LiquaPar Optima is a broad spectrum preservative used in a wide range of cosmetic products such as: creams, lotions, ointments, exfoliants, lipsticks, liquid and cream makeup, eyeliners, mascaras, etc. LiquaPar is perfect for products ranging from salt scrubs to toners to lotions and creams. Not to mention shampoo and liquid soap.
It is also non-volatile, remains fully stable over a wide pH and temperature range, is non-irritating to the skin, eyes, and mucous membranes, is devoid of skin sensitizing effects, is biodegradable, and presents no pollution hazard. Plus it is fully compatible with plant extract products and is effective as an antimicrobial preservative for aqueous herbal extracts and for cosmetic and pharmaceutical preparations containing plant products.
Owing to its many advantages, LiquaPar Optima is suitable for the preservation of topical pharmaceuticals and cosmetic and toiletry products of all types. Its powerful microbiocidal activity in most systems makes LPO effective in those products, which have been found especially difficult to preserve in the past (shampoos, lotions, creams, and protein-rich systems.) For preservative applications, LPO should be evaluated at concentrations of 0.5-1% depending on the conditions. ISP recommends a use level of not greater than 1%.
INCI Name: Phenoxyethanol (and) Methylparaben (and) Isopropylparaben (and) Isobutylparaben (and) Butylparaben
|I wish all preservative systems were as excellent by FormidibleFormulator on 2017-01-08 16:48:08|
|Rating:||5 of 5 - Excellent|
|Pros:||It's broad spectrum, works in both aqueous and oil-based solutions, works in pH ranges from 3 to 8 and isn't heat sensitive. It doesn't smell awful and doesn't tweak with emulsions. Is not a formaldehyde donor. In short, it's brilliant. Except...|
|Cons:||Parabens have a might be/might not be deserved cloud over them.|
|Comments:||Better a concern about whether parabens are of concern than the reality of microbial soup in high heats or a broken emulsion.|
