Polyquaternium-39, a well - known conditioning polymer, has found its way into a wide range of hair care products. As a supplier of Polyquaternium - 39, I often receive inquiries from customers, especially those in the hair care industry, about its suitability for products targeting oily hair. In this blog post, I'll delve into the scientific aspects of Polyquaternium - 39 and explore whether it can be effectively used in products for oily hair.
Understanding Polyquaternium - 39
Polyquaternium - 39 is a synthetic polymer that belongs to the family of quaternary ammonium compounds. It is formed through the copolymerization of vinylpyrrolidone, dimethylaminoethyl methacrylate, and methacrylamidopropyl trimethylammonium chloride. This unique chemical structure gives Polyquaternium - 39 several beneficial properties for hair care.
One of the primary functions of Polyquaternium - 39 is its conditioning ability. It forms a thin, positively - charged film on the hair shaft. Since hair typically has a negative charge, the positive charge of Polyquaternium - 39 allows it to adhere strongly to the hair. This film helps to smooth the cuticle, reduce frizz, and improve the overall manageability of the hair. It also enhances the shine and softness of the hair, making it look and feel healthier.

The Challenge of Oily Hair
Oily hair is a common problem that many people face. It is mainly caused by the over - production of sebum, an oily substance secreted by the sebaceous glands in the scalp. Sebum helps to lubricate the hair and scalp, but when too much is produced, it can make the hair look greasy, limp, and unkempt.
When formulating products for oily hair, the key is to balance cleansing and conditioning. A good oily - hair product should be able to remove excess sebum effectively while still providing enough moisture and protection to prevent the hair from becoming dry and brittle. At the same time, it should not add additional weight or greasiness to the hair.
Can Polyquaternium - 39 Be Used for Oily Hair?
The answer is yes, but with careful consideration. On one hand, Polyquaternium - 39 offers several advantages for oily - hair products. Its conditioning properties can help to counteract the dryness that can sometimes occur after using strong cleansing agents on oily hair. By smoothing the cuticle, it can also make the hair appear cleaner and more voluminous, as frizzy and unruly hair can give the illusion of greasiness.
However, there are also potential drawbacks. If used in too high a concentration, Polyquaternium - 39 can build up on the hair over time, adding weight and making the hair look even oilier. This is because the polymer film it forms can trap sebum and other impurities on the hair. Therefore, the concentration of Polyquaternium - 39 in products for oily hair needs to be carefully optimized.
Comparison with Other Polyquaterniums
To better understand the suitability of Polyquaternium - 39 for oily hair, it's useful to compare it with other common polyquaterniums, such as Polyquaternium - 6 and Polyquaternium - 7.
Polyquaternium - 6 is a homopolymer with a relatively high charge density. It is known for its excellent conditioning and antistatic properties. However, it can also be quite heavy and may not be the best choice for oily hair, especially in high concentrations.
Polyquaternium - 7, on the other hand, is a copolymer that is more water - soluble and has a lighter feel. It can provide good conditioning without adding too much weight to the hair. In some cases, it may be a better option for oily - hair products compared to Polyquaternium - 6.
Compared to these two, Polyquaternium - 39 strikes a balance between conditioning and weight. Its unique chemical structure allows it to provide effective conditioning while being less likely to cause excessive build - up compared to Polyquaternium - 6, especially when used in appropriate concentrations.
Formulating Oily - Hair Products with Polyquaternium - 39
When formulating hair care products for oily hair with Polyquaternium - 39, several factors need to be considered.
Concentration: As mentioned earlier, the concentration of Polyquaternium - 39 should be carefully controlled. A lower concentration, typically in the range of 0.1% - 1%, is usually recommended for oily - hair products. This can provide enough conditioning benefits without adding too much weight to the hair.
Combination with Other Ingredients: Polyquaternium - 39 can be combined with other ingredients that are beneficial for oily hair. For example, it can be used in conjunction with cleansing agents such as sodium laureth sulfate or cocamidopropyl betaine to remove excess sebum. It can also be paired with ingredients like salicylic acid, which has anti - sebum and exfoliating properties, to help keep the scalp clean and reduce sebum production.
Product Type: The type of product also matters. In shampoos for oily hair, Polyquaternium - 39 can be used to provide some conditioning during the cleansing process. In conditioners, it can be used in a more diluted form to give a light conditioning effect without weighing down the hair.
Case Studies
There have been several successful case studies of using Polyquaternium - 39 in oily - hair products. For example, a leading hair care brand developed a shampoo for oily hair that contained a low concentration of Polyquaternium - 39. The product was well - received by consumers, as it effectively removed excess sebum while leaving the hair feeling soft, smooth, and voluminous. Another brand used Polyquaternium - 39 in a leave - in treatment for oily hair. The treatment was formulated to be light and non - greasy, and it helped to control frizz and improve the overall appearance of the hair without adding any additional oiliness.
Conclusion
In conclusion, Polyquaternium - 39 can be a valuable ingredient in products for oily hair when used correctly. Its conditioning properties can help to improve the appearance and manageability of oily hair, while careful formulation can prevent it from adding excessive weight or greasiness.
