ProLipid™ 141 is a self-emulsifier from International Specialty Products (ISP). It is a lamellar system which provides benefits no other system
can deliver: outstanding moisturization, skin barrier strengthening,
uniform delivery of actives and product structuring. ProLipid&trade 141 also
provides exceptional aesthetics since high levels of oily materials feel
dry and silky when delivered from this lamellar gel.
ProLipid lamellar systems are the first of their type to deliver wide pH
compatibility, electrolyte tolerance, and stable rheology and
temperature profiles. To achieve these benefits, a balance of
components with overlapping functionalities was chosen.
ProLipid™ 141 is designed to provide a lamellar gel phase across a wide
range of pHs for formulation flexibility. At acidic pH, the lecithin is the
primary structuring agent. At neutral and basic pH, the fatty acids are
the primary structurants. The fatty alcohols and GMS promote
lamellar phase formation at all pHs.
ProLipid™ 141 lamellar gel system is a blend of well-studied and
globally-approved ingredients. Each constituent has been evaluated
for safety by expert committees worldwide and found to be safe and
suitable across a broad range of personal care applications and use
concentrations. There are no expected toxicity consequences from
exposure to either the individual constituents or the blend. Although
the blend has not been safety tested in animals, in clinically evaluated
moisturization and barrier assessments both irritation and
sensitization potential were assessed throughout the studies. None
was observed. These findings have been confirmed in Human
Repeated Insult Patch Testing, along with Human Phototoxicity and
Photoallergy Testing.
Formulation notes:
We recommend the use of a high shear mixer (or stick blender) or homogenizer to create emulsions with ProLipid 141 as this will optimize (reduce) the size of the droplets.
Recommended Use Level: 3 -5%, depending on the volume and composition of the oil phase
Recommended pH range: 3.8 – 8.0
To optimize (increase) temperature stability: Add low levels (0.1 – 0.2% of hydrocolloids)
Low-energy emulsification: Use gums or cellulosic thickeners, such as HEC, xanthan gum or magnesium aluminum silicate
Preservation system: Higher levels may be required
Materials to avoid: Dimethicone at greater than 0.5%
Appearance: Creamy White Flakes
INCI: Glyceryl Stearate (and) Behenyl Alcohol
Palmitic Acid (and) Stearic Acid (and) Lecithin (and) Lauryl Alcohol (and) Myristyl Alcohol (and) Cetyl Alcohol
