4-PCA Diphenyl Dimethicone is an inorganic chemical compound derived from dimethicone.
The name describes the structure of the molecule:
- 4-PCA (Pyroglutamic Acid) is an organic compound derived from glutamic acid, an amino acid. It is known for its moisturizing properties and is often used in skin and hair care products.
- Diphenyl Dimethicone is a type of silicone with emollient and conditioning properties. It acts by forming a protective film on the skin or hair, improving softness and manageability.
Raw Materials Used in Production.
4-PCA Diphenyl Dimethicone is a synthetic compound derived from a chemical reaction involving Diphenyl Dimethicone, a type of silicone, and 4-PCA (4-Pyridinocarboxylate). The latter is a derivative of pyridine, an organic chemical substance.
Step-by-step Summary of Industrial Production Process.
- Synthesis of Diphenyl Dimethicone through controlled chemical processes.
- Preparation of 4-PCA.
- Reaction of Diphenyl Dimethicone with 4-PCA to form 4-PCA Diphenyl Dimethicone.
- Purification of the product to remove impurities and by-products.
- Quality control to ensure purity and compliance with specifications.
Form and Color
4-PCA Diphenyl Dimethicone typically appears as a clear, viscous liquid.

What it is used for and where
Cosmetics
Skin conditioning agent - Emollient. Emollients have the characteristic of enhancing the skin barrier through a source of exogenous lipids that adhere to the skin, improving barrier properties by filling gaps in intercorneocyte clusters to improve hydration while protecting against inflammation. In practice, they have the ability to create a barrier that prevents transepidermal water loss. Emollients are described as degreasing or refreshing additives that improve the lipid content of the upper layers of the skin by preventing degreasing and drying of the skin. The problem with emollients is that many have a strong lipophilic character and are identified as occlusive ingredients; they are oily and fatty materials that remain on the skin surface and reduce transepidermal water loss. In cosmetics, emollients and moisturisers are often considered synonymous with humectants and occlusives.
Solvent. It is the substance for dissolving or dispersing surfactants, oils, dyes, flavourings, bactericidal preservatives in solution.
Commercial Applications
Primarily used in cosmetic and skincare products, especially as a conditioning agent. It offers benefits such as improved product spreadability, silky feel on the skin, and enhanced stability of cosmetic formulations.
Safety
Dimethicone is a chemical compound, derived from silicone, a mixture of linear methylated siloxane polymers, a chemically inert silicone-based polymer. It is considered safe when formulated to be non-irritating in cosmetic products.
