With the emphasis on personal hygiene and skin care, wet wipes have become a regular item in households, maternal and child care, medical care and daily traveling. In order to enhance the use experience and skin care effect of wipes, a variety of functional ingredients are often added to the formulations. Among them, Polyquaternium-7 is one of the most popular additives in wipes due to its good thickening, skin friendliness and mildness.
What is Polyquaternium-7?
Polyquaternium-7 is a water-soluble cationic polymer copolymerized with acrylamide and the cationic monomer dimethyldiallylammonium chloride (DADMAC). It is colorless and transparent, low irritation, with good water solubility and formulation compatibility.
The role of polyquaternium-7 in wet wipes
1. Gentle thickening, stabilize the liquid system
Liquid formulations in wet wipes often include water, moisturizers, cleaning ingredients, etc. If the liquid is too thin, it is easy to affect the sense of use of wet wipes. Polyquaternium-7 has good thickening and viscosity adjustment function, even at low concentrations can improve the consistency of the solution, so that the liquid is not easy to drip, uniform distribution, while not producing greasy or sticky feeling, more comfortable and refreshing to use.
2. Enhance skin affinity and moisturizing properties
Polyquaternium-7 is a cationic ingredient that adsorbs with the negatively charged stratum corneum on the surface of the skin to form a soft protective film on the skin. This film reduces water loss and enhances skin moisturization and smoothness, making it particularly suitable for use in demanding products such as wipes for infants, sensitive skin and post-operative care.
3. Reduced irritation and improved mildness
Compared with some traditional moisturizers or preservatives, polyquaternium-7 has low irritation and allergy risk, which can enhance the overall mildness of the wipes' formulations, and help brands to create “skin-friendly” and “hypoallergenic” product selling points.
4. Synergistic stabilization to enhance the performance of other ingredients
Polyquaternium-7 has good compatibility with a variety of common ingredients (such as glycerin, propylene glycol, surfactants), which can stabilize the system, extend the shelf life of the product, and enhance the texture of the product.
Applicable types and recommended dosage of wipes
Polyquaternium-7 is suitable for the following types of wipes:
Baby wipes / adult wipes
Medical wipes
Makeup remover wipes / Facial cleansing wipes
Pet wipes
The recommended additive level is generally 0.05% ~ 0.5%, which can be fine-tuned according to the formulation system and the target sense of use.
Summary
Polyquaternium-7 is an important functional raw material in the formulation of modern wet wipes, as it not only brings good handfeel and skin comfort to the wipes, but also enhances the overall stability and mildness of the product.
