Caprylyl Glycol can provide multiple formulation benefits.
As a skin-conditioning ingredient, it can contribute to a smoother and softer skin feel. COSMILE Europe identifies its skin-conditioning and emollient functions.
It can also support hair conditioning by contributing to the feel and manageability of hair.
In preservation systems, Caprylyl Glycol is frequently used alongside other antimicrobial ingredients. This allows formulators to develop preservation systems tailored to the formulation rather than relying on a single ingredient.
Caprylyl Glycol is particularly useful in skin-care products where a soft and smooth skin feel is desired.
Potential applications include:
COSMILE Europe specifically identifies Caprylyl Glycol as a skin-conditioning and emollient ingredient.
Caprylyl Glycol can also contribute to hair-conditioning performance.
COSMILE Europe describes hair-conditioning ingredients as materials that can improve hair feel, manageability, softness and appearance.
Potential applications include:
Caprylyl Glycol is commonly used in cosmetic preservation strategies as a multifunctional preservation-support ingredient.
It can be combined with other antimicrobial ingredients to improve the overall preservation system.
The exact preservation performance depends on:
The finished formulation should be evaluated using appropriate microbiological and preservation-efficacy testing.
COSMILE Europe identifies Caprylyl Glycol as a deodorising ingredient. It can help reduce or mask unpleasant body odours in suitable cosmetic formulations.
This functionality can be relevant to:
Caprylyl Glycol can appear as a clear liquid to waxy solid depending on temperature and commercial grade. A technical specification reports clear liquid to waxy solid, while another commercial COA describes colourless liquid to white semisolid.
For your liquid product, the SDP product specification can use:
Appearance: Clear, colourless liquid / Grade-specific
Commercial cosmetic grades commonly specify high purity. One technical data sheet specifies NLT 98.0% by GC, while another commercial COA reports 98.50% minimum and a test result of 99.29%.
The final SDP specification should follow the actual commercial grade COA/TDS.
A commercial technical specification reports a specific gravity of approximately 0.93 at 20°C, while another commercial COA reports a density range of 0.884–0.944 g/mL at 25°C.
Caprylyl Glycol has a melting point around 36–38°C, which explains why its physical form can change with temperature.
Commercial technical specifications may specify pH on an aqueous test solution. One technical data sheet reports pH 7–8 at 1% aqueous concentration.
The exact test method should be specified when publishing a numerical value.
Caprylyl Glycol has limited water solubility compared with highly water-soluble glycols. Its formulation behaviour depends on temperature, concentration and the other components present.
It can be incorporated into appropriate water or oil phases depending on the selected commercial grade and processing conditions.
Caprylyl Glycol should be incorporated according to the selected supplier's processing recommendations.
Because its melting point is near normal ambient temperatures, temperature control may be required when handling or incorporating certain grades.
Compatibility should be evaluated with:
Caprylyl Glycol should be stored in the original sealed packaging in a cool, dry and well-ventilated area according to the selected supplier's TDS/SDS.
Some commercial specifications recommend maintaining the material at or above room temperature because of its melting behaviour.
Caprylyl Glycol can be used in:
Commercial technical information also describes its use in creams, emulsions, shampoos, bath gels and other surfactant-based systems.
Caprylyl Glycol is a multifunctional cosmetic ingredient used for skin conditioning, emollient, hair-conditioning and deodorising functions.
The commonly assigned CAS number is 1117-86-8.
It can be supplied as a liquid, but its physical state is temperature-dependent because its melting point is around 36–38°C.
It can condition skin and hair, provide emollient properties, contribute to deodorising formulations and support suitable preservation systems.
It is commonly used as a preservation-support ingredient in cosmetic formulations. However, COSMILE Europe's listed cosmetic functions include skin conditioning, emollient, hair conditioning, deodorant and functional fragrance rather than a primary preservative function.
Yes. It is suitable for numerous skin-care formulations including creams, lotions, moisturizers and other emulsion-based products.
Yes. It can be used in shampoos, conditioners, hair treatments and other suitable hair-care systems.
Commercial and literature sources report values around 36–38°C, although the exact value is grade-dependent.
Commercial grades commonly have high purity. Representative specifications include NLT 98% by GC, but the exact requirement should follow the selected commercial grade COA/TDS.
Representative commercial specifications report approximately 0.93 g/mL at 20°C, with other grades specifying a broader density range.
