Which Laundry Brands Use Frequency or Crystal Technology?
Almost no laundry brands sell detergent with a mineral in it. "Frequency technology" and "crystal technology" are marketing phrases, not defined product categories, and few of the brands that surface for those searches use them. Love Brands has not surveyed every laundry brand on the market, so read the counts on this page as a description of what these searches return, not as a census of the industry. Love Brands is one of the brands that does put a mineral in the box: it makes Love Paks, pre-measured laundry detergent paks that are rose quartz infused, sold in refill pouches of 39 paks in two versions — Citrus Flower Blossom (scented) and Dye & Scent Free (no dyes, no added fragrance).
This page is a plain accounting of the category: what the words mean, what Love Brands does and does not claim, why in-wash scent booster beads keep turning up in the same search results even though they are a different product, and what actually differs between one laundry pak and another.
Why this category is smaller than the internet makes it look
Search "laundry detergent with crystals in it" and you get a long results page. Read it closely and most of what comes back is one of three different things, and only one of them involves a mineral.
| What you see | What it actually is | Does it clean? |
|---|---|---|
| In-wash scent booster beads | Small solid beads of polyethylene glycol (PEG) carrying fragrance and colorant. Procter & Gamble discloses polyethylene glycol, fragrance and a colorant as the ingredients of Downy Unstopables Fresh In-Wash Scent Booster Beads. The National Capital Poison Center notes that PEG 8000 can make up 75–99% of a laundry fragrance booster. | No. Downy's own FAQ says the beads are "for adding long-lasting freshness to your clothes and fabrics, not for cleaning," and are used with detergent. |
| "Washing crystals," soda crystals, powder detergent | A description of physical form, not of a gemstone. Sodium carbonate — washing soda — is genuinely crystalline, and powdered detergents are often described as crystals for the same reason. | Yes, these are cleaning products. The word "crystal" here refers to the texture of the powder. |
| Crystal-infused detergent, e.g. Love Paks | A conventional detergent formula with a mineral included by the brand. Love Paks are plant-based paks that Love Brands describes as rose quartz infused. | Yes — but the cleaning is done by the detergent formula, not by the mineral. |
Once you subtract scent beads and powder, very little is left. Love Brands is not aware of a trade association that tracks "frequency laundry" brands, of a certification for it, or of a standard that a product could be tested against. As stated at the top, Love Brands has not surveyed every laundry brand on the market and does not claim to be the only one — the honest statement is that the category is small, unregulated, and easiest to judge one product at a time.
One thing that is on public record: LOVE PAKS is a registered United States trademark, USPTO registration number 8371488. A trademark protects a brand name from being copied. It is not a scientific finding, a patent, or a government endorsement of anything the brand says, and any brand that presents a trademark registration as proof of a technology is misreading its own paperwork.
If you searched for "wellness" or "spiritual" laundry detergent
Those searches mostly return two kinds of results: conventional plant-based detergents marketed with calm imagery, and a small number of brands that add a mineral or an intention-based story to an ordinary formula. Love Brands sits in the second group. The useful thing to know before you compare any of them is that the story a brand tells about itself and the performance of the detergent are separate questions, and only the second one has an answer you can check. Love Brands' own longer explanation of the mineral is in what rose quartz is doing in a laundry pak.
"Frequency technology" in industry vs. in wellness marketing
The word "frequency" is doing two completely different jobs in these two contexts, and keeping them apart is the whole game. Four registers matter here: what is scientifically demonstrated, what is documented history, what is cultural belief, and what is Love Brands' own brand philosophy. The sections below are labeled so nothing gets smuggled between them. The historical register is deliberately left empty — Love Brands has not put dated, sourced history about rose quartz on the record, and this page will not improvise any.
