ACUSOL OP 301 imparts a milky, lotionized appearance to a wide variety of household liquid products.
ACUSOL OP301 Opacifier is an aqueous styrene/acrylic emulsion designed for opacifying home and institutional care products.
The polymer is used to impart a milky or lotionized appearance to a liquid product, generally at addition levels of 0.1 to 1.0%.
ACUSOL OP301 Opacifier is offered at 40% solids and is compatible with most ingredients present in home and institutional care products.
The polymer is safe in normal use.
ACUSOL OP301 opacifier is a water-based, styrene/acrylic emulsion used for opacifying personal care, household and institutional products including shampoos, bath and shower gels, laundry and dishwashdetergents, and household cleaners.
A liquid detergent aqueous composition comprising a mono-alcohol and an opacifier wherein the opacifier has improved stability in ethanol versus Acusol 301 and wherein the opacifier preferably is a high order polymer.
ACUSOL OP301 Opacifier imparts a milky, lotionized appearance to a wide variety of household liquid products.
ACUSOL opacifiers are water-based styrene/acrylic emulsions that have been designed to scatter light effectively.
These products are offered at pH values between 2 and 5 and may require neutralization.
ACUSOL OP301 Opacifier polymer is synthesized from styrene and acrylate comonomers and is made through emulsion polymerization.
Behavior Profile of ACUSOL Opacifiers:
Corrosion Resistance
Tests have been performed for corrosion resistance under several different conditions on ACUSOL OP301 Opacifier as representative of the ACUSOL opacifier range.
In the presence of a 304L stainless steel coupon heated to “sensitizing” temperature, no visible corrosion was noted nor was any change in product color observed, even at 60˚C for 378 hours.
The same results were obtained using 304L and 316L stainless steel coupons with welds present.
Microbial Resistance
ACUSOL OP301 Opacifier has a pH of 2.05 to 2.5 and is inherently not susceptible to microbial contamination.
Random checks are carried out throughout the year to help ensure that there are no detectable microorganisms in the product.
If ACUSOL OP301 Opacifier is stored diluted, then it must be suitably preserved.
Formulation Use and Guidelines:
Order of Addition
ACUSOL OP 301 is recommended that the ACUSOL opacifiers be added last in the manufacturing cycle, after addition of dye, salt, perfume, etc. and following final pH adjustment.
To avoid potential“shock” the product should be diluted with at least four times its own weight of product water (held out from the formulation), then added very slowly to the final mix, maintaining good agitation throughout the addition process.
Stability Testing
Stability testing should be carried out on all opacified products.
Four week stability tests under the following conditions are recommended:
1. Room temperature (20 to 25°C)
2. Oven (40°C)
3. Cold (4 to 6°C)
4. Freeze/thaw, 3 cycles
Formulation Use and Guidelines of ACUSOL OP 301:
Stability in Formulations of ACUSOL OP 301:
ACUSOL opacifiers offer excellent formulation stability.
The following guidelines are provided to optimize their performance in this regard.
If ACUSOL opacifiers are being formulated with anionic surfactant systems, it may be necessary to add 1 to 3% of a hydrotrope (e.g.propylene glycol, isopropanol or sodium xylene sulphonate) to increase the solubility/compatibility of the surfactants at colder temperatures.
Without the added hydrotrope, the anionic surfactants may have decreased solubility at lower temperatures and can crystallize out of solution, causing the ACUSOL opacifiers to precipitate as well.
If ACUSOL opacifiers are being formulated with nonionic surfactants at warm temperatures, the formation of water insoluble, nontransparent droplets may result (cloud point).
If a cloud point is observed, try selecting a surfactant with more ethylene oxide/ethoxylate groups (> 15) and possessing a higher HLB - hydrophilic/hydrophobic (lipophilic)
balance value. Other suggestions include increasing the concentration of nonionic or presolubilizing the fragrance in a pre-warmed nonionic surfactant.
If instability of a formulation containing ACUSOL opacifiers is observed at both cold and warm temperatures, check the compatibility of the opacifier with the other ingredients in the formulation such as cationic surfactants, solvents and oxidizing agents.
Then try using the suggested solutions listed above.
In all cases, it is important to follow the recommended addition sequence when using ACUSOL opacifiers to ensure their optimum performance.
ACUSOL opacifiers be cleaned with high pressure washing or the use of the following cleaning solution:
(1) 90 parts water
(2) 2.5 parts Sodium Lauryl Ether Sulfate (SLES) (27%)
(3) 2.5 parts nonionic surfactant (e.g. alcohol ethoxylate alternative)
(4) 5 parts sodium hydroxide (25%) or monoethanolamine (90%)
Handling Precautions of ACUSOL OP 301:
Product safety information required for safe use is not included in this document.
Before handling, read product and safety data sheets and container labels for safe use, physical and health hazard information.
Usable Life and Storage of ACUSOL OP 301:
Keep from freezing; material may coagulate.
The ACUSOL opacifiers are not freeze/ thaw stable and should therefore be kept at temperatures of 5 to 35°C. If kept under these conditions and in their unopened containers, the products will have a shelf life of 18 months or greater from the date of manufacture.
If the ACUSOL opacifiers are stored diluted, then they must be suitably preserved.
