up&up Infant Toddler Liquid Laundry Detergent

An enzyme-powered laundry detergent formulated to tackle stubborn organic stains on children’s clothing, though its use of strong preservatives and fragrances may trigger sensitive skin.

Performance Rating: 8.8

The high 8.8/10 performance rating is driven by a robust and comprehensive cleaning system. It features a powerful blend of anionic and non-ionic surfactants, including sodium laureth sulfate, c12-15 alcohols ethoxylated, and sodium c10-16 alkylbenzenesulfonate to effectively lift grease and dirt. The formula is further boosted by protease and amylase enzymes which target stubborn protein and starch-based stains. Additionally, polyethyleneimine alkoxylated and sodium polyacrylate act as advanced soil-release and anti-redeposition polymers, while fluorescent brightener 5 ensures whites look brighter.

Safety Rating: 4.2

The low 4.2/10 safety rating is primarily due to several high-concern ingredients. Most notably, the combination of methylchloroisothiazolinone and methylisothiazolinone serves as a potent preservative system but is a well-known contact allergen and skin sensitizer. The formula also contains triethanolamine, which can pose respiratory and skin irritation risks, as well as synthetic fragrances which can trigger sensitivities. Furthermore, surfactants like sodium laureth sulfate carry risks of ethoxylation byproducts like 1,4-dioxane if not heavily purified.

Final Rating: 6.5

The overall 6.5/10 rating reflects a stark trade-off between exceptional cleaning power and significant skin safety concerns. While this detergent is highly efficient at removing tough stains and keeping laundry bright, it is not recommended for individuals with sensitive skin, eczema, or allergies due to the inclusion of harsh preservatives like methylchloroisothiazolinone and methylisothiazolinone, potentially irritating surfactants, and synthetic fragrances.

Verdict

This liquid laundry detergent represents a highly effective, stain-fighting formula designed to tackle the unique, heavy-duty cleaning challenges of baby, toddler, and family laundry. However, a deeper scientific look at its ingredient list reveals a stark contrast between its stellar cleaning performance and its suitability for highly delicate skin. On the performance front, the detergent is an absolute powerhouse. It utilizes a robust, multi-surfactant system featuring sodium laureth sulfate (SLES), C12-15 alcohols ethoxylated, and sodium c10-16 alkylbenzenesulfonate to break down greasy spills, dissolve sebum, and lift stubborn soils from fibers. This chemical lifting action is bolstered by a targeted dual-enzyme system: protease and amylase. Together, these biological catalysts actively digest tough organic proteins and starches, making quick work of baby formula, spit-up, pureed foods, and grass stains. To ensure these ingredients work at peak efficiency, biodegradable chelators like tetrasodium iminodisuccinate and builders like sodium citrate bind hard water minerals, while advanced anti-redeposition polymers like polyethyleneimine alkoxylated and sodium polyacrylate keep suspended dirt from settling back onto clean clothes during the wash cycle.these exceptional stain-lifting capabilities, the formulation raises significant red flags for sensitive skin—a highly ironic drawback given its typical marketing toward infants and toddlers. The primary concern is the preservative blend of methylisothiazolinone (MIT) and methylchloroisothiazolinone (CMIT). This combination is widely recognized by dermatologists as a potent contact allergen and sensitizer, capable of triggering contact dermatitis, hives, and severe itching when product residues linger on fabrics. The potential for skin irritation is further compounded by the inclusion of synthetic fragrances and fluorescent brightener 5 (an optical brightener designed to artificially make whites look brighter). Both additives are notorious irritants for eczema-prone or hyper-reactive newborn skin.conclusion, this detergent is an incredibly effective, budget-friendly option for stripping away tough, messy toddler stains and keeping everyday family laundry looking bright and fresh. However, it is far from a truly gentle or hypoallergenic formula. It is perfectly suited for older children and adults with normal skin, but parents of newborns or individuals with eczema, allergies, or sensitive skin barriers should strongly consider a truly dye-free, fragrance-free, and MIT/CMIT-free alternative.
