What is Poly(Acrylic acid)?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Poly(Acrylic acid) which has developed particularly rapidly in recent years. Do you know about Poly(Acrylic acid)?
This product is a polymer of acrylic acid bonded to allyl sucrose or pentaerythritol allyl ether. On a dry basis, the carboxylic acid group (-COOH) should be 56.0%-68.0%.5
What’s the application of Poly(Acrylic acid)?
Emulsifier
Effective at very low concentrations – 0.1-0.5%, replacing conventional surfactant dosages of 3-7%
Unrestricted by HLB value and PlT
Emulsifies any liquid oil at room temperature
Emulsifies waxes if waxes are melted in the manufacturing process
Take full advantage of the wetting, dispersing and adhesion effects of surfactants to produce stable emulsions
Does not re-emulsify when re-wetting, making it easy to prepare water-resistant emulsions without film-forming agents
Can be used to form (o/w) emulsions by dissolving the high oil phase in water
For the preparation of moisturising creams, lotions, facial cleansers, sunscreens, alcohol-free perfumes, fragrant hair conditioners (for shine and combability), hand wash
emulsions, low consistency sprayable emulsions and clear microemulsions. One method is to add a carbomer to an oil phase system to slow down the rate of swelling, the so-called indirect method, but this depends on the formulation. Carbomer is not very sensitive to changes in the addition process.
Used in skincare products
Hydrophilic thickeners, stabilising emulsifiers, suspending agents, gelling agents, good clarity, need to maintain a medium to weak alkalinity to have consistency, therefore cannot co-exist with acidic active ingredients, in addition, Carbomer is also afraid of salts, therefore cannot add mineral ions, otherwise, the consistency will disappear, irritating to the eye mucosa. Carbopol is the name given by the manufacturer of the ingredient, most of which are numbered Carbomer, but not all. [Irritating, non-comedogenic].
