Product Description:
VQ-PG silicone-hydrolyzed wheat protein is produced by reacting hydrolyzed plant protein with 3-epoxypropyltrimethyldihydroxy silane. VQ-PG combines the affinity of hydrolyzed plant protein (peptides) for hair and skin, along with their adsorption, moisturizing, and conditioning properties, with the gloss-enhancing and superior film-forming capabilities of silicone compounds. It readily forms a flexible, smooth protein film that coats the hair shaft, reducing split ends and improving hair appearance and combability. It is particularly effective in repairing damage to damaged hair and providing thermal protection. It effectively replenishes the loss of hair proteins and lipids, repairs damaged hair, and significantly enhances the moisturizing and conditioning performance of rinse-off products due to its stable water solubility.
INCI NAME:Hydrolyzed Vegetable Protein Pg-propyl Silanetriol
VQ-PG Hydrolyzed Vegetable Protein Pg-propyl Silanetriol liquid protein is a cutting-edge cosmetic ingredient that combines the nourishing benefits of plant-based proteins with the conditioning properties of silicone derivatives, making it a staple in modern personal care formulations. This liquid protein, known for its solubility and compatibility, has gained widespread recognition for its dual action on skin and hair, offering a natural and effective solution for enhancing appearance and health.
At its core, this ingredient is a modified hydrolyzed vegetable protein, where "hydrolyzed" refers to the breakdown of plant-based proteins into smaller amino acid chains through a reaction with water, often aided by enzymes. The addition of PG (propylene glycol) and propyl silanetriol—a trihydroxy silyl grouping related to silicone—creates a unique molecular structure that blends the nourishing power of proteins with the smoothing and protective benefits of silanes. Its liquid form ensures easy integration into various cosmetic products, from serums and lotions to shampoos and conditioners, without compromising texture or performance.
For hair care, VQ-PG Hydrolyzed Vegetable Protein Pg-propyl Silanetriol liquid protein excels as a conditioning agent. It penetrates the hair shaft to boost moisture content and plasticity, while also forming a protective coating on the hair cuticle to reduce friction and prevent damage. This dual action leaves hair soft, supple, easy to comb, and radiant, while also imparting volume and improving overall texture. Leading cosmetic brands, including L’Oréal, utilize this ingredient in hair care products to strengthen hair fibers and enhance manageability.
On the skin, this liquid protein serves as an effective skin conditioning agent, helping to maintain the skin in a healthy state by supporting its natural barrier function. It delivers essential amino acids that nourish the skin, promoting a smooth, hydrated complexion, and may also offer anti-aging benefits by improving skin elasticity and reducing the appearance of fine lines. Importantly, it is safe for use in cosmetic formulations, with established safe concentration limits—0.42% for leave-on products and 4.72% for rinse-off products—in China, where it is listed in the Catalogue of Used Cosmetic Raw Materials (2021 Edition).
Beyond its functional benefits, this liquid protein aligns with the growing demand for plant-based and sustainable cosmetic ingredients. Derived from plant sources, it offers a cruelty-free alternative to animal-based proteins, making it appealing to eco-conscious consumers. It is also free from major safety concerns, as it is not listed on the Environmental Working Group’s restricted or unacceptable ingredients lists.
In conclusion, VQ-PG Hydrolyzed Vegetable Protein Pg-propyl Silanetriol liquid protein is a versatile and effective cosmetic ingredient that bridges the gap between natural nourishment and advanced conditioning. Its unique composition, dual benefits for skin and hair, and compatibility with various formulations make it an invaluable addition to modern personal care products, catering to both performance and sustainability needs.
