Mr Muscle, Brillo, Pledge and Glade are some of the many household names owned by SC Johnson & Son. Now the US conglomerate is about to add a decidedly green feather to its cap by acquiring Method and Ecover from People Against Dirty, pending regulatory approval in the US, the UK and Germany. 

The move reflects the greener policies SC Johnson has been promoting over the last few years, including efforts in ingredient transparency. Kelly Semrau, senior vice president of sustainability, says: "We believe Method and Ecover have a strong tradition of innovation and delivering on consumers’ needs. They are a great complement to SC Johnson’s trusted line-up of iconic brands."

Although she is unable to discuss specifics during the required regulatory review, she added: "This acquisition, like all other SC Johnson brands, will follow our Greenlist programme after a period of time."

The Greenlist process was launched in 2001, with the intention of going beyond taking out ‘bad’ ingredients and instead focusing on the use of ‘better’ options. According to the company website, it seeks to continuously improve formulae based on information about the impacts of the ingredients on the environment and human health.

The process includes ratings for all ingredients used globally, other than those in the process of being evaluated. Each receives a rating from three (‘best’), through two (‘better’) and one (‘good’) to zero. Zero-rated materials cannot be intentionally added to new products or can only be used at restricted levels. The company is working to eliminate these materials from existing products as reformulations occur.

Each year, SC Johnson has increased the percentage of its ‘better’ and ‘best’ ingredients, which started at 18% but has now risen to 51%. Later this year, the company has pledged to reveal the science behind Greenlist.

Transparency efforts

Transparency has been a hot topic for the cleaning product industry in the US of late, with pressure from NGOs and consumers for brands to reveal their ingredients.

In September, California passed a bill which will require increased disclosure of intentionally added ingredients in cleaning products, although it allows manufacturers to omit listing any which are considered confidential business information. The final measure’s online disclosure requirements take effect on 1 January 2020, the labelling mandates a year later.

A bill has also been introduced in Congress that would require products to bear a label listing ingredients, and New York has put forward a proposal for manufacturers to publicly disclose ingredients and identify chemicals of concern used in formulations through the Household Cleansing Product Information Disclosure programme.

In the past, SC Johnson has faced direct scrutiny over its transparency efforts or lack of them. A 2011 study commissioned by the NGO Women’s Voices for the Earth (WVE), Dirty secrets: What’s hiding in your cleaning products?, evaluated the content of 20 household products, including several Glade products. It discovered chemicals such as phthalates and the fragrance ingredient galaxolide, as well as some allergens. 

After pressure from WVE, SC Johnson agreed to phase out use of galaxolide earlier this year and is transitioning to macrocyclic musks in new fragrance formulations. The company has also attempted to increase transparency through a number of disclosure initiatives.

Fragrance has long been a particular bone of contention, with industry claiming that disclosure would jeopardise confidential business information and lead to counterfeiting. Recent initiatives by big brands have proved it is possible to meet the demand for full ingredient disclosure.

In 2014, SC Johnson published its fragrance palette, listing 1,300 approved fragrance ingredients, as well as a list of ingredient restrictions. It began by disclosing those for air care, present at concentrations down to 0.09% of the product formula. On average, this could be 10-50 ingredients per product.

For other product categories where fewer fragrance ingredients are used, SC Johnson began listing those present at a concentration of more than 0.09% in the final product or the top ten ingredients, whichever provides the most information for consumers.

Fragrance disclosure

In 2015, SC Johnson began rolling out product-specific fragrance disclosure, expanding its online ingredient disclosure guide for the Glade range. Consumers can access ingredients present at higher concentration values at WhatsInsideSCJohnson.com, the website launched in 2009. There are plans to extend its fragrance disclosure programme to several more cleaning product lines, including Pledge, Windex, Shout and Scrubbing Bubbles.

In 2016, SC Johnson launched Glade Fresh Citrus Blossoms collection, its first product range with 100% fragrance ingredient transparency, down to substance level. This includes scented spray, wax melts and scented oil.

All such ingredients, including essential oils, are disclosed on the website. This will be followed, later this year, by the release of a new Glade product line which is 100% natural and will disclose all ingredients down to component level.

Earlier this year, SC Johnson’s measure to disclose 368 potential skin allergens that may be used in its products was hailed by the NGO Environmental Working Group as a "groundbreaking" move which would set the bar for other companies. It certainly set the stage for a raft of other announcements, including a pledge by competitor Procter & Gamble to reveal the fragrance ingredients, down to 0.01% of content, for all products sold in the US and Canada by the end of 2019.

Consumer products giant, Unilever US, has also now announced plans to provide information about specific fragrance ingredients used in its personal care products by the end of 2018. Details of the first 100 products across seven brands, were made available on an app and online in September.

As the demand from consumers grows to make informed decisions about chemicals in the products they purchase, the pressure for transparency about ingredients looks unlikely to abate. Companies like SC Johnson are at the forefront of rising to this challenge.
