Dilinoleamidopropyl PG is a type of mild, non-ionic conditioning agent derived from natural linoleic acid and propylene glycol derivatives. It is synthesized through a series of amidation reactions, which endow it with excellent compatibility, moisturizing properties and conditioning effects. Unlike some cationic conditioning agents that may cause buildup on hair or skin, this ingredient is characterized by its lightweight texture and high affinity for biological surfaces, making it widely used in high-end personal care and cosmetic formulations.

In terms of physical properties, dilinoleamidopropyl PG typically appears as a pale yellow to light brown viscous liquid at room temperature, with a faint, natural fatty acid-derived odor. It has good solubility in both water and common cosmetic oils, enabling it to integrate seamlessly into various water-based, oil-based and emulsion systems without causing phase separation or turbidity. It also exhibits stable performance across a wide pH range, from weakly acidic to weakly alkaline, and maintains its efficacy even under high-temperature processing conditions, which is ideal for the production of cosmetics and personal care products.

Dilinoleamidopropyl PG is highly valued in hair care products for its outstanding conditioning effects. When applied to hair, it can penetrate the hair cuticle and adsorb gently on the hair surface, filling the gaps in damaged hair scales caused by chemical treatments such as perming, dyeing or frequent heat styling. This action helps to reduce friction between hair strands, preventing tangling, frizzing and breakage during combing.

Moreover, it forms a lightweight, non-greasy protective film on the hair, which locks in moisture and prevents water loss from the hair shaft. Regular use of products containing this ingredient can make hair softer, smoother and more lustrous, while improving the hair’s manageability without weighing it down. It is particularly suitable for dry, damaged and frizzy hair types, as it can restore the hair’s natural healthy state.

For skin care applications, dilinoleamidopropyl PG acts as an efficient moisturizer and emollient. It can penetrate the stratum corneum, supplement the skin’s natural lipid components, and enhance the skin’s moisture-retention capacity. This helps to alleviate skin dryness, roughness and tightness, leaving the skin feeling soft, supple and hydrated.

Unlike heavy emollients that may clog pores, this ingredient has a lightweight texture that is easily absorbed by the skin, making it suitable for all skin types, including sensitive and oily skin. It also helps to improve the texture of skin care products, making lotions, creams and body washes more spreadable and comfortable to apply, with no sticky residue left on the skin surface.

One of the key advantages of dilinoleamidopropyl PG is its excellent compatibility with other cosmetic ingredients. It can be compounded with cationic, anionic and non-ionic surfactants, thickeners, preservatives and active ingredients without causing adverse reactions such as precipitation or stratification. This flexibility allows formulators to incorporate it into a wide range of products, from shampoos and conditioners to facial moisturizers, body lotions and baby care products.

Additionally, it helps to stabilize emulsion systems, reducing the risk of phase separation in cosmetic products during storage and extending their shelf life. Its mild nature also ensures that products containing this ingredient have low irritation potential, making them safe for long-term use.
