TL;DR: Both Resparkle and Kin Kin Naturals are genuine Australian family businesses making plant-based laundry products. The deciding factors are format, price per wash, and published performance evidence. Kin Kin's 1050ml laundry liquid costs around $0.50 per wash at the standard unit price; Resparkle's Natural Laundry Powder is $0.33. Resparkle publishes an independent lab-test claim against a named benchmark; Kin Kin does not. If you are primarily choosing on Queensland-made provenance and scent-forward liquid formulation, Kin Kin is a defensible choice. If per-wash cost, published performance evidence, and plastic-free packaging are the deciding axes, the data points toward Resparkle.

What this article covers

A head-to-head between two Australian natural laundry brands that share a family-business identity but took different bets on format, proof, and packaging. Below: the format difference (liquid vs powder), per-wash cost math on the same basis, what each brand publishes about performance, the ingredient story, the packaging comparison, and three honest gaps where Resparkle is not the stronger answer.

The format difference: liquid vs powder

Kin Kin Naturals' core laundry product is a liquid. Resparkle's is a powder. That choice shapes almost every other comparison in this article.

Kin Kin Naturals sells an ultra-concentrated laundry liquid in 1050ml bottles and 5L bulk containers, available in Eucalypt & Lemon Myrtle and Lavender & Ylang Ylang variants. Dose is 35ml per full load. The 1050ml bottle yields 30 washes. Felix van der Kooij, who co-founded Kin Kin in 2008 in the Noosa Hinterland with his wife Sandy, developed the formula using his background as a formulator for OMO, the global laundry detergent brand. The product is described as "all natural, family-made in Queensland, and it works." Source: per Kin Kin Naturals' product pages and brand profile.

Resparkle sells a Natural Laundry Powder in a 600g industrially compostable bag, covering 55 washes. Dose is 2 to 3 teaspoons per full load. The brand was started in 2013 at a Mornington Peninsula farmers market and is now run by a small family team based in Brisbane.

Neither brand is a startup-lab exercise. Both are built around genuinely plant-based formulations tested in real household laundry routines. The comparison is a buyer-utility question, not a values question.

Cost per wash: the math on the same basis

This is the clearest quantitative difference between the two brands at the standard unit size.

Resparkle: $18.00 for 600g / 55 washes = $0.33 per wash.

Kin Kin Naturals 1050ml: around $14.95 (based on multiple Australian retailer listings) / 30 washes = around $0.50 per wash. Kin Kin's direct website does not display pricing, so this figure is based on retailer-verified pricing.

That is a 52% higher per-wash cost for Kin Kin at the standard unit size. Kin Kin's 5L bulk pack brings the per-wash cost down to around $0.38 (at 35ml per load, 5L yields approximately 142 washes at $53.95). At bulk, the gap narrows but Resparkle is still lower.

The gap exists because Kin Kin's liquid format carries water as part of its volume. Kin Kin's 1050ml bottle is 35ml per load, meaning the majority of what you are buying and shipping is water. Resparkle's powder strips the water out: 2 to 3 teaspoons of concentrated dry powder per load, 55 loads from a 600g bag. Concentration is where the cost difference comes from.

Performance evidence: what each brand publishes

This is the most material difference for a buyer making a decision on cleaning performance.

Resparkle publishes an independent lab-test claim: independently lab tested to outperform CHOICE's #1-rated supermarket detergent on five common stains. The benchmark is named, the test is independent, and the claim directly addresses the question every eco-laundry buyer asks before switching from a mainstream product: will it actually clean?

Kin Kin Naturals does not publish independent benchmark lab data against a named supermarket detergent as of this article's research date (verified against Kin Kin's own product pages and brand profile). Kin Kin's cleaning claims are formulation-led: coconut-based surfactants free of alcohol ethoxylate, LAS, and SLS; plant-sourced enzymes; essential oils. These are credible chemistry choices; they are not independently benchmarked.

Felix van der Kooij's OMO background is genuinely relevant formulation credential. A former global laundry formulator knows how detergents work. That background does not, on its own, substitute for an independent test result. We think families deserve both: a credentialed formula and the independent proof to back it up.

Ingredients: what each brand puts in and what it publishes

Resparkle publishes per-ingredient EWG hazard ratings on the product page. Every ingredient is rated 1 or 2 on the Environmental Working Group's hazard scale, the lowest two tiers.

Ingredient	EWG	Function
Sodium Carbonate	1	Cleaning and sanitising
Sodium Percarbonate	1	Oxygen bleach
Coconut Surfactant	1	Surfactant
Sodium Carboxymethyl Cellulose	1	Stain remover
Sodium Metasilicate Pentahydrate	2	Builder
Sodium Citrate	1	Chelating
Natural Enzyme Blend	1	Breaks down protein and starches
Essential Oil Blend	n/a	Fragrance (Lemon Eucalyptus variant only)

Kin Kin Naturals publishes its ingredient list with plain-English descriptions but does not publish per-ingredient EWG ratings. The Eucalypt & Lemon Myrtle formula (verified from multiple retailer sources):

Coconut-Derived Anionic and Non-Ionic Surfactants (no alcohol ethoxylate, LAS or SLS)
Rainwater
Potassium Coconut Soap
Potassium Citrate
Enzymes
Organic Eucalypt Essential Oil
Organic Lemon Myrtle Essential Oil
Tangerine Essential Oil

Kin Kin's formulation choices are solidly plant-based. The explicit exclusion of alcohol ethoxylate, LAS, and SLS is a meaningful positive signal. The absence of EWG ratings means a buyer wanting per-ingredient hazard data would need to look up each ingredient themselves.

