350 cSt, the 100 cSt grade is:

• More fluid
• Easier to spread
• Lighter in sensory feel
• Easier to incorporate into many oil-phase systems

It can help improve:

• Slip
• Spreadability
• Smoothness
• Hair manageability
• Shine
• Softness
• Surface lubrication
• Sensory elegance

What Is Dimethicone 100?

Dimethicone is a polydimethylsiloxane silicone polymer.

The number 100 refers to its approximate viscosity:

100 centistokes (cSt)

This makes Dimethicone 100 less viscous than 350 cSt or 1,000 cSt grades, while still remaining non-volatile.

INCI Name: Dimethicone
Chemical Family: Polydimethylsiloxane
Typical Viscosity: Approximately 100 cSt
Form: Clear, Colorless Silicone Fluid
Primary Functions: Conditioning / Emollient / Spreading / Lubricity / Sensory Modification

Main Cosmetic Functions

Dimethicone 100 may be used to provide:

• Smooth application
• Silky skin feel
• Hair conditioning
• Improved slip
• Reduced friction
• Easier combing
• Improved shine
• Better product spreadability
• Reduced heavy or greasy feel

Its lower viscosity makes it especially useful where a lighter silicone feel is preferred.

Dimethicone 100 vs. Dimethicone 350

Both products belong to the same Dimethicone family but differ in viscosity.

Dimethicone 100 cSt

• More fluid
• Lighter sensory profile
• Faster spreading
• Easier distribution
• Suitable for lightweight serums and emulsions

Dimethicone 350 cSt

• More viscous
• Richer slip
• More substantial film
• Stronger persistent conditioning feel

The preferred grade depends on the desired texture and finished-product performance.

Is Dimethicone 100 Volatile?

No.

Dimethicone 100 is a non-volatile silicone.

It remains on the skin or hair after application and creates a smooth conditioning film.

It should not be confused with volatile silicones such as Cyclopentasiloxane.

Use in Skincare

Dimethicone 100 can be used in:

• Face creams
• Body lotions
• Hand creams
• Lightweight serums
• Primers
• Body-care products
• Barrier-support formulations

It can help improve:

• Spreadability
• Smoothness
• Slip
• Reduced tackiness
• Soft after-feel

Is Dimethicone a Moisturizer?

Dimethicone is not a humectant.

It does not attract water like:

• Glycerin
• Sorbitol
• Sodium PCA

Instead, it forms a light hydrophobic film that can help reduce excessive moisture loss and improve skin feel.

It is therefore more accurately described as an:

• Emollient
• Skin-conditioning ingredient
• Film-forming silicone

rather than as a primary moisturizer.

Use in Hair Care

Dimethicone 100 is particularly useful in:

• Hair serums
• Conditioners
• Hair masks
• Leave-in products
• Anti-frizz products
• Shine products
• Styling formulations

It can help improve:

• Detangling
• Wet combing
• Dry combing
• Smoothness
• Shine
• Softness
• Manageability

Hair Surface Conditioning

Dimethicone forms a thin film over the hair fiber.

This can help reduce friction and give the hair a smoother and more uniform appearance.

It does not permanently repair damaged hair but may improve the appearance and feel of damaged or rough hair.

Use in Hair Serums

Dimethicone 100 is well suited to lightweight silicone-based hair serum formulations.

Its lower viscosity compared with Dimethicone 350 makes it useful where faster spreading and a less heavy finish are desired.

It may be combined with compatible ingredients such as:

• Other Dimethicone grades
• Dimethiconol
• Cosmetic esters
• Lightweight emollients
• Approved fragrance materials

depending on formulation goals.

Use in Shampoos

Dimethicone can be used in shampoo formulations, but neat Dimethicone 100 is not water-soluble.

It generally requires:

• Appropriate emulsification
• Silicone dispersion technology
• Pre-emulsified silicone
• Compatible surfactant system

Direct addition to a shampoo without adequate dispersion may result in separation.

Use in Conditioners

Dimethicone 100 may be incorporated into properly emulsified:

• Rinse-off conditioners
• Hair masks
• Leave-in conditioners

to improve slip, combability and softness.

Use in Makeup

Dimethicone 100 is also useful in:

• Primers
• Foundations
• BB creams
• Concealers
• Cream makeup
• Lip products

It can help provide:

• Smooth application
• Improved spreadability
• Silky finish
• Reduced tackiness
• Better glide

Use in Sunscreen Formulations

Dimethicone 100 may be used in sun-care formulations to improve:

• Spreadability
• Water repellency
• Sensory feel
• Film formation

However:

Dimethicone is not a UV filter.

It does not provide SPF, UVA or UVB protection by itself.

Any sunscreen claim must rely on permitted UV filters and validated finished-product testing.

Use in Soap Making

Dimethicone 100 is not a conventional soap-making ingredient.

Traditional soap is produced by reacting fats and oils with sodium hydroxide or potassium hydroxide.

Dimethicone does not participate in the saponification reaction.

It does not replace:

• Soap-making oils
• NaOH
• KOH
• Correct SAP calculations

Cold Process Soap

Routine use of Dimethicone 100 in cold process soap is generally unnecessary.

Silicone fluids may also reduce foam in some systems.

If used experimentally:

• Keep dosage low.
• Test compatibility.
• Monitor lather.
• Evaluate bar hardness.
• Evaluate skin feel.

Do not assume it will automatically improve traditional soap performance.

Melt & Pour Soap

Small experimental amounts may be evaluated in selected melt and pour bases.

Excess Dimethicone may affect:

• Lather
• Clarity
• Hardness
• Surface feel
• Base stability

Always follow the soap-base manufacturer’s recommended additive limits.

Typical Usage Levels

General formulation starting ranges may include:

Creams & Lotions

0.5–5%

Hair Conditioners

0.5–3%

Hair Serums

1–10%

Makeup Products

0.5–5%

Selected Cleansing Products

Use at low levels depending on the surfactant system and silicone dispersion technology.

These are formulation starting ranges rather than universal limits.

Always follow the supplier TDS for the actual grade.

Oil & Water Compatibility

Dimethicone 100 is:

Insoluble in water

and compatible with many:

• Silicone fluids
• Cosmetic esters
• Oil-phase ingredients
• Anhydrous systems

Water-containing formulations require an appropriate emulsification or dispersion system.

Antifoaming Effect

Dimethicone can have antifoaming properties.

This may be useful in some industrial formulations but undesirable in products where rich foam is expected.

Use cautiously in:

• Shampoo
• Body wash
• Foaming cleanser
• Liquid soap
• Traditional soap

High concentrations may reduce foam.

pH Information

Dimethicone 100 is an anhydrous silicone fluid.

A statement such as:

pH 5.0–7.0

is therefore not particularly meaningful for the raw material.

The pH of the complete water-containing formulation should instead be measured.
