Personal care applications
Hair care
Evaluate in shampoos and conditioners for wet combing, softness and creamy foam. Other listed applications include styling products, relaxers, bleaches, dyes and permanent-wave products.
Skin care and cleansing
Evaluate in body washes, bath gels, liquid soaps and shaving products for slip, rinse feel and foam. The supplier also lists creams, lotions, soap bars and deodorants.
Packaging and storage
125 kg or 200 kg PE drums, or a 1,000 kg IBC. Keep sealed in a cool, dry place away from strong oxidants. The supplier states a two-year shelf life under these storage conditions.
Grade selection and quotations
Compare ACPQ-72 and ACPQ-73 when the order requires a listed residual acrylamide limit of ≤ 1 ppm. If switching to the higher-solids ACPQ-74, compare at the same active-polymer level and confirm its grade-specific limits.
When requesting a quote, include Polyquaternium-7, the preferred grade, your application, estimated quantity and destination. Ask for the grade-specific TDS, SDS and a representative COA.