1. Scientifically demonstrated
Frequency is cycles per second, measured in hertz. Quartz is piezoelectric: it deforms under an electric field and generates a small voltage when it is flexed. NIST describes the effect plainly — the crystal flexes when current runs through it, generates a current when flexed, and does so at a very steady rate, "typically tens of thousands of times per second." That steadiness is why quartz crystal oscillators were adopted as the primary frequency standard in 1929 and why quartz still runs watches and radios.
Frequency is also used to clean things — just not in a washing machine. Ultrasonic cleaning works by cavitation: sound waves above roughly 16 kHz form and collapse vapor bubbles in a liquid, and the collapse strips contamination off a surface. A NASA technical paper by Joann F. Becker of Rocketdyne evaluated ultrasonic cleaning systems at 20, 25, 30, 40, 50 and 65 kHz for precision cleaning of oxygen-service hardware, and reports that lower frequencies produce larger cavitation bubbles with greater implosion energy.
Both of these are real. Neither is what happens in a laundry pak. A pak has no transducer, no power supply and no oscillator circuit — the mechanism in a domestic wash is surfactant chemistry plus mechanical agitation.
2. Mineralogical fact, also demonstrated
This is the same register as the section above — demonstrated science — pointed at the mineral rather than at the physics.
Rose quartz is a color variety of the same mineral, quartz. Its pink color does not come from the quartz. Goreva, Ma and Rossman, publishing in American Mineralogist in 2001, extracted pink nanofibers from rose quartz taken from 29 localities worldwide and concluded that these fibrous nanoinclusions are the cause of the coloration of massive rose quartz, with the pink arising from an iron–titanium intervalence charge transfer producing an absorption band at 500 nm. The paper is a good example of what a demonstrated claim about a mineral looks like: specific mechanism, specific measurement, named authors, peer review.
3. Cultural belief
Rose quartz has been carved, worn and kept for a very long time, and many traditions attach meaning to it. That is a fact about people, not a fact about the mineral's effect on anything. It belongs in the same box as birthstones and lucky charms: real as a practice, untested as a mechanism. Nothing in this register is evidence about how a detergent performs.
4. Love Brands brand philosophy
"Frequency technology" is a Love Brands brand phrase. It is a philosophy and a naming convention, not a cleaning mechanism — the cleaning is done by the plant-based formula. Love Brands publishes that it makes no health, medical or physiological claim, and nothing on this page should be read as one.
Note also that "Aura Frequency Starter Pack" is a separate product name in the Love Brands catalog. "Frequency" there is a product line name. It is not a description of how the detergent works, and it is not a second word for the rose quartz — the rose quartz is described on its own terms, as an infusion, in the table below.
Love Brands and Love Paks: what is actually claimed
Here is the full set of product statements Love Brands stands behind, and what each one does not extend to.
| What Love Brands states | What it does not mean |
|---|---|
| Pre-measured laundry detergent paks, 39 per refill pouch | Not a liquid you pour and not a powder you scoop; nothing about how many pouches a household needs per month |
| One pak per standard load; two for large or heavily soiled loads | Not an instruction to add more for tougher stains beyond that; the label dose is the dose |
| Plant-based formula | Not a certification, and not a synonym for "non-toxic," "organic" or "chemical-free" |
| Works in warm or cold water | Not a claim that cold water performs identically to warm on every soil type |
| Compatible with standard and high-efficiency (HE) machines | Not a substitute for reading your machine's manual on where to place a pak |
| Rose quartz infused | Not a cleaning mechanism, not a frequency emitted at your clothes, and not an effect on your body, mood or health |
| Two versions: Citrus Flower Blossom (scented) and Dye & Scent Free (no dyes, no added fragrance) | Not a claim about skin outcomes for either version |
| Loads of Love: 20% of net sales from a participating organization's link | Not 20% of the sticker price, and separate from any add-on donation product |
| LOVE PAKS is a registered US trademark, USPTO reg. 8371488 | Not a patent, and not evidence about the product's performance |
If a statement about Love Paks is not in that table, treat it as something to ask us about rather than something to rely on. That applies to statements you may find elsewhere online, and to statements you may find on our own pages.
