This page summarizes the technical insights shared in this post by user Caramel Please, expanded with broader Australian detergent chemistry, dosing principles, formulation types, and the limitations of testing by Choice and other review bodies.

Australia has high-quality detergents—it’s difficult to buy a truly ineffective one from Woolworths or Coles. Most are formulated for performance at approximately 20 °C and above, so in most regions, tap-cold washing works year-round.

Many Australians do not need to understand laundry chemistry because even surfactant-only detergents can clean typical human grime. However, label instructions often cause overdosing, which “brute-forces” cleaning through excess product rather than chemistry. If detergents were dosed correctly for machine type, quality differences between brands would become more obvious.

Blanket rules such as “two tablespoons per load” are inaccurate. Dosing depends on several interrelated factors.

* Front loaders: Use less water, giving higher detergent concentration; use less product overall. * Top loaders (agitator): Use higher fill levels, diluting detergent and minerals more; require more detergent. * HE top loaders (impeller): Sit between the two in water use and detergent needs.

Calcium and magnesium ions consume detergent. * Soft water: Easier sudsing, lower detergent requirement. * Hard water: Fewer suds, higher detergent requirement.

Label doses usually assume a 7–8 kg load. Front-loader capacities are physically smaller than same‑rated top loaders. More clothes mean more grime and minerals, both of which consume detergent.

* Visual: Aim for thin “trace suds,” not a bubble bath. Overdosing leaves grime behind. * Finger test: After five minutes of agitation, water should feel slippery enough that snapping fingers is hard. * Modern detergents may include anti‑foam agents; low foam does not always mean underdosing.

Hotter water improves reaction speed and sebum removal (around body temperature or higher). Most Australian detergents include cold‑active surfactants and enzymes, so they still perform well in cold water.

Contain multiple surfactants to cover a broad range of stains, including mechanical grease. Liquids are less stable, limiting concentration. Pods use multi‑chamber designs that allow more surfactants, enzymes, and superior water conditioners.

Contain fewer but stronger surfactants targeting specific soils. They are generally weaker on grease yet excel on oxidation‑sensitive stains. Powders can stably include oxygen bleach and strong builders, using precipitating conditioners that may leave faint residues but rinse cleanly.

Water conditioners allow surfactants to work despite minerals:

* Powders: Use *precipitating builders* that bind calcium/magnesium into insoluble complexes—effective but brute‑force. * Liquids/Pods: Use *non‑precipitating builders* that wrap minerals and keep them dissolved for a cleaner rinse, though less effective in very hard water and more expensive to formulate.

Enzymes dramatically improve soil breakdown, yet many Australian detergents omit them. The UK’s “bio vs. non‑bio” distinction persists here, and Unilever removes enzymes from sensitive lines like OMO Sensitive. Enzyme stability increases cost, so cheaper detergents often include only protease and amylase.

* Lipase: Fats, sebum, oils, butter—critical for body soil removal. * Protease: Protein stains (blood, dairy, egg, human grime). * Amylase: Starch from pasta, rice, sauces. * Mannanase: Gums/thickeners in foods or cosmetics. * Cellulase: Fabric‑care enzyme; revives textiles and reduces greying. * Pectinase: Fruit and tomato‑based stains.

* β‑Acetylglucosaminidase: Loosens old, dried stains by breaking biological “glue.” * DNase: Attacks extracellular DNA in grime, boosting deodorisation.

True oxygen bleach, sodium percarbonate, exists only in powders. “Oxi” liquids/pods rarely include true bleach—it’s a marketing term for surfactant/oxidiser blends.

* Releases oxygen radicals that de‑colour stain molecules without stripping fabric dyes. * Requires ≥40 °C to activate.

TAED and NOBS enable oxygen bleach at lower temperatures by converting percarbonate into a more reactive form. They accelerate cleaning even in warm and hot cycles.

Premium detergents include polymers that keep dirt suspended, preventing redeposition during rinse cycles.

When used for soaking, boosters perform similarly. In‑wash, their formulation makes a major difference.

Oxygen bleach (with or without activator), surfactants for reinforcement, enzymes (lipase in premium types), and water conditioners.

* To add lipase when detergent lacks it. * To add oxygen bleach with liquids/pods. * Budget versions omit cold‑wash activators.

* Vanish:

• Base “Oxi” = no lipase.
• Gold / Gold Pro = include lipase and TAED.
• Gold Pro granules dissolve fastest—ideal for short cycles.

* Sard:

• All powders include lipase, no cold activator (≥40 °C needed).
• Super Power is strongest and roughly half the price of Vanish.

* Supermarket Brands (Aldi, Coles, Woolworths):

• Basic bleach + protease + amylase, no lipase.
• Only Coles Ultra Oxy Advanced Booster & Soaker contains TAED (low concentration).

Premium powders already include oxygen bleach, activators, enzymes, and builders, so boosters add no benefit.

Liquids/pods cannot contain percarbonate, so boosters serve as both oxygen bleach and lipase source.

Pretreatment sprays are effective—store brands often match or beat name ones. Apply and allow at least five minutes before the wash. Only needed for known heavy stains.

Choice performs comparative testing with four front loaders and four top loaders on ~20 °C tap‑cold cycles. However, they do not publish wash‑phase durations. Enzymes require 15–25 minutes agitation to activate.

Top‑loader (impeller) results appear much worse than front‑loader performance, partly due to machine design differences. Choice representatives previously claimed to test with agitators, though footage later revealed impellers.

Weighting bias: human grime = 20 %, combined food stains = 12 %, favouring food‑specific detergents. Their stain‑remover tests evaluate *soaking* only, not in‑wash boosting.

Only hazardous ingredients must appear on an SDS, not the full formula. Limited transparency makes it hard to evaluate detergents chemically.
