Propylene Glycol Dicaprylate Dicaprate

Product Description

Propylene Glycol Dicaprylate/Dicaprate is a high-purity, ultra-lightweight emollient diester derived from plant-based fatty acids. At ZHENYIBIO, our specialized factory utilizes advanced esterification and refining processes to produce a crystal-clear, odorless liquid with excellent spreadability. Known for its "dry-touch" feel and non-greasy texture, it is a superior alternative to traditional heavy oils in cosmetic formulations. As professional manufacturers, we ensure our product offers excellent skin compatibility and acts as an efficient solvent for active ingredients and UV filters. This versatile ingredient is highly sought after by global manufacturers of sunscreens, light lotions, and color cosmetics. As one of the most reliable suppliers in China, ZHENYIBIO provides consistent batch quality and full technical documentation (COA/MSDS). By sourcing directly from our factory, wholesale buyers benefit from competitive prices, high stability。

Function:

- Emollient:Propylene Glycol Dicaprylate Dicaprate may provide a smooth, silky and non-greasy feel, reduces transepidermal water loss and maintains skin hydration.

- Solvent & Dispersant: Propylene Glycol Dicaprylate/Dicaprate may dissolve lipophilic ingredients (e.g., sunscreens, pigments) and aids their uniform dispersion in formulations.

- Viscosity Regulator & Emulsifier: Propylene Glycol Dicaprylate/Dicaprate may adjust formulation viscosity and helps form stable emulsions, compatible with various surfactants.

- Pharmaceutical Excipient: Propylene Glycol Dicaprylate/Dicaprate may enhance solubility and oral bioavailability of poorly water-soluble drugs in lipid-based delivery systems.

FAQ

★What is Propylene Glycol Dicaprylate/Dicaprate?

It is a mixture of propylene glycol diesters of caprylic and capric acids. In cosmetics, it functions as a high-quality emollient and skin-conditioning agent, derived from vegetable sources (typically coconut or palm oil).

★What are its primary functions in skincare formulations?

It acts as a lightweight emollient that provides a smooth, non-greasy feel. It is widely used to improve the spreadability of creams and lotions and serves as an excellent solvent for UV filters in sunscreens.

★Is Propylene Glycol Dicaprylate/Dicaprate safe for skin?

Yes, it is considered safe for cosmetic use. The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated it and concluded that it is non-irritating and safe in the concentrations typically used in personal care products.

★How does it compare to Caprylic/Capric Triglyceride?

While both are derived from coconut/palm oil, Propylene Glycol Dicaprylate/Dicaprate usually has a lighter, "drier" skin feel and faster absorption rate compared to Caprylic/Capric Triglyceride (MCT oil).

★Is Propylene Glycol Dicaprate/Dicaprylate natural or synthetic?

It is a plant-derived synthetic ester. While the raw materials (fatty acids) are natural, the process of esterification makes it a "naturally derived" ingredient, which is favored in green and clean beauty formulations.

★What is the solubility of Propylene Glycol Dicaprylate/Dicaprate?

It is oil-soluble (lipophilic) and insoluble in water. It is an ideal carrier for oil-soluble active ingredients and essential oils, enhancing their penetration into the skin.

FAQs

How does ZHENYIBIO ensure the oxidative stability of whitening actives in water-based formulations?

We have developed a proprietary Anti-oxidation Stabilization System specifically designed for oxidation-prone active ingredients (such as glutathione). By controlling residual heavy metals in the raw materials—the primary catalysts for oxidation—and recommending a complementary chelating agent regimen, we ensure that the ingredients remain free from browning over extended periods within a pH range of 5.0 to 7.0.

Are your botanical brightening extracts compatible with high-concentration electrolytes?

Our plant extracts undergo a multi-stage refining process to remove the majority of inorganic salts and impurities; as a result, they exhibit excellent compatibility within serum formulations containing thickeners or high concentrations of electrolytes, without giving rise to flocculation or phase separation.

What technologies does ZHENYIBIO use to improve the skin penetration of plant-derived actives?

For large-molecule plant-derived active ingredients, we employ Liposomal Encapsulation and Micronization technologies. These techniques significantly reduce particle size, enabling active ingredients—such as Alpha-Arbutin—to more easily penetrate the stratum corneum and reach the areas where melanocytes are concentrated.

Can you provide In-vitro or In-vivo efficacy data for your whitening product line?

Yes. In addition to providing standard TDS documents, we can—upon request—supply data from Tyrosinase Inhibition Tests as well as Human Patch Test reports to support clinical claims regarding the "whitening efficacy" of your finished products.

Do ZHENYIBIO whitening ingredients meet the regulatory requirements of EU and North America?

Fully Compliant. Our products strictly adhere to both EU (Regulation EC No 1223/2009) and US MoCRA standards. A complete Certificate of Analysis (COA) is provided for every batch of raw materials, ensuring that levels of heavy metals, microbial contaminants, and residual solvents remain well below international regulatory limits.

Are your products "Clean Beauty" compliant (Vegan, Non-GMO, Cruelty-Free)?

Yes. As experts in Natural Plant Actives, we pledge that all our ingredients are derived from sustainable plant sources, contain no animal-derived components, involve no animal testing, and are accompanied by comprehensive traceability statements—empowering your brand to enter the clean beauty sector.

How do you guarantee a stable supply of botanical raw materials regardless of seasonal changes?

ZHENYIBIO maintains its own proprietary botanical cultivation bases. Through controlled environments and standardized harvesting processes, we are able to not only guarantee year-round stock availability but also ensure a high degree of consistency in the content of active ingredients—such as Glabridin—across different production batches.

Can ZHENYIBIO develop customized ingredient concentrations for specific brand requirements?

We can provide customized Standardized Extracts tailored to our clients' specific needs. Whether you require high-purity active monomers or blended ingredients in specific ratios, our R&D laboratory is equipped to make precise adjustments to meet your exact formulation requirements.