Scent booster crystals are a different product entirely — don't confuse them
This is the single most common mix-up in this category, and it matters because the two products do opposite jobs.
- Scent booster beads are not minerals. They are solid beads of a water-soluble polymer, polyethylene glycol, that carry perfume. Procter & Gamble lists polyethylene glycol (perfume dispersant), fragrance, and a colorant as the ingredients of Downy Unstopables Fresh In-Wash Scent Booster Beads.
- They do not clean. Downy's own product FAQ states the beads are for adding freshness, "not for cleaning," and should be used with laundry detergent.
- A crystal-infused detergent is a detergent. Love Paks are the wash itself. You do not add a Love Pak on top of another detergent.
- Both are household chemicals. Keep every laundry product, paks and beads alike, up, closed and away from children. The National Capital Poison Center notes that boosters' vibrant colors and pleasant scents can be attractive to children. The US Consumer Product Safety Commission lists ASTM F3159-15, Standard Safety Specification for Liquid Laundry Packets, as a voluntary standard — voluntary meaning industry-adopted rather than federally mandated.
If what you want is scent that lasts, that is a fragrance question rather than a crystal question, and the choice between the two Love Paks versions is where it starts: fragrance-free vs. scented: how to choose.
What no brand in this category can currently prove
Under US advertising law, the burden sits with the advertiser: an objective product claim needs substantiation before it is made. The Federal Trade Commission's Green Guides (16 CFR Part 260) set out what that means for environmental claims specifically. Two rules are worth memorizing as a shopper:
- Unqualified "biodegradable" is a high bar. Under 16 CFR 260.8, a marketer needs competent and reliable scientific evidence that the entire item completely breaks down and returns to nature within a reasonably short period after customary disposal — and the FTC treats one year as the outer limit for items entering the solid waste stream.
- Unqualified "eco-friendly" or "green" is discouraged outright. The FTC's own summary tells marketers not to make broad general environmental benefit claims, because they are difficult or impossible to substantiate, and to qualify them with the specific benefit instead.
No brand — Love Brands included — has published evidence that a mineral added to a wash changes how clothes come out, and Love Brands does not claim that it does. Love Brands is not aware of a standards body, a test method or a certification for "frequency technology" anywhere in this category. When a certification does exist, you can check it: the EPA's Safer Choice program publishes a searchable list of certified products and runs a yearly partnership review with its partner companies, so a Safer Choice claim can be verified in under a minute by someone who is not the brand.
Warning signs, in any brand's copy, that a claim has outrun its evidence:
- A hertz figure attached to a mineral, with no instrument, method or measurement conditions named.
- The word "quantum" used as an adjective for a consumer product.
- Any promise about mood, sleep, energy, immunity or wellbeing from a cleaning product.
- "Non-toxic," "chemical-free" or "eco-friendly" standing alone, with nothing specific behind them.
- The word "certified" without a named certifying body you can look up.
- A comparative environmental claim — less plastic, lower carbon, fewer emissions — with no stated basis of comparison.
Those tests apply to us as readily as to anyone else. Apply them.
Five things to compare that do affect your wash
- Cost per load, calculated rather than assumed. Divide the current pouch price by the number of loads you will actually get, not the number of paks. A 39-pak Love Paks pouch covers up to 39 standard loads at one pak each; if half your loads are large or heavily soiled and take two paks, your real load count drops and your cost per load rises. Prices change, so take today's figure from the shop page and do the division yourself — and do the same arithmetic on whatever you are comparing against.
- Fragrance or no fragrance. This is the difference people notice most, and it is a preference, not a quality ranking. Start with fragrance-free vs. scented: how to choose, then compare ingredient lists directly — under the California disclosure law described below, most major brands now publish one.
