Description
Pentaerythrityl Tetraisostearate (PTIS) is a high-performance, oil-soluble cosmetic ester used as an emollient, pigment wetting agent, binder, and dispersing medium in lip products, foundations, color cosmetics, and anhydrous formulations.
Its rich, smooth sensory profile makes it particularly valuable in lipstick and make-up formulations where gloss, cushion, pigment dispersion, adhesion, and spreadability are critical performance parameters.
PTIS is supplied as a clear to pale-yellow viscous oily liquid and is suitable for professional cosmetic formulation, laboratory development, and small-to-medium scale manufacturing.

Key Formulation Benefits
High-Gloss Emolliency
Pentaerythrityl Tetraisostearate provides a rich and elegant emollient character that can improve the gloss, cushion, lubricity, and smooth application of lipsticks, lip glosses, balms, and other color cosmetic products.
Its ester structure contributes to a luxurious sensory profile while helping reduce the dry or draggy feel that may occur in highly pigmented formulations.
Pigment Wetting & Dispersion
PTIS is particularly useful as a pigment wetting and dispersing medium in color cosmetics.
Efficient pigment wetting can help improve:
- Pigment distribution
- Color uniformity
- Dispersion stability
- Pay-off
- Spreadability
- Surface smoothness
- Visual gloss
- Reduction of pigment agglomeration
This makes Pentaerythrityl Tetraisostearate especially suitable for formulations containing iron oxides, titanium dioxide, lakes, organic pigments, and other cosmetic colorants.
Improved Lipstick & Make-Up Texture
In lipstick and solid make-up systems, PTIS can contribute to improved cushion, glide, adhesion, and pigment binding, helping formulators balance structural waxes, pigments, powders, and liquid emollients.
It may also assist in producing a smoother, more uniform cosmetic film on application.
Typical Applications
Pentaerythrityl Tetraisostearate can be used in a wide range of cosmetic and personal-care formulations, including:
- Lipsticks
- Lip glosses
- Lip balms
- Liquid lip products
- Foundations
- Concealers
- Cream make-up
- Color cosmetics
- Pigment dispersions
- Anhydrous cosmetic systems
- Rich creams and emulsion oil phases
- Make-up sticks
- Cosmetic balms
Formulation Guidance
PTIS is normally incorporated into the oil phase of the formulation.
When used for pigment dispersion, pigments should be adequately wetted and dispersed into the ester using suitable laboratory or production equipment depending on pigment loading and required particle-size distribution.
For high-pigment systems, formulators should evaluate:
- Pigment wetting efficiency
- Dispersion quality
- Grind / particle distribution
- Viscosity
- Color development
- Pay-off
- Gloss
- Cushion
- Slip
- Film uniformity
- Long-term stability
The optimum use level depends on the complete formulation, pigment concentration, required sensory profile, and desired finished-product performance.
Pilot trials are recommended before production scale-up.
Why Use Pentaerythrityl Tetraisostearate?
PTIS is especially valuable where a formulation requires a combination of:
high gloss + rich emolliency + pigment wetting + smooth spreadability + improved cosmetic pay-off.
Unlike a simple carrier oil, PTIS can perform several roles simultaneously within a color cosmetic system, making it a useful formulation tool for professional lipstick, foundation, and pigment-dispersion development.
Compatibility & Development Considerations
Compatibility should be verified with the complete oil-phase system, including:
- Waxes
- Hydrocarbon emollients
- Esters
- Silicones
- Pigments
- Fillers
- Film-forming agents
- Structuring agents
Finished formulations should be evaluated for stability, pigment separation, syneresis, sweating, viscosity change, crystallization behavior, color uniformity, and packaging compatibility before commercialization.
