Propylene Glycol Dicaprylate is an ester-based cosmetic ingredient used primarily as an emollient and skin-conditioning agent in personal care formulations. It helps improve skin feel, lubrication, and spreading characteristics, making it useful in products designed for smooth application and a comfortable finish.
This ingredient can be evaluated for moisturizers, facial creams, lotions, makeup products, body care formulations, cleansing products, and other compatible cosmetic applications. Its lipophilic character makes it suitable for oil-containing formulations where water solubility is not required.
Propylene Glycol Dicaprylate can be incorporated alongside other emollients, oils, waxes, emulsifiers, and functional ingredients to help formulators achieve the desired texture and sensory performance. Its exact contribution to the finished product depends on the grade, concentration, formulation composition, and processing conditions.
Propylene Glycol Dicaprylate is a fatty acid ester associated with propylene glycol and caprylic acid. Caprylic acid is an eight-carbon saturated fatty acid. Esterification produces an ingredient with oil-compatible characteristics that are useful in cosmetic and personal care formulations.
Its INCI name is Propylene Glycol Dicaprylate. The ingredient is generally used for emolliency, skin conditioning, and lubrication. It may be considered for both anhydrous formulations and the oil phase of suitable emulsions.
Unlike mixed caprylate/caprate ingredients, Propylene Glycol Dicaprylate is associated specifically with caprylic acid ester components. However, the exact composition and physical properties of a commercial grade should be verified through its technical data sheet (TDS) and certificate of analysis (COA).
1. Emollient Performance
Propylene Glycol Dicaprylate helps soften the skin surface and improves the sensory properties of cosmetic formulations. It can contribute to a smooth and conditioned skin feel.
2. Improved Spreadability
Its lubricating characteristics can help a cosmetic product spread more evenly during application. This can be useful in creams, lotions, and selected makeup products.
3. Skin Conditioning
The ingredient supports the conditioning characteristics of personal care formulations. It can be combined with other emollients to achieve the desired softness, glide, and after-feel.
4. Oil-Phase Compatibility
Its lipophilic nature makes it suitable for oil-based formulations and the oil phase of emulsions. It can be evaluated alongside other compatible oils, esters, waxes, and oil-soluble ingredients.
5. Sensory Modification
Propylene Glycol Dicaprylate can contribute to the sensory profile of the finished product. The resulting texture, gloss, and residual feel depend on the overall formulation rather than the ester alone.
6. Formulation Versatility
It may be considered for skin care, body care, makeup, and selected personal care products, subject to ingredient-grade suitability and formulation testing.
Propylene Glycol Dicaprylate is generally incorporated into the oil phase of cosmetic formulations. Follow the handling and processing recommendations supplied for the specific commercial grade.
Commercial grades may vary in physical properties and quality parameters. Do not assume that specifications for Propylene Glycol Dicaprylate/Dicaprate apply to Propylene Glycol Dicaprylate.
When evaluating Propylene Glycol Dicaprylate for cosmetic manufacturing, consider the following quality and procurement requirements:
Product identity and grade-specific properties should be verified before the material is approved for production.
Propylene Glycol Dicaprylate is an ester-based cosmetic ingredient used to improve emolliency, lubrication, and skin feel in suitable personal care formulations. It can be evaluated for moisturizers, lotions, body care products, makeup, and other compatible cosmetic applications.
Before commercial use, manufacturers should confirm the supplied grade's identity, composition, technical specifications, and compatibility with the finished formulation. Laboratory trials and appropriate stability testing are recommended before scaling up production.
1. What is Propylene Glycol Dicaprylate?
Propylene Glycol Dicaprylate is a fatty acid ester used primarily as an emollient and skin-conditioning ingredient in cosmetic and personal care formulations.
2. What is the CAS number of Propylene Glycol Dicaprylate?
CAS 58748-27-9 is associated with this ingredient in some references. Verify the correct identifier against the specific commercial grade before publication.
3. What is the molecular formula of Propylene Glycol Dicaprylate?
The molecular formula for the fully esterified dicaprylate structure is C₁₉H₃₆O₄.
4. What is the molecular weight of Propylene Glycol Dicaprylate?
The molecular weight of the fully esterified dicaprylate structure is approximately 328.49 g/mol.
5. Is Propylene Glycol Dicaprylate soluble in water?
It is generally insoluble or poorly soluble in water because of its lipophilic ester structure.
6. What is Propylene Glycol Dicaprylate used for in cosmetics?
It is used for emolliency, skin conditioning, lubrication, and improved spreading in suitable personal care formulations.
7. Can Propylene Glycol Dicaprylate be used in creams and lotions?
It may be incorporated into the oil phase of compatible creams and lotions, subject to formulation and stability testing.
8. Is Propylene Glycol Dicaprylate the same as Propylene Glycol Dicaprylate/Dicaprate?
No. The names describe different ingredient identities. The latter refers to a mixed caprylic/capric ester ingredient, while Propylene Glycol Dicaprylate refers specifically to the dicaprylate structure.
9. How should Propylene Glycol Dicaprylate be stored?
Follow the storage recommendations in the current supplier documentation and keep the container properly closed.