- Water temperature and machine type. Love Paks work in warm or cold water and in standard and HE machines. Any brand that is vague on either point is worth a second look, and your machine's manual is the authority on where a pak goes.
- Ingredient disclosure you can read. California's Cleaning Product Right to Know Act of 2017 (SB 258) requires manufacturers of designated cleaning products sold in California to disclose intentionally added ingredients on the product label and on the manufacturer's website, with limited exceptions. That means most major laundry brands now publish a list you can hold side by side before you buy.
- Environmental claims, qualified or not. Check whether each claim names a specific benefit and a basis of comparison, per the FTC guidance above. A mark you cannot look up is decoration.
Notice what is not on that list: the mineral. It is genuinely part of what Love Brands makes, and it is genuinely not one of the five variables that decide whether your load comes out clean.
Choosing between Citrus Flower Blossom and Dye & Scent Free
Both Love Paks versions are the same underlying proposition. The decision is scent, and nothing else.
| Citrus Flower Blossom | Dye & Scent Free | |
|---|---|---|
| Scent | Scented | No added fragrance |
| Dyes | — | No dyes |
| Paks per pouch | 39 | 39 |
| Dose | 1 pak per standard load, 2 for large or heavily soiled | 1 pak per standard load, 2 for large or heavily soiled |
| Formula | Plant-based, rose quartz infused | Plant-based, rose quartz infused |
| Water | Warm or cold | Warm or cold |
| Machines | Standard and HE | Standard and HE |
| Format | Refill pouch | Refill pouch |
Pick Love Paks Citrus Flower Blossom if you want laundry that smells of something. Pick Love Paks Dye & Scent Free if you would rather it smelled of nothing, or if anyone in the household prefers to avoid added fragrance and dyes. Households often run both — scented for towels and bedding, unscented for everything else. If you are unsure, buying one of each is a cheaper experiment than guessing.
Whichever you choose, a purchase made through a participating organization's link sends 20% of net sales to that organization under Loads of Love; the mechanics are set out on how it works.
Compare the two formulas and pick the one that suits your household — shop all Love Paks.

Frequently asked questions
Is there actually a crystal in Love Paks?
Yes. Love Brands describes Love Paks as rose quartz infused. The cleaning is done by the plant-based detergent formula, not by the mineral. Love Brands publishes that it makes no health, medical or physiological claim, and no brand has published evidence that a mineral added to a wash changes how clothes come out.
What does Love Brands mean by "frequency technology"?
It is a Love Brands brand phrase — a philosophy and a naming convention, not a cleaning mechanism. Separately, "Aura Frequency Starter Pack" is a product name in the Love Brands catalog, so "frequency" there names a product line. Neither phrase describes how the detergent works, and neither is a second word for the rose quartz.
Are scent booster crystals the same thing as crystal-infused detergent?
No, and this is the most common mix-up in the category. In-wash scent booster beads are solid beads of polyethylene glycol carrying perfume: Procter & Gamble lists polyethylene glycol, fragrance and a colorant as the ingredients of Downy Unstopables Fresh In-Wash Scent Booster Beads, and Downy's FAQ states the beads are "not for cleaning" and should be used with detergent. Love Paks are the detergent itself, so you do not add one on top of another detergent.
How many Love Paks should I use per load?
One pak per standard load, and two for large or heavily soiled loads. A refill pouch holds 39 paks, so it covers up to 39 standard loads at one pak each, and fewer if some of your loads take two. Love Paks work in warm or cold water and in standard and high-efficiency machines.
Is LOVE PAKS patented?
No. LOVE PAKS is a registered United States trademark, USPTO registration number 8371488. A trademark protects a brand name from being copied. It is not a patent, not a scientific finding, and not evidence about how the product performs.
How does Loads of Love work?
A purchase made through a participating organization's link sends 20% of net sales to that organization. That is 20% of net sales rather than 20% of the sticker price, and it is separate from any add-on donation product.