For more on what EWG ratings mean for eco laundry products, see EWG ratings explained for laundry detergent (when published).

Packaging: compostable vs bottle

Resparkle's packaging is industrially compostable and contains no plastic, not recycled plastic, not rPET, not bioplastic. The 600g powder ships in a plant-fibre bag. After use, bags can be returned via a postage-paid label (10 or more bags triggers the return). The product ships dry, which is why a compostable bag works: dry powder does not attack plant-fibre packaging the way a surfactant-water mix would.

Kin Kin's packaging details were not confirmed on their website at the time of research. The 1050ml bottle is shown in product imagery but material composition is not stated on Kin Kin's product pages. The 5L bulk container reduces per-unit packaging relative to buying multiple 1050ml bottles. Buyers wanting specific packaging material information would need to contact Kin Kin directly.

Scent: where Kin Kin is the stronger answer

If scent is your primary buying criterion, Kin Kin Naturals is the right call. Both variants, Eucalypt & Lemon Myrtle and Lavender & Ylang Ylang, are built around organic Australian essential oils with a notably fresh, natural scent profile. Liquid formats carry essential oils through the wash and rinse cycle more persistently than powders, which is a structural advantage for households where post-wash scent matters.

Resparkle's design choice is different: Lemon Eucalyptus (lightly scented with Australian essential oil) and Fragrance-Free. The fragrance-free option exists specifically for sensitive skin, eczema households, baby clothes, and asthma sufferers. If anyone in your household is reactive to essential oils, Kin Kin's all-scented range may be a less suitable option for those specific loads.

Where Resparkle doesn't win

Three honest gaps, named specifically.

Kin Kin is cheaper at the standard unit. Kin Kin's 1050ml bottle is around $14.95, which looks lower than Resparkle's $18. The per-wash cost goes the other way ($0.50 vs $0.33) because Kin Kin's dose is liquid and includes water weight, but if upfront-spend-per-bottle is the frame your household uses for purchasing decisions, Kin Kin's headline price is lower.
Kin Kin has a stronger essential-oil scent story. Both variants use organic essential oils and the liquid format delivers more scent persistence through the wash. Resparkle's Lemon Eucalyptus is genuinely pleasant but intentionally light.
Kin Kin has a longer heritage. Felix started formulating Kin Kin products in 2008, 5 years before Resparkle was founded. A 17-year track record of independent family formulation is a credible signal. Resparkle's independent lab data is more recent; Kin Kin's formulation experience is longer.

These are real trade-offs. Depending on your household's priorities, Kin Kin may genuinely be the better fit.

Who should pick which

Pick Kin Kin Naturals if:

Scent is your lead criterion and you want strong, persistent essential-oil fragrance.
You specifically want a liquid formula, not a powder.
You value a 17-year formulation track record from a PhD-qualified former OMO formulator.
Your household does not require a fragrance-free option.

Pick Resparkle if:

You want a lower per-wash cost ($0.33 vs $0.50 at standard unit).
You want independent lab-test evidence against a named performance benchmark.
You want per-ingredient EWG hazard ratings published, not left as homework.
You need a fragrance-free option (eczema, asthma, baby clothes, fragrance sensitivity).
Plastic-free packaging is a priority. Resparkle's bag contains no plastic of any kind.
You want an award-backed formula. Resparkle won Gold and Editor's Choice at the 2020 Australian Non-Toxic Awards.

Frequently asked questions

Is Kin Kin Naturals still operating in 2026?

Yes. Kin Kin Naturals is an independent Australian family business based in the Noosa Hinterland, Queensland, and continues to trade as of this article's update date. Their products are available through their website and a range of Australian natural products retailers.

What is the difference between Kin Kin's laundry liquid and a standard laundry powder?

Kin Kin sells a concentrated laundry liquid, not a powder. The key difference is format: Kin Kin's 1050ml bottle is dosed at 35ml per load, meaning the liquid carries water as part of its volume. Resparkle's powder doses at 2 to 3 teaspoons of dry concentrated product, which is why it achieves a lower per-wash cost from a lighter, smaller pack. For a full format comparison, see natural laundry powder vs liquid.

Does Kin Kin Naturals have a fragrance-free option?

No. As of this article's research date, Kin Kin's laundry liquid range is available only in Eucalypt & Lemon Myrtle and Lavender & Ylang Ylang. Both variants are scented with essential oils. Households with eczema, asthma, fragrance sensitivity, or baby clothes requirements may find the all-scented range limiting. Resparkle's Fragrance-Free variant exists specifically for these households.

Is Felix van der Kooij's OMO background a meaningful credential?

Felix van der Kooij spent years as a global formulator for OMO before founding Kin Kin in 2008. That is a genuine technical credential, and it explains why Kin Kin's formula specifically excludes alcohol ethoxylate, LAS, and SLS (the surfactant choices someone with mainstream laundry formulation experience would know to avoid in a natural product). The limitation is that professional formulation experience is not a substitute for independent third-party testing against a named benchmark.
